Chapter 1 - System Description
1.1
Introducing BreezeACCESS VL
BreezeACCESS VL is a high capacity, IP services oriented Broadband Wireless
Access system. The system employs wireless packet switched data technology to
support high-speed IP services including fast Internet and Virtual Private
Networks. BreezeACCESS VL users are provided with a network connection that
is always on, supporting immediate access to the Internet and other IP services at
high data rates. The system is designed for cellular-like deployment, enabling the
system architecture to vary in size and structure. A system can include any
number of cells, each containing several Access Units for better coverage of
densely populated areas.
BreezeACCESS VL can support sensitive applications through authentication
and/or data encryption utilizing WEP or AES algorithm with 128-bit keys. FIPS
(Federal Information Processing Standards) 197 certified encryption algorithm is
optionally available for Access Units with HW revision C and higher (except to
AUS units). The system supports Virtual LANs based on IEEE 802.1Q, enabling
secure operation and Virtual Private Network (VPN) services and enabling teleworkers or remote offices to conveniently access their enterprise network. The
system supports layer-2 traffic prioritization based on IEEE 802.1p and layer-3
traffic prioritization based on either IP ToS Precedence (RFC791) or DSCP
(RFC2474). It also supports traffic prioritization based on UDP and/or TCP port
ranges. In addition, it may use the optional Wireless Link Prioritization (WLP)
feature to fully support delay sensitive applications, enabling Multimedia
Application Prioritization (MAP) for high performance voice and video. The
implementation of MAP through the unique WLP protocol revolutionizes the
business model by increasing, for example, the number of simultaneous VoIP
calls per sector by as much as 500%.
BreezeACCESS VL products operate in unlicensed frequency bands in Time
Division Duplex (TDD) mode, using Orthogonal Frequency Division Multiplexing
(OFDM) modulation with Forward Error Correction (FEC) coding. Using the
enhanced multi-path resistance capabilities of OFDM modem technology,
BreezeACCESS VL enables operation in near and non-line-of-sight (NLOS)
environments. These qualities enable service providers to reach a previously
inaccessible and broader segment of the subscriber population.
BreezeACCESS VL is designed to enable construction of “mixed” cells, where it
can be used together with other BreezeACCESS products using GFSK
modulation, including BreezeACCESS II, BreezeACCESS MMDS, BreezeACCESS
XL and BreezeACCESS V.
BreezeACCESS VL products are currently available in the following frequency
bands:

The available frequencies, as well as other parameters, depend on applicable local
regulations. The actual operating frequencies used by the system can be
configured according to applicable radio regulations and specific deployment
considerations.
A BreezeACCESS VL system comprises the following:
„ Customer Premise Equipment (CPE): BreezeACCESS VL Subscriber Units
(SUs).
„ Base Station Equipment (BS): BreezeACCESS VL Access Units and
supporting equipment.
„ Networking Equipment: Standard Switches/Routers supporting connections
to the backbone and/or Internet.
„ Management Systems: SNMP-based Management, Billing and Customer
Care, and other Operation Support Systems.

Chapter 1 - System Description
1.2
Base Station Equipment
The Access Units, installed at the Base Station site, provide all the functionality
necessary to communicate with the Subscriber Units and to connect to the
backbone of the Service Provider.
There are 2 lines of Access Units with different architectures:
„ Modular Base Station Equipment
„ Standalone “Micro-Cell” Access Unit
1.2.1
Modular Base Station Equipment
The Base Station Equipment is based on the BS-SH 3U chassis, which is suitable
for installation in 19-inch racks. The chassis contains one or two Power Supply
modules and has 8 slots that can accommodate BS-AU Network Interface
modules. These slots can also
accommodate various combinations of
other modules, including Network
Interface (BS-AU) modules for Access
Units operating in any of the bands
supported by BreezeACCESS equipment
using GFSK modulation, including BreezeACCESS II, BreezeACCESS MMDS,
BreezeACCESS XL and BreezeACCESS V. It can also accommodate a BS-GU GPS
and Alarms module to support GPS-based synchronization of BreezeACCESS
systems using Frequency Hopping radios.
Two different types of power supply modules are available for the BreezeACCESS
VL modules: The BS-PS-DC that is powered from a -48 VDC power source, and
the BS-PS-AC, powered from the 110/220 VAC mains. The optional use of two
power supply modules ensures fail-safe operation through power supply
redundancy. When the same chassis is used also for Access Unit modules
belonging to other BreezeACCESS families using GFSK modulation, then one
BS-PS power supply (AC or DC) should be used to provide power to the
BreezeACCESS VL Access Units, and a different power supply module, suitable

The BS-AU indoor module connects to the network through a standard IEEE
802.3 Ethernet 10/100BaseT (RJ 45) interface. The indoor module is connected
to the outdoor unit via a Category 5E Ethernet cable. This cable carries Ethernet
traffic between the indoor module and the outdoor unit, and also transfers power
(54 VDC) and control from the indoor module to the outdoor unit.
1.2.2
Standalone “Micro-cell” Access Unit
The standalone AU-E-SA Access Unit is very similar to the AU-E-BS unit. The
difference is in the structure of the indoor part; in the AU-ESA Access Unit the indoor unit is a standalone desktop or
wall-mountable unit (the same Universal IDU that is also used
in the SU) rather than a 19” module.
There are two types of Standalone Access Units, differing in
the maximum number of Subscriber Units that they can serve:
„ The AU-SA Access Unit can serve up to 512 Subscriber
Units (124 when Data Encryption is used).
„ The AUS-SA Access Unit can serve up to 8 SUs except SU-54 (refer to section
1.3 for details on availability of SU types in different bands). Optionally, it

is available. SU-54 is not available in the 0.9 GHz band).
NOTE
For convenience, all references to AU-SA are applicable also for AUS-SA, unless explicitly stated
otherwise.
The IDU connects to the network through a standard IEEE 802.3 Ethernet
10/100BaseT (RJ 45) interfaces and is powered from the 110/220 VAC mains.
The indoor unit is connected to the outdoor unit via a Category 5 Ethernet cable.

Subscriber Unit
The Subscriber Unit (SU) installed at the customer premises enables the
customer data connection to the Access Unit. The Subscriber Unit provides an
efficient platform for high speed Internet and Intranet services. The use of packet
switching technology provides the user with a connection to the network that is
always on, enabling immediate access to services.
There are two types of Subscriber Units:
„ The SU-A/E series, where each unit comprises an Indoor Unit and an
Outdoor Unit (with or without an integrated antenna). These products are
intended for installation by a professional installer, enabling long-range
connectivity.
„ The SU-I series of all-indoor Subscriber Unit, intended for installation by nonprofessional end users in locations that are close to the Base Station.
In addition, there is a special variant of a Subscriber Unit, the SU-E-BS, where
the indoor unit is designed for installation in the Base Station chassis. The
SU-E-BS is intended primarily for backhauling or similar applications.
The following sections provide additional details on the various types of
Subscriber Units.
1.3.1
SU-A/E Subscriber Units
The SU-A/E Subscriber Unit comprises a desktop or wall-mountable Indoor Unit

BreezeACCESS VL System Manual
Equipment Positioning Guidelines
2.2
Equipment Positioning Guidelines
This section provides key guidelines for selecting the optimal installation
locations for the various BreezeACCESS VL system components.
CAUTION
ONLY experienced installation professionals who are familiar with local building and safety codes
and, wherever applicable, are licensed by the appropriate government regulatory authorities should
install outdoor units and antennas.
Failure to do so may void the BreezeACCESS VL product warranty and may expose the end user
or Service Provider to legal and financial liabilities. Alvarion and its resellers or distributors are not
liable for injury, damage or regulation violations associated with the installation of Outdoor Units or
antennas.
Select the optimal locations for the equipment using the following guidelines:
„ The outdoor unit can be either pole or wall mounted. Its location should
enable easy access to the unit for installation and testing.
„ The higher the placement of the antenna, the better the achievable link
quality.
„ AU-ODU units should be installed as close as possible to the antenna.
„ The antenna connected to the AU-ODU unit, should be installed so as to
provide coverage to all Subscriber Units (SUs) within its service area.
NOTE
The recommended minimum distance between any two antennas serving adjacent sectors is 2
meters. The recommended minimum distance between two antennas serving opposite cells
(installed back-to-back) is 5 meters.
„ The antenna of the SU (integrated or external)) should be installed to provide
a direct, or near line of sight with the Base Station antenna. The antenna
should be aligned to face the Base Station.
„ In some cases it might be necessary to up/down-tilt the antenna. An optional
Tilt accessory for the ODU providing a tilt range of +/-15° is available from
Alvarion. The tilt option might be necessary to either improve the link
conditions or, if the SU is too close to the Base Station, to reduce the receive
signals strength. As a rule of thumb, if the SU is located at a distance of less
than 300 meters from the Base Station, it is recommended to up-tilt the
antenna by approximately 10° to 15° (especially in line-of-sight conditions) to
avoid saturation of the receivers by too strong signals.
Installation
39
Chapter 2 - Installation
„ The indoor equipment should be installed as close as possible to the location
where the indoor-to-outdoor cable enters the building. The location of the
indoor equipment should take into account its connection to a power outlet
and the customer’s equipment.

2.3
Installing the Outdoor Unit
The following sections describe how to install the outdoor units, including pole
mounting the ODU, and connecting the indoor-to-outdoor, grounding and RF
cables.
NOTE
Ensure that outdoor units, antennas and supporting structures are properly installed to eliminate
any physical hazard to either people or property. Make sure that the installation of the outdoor unit,
antenna and cables is performed in accordance with all relevant national and local building and
safety codes. Even where grounding is not mandatory according to applicable regulation and
national codes, it is highly recommended to ensure that the outdoor unit and the antenna pole
(when using external antenna) are grounded and suitable lightning protection devices are used so
as to provide protection against voltage surges and static charges. In any event, Alvarion is not
liable for any injury, damage or regulation violations associated with or caused by installation,
grounding or lightning protection.
2.3.1
Pole Mounting the Outdoor Unit
NOTE
This section is not applicable for the new, smaller size ODUs. For details on pole mounting the new
ODUs refer to section 2.3.2.
The Outdoor Unit can be mounted on a pole using one of the following options:
„ Special clamps and threaded rods are supplied with each unit. There are two
pairs of threaded holes on the back of the unit, enabling to use the special
clamps for mountingthe unit on diverse pole diameters.
„ Special grooves on the sides of the unit enable the use of metal bands to
secure the unit to a pole. The bands must be 9/16 inches wide and at least 12
inches long. The metal bands are not included with the installation package.
NOTE
Be sure to mount the unit with the bottom panel, which includes the LED indicators, facing

Aligning the Subscriber Unit Antenna
NOTE
This antenna alignment process described in this section is applicable to both the SU-A-ODU and
the SU-I antenna, unless stated otherwise.
The SNR bar display is located on the bottom panel of the SU-A-ODU/front panel
of the SU-I indoor unit. The ten LEDs indicate the quality of the received signal.
The higher the number of green LEDs indicating On, the higher the quality of the
received signal. This section describes how to align the Subscriber Unit antenna
using the SNR bar display.
NOTE
Antenna alignment using the SNR bar display is possible only after the Subscriber Unit is
associated with an Access Unit. The associated Access Unit must be operational and the basic
Subscriber Unit parameters must be correctly configured. Otherwise, the unit will not be able to
synchronize with the Access Unit. As the SNR measurement is performed on received frames, its
results are meaningless unless the Subscriber Unit is associated with an Access Unit.
To align the Subscriber Unit antenna:
1
Align the antenna by pointing it in the general direction of the Base Station.
2
Verify that the power indication of the unit (
3
Verify that the W-LINK LED (
/
/
)is On.
) of the ODU is On, indicating that the unit
is associated with an Access Unit. If the W-LINK LED is Off, check that the
ESSID and Frequency parameters are correctly configured. If the SU is still
not associated with the AU, increase the transmit power level to its maximum
value. If the unit is still not associated with the AU, improve the quality of the
link by changing the direction of the antenna or by placing the antenna at a
higher or alternate location.
4
Rotate the antenna until the maximum SNR reading is achieved, where at
least 1 green LED is on. If you encounter prolonged difficulty in illuminating
the minimum required number of green LEDs, try to improve the reception
quality by placing the antenna at a higher point or in an alternate location.
5
Ensure that the front of the antenna is always facing the Base Station.
However, in certain conditions, such as when the line of site to the Base
Station is hampered, better reception may be achieved using a reflected
signal. In this case, the antenna is not always directed toward the Base
Station.
6
Secure the unit firmly to the pole (SU-A-ODU)/fasten the rotation screws (SUI antenna).

BreezeACCESS VL System Manual
Aligning the Subscriber Unit Antenna
NOTE
In some cases, the antenna may need to be tilted to ensure that the level at which the SU receives
transmissions from the AU (and vice versa) is not too high. As a rule of thumb, if the SU is located
at a distance of less than 300 meters from the AU, it is recommended to up-tilt the antenna by
approximately 10° to 15°. To guarantee a safety margin from the saturation level, the SNR should
not be higher than 50 dB. The orange LED of the SNR bar indicates that the SNR is higher than
50 dB.

3.4
Configuring the Subscriber Unit’s
Maximum Modulation Level
This section describes how to configure the maximum modulation level for
Subscriber Units.
NOTE
If the unit is associated with the AU, then the final configuration of the Maximum Modulation Level
parameter may be performed remotely, for example, from the site of the AU or from another site.
To configure the Maximum Modulation Level:
1
If the SNR of the SU at the AU is too low, it is recommended that you
configure the Maximum Modulation Level parameter to a value that is lower
than the maximum supported by the unit. This can decrease the number of
retransmissions due to attempts to transmit at modulation levels that are too
high for the actual quality of the link.
2
Check the SNR of the SU at the AU. You can use Telnet to view the SNR
values in the MAC Address Database, which can be accessed from the Site
Survey menu. If the ATPC algorithm is not enabled in both AU and SU, the
test should be done with the Initial Power Level at the SU configured to its
maximum value. If the SNR is lower than the values required for the
maximum modulation level according to Table 3-3, it is recommended that
you decrease the value of the Maximum Modulation Level.
NOTE
The SNR measurement at the AU is accurate only when receiving transmissions from the
applicable SU. If necessary, use the Ping Test utility in the Site Survey menu to verify data
transmission.
3
78
Configure the Maximum Modulation Level according to Table 3-3, using the
typical SNR values. It is recommended that a 2 dB margin be added to
compensate for possible measurement inaccuracy or variance in the quality of
the link.

„ Unit MAC Address: The unit's unique IEEE MAC address.
„ Current Number of Associations (AU only): The total number of SUs
associated with this AU. This number may include units that are not
currently active or associated.
NOTE
An SU is only removed from the list of associated SUs under the following conditions:
„ The SU failed to respond to 100 consecutive data frames transmitted by the AU and is
considered to have "aged out".
„ During the last 6 minutes (or more) the SU did not transmit any data frame, and failed to
respond to certain frames that typically are transmitted by the AU every 10 seconds. Since the
sampling interval for this state is about 10 minutes, it means that the decision to remove the SU
from the Associations Database will take place between 6 to 16 minutes from the time the SU
ceased sending data or responding to these “keep-alive” frames (for AUS the sampling interval
is 1 minute, meaning decision time of 6 to 7 minutes).
„ Number of Associations Since Last Reset: For SUs - displays the total
number of associations with any AU since the last reset, including duplicate
associations with the same AU. For AUs - displays the number of SUs that
have associated with the AU since the last reset, including duplicate
associations with the same SU.

options:
„ Display Counters: Select this option to display the current value of the
Ethernet and wireless link (WLAN) counters.
„ Reset Counters: Select this option to reset the counters.
4.2.5.1.1
Ethernet Counters
The unit receives Ethernet frames from its Ethernet port and forwards the frames
to its internal bridge, which determines whether each frame should be
transmitted to the wireless medium. Frames discarded by the unit's hardware
filter are not counted by the Ethernet counters. For units with HW revision B and
lower, the maximum length of a regular IEEE 802.1 Ethernet packet that can be
accepted from or transmitted to the Ethernet port is 1514 bytes, excluding CRC
and VLAN(s). For units with HW revision C and higher, the maximum length of an
Ethernet packet that can be accepted from or transmitted to the Ethernet port
(excluding CRC) is 1600 bytes, including VLAN(s) for single or double-tagged
packets.
The unit transmits valid data frames received from the wireless medium to the
Ethernet port, as well as internally generated frames, such as responses to
management queries and pings received via the Ethernet port.
The Ethernet Counters include the following statistics:
„ Total received frames via Ethernet: The total number of frames received
from the Ethernet port. This counter includes both invalid frames (with errors)
and valid frames (without errors).
BreezeACCESS VL System Manual
114
Menus and Parameters
„ Transmitted wireless to Ethernet: The number of frames transmitted by the
unit to the Ethernet port. These are generally frames received from the
wireless side, but also include frames generated by the unit itself.
4.2.5.1.2
WLAN Counters
The unit submits data frames received from the Ethernet port to the internal
bridge, as well as self generated control and wireless management frames. After a
unicast data frame is transmitted, the unit waits for an acknowledgement (ACK)
message from the receiving unit. Some control and wireless management frames,
as well as broadcast and multicast frames sent to more than one unit, are not
acknowledged. If an ACK is not received after a predefined time, which is
determined by the Maximum Cell distance parameter, the unit retransmits the
frame until an ACK is received. If an ACK is not received before the number of
retransmissions has reached a maximum predefined number, which is
determined by the Number of HW Retries parameter, the frame is dropped.
Each packet to be transmitted to the wireless link is transferred to one of three
queues: Low, Medium and High. Packets in the High queue have the highest
priority for transmission, and those in the Low queue have the lowest priority.
The packets in the High queue will be transmitted first. When this queue is
emptied, the packets in the Medium queue will be sent. Finally, when both the
High and Medium queues are empty, the packets in the Low queue will be sent.
Data packets are routed to either the High or Low queue, according to the queue
selected for them before the MIR/CIR mechanism (for more information see
section 4.2.6.6.3).
Broadcasts/multicasts are routed to the Medium queue (applicable only for AU).
Control and wireless management frames generated in the unit are routed to the
High queue.
Any frame coming from the Ethernet port, which is meant to reach another
BreezeACCESS VL unit via the wireless port (as opposed to messages intended for
stations behind other BreezeACCESS VL units), is sent to the High queue,
regardless of the priority configuration.
The Wireless Link Counters include the following statistics:
„ Total transmitted frames to wireless: The number of frames transmitted to
the wireless medium. The total includes one count for each successfully
transmitted unicast frame (excluding retransmissions), and the number of
transmitted multicast and broadcast frames, including control and wireless
management frames. In the AU, there are also separate counters for the
following:
‘ Beacons (AU only)
Operation and Administration
115
Chapter 4 - Operation and Administration
‘ Management and Other Data frames, including successfully transmitted
unicast frames and multicast/broadcast data frames (excluding
retransmissions, excluding Beacons in AU)
„ Total Transmitted Unicasts (AU only): The number of unicast frames
successfully transmitted to the wireless medium, excluding retransmissions.
This count is useful for calculating the rates of retransmissions or dropped
frames, as only unicast frames are retransmitted if not acknowledged.
„ Total submitted frames (bridge): The total number of data frames submitted
to the internal bridge for transmission to the wireless medium. The count
does not include control and wireless management frames, or
retransmissions. There are also separate counts for each priority queue
through which the frames were routed (High, Mid and Low).
„ Frames dropped (too many retries): The number of dropped frames, which
are unsuccessfully retransmitted without being acknowledged until the
maximum permitted number of retransmissions. This count includes dropped
data frames as well as dropped control and wireless management frames.
„ Total retransmitted frames: The total number of retransmissions, including
all unsuccessful transmissions and retransmissions.
„ Total transmitted concatenated frames: The total number of concatenated
frames transmitted successfully to the wireless medium, excluding
retransmissions. There are also separate counts for concatenated frames that
include one frame (Single), two frames (Double) or more than two frames
(More). For more details refer to section 4.2.6.5.9.
„ Total Tx events: The total number of transmit events. Typically,
transmission events include cases where transmission of a frame was delayed
or was aborted before completion. The following additional counters are
displayed to indicate the reason for and the nature of the event:
‘ Dropped: The number of dropped frames, which are unsuccessfully
retransmitted without being acknowledged until the maximum permitted
number of retransmissions.
‘ Underrun: The number of times that transmission of a frame was aborted
because the rate of submitting frames for transmission exceeds the
available transmission capability.
‘ Others: The number of frames whose transmission was not completed or
delayed due to a problem other than those represented by the other
counters.

4.2.5.3.1
Continuous Average SNR/RSSI Display
The Continuous Average SNR Display option displays continuously updated
information regarding the average quality of the received signal, using Signal to
Noise Ratio (SNR) and Received Signal Strength Indication (RSSI) measurements.
The average RSSI is calculated using the formula:
NewAvgRSSI = (PrevAvgRSSI*HistWeight) + CrtRSSI*(1 – HistWeight ), where:
„ NewAvgRSSI = New Average RSSI
„ PrevAvgRSSI = Previous Average RSSI
„ CrtRSSI = RSSI of the current packet
„ HistWeight = History Weight
The History Weight is given by the next formula:
HistWeight = 0.9 / ( PastTime / 2SNR_Memory_Factor + 1 ), where
PastTime = time between the current packet and previous packet, in seconds
SNR_Memory_Factor = the Average SNR Memory Factor configurable parameter
(see Average SNR Memory Factor on page 186.
The SNR_Memory_Factor can be -1 in this case the history is not used and the
Average RSSI is the RSSI of the current packet.
The same formula is used also for calculating Average SNR (SNR values are used
instead of RSSI values).

LQI = (0.9 x ”Previous LQI”) + (0.1 x ”Last Successful Modulation Level”).
Operation and Administration
119
Chapter 4 - Operation and Administration
Each successful transmit will be included in this average, by using the
modulation level in which the frame was successfully transmitted as the “Last
Successful Modulation Level”.
In order to receive quick and reliable LQI measurements, there should be
sufficient traffic between the SU and the AU. It is recommended to have traffic of
at least 100 packets per second. The traffic can be generated either by an
external utility (FTP session, ping generator, etc.) or by the Ping Test option in the
Site Survey menu with the appropriate settings (see section 4.2.5.2).
NOTE
If Limited Test is indicated next to the LQI results, it means that the results may not indicate the true
quality, as not all modulation levels from 1 to 8 are available. The limitation may be due to the HW
of the unit (HW Revision A), or the applicable parameters in the country code, or the configurable
Maximum Modulation Level parameter.

Country Code and Sub-Bands
Each country has its own regulations regarding operation modes and parameters
such as allowable frequencies and bandwidth, the need to employ an automatic
mechanism for detection and avoidance of frequencies used by radar systems,
maximum transmit power at each of the supported modulation levels and the
ability to use burst transmissions. To efficiently manage these country dependent
parameters, each unit has a ‘Country Code’ parameter and a set of accompanying
parameters, which depend on this country code. Where more than one set of
parameters can be used, the available sets are defined as Sub-Bands, selectable
through the Frequency configuration menu.
4.2.6.2.2
ESSID Parameters
The ESSID (Extended Service Set ID) is a string used to identify a wireless
network and to prevent the unintentional merging of two wireless networks or two
sectors in the same network. Typically, a different ESSID is defined for each AU.
To facilitate easy addition of SUs to an existing network without a prior
knowledge of which specific AU will serve it, and to support the Best AU feature,
a secondary "global" ESSID, namely "Operator ESSID", can be configured in the
AU. If the Operator ESSID Option is enabled at the AU, the Beacon frames
transmitted by it will include both the ESSID and Operator ESSID. The SU shall
BreezeACCESS VL System Manual
130
Menus and Parameters
regard such frames if either the ESSID or the Operator ESSID matches it own
ESSID. The ESSID of the AU with which the SU is eventually associated is
defined as the Run-Time ESSID of the SU. Typically, the initial ESSID of the SU
is configured to the value of the Operator ESSID. When the SU has become
associated with a specific AU, its ESSID can be reconfigured to the value of the
ESSID of the AU.
4.2.6.2.2.1 ESSID
The ESSID parameter defines the ESSID of the unit.
Valid values: A string of up to 31 printable ASCII characters.
The default value is ESSID1.

NOTE
The Operator ESSID string is case sensitive.
4.2.6.2.3
Frequency Definition Parameters
4.2.6.2.3.1 Sub-Bands and Frequency Selection
Each unit is delivered with one or more pre-configured Sub-Bands, according to
the country code. These sets of parameters include also the frequencies that can
be used and the bandwidth.
The parameters that determine the frequency to be used are set in the AU. If
more than one Sub-Band is available, the sub-band to be used can be selected. If
only one Sub-Band is supported, then the sub-band selection option is not
Operation and Administration
131
Chapter 4 - Operation and Administration
available. The SU should be configured with a minimal set of parameters to
ensure that it will be able to automatically detect and use the
frequency/bandwidth used by the AU, including possible changes in this
frequency (Automatic Sub Band Select feature).
To simplify the installation process the SU scans a definable frequencies subset
after power-up. The defined frequencies subsets may include frequencies from
more than one Sub-Band, enabling automatic detection of both frequency and
bandwidth. If the Best AU feature is enabled, the SU will scan the defined subset
and the operating frequency/bandwidth will be determined by the Best AU
mechanism (including the optional use of the Preferred AU feature). Otherwise
the SU will try to associate with the first AU it finds. If no AU is found, the SU will
start another scanning cycle.
4.2.6.2.3.2 Avoiding Frequencies with Radar Activity
In some regions, it is important to ensure that wireless access equipment does
not interfere with certain radar systems in the 5 GHz band. If radar is being
detected, the wireless access network should move automatically to a frequency
that does not interfere with the radar system.
The country dependent set of parameters includes also an indication whether
DFS (Dynamic Frequency Selection) should be used. The DFS algorithm is
designed to detect and avoid operation in channels with radar activity. If the
current sub-band does not support DFS, then the DFS parameters configuration
submenu is not available.
When DFS is enabled, the AU monitors the spectrum continuously, searching for
signals with a specific pattern indication radar activity. Upon detecting radar
activity, the AU immediately stops transmitting on this frequency and starts
looking for another radar-free frequency. The subset of viable frequencies is
configurable.
The AU maintains a continuously updated database of all applicable frequencies,
where each frequency is marked as Radar Free, Radar Detected or Adjacent to
Radar. The AU attempts to check a new frequency only if it is marked as Radar
Free. If a radar activity was detected on a certain frequency, it will be marked in
the database as a Radar Detected frequency. The AU will not attempt to check for
radar activity in frequencies marked as Radar Detected. A certain time after
detecting radar activity on a frequency, it will be removed from the list of Radar
Detected frequencies and will be marked as Radar Free. If radar activity was
detected on a certain frequency, adjacent channels should not be used as well,
according to the bandwidth. For instance, if the bandwidth is 20 MHz, then if
radar activity was detected in 5800 MHz, frequencies 5790 MHz and 5810 MHz
should not be used as well. These frequencies are marked in the database as
Adjacent to Radar, and will be treated the same as Radar Detected frequencies.
BreezeACCESS VL System Manual
132
Menus and Parameters
Before ceasing transmission on the frequency where radar signals had been
detected, the AU sends a special disassociation message to its associated SUs.
This message includes an indication whether the SUs should wait for this AU. If
the SUs should wait, the message includes also the waiting time. During this
time each SU searches for the AU in the defined frequencies subset. If the AU was
not found within the waiting time, or if a waiting request was not included in the
message, the SU starts searching for any AU, using the Best AU mechanism if
applicable.
Typically, operators prefer to preserve the original frequency planning and to
avoid moving to a new channel unless they are sure that there is a continuous
radar activity in the original channel. It should be noted that detection of radar
activity does not necessarily indicate a continuous radar activity in the channel.
A channel reuse algorithm enables returning to the original channel under
certain conditions that indicates low radar activity on the channel.
4.2.6.2.4
Frequency Definition Submenu in AU
The Frequency Definition submenu in AU includes the following parameters:
4.2.6.2.4.1 Sub-Band Select
This parameter is available only if the country code supports two or more SubBands. For information on how to view the Sub-Bands supported by the unit and
the supported parameters’ values and options, refer to section 4.2.2.4.
The range depends on the number of Sub-Bands supported by the country code.
The default selection is Sub-Band 1.
4.2.6.2.4.2 Frequency
The Frequency parameter defines the transmit/receive frequency when DFS is
not enabled. If DFS is enabled, it sets the initial operational frequency upon
starting the DFS mechanism for the first time.
The range depends on the selected Sub-Band.
The default is the lowest frequency in the Sub-Band.
NOTE 1 (Japan 4.9 GHz, 10 MHz Bandwidth):
In BreezeACCESS units operating in the 4.9 GHz Japan band (not B&B point-topoint) with a 10 MHz bandwidth, the following rules must be met for full
compliance with regulations:
1. When operating at 4945 MHz, the Transmit Power parameter in the AU

bandwidth, if you wish to include frequency channel 5265 MHz in the set of
frequencies to be used, then the Transmit Power parameter in the AU, and the
Maximum Tx Power parameter in the SUs, should not be set to a value above “25Antenna Gain”. If there is a need to use a higher value for these parameters, this
frequency should not be used.
NOTE 3 (FCC 5.3 GHZ, 20 MHz Bandwidth)
For full compliance with FCC regulations, the following requirements should be
followed in units using a 20 MHz bandwidth:
1. In units HW Revision B, if you wish to include frequency channel 5270 MHz
in the set of frequencies to be used, then the Transmit Power parameter in
the AU, and the Maximum Tx Power parameter in the SUs, should not be set
to a value above “17-Antenna Gain”. If there is a need to use a higher value
for these parameters, this frequency should not be used.
2. In units with HW Revision C, if you wish to include one or more of frequency
channels 5270, 5275 and 5330 MHz in the set of frequencies to be used,
then the Transmit Power parameter in the AU, and the Maximum Tx Power
parameter in the SUs, should not be set to a value above “20-Antenna Gain”.
If there is a need to use a higher value for these parameters, this frequency
should not be used.

Best AU Parameters (SU)
An SU that can communicate with more than one AU using the same ESSID may
become associated with the first AU it "finds", not necessarily the best choice in
terms of quality of communication. The same limitation also exists if only one AU
in the neighborhood has an ESSID identical to the one used by the SU, as it is
not always necessarily the best choice.
The topology of a fixed access network is constantly changing. Changes in base
station deployment and subscriber density can accumulate to create substantial
changes in SU performance. The quest for load sharing together with the desire to
create best throughput conditions for the SU created the need for the Best AU
feature, to enable an SU to connect to the best AU in its neighborhood.
When the Best AU feature is used, each of the AUs is given a quality mark based
on the level at which it is received by the SU. The SU scans for a configured
number of cycles, gathering information from all the AUs with which it can
communicate. At the end of the scanning period, the SU reaches a Best AU
decision according to the information gathered. The AU with the highest quality
mark is selected as the Best AU, and the SU will immediately try to associate with
it. The quality mark given to each AU depends on the level at which it is received
by the SU.
The Best AU selection mechanism can be overridden by defining a specific AU as
the preferred AU.
BreezeACCESS VL System Manual
138
Menus and Parameters
NOTE
Although the SU selects the Best AU based on long-term conditions prior to the decision time, it
may not always be connected to the instantaneous Best AU at any given time. Note also that the
decision is made only once during the scanning interval. The decision may not remain the optimal
one for ever. If there are significant changes in deployment of neighboring AUs and the SUs served
by them, overall performance may be improved if the applicable SUs are reset intentionally so as to
re-initiate the Best AU decision process.
The Best AU Parameters menu includes the following options:
4.2.6.2.6.1 Best AU Support
The Best AU Support option enables or disables the Best AU selection feature.
The default is Disable.
NOTE
If the Best AU feature is not used, the SU associates with the first AU it finds whose ESSID or
Operator ESSID is identical to its own ESSID.
4.2.6.2.6.2 Number Of Scanning Attempts
When the Best AU option is enabled, the SU gathers information on neighboring
AUs for approximately 2 seconds on each of the scanned frequencies. The
Number of Scanning Attempts parameter defines the number of times that the
process will be repeated for all relevant frequencies. A higher number may result
in a better decision at the cost of an increased scanning time during which the
SU is not operational.
Valid values: 1 - 255.
Default value: 4.
4.2.6.2.6.3 Preferred AU MAC Address
The Preferred AU MAC Address parameter defines a specific AU with which the
SU should associate. Gaining control of the SUs association is a powerful tool in
network management. The Preferred AU MAC Address parameter is intended for
applications where there is a need to dictate the preferred AU with which the SU
should associate. To prevent the SU from associating with the first viable AU it
finds, the Best AU Support mechanism should be enabled. Once the SU has
identified the preferred AU based on its MAC address, it will associate with it and
terminate the scanning process. If the preferred AU is not found, the SU will
associate with an AU according to the decision reached using the best AU
algorithm.
Valid values: A MAC address string.
The default value for the Preferred AU MAC Address is 00-00-00-00-00-00 (12
zeros), meaning that there is no preferred AU.

4.2.6.2.7
Scanning Mode (SU only)
The Scanning Mode parameter defines whether the SU will use Passive or Active
scanning when searching for an AU.
In passive scanning, the SU “listens” to the wireless medium for approximately
two seconds at each frequency, searching for beacons. The disassociation period,
which is the time from the moment the link was lost until the SU decides that it
should start searching for another AU, is approximately seven seconds.
In some situations when there is a high probability that SUs might need to roam
among different AUs, the use of active scanning enables to significantly reduce
BreezeACCESS VL System Manual
140
Menus and Parameters
the link establishment time. This is achieved by using shorter dwell periods,
transmitting a Probe Request at each frequency. This reduces the time spent at
each frequency as well as the disassociation period.
When DFS is supported by the Country Code being used by the SU, Scanning
Mode is forced to Passive.
The default selection is Passive.
4.2.6.2.8
Power Control Parameters
The Automatic Transmit Power Control (ATPC) algorithm simplifies the
installation process and ensures optimal performance while minimizing
interference to other units. This is achieved by automatically adjusting the power
level transmitted by each SU according to the actual level at which it is received
by the AU. To support proper operation of the system with optimal performance
and minimum interference between neighboring sectors, the ATPC algorithm
should be enabled in all units.
The algorithm is controlled by the AU that calculates for each received frame the
average SNR at which it receives transmissions from the specific SU. The average
calculation takes into account the previous calculated average, thus reducing the
effect of short temporary changes in link conditions. The weight of history (the
previous value) in the formula used for calculating the average SNR is determined
by a configurable parameter. In addition, the higher the time that has passed
since the last calculation, the lower the impact of history on the calculated
average. If the average SNR is not in the configured target range, the AU
transmits to the SU a power-up or a power-down message. The target is that each
SU will be received at an optimal level, or as high (or low) as possible if the
optimal range cannot be reached because of specific link conditions.
Each time that the SU tries to associate with the AU (following either a reset or
loss of synchronization), it will initiate transmissions using its Transmit Power
parameters. If after a certain time the SU does not succeed to synchronize with
the AU, it will start increasing the transmit power level.
In an AU the maximum supported transmit power is typically used to provide
maximum coverage. However, there may be a need to decrease the transmitted
power level in order to support relatively small cells and to minimize the
interference with the operation of neighboring cells, or for compliance with local
regulatory requirements.
In some cases the maximum transmit power of the SU should be limited to
ensure compliance with applicable regulations or for other reasons.
Different power levels may be used for different modulation levels by taking into
account possible HW limitations or regulatory restrictions.

4.2.6.2.8.1.1 Transmit Power
In the AU, the Transmit Power parameter defines the fixed transmit power level
and is not part of the ATPC algorithm.
In the SU, the Transmit Power parameter defines the fixed transmit power level
when the ATPC algorithm is disabled. If the ATPC Option is enabled, the value
configured for this parameter serves for setting the initial value to be used by the
ATPC algorithm after either power up or losing synchronization with the AU.
The minimum value for the Transmit Power Parameter is -10 dBm (the ATPC may
reduce the actual transmit power of the SU to lower values). The maximum value
of the Transmit Power Parameter depends on several unit properties and
parameters:
„ The HW revision of the unit
„ The Maximum Allowed Tx Power as defined for the applicable Sub-Band.
„ The Maximum EIRP as defined for the applicable Sub-Band, together with the
value of the Antenna Gain. In certain countries the Maximum EIRP of some

4.2.6.2.8.3.4 Minimum Interval Between ATPC Messages
The Minimum Interval Between ATPC Messages parameter sets the minimal time
between consecutive power-up/power-down messages to a specific SU. Setting a
low value for this parameter may lead to higher overhead and to an excessive rate
of power level changes at the SUs. High values for this parameter increase the

power-up/power-down message. If the distance between the value of the Current
Transmit Power and the desired range is smaller than the step size, the powerup/power-down message will include the specific step value required for this
condition.
Valid range: 1-20 (dB)
Default value: 5 (dB)
4.2.6.2.8.4 ATPC Parameters in SU
4.2.6.2.8.4.1 ATPC Option
The ATPC Option enables or disables the Automatic Transmit Power Control
(ATPC) algorithm. The parameter takes effect immediately. However, when
changed from Enable to Disable, the transmit power level will remain at the last
Current Transmit Power determined by the ATPC algorithm before it was
disabled. It will change to the value configured for the Initial Transmit Power
parameter only after the next reset or following loss of synchronization.
The default is Enable.
NOTE
The accuracy of the Transmit Power level is typically +/- 1 dB. However, at levels that are 15 dB or
more below the maximum supported by the hardware, the accuracy is +/- 3 dB (for information on
hardware limitations refer to the Country Codes document). At these levels the use of ATPC may
cause significant fluctuations in the power level of the transmitted signal. When operating at such
low levels, it is recommended to disable the ATPC Option and to set the Transmit Power parameter
to the average Tx Power level before the ATPC was disabled.

If the selected option is Ethernet Status Control, then:
„ If the Ethernet link is down, the AU transmitter will be switched to Off
„ If the Ethernet link is up, the AU transmitter will be switched to On.
This feature can be used during maintenance or testing to avoid transmissions
using undesired parameters.
The parameter is available only when managing the unit from its Ethernet port.
The default is On.
4.2.6.2.9
Antenna Gain
The Antenna Gain parameter enables to define the net gain of a detached
antenna. The configured gain should take into account the attenuation of the
cable connecting the antenna to the unit. The Antenna Gain is important
especially in countries where there is a limit on the EIRP allowed for the unit; the
maximum allowed value for the Transmit Power parameters cannot exceed the
value of (EIRP - Antenna Gain), where the EIRP is defined in the selected SubBand.
In certain units with an integral antenna the Antenna Gain is not available as a
configurable parameter. However, it is available as a read-only parameter in the
applicable “Show” menus.
The lower limit for the Antenna Gain parameter is 0 (dBi). The upper limit for the
Antenna Gain is Regulation Max EIRP + 10 in dBi (since the minimum Tx Power
is -10dBm), up to a maximum of 50 (dBi). If Regulation Max EIRP is No Limit, the
upper limit is 50 (dBi). A value of “Don’t Care” means that the actual value is not
important. A value of “Not Set Yet” means that the unit will not transmit until the
actual value (in the range 0 to 50) is configured. The unit can be configured to
“Don’t Care” or “Not Set Yet” only in factory (when upgraded to SW version 2.0
from a lower version it will be set automatically to one of these options). Once a
value is configured, it is not possible to reconfigure the unit to either “Don’t Care”
or “Not Set Yet”.
The default value depends on unit type. In SUs with integral antenna it is set to
21 (read only). The default value for AUs that are supplied with a detached
antenna is in accordance with the antenna’s gain. In units supplied without an
antenna the default is typically “Not Set Yet”.

4.2.6.2.10 Cell Distance Parameters (AU only)
The higher the distance of an SU from the AU that is serving it, the higher the
time it takes for messages sent by one of them to reach the other. To ensure
appropriate services to all SUs regardless of their distance from the AU while
maintaining a high overall performance level, two parameters should be adapted
to the distances of SUs from the serving AU:
„ The time that a unit waits for a response message before retransmission (ACK
timeout) should take into account the round trip propagation delay between
the AU and the SU (The one-way propagation delay at 5 GHz is 3.3
microseconds per km/5 microseconds per mile.). The higher the distance from
the AU of the SU served by it, the higher the ACK timeout should be.
The ACK timeout in microseconds is: 20+Distance (km)*2*3.3 or
20+Distance (miles)*2*5.
„ To ensure fairness in the contention back-off algorithm between SUs located
at different distances from the AU, the size of the time slot should also take
into account the one-way propagation delay. The size of the time slot of all
units in the cell should be proportional to the distance from the AU of the
farthest SU served by it.
The Cell Distance Mode parameter in the AU defines the method of computing
distances. When set to Manual, the Maximum Cell Distance parameter should be
configured with the estimated distance of the farthest SU served by the AU. When
set to Automatic, the AU uses a special algorithm to estimate its distance from
each of the SUs it serves, determine which SU is located the farthest and use the
estimated distance of the farthest SU as the maximum cell distance. The value of
the maximum cell distance parameter (either computed or configured manually)
is transmitted in the beacon messages to all SUs served by the AU, and is used
by all units to calculate the size of the time slot, that must be the same for all
units in the same sector. When the Per SU Distance Learning option is enabled,
the AU uses the re-association message to send to each SU its estimated distance
from the AU. The per-SU distance is used to calculate the ACK timeout to be used
by the SU. When the Per SU Distance Learning option is disabled (or if it cannot
be used because the SU uses a previous SW version that does not support this
feature), the SU will use the maximum cell distance to calculate the ACK timeout.
The AU always uses the maximum cell distance to calculate the ACK timeout.
It should be noted that if the size of the time slot used by all units is adapted to
the distance of the farthest unit, then no unit will have an advantage when
competing for services. However, this reduces the overall achievable throughput
of the cell. In certain situations, the operator may decide to improve the overall
throughput by reducing the slot size below the value required for full fairness
(using the Fairness Factor parameter). This means that when there is competition
Operation and Administration
147
Chapter 4 - Operation and Administration
for bandwidth, the back-off algorithm will give an advantage to SUs that are
located closer to the AU.
The Cell Distance Parameters menu includes the following parameters:
4.2.6.2.10.1 Cell Distance Mode
The Cell Distance Mode option defines whether the maximum distance of the AU
from any of the SUs it serves will be determined manually (using the Maximum
Cell Distance parameter) or automatically. In addition, the Per SU Distance
Learning feature is supported only when the Cell Distance Mode is set to
Automatic.
The Options are Automatic or Manual.
The default is Automatic.
4.2.6.2.10.2 Maximum Cell Distance
The Maximum Cell Distance parameter allows configuring the maximum distance
when the Cell Distance Mode option is Manual.
The range is 0 to 54 (Km). The value of 0 has a special meaning for No
Compensation: Acknowledge Time Out is set to a value representing the
maximum distance of 54 km. The time slot size is set to its minimal value of 9
microseconds.
The default is 0 (No Compensation).
4.2.6.2.10.3 Fairness Factor
The Fairness Factor enables to define the level of fairness in providing services to
different SUs. When set to 100%, all SUs have the same probability of getting
services when competing for bandwidth. If set to X%, then SUs located up to X%
of the maximum distance from the AU will have an advantage in getting services
over SUs located farther than this distance.
The range is 0 to 100 (%)
The default is 100 (%).
4.2.6.2.10.4 Per SU Distance Learning
The Per SU Distance Learning option defines the mode in which SUs calculate the
ACK timeout: based on the maximum cell distance or on the actual distance from
the AU.
When this feature is disabled, all SUs in the cell use for the calculation of the
ACK timeout the maximum cell distance; when enabled, each SU uses instead its
actual distance from the AU.
The options are Disable or Enable.
The default is Disable.

4.2.6.2.11 Arbitration Inter-Frame Spacing (AIFS)
The time interval between two consecutive transmissions of frames is called InterFrame Spacing (IFS). This is the time during which the unit determines whether
the medium is idle using the carrier sense mechanism. The IFS depends on the
type of the next frame to be transmitted, as follows:
„ SIFS (Short Inter-Frame Spacing) is used for certain frames that should be
transmitted immediately, such as ACK and CTS frames. The value of SIFS is
16 microseconds.
„ DIFS (Distributed coordination function Inter-Frame Spacing) is typically
used for other frame types when the medium is free. If the unit decides that
the medium is not free, it will defer transmission by DIFS plus a number of
time slots as determined by the Contention Window back-off algorithm (see
section 0) after reaching a decision that the medium has become free.
DIFS equal SIFS plus AIFS, where AIFS can be configured to a value from 1 to 50
time slots. A unit with a lower AIFS has an advantage over units with a higher
AIFS, since it has a better chance to gain access to limited wireless link
resources. Typically, AIFS should be configured to two time slots. A value of 1
should only be used in one of the two units in a point-to-point link, where in the
other unit the AIFS remains configured to two time slots. This ensures that the
unit with AIFS configured to one has an advantage over the other unit, provided
that the Minimum Contention Window (section 0) parameter in both units is
configured to 0 to disable the contention window back-off algorithm.
NOTE
The AIFS parameter is not applicable when the Wireless Link Prioritization Option is enabled.
The available range is from 1 to 50 (time slots).
The default is 2 time slots.
CAUTION
An AIFS value of 1 should only be used in point-to-point applications (when the Wireless Link
Prioritization Option is enabled). Otherwise the default value of 2 must always be used. In a pointto-point link, only one unit should be configured to an AIFS value of 1. When both units need to
transmit, the unit with an AIFS value of 1 will have an advantage over the unit with AIFS of 2. In this
case, the Minimum Contention Window parameter in both units must be configured to 0 to disable
the contention window back-off algorithm.

guaranteeing the required quality of service to customers.
Available values for AU-BS and AU-SA range from 0 to 512. For AUS-BS and
AUS-SA the range is from 0 to 8.
Default value for AU-BS and AU-SA is 512. For AUS-BS and AUS-SA the default

be set to a value higher than 124.
The Maximum Number of Associations Limit (512 when Data Encryption is disabled, 124 when
Data Encryption is enabled) is indicated in the Show Air Interface Parameters display.
NOTE
There is no aging time for SUs. An SU is only removed from the list of associated SUs under the
following conditions:
„ The SU failed to respond to 100 consecutive data frames transmitted by the AU and is
considered to have "aged out".
„ During the last 6 minutes (or more) the SU did not transmit any data frame, and failed to
respond to certain frames that typically are transmitted by the AU every 10 seconds. Since the
sampling interval for this state is about 10 minutes, it means that the decision to remove the SU
from the Associations Database will take place between 6 to 16 minutes from the time the SU
ceased sending data or responding to these “keep-alive” frames (for AUS the sampling interval
is 1 minute, meaning decision time of 6 to 7 minutes).
Therefore, the database of associated SUs may include units no longer associated with the AU. If
the number of associated SUs has reached the value of the Maximum Number of Associations
parameter, the selected AU cannot serve additional SUs. To view the current number of associated
SUs, use the Display Association Info option in the MAC Address Database menu. To delete
inactive SUs from the database you must either disassociate them (see 4.2.6.2.16) or reset the AU.

The Wireless Link Trap Threshold is in percentage of retransmissions, and the
allowed range is from 1 to 100 (%).

4.2.6.2.15 Lost Beacons Transmission Watchdog Threshold (AU only)
When it is unable to send beacon frames for a predetermined period of time, such
as in the case of interferences, the AU resets itself. The Lost Beacons
Transmission Threshold parameter represents the number of consecutive lost
beacons after which the unit will reset itself.
The range for this parameter is 100 – 1000 or 0. When the parameter is set to 0,
this feature is disabled, i.e. internal refresh will never be performed.
The default value is 218.
4.2.6.2.16 Disassociate (AU only)
The Disassociate feature enables disassociating all SUs associated with the AU or
a selected SU. This feature is useful during configuration changes, enabling to

4.2.6.2.17 Noise Immunity Control
Noise Immunity Control parameters are available only in units with HW Revision
C and higher, except to the Pulse Detection Sensitivity parameter that is available
also in units with HW Revision B.
The Adaptive Noise Immunity (ANI) mechanism is designed to reduce the wireless
physical layer errors and by that enhance the processing power of the unit,
delivering higher packet processing efficiency.
This ANI mechanism is triggered by the rate of detected Physical Errors and it is
modifying different thresholds affecting the immunity to specific interference
types.
This feature, active by default, exists in all units with HW revision C and higher
running SW version 3.0 and higher. Starting in SW version 4.0, the processing
power of the system has been increased dramatically. When using version 4.0 the
units are capable to process more packets per seconds, including physical error
packets. As a result, the ANI mechanism (triggered by the number of received
error packets) may not function properly in certain scenarios, resulting in link
performances that are far below the expectations. The option of manually
controlling the various parameters used by the ANI mechanism enables to
Operation and Administration
153
Chapter 4 - Operation and Administration
achieve optimal performance in certain deployments where the automatic ANI
mechanism may not function properly.
It is strongly recommended to consult with Alvarion experts before switching to
manual mode and modifying any of the parameters.
The general rules for using the Noise Immunity Control parameters are:
In the SU, if performance (Modulation Level) is lower than expected based on the
SNR, try switching to Manual mode without changing any of the parameters.
CAUTION
Do not change any of the SU’s Noise Immunity Control parameters (except the Noise Immunity
State Control) from remote, as it may result in loss of connectivity to the unit.
In the AU, try switching to Manual mode if overall throughput is too low or if SUs
are lost although communication conditions are sufficient for good connectivity.
In many deployments the transition to Manual mode is sufficient. If not, you may
try changing the Noise Immunity Level and/or Spur Immunity Level parameters.
The target is to reduce the amount of Phy Error rate reported by the unit (see
Total Rx events on page 117). To ensure that sensitivity is not reduced too much
and SUs are not lost, verify that the Age (see Display Association Info on page
121) of all SUs is below 20 seconds.
Do not activate the OFDM Weak Signal parameter if the SNR is below 36 dB.
Under normal conditions, the OFDM Weak Signal should never be activated in
the AU, since the SNR of all SUs will be below 36 dB when ATPC is enabled.
The Noise Immunity Control submenu includes the following options:
4.2.6.2.17.1 Noise Immunity State Control
The Noise Immunity State Control defines the activation mode of the Adaptive
Noise Immunity mechanism: Automatic or Manual. The following parameters of
the Noise Immunity Control mechanism are applicable only for Manual mode.
The default is Automatic.
4.2.6.2.17.2 Noise Immunity Level
The Noise Immunity Level parameter sets the threshold for immunity against
broadband interfering signals. A higher value may reduce the number of errors at
the expense of reduced sensitivity.
The range is from 0 to 4. In the current version only 0 and 4 should be used.
The default is 0.
4.2.6.2.17.3 Spur Immunity Level
The Spur Immunity Level parameter sets the threshold for immunity against
narrow band interfering signals such as spurious from signals at other
BreezeACCESS VL System Manual
154
Menus and Parameters
frequencies. A higher value may reduce the number of errors at the expense of
reduced sensitivity.
The range is from 0 to 7.
The default is 0.
4.2.6.2.17.4 OFDM Weak Signal
The OFDM Week Signal parameter sets the threshold for immunity against
interfering OFDM signals.
The available options are 0 or 1. A value of 1 means that the unit will immediately
reject OFDM packets with a relatively low SNR.
The default is 0.
4.2.6.2.17.5 Pulse Detection Sensitivity
The Pulse Detection Sensitivity parameter affects the Phy error count: If it is set
to Low, than all Phy errors will be reported as regular Phy errors, regardless of
the signal level. If it is set to High, all Phy errors with levels bellow a certain
threshold (not accessible to the user) will be reported as regular Phy errors, while
those with levels higher than the threshold will be reported as detected radar
pulses.
When DFS (radar detection) is used or during a Spectrum Analysis test, the Pulse
Detection Sensitivity is set internally to High (regardless of the configured value).
The default is Low.

Select this option to view the current values of the Noise Immunity Control
parameters, and some additional parameters of the ANI mechanism.
4.2.6.2.18 Noise Floor Calculation Parameters
The Noise Floor calculation mechanism incorporated in the units is used for
estimating the level of the noise floor. This value is used for estimating SNR
values and for decisions on existence of signals in the channel. In some cases,
especially when a very strong signal exists in neighboring channels, the noise
floor calculated by the built-in mechanism may be significantly below the actual
noise floor level.
Typically, the expected noise floor level is:
„ 5 MHz bandwidth: -102 (dBm)
„ 10 MHz bandwidth: -99 (dBm)
„ 20 MHz bandwidth: -96 (dBm)
Operation and Administration
155
Chapter 4 - Operation and Administration
The default calculation mode is Fully Automatic, using only the built-in
mechanism. If you experience problems in the wireless link such as excessively
long association process or very low throughput, it may be caused by errors in
noise floor calculation. In this case, it is recommended to perform a Spectrum
Analysis (see section 4.2.6.2.14 on page 150) and view the Average Noise Floor
values. If the calculated Noise Floor is lower by more than 5 dB from the expected
value, it is recommended to change the calculation mode to Automatic with
Minimum Value, using the expected value as the minimum (Forced Value).
Note that if the SNR of received signals is very low (typically below 10 dB), it is
recommended to maintain the default calculation mode (Fully Automatic).
Changing the calculation mode to Automatic with Minimum Value may result in
loss of connectivity with units for which the calculated SNR before the change
was relatively low.
The Noise Floor Calculation Parameters submenu includes the following options:
4.2.6.2.18.1 Calculation Mode
The Calculation Mode defines the method used for calculation the Noise Floor
value to be used by the device for estimating the quality of received signals. The
available options are:
„ Fully Automatic: According to the built-in noise floor calculation
mechanism.
„ Forced: The Noise Floor value is set manually to the value configured for the
Forced Value parameter (see below). Typically this mode should be used only
for special testing purposes.
„ Automatic with Minimum Value: If the calculated Noise Floor using the
built-in mechanism is higher than the value configured for the Forced Value
parameter, the calculated value will be used. Otherwise, the Forced Value will
be used.
The default option is Fully Automatic.
4.2.6.2.18.2 Forced Value
The Forced Value parameter enables configuring the Noise Floor to be used if the
selected Calculation Mode is Forced. This is also the minimum value to be used if
the selected Calculation Mode is Automatic with Minimum Value.
If you decided to change the calculation mode to Automatic with Minimum Value
and you still experience problems in the link (long association time, exceptionally
low throughput), try to improve it by increasing the configured Forced Value.
The available range is from -107 to -55 (dBm)

4.2.6.2.19 Interference Mitigation (VL 900 only)
The Interference Mitigation functionality allows users to configure the unit’s
operating channel and noise floor level in order to meet particular requirements
regarding throughput and distance. The unit will scan and analyse the 900 MHz
spectrum, and, depending on the detected noise levels, it will choose an optimal
operating channel and noise floor level.
There are two types of optimization mechanisms available. The unit can either
find settings that will ensure the best range for a given throughput or settings
that will ensure the best throughput for a given range. Based on the sector’s
topography, the unit estimates a theoretical link budget, and matches it against
the noise levels detected during the scan to identify the settings that best meet
the user’s requirements.
The Interference Mitigation offers a quick and efficient mechanism for setting up
access units in the noisy environment of the 900 MHz band, when the operator
doesn’t have the time or the expertise required for a full spectrum analysis and
channel optimization. For optimal results however, a thorough radio planning
performed by a radio specialist is always recommended.
CAUTION
Upon activating the Interference Mitigation, the unit will automatically reset. The unit will enter
passive scanning mode for a definite period of time, during which information will be gathered.
During the information-gathering period, the unit will not receive nor transmit data. Also, it will not
be able to synchronize/associate, meaning that it cannot be managed via the wireless link. At the
end of the period, the unit will reset automatically regaining normal operability upon start up.

VLAN includes stations that can communicate with each other, but cannot
communicate with stations belonging to different VLANs. The VLAN feature also
provides the ability to set traffic priorities for transmission of certain frames. The
information related to the VLAN is included in the VLAN Tag Header, which is
inserted in each frame between the MAC header and the data. VLAN
implementation in BreezeACCESS VL units supports frame routing by port
information, whereby each port is connected to only one VLAN.
The system also supports the 802.1 QinQ standard, which defines the way to
have 2 VLAN tags (double-tagged frames). This procedure allows an additional
VLAN tag, called Service Provider VLAN tag, to be inserted into an existing
IEEE 802.1Q tagged Ethernet frame. This is a solution to transport multiple
customers’ VLANs across the service provider’s network without interfering with
each other.

„ Only single-tagged management frames with a matching VLAN ID, or doubletagged management frames with a matching Service Provider VLAN ID
received on either the Ethernet or wireless link ports are forwarded to the
unit.
„ A VLAN Management Tag is inserted in all management frames generated by
the unit before transmission on either the Ethernet or wireless link port. The
tag includes the values of the VLAN ID-Management and the VLAN PriorityManagement parameters.
If the VLAN ID-Management is 65535 (No VLAN):
„ For Access, Trunk and Hybrid links: Only untagged management frames
received on either the Ethernet or wireless link ports are forwarded to the
unit.
„ An AU operating in Service Provider link mode with VLAN ID – Management =
65535 cannot be managed from either the Ethernet or wireless ports.
„ An SU operating in Service Provider link mode with VLAN ID – Management =
65535 will accept untagged management frames from the Ethernet port. From
the wireless port it will accept only tagged frames with a VLAN ID tag that
matches the defined Service Provider VLAN ID.
„ Management frames generated by the unit are not tagged.

4.2.6.4.1.3.2 Trunk Link
Trunk Link transfers only tagged frames, as all devices connected to the unit are
VLAN aware. Only tagged data frames received on the Ethernet or wireless link
ports are forwarded.
CAUTION
It is not recommended that you configure a unit as a Trunk Link with the VLAN ID-Management
parameter set at 65535, as it does not forward any 'NO VLAN' management frames to its other
port, making it impossible to manage devices connected behind the unit that are also configured
with 'NO VLAN'.
If the VLAN Forwarding option is enabled, a data frame received with a VLAN ID
that is not a member of the unit's VLAN Forwarding List is discarded.
NOTE
If the VLAN Forwarding option is enabled, be sure to include the VLAN ID-Management value of
all units that should be managed via the wireless port of the unit, in the Forwarding List.
If the VLAN Relaying option is enabled in an AU, a data frame relayed with a
VLAN ID that is not a member of the unit's VLAN Relaying List is discarded.
NOTE
If the VLAN Relaying option is enabled and you manage your devices from behind an SU unit, be
sure to include the VLAN ID-Management value of all units to be managed when relaying via the
wireless port of the AU unit, in the Relaying List. If the VLAN Forwarding option is also enabled in
the AU, these VLAN IDs should also be included in the Forwarding List.

transmitted per second, in order to prevent the potential flooding of the wireless
medium by certain ARP attacks.
In SUs, the limiter is placed after the Ethernet Broadcast Filters. For this reason,
the limiter will receive only the packets that pass through these filters. If the
Ethernet filters of the SU are disabled, the limiter will be applied to all relevant
packets received.
When the Ethernet Broadcast/Multicast Limiter is enabled and the specified limit
is reached, the unit will send a trap. The trap will be sent periodically till the
number of broadcast/multicast packets will be less than the maximum. The trap
will inform the user how many packets were discarded in the last period.

Roaming Option (SU only)
The Roaming Option defines the roaming support of the unit. When roaming is
not expected, it is preferable to set this parameter to Disable. This will cause the
unit to start scanning for another AU after losing connectivity with the current
AU only after 7 seconds during which no beacons were received from the current
AU. This will prevent scanning for another AU in cases where no beacons were
received due to a short temporary problem.
When set to Enable, the SU will wait only one second before it starts scanning for
another AU. In addition, when the Roaming Option is enabled, the SU will send
Roaming SNAP messages upon associating with a new AU. This enables fast
distribution of the new location for all clients that are behind the SU. In this case,
the SU will send multicast SNAP messages via the wireless link each time it
associates with a new AU, except for the first association after reset. The SU will
send one SNAP message for each client learned on its Ethernet port, based on its
bridging table. In the SNAP message the clients’ MAC address is used as the
source address. The AU that receives this SNAP message learns from it the new
location of the clients. It forwards the SNAP to other AUs and Layer-2 networking
equipment via its Ethernet port, to facilitate uninterrupted connectivity and
correct routing of transmissions to these clients. The new AU as well as the
previous AU with which the SU was associated, will forward the SNAP messages
to all other SUs associated with them.

RTS Threshold
The RTS Threshold parameter defines the minimum frame size that requires an
RTS/CTS (Request To Send/Clear To Send) handshake. Frames whose size is
smaller than the RTS Threshold value are transmitted directly to the wireless link
without being preceded with RTS frames. Setting this parameter to a value larger
than the maximum frame size eliminates the RTS/CTS handshake for frames
transmitted by this unit.
The available values range from 20 to 4092 bytes for units with HW revision C or
higher, and 20 to 2200 for units with HW revision A or B.
The default value for SUs is 60 bytes.
For AUs with HW revision C or higher, the default is 4092, and for AUs with HW
revision A or B the default is 2200. It is recommended that these values be used
to ensure that RTS/CTS is never used in the AU. Minimum Contention Window
Operation and Administration
183
Chapter 4 - Operation and Administration
The Minimum Contention Window parameter determines the time that a unit
waits from the time it has concluded that there are no detectable transmissions
by other units until it attempts to transmit. The BreezeACCESS VL system uses a
special mechanism based on detecting the presence of a carrier signal and
analyzing the information contained in the transmissions of the AU to estimate
the activity of other SUs served by the AU. The target is to minimize collisions in
the wireless medium resulting from attempts of more than one unit to transmit at
the same time.
The system uses an exponential Back-off algorithm to resolve contention between
several units that want to access the wireless medium. The method requires each
station to choose a random number N between 0 and a given number C each time
it wants to access the medium. The unit will attempt to access the medium only
after a time equal to DIFS (for more details refer to section 4.2.6.2.11) plus N time
slots, always checking if a different unit has accessed the medium before. Each
time the unit tries to transmit and a collision occurs; the maximum number C
used for the random number selection will be increased to the next available
value. The available values are 7, 15, 31, 63, 127, 255, 511 and 1023.
The Minimum Contention Window parameter is the first maximum number C
used in the back-off algorithm. The higher the number of SUs served by the same
AU, the higher the Minimum Contention Window for each SU should be. In
addition, when the Wireless Link Prioritization Option is enabled, the Minimum
and Maximum Contention Window parameters can be configured to provide
certain units with an advantage over other units.
The available values are 0, 7, 15, 31, 63, 127, 255, 511 and 1023. A value of 0
means that the contention window algorithm is not used and that the unit will
attempt to access the medium immediately after a time equal to DIFS.
The default value is 15.
CAUTION
A value of 0 disables the contention window back-off algorithm. It should only be used in point-topoint applications. For more details on configuring units in a point-to-point link refer to section
4.2.6.2.11.
4.2.6.5.2
Maximum Contention Window
The Maximum Contention Window parameter defines the upper limit for the

4.2.6.5.3
Multicast Modulation Level (AU only)
The Multicast Modulation Level parameter defines the modulation level used for
transmitting multicast and broadcast data frames. Multicast and broadcast
transmissions are not acknowledged; therefore if a multicast or broadcast
transmission is not properly received there is no possibility of retransmitting. It is
recommended that you set a lower modulation level for broadcast and multicast
frame transmissions to increase the probability that they are received without
errors.
The Multicast Modulation Level parameter is applicable only to data frames.
Beacons and other wireless management and control frames are always
transmitted at the lowest modulation level according to the Sub-Band.
The minimum and maximum values for the Multicast Modulation Level are
defined by the Sub-Band in use. For information on how to view the Sub-Bands
supported by the unit and the supported parameters’ values and options, refer to
section 4.2.2.4. Currently, all Sub Bands support the entire range of modulation
levels, from 1 to 8. However, the highest modulation level supported by units with
HW revision A is modulation level 7.
The default value is the lowest supported modulation level (modulation level 1).
4.2.6.5.4
Maximum Modulation Level
When the Adaptive Modulation Algorithm (see section 4.2.6.5.8) is enabled, it
changes the modulation level dynamically according to link conditions. The
purpose is to increase the probability of using the maximum possible modulation
level at any given moment. Although the algorithm will avoid using modulation
levels that are too high for the prevailing link conditions, it might be better under
certain conditions to limit the use of higher modulation levels. If the link quality
is not sufficient, it is recommended that the maximum modulation level be
decreased, as higher modulation levels increase the error rate. In such
conditions, a higher Maximum Modulation Level increases the number of
retransmissions before the modulation level is being reduced by the Adaptive
Modulation Algorithm. A high number of retransmissions reduces the overall
throughput of the applicable SU as well as all other SUs associated with the same
AU.
The link quality can be estimated based on the SNR measurement of the SU at
the AU, which can be viewed in the MAC Address Database option in the Site
Survey menu. If the measured SNR is less than a certain threshold, it is
recommended that the maximum modulation level of the SU be decreased in
accordance with Table 4-12, using the values of typical sensitivity. It is
recommended to add a 2 dB safety margin to compensate for possible
measurement inaccuracy or variance in the link quality.
Operation and Administration

Chapter 4 - Operation and Administration
NOTE
The SNR measurement at the AU is accurate only when receiving transmissions from the
applicable SU. If necessary, use the Ping Test utility in the Site Survey menu to verify data
transmission.
When the Adaptive Modulation Algorithm is disabled, this parameter will serve to
determine Fixed Modulation Level used for transmissions.
The minimum and maximum values for the Maximum Modulation Level are
defined by the Sub-Band in use. For information on how to view the Sub-Bands
supported by the unit and the supported parameters’ values and options, refer to
section 4.2.2.4. Currently, all Sub Bands support the entire range of modulation
levels, from 1 to 8. However, the highest modulation level supported by units with
HW revision A is modulation level 7.
VL 900 SUs with HW revision F use a default maximum modulation level of 5. For
the rest of the units, the default is the highest supported modulation level (8 for
all units with HW revision B or higher, 7 for units with HW revision A).

Average SNR Memory Factor
The Average SNR Memory Factor defines the weight of history (value of last
calculated average SNR) in the formula used for calculating the current average
SNR for received data frames. This average SNR is used by the ATPC algorithm in
the AU and is also included in the Adaptive Modulation Algorithm information
messages transmitted by the AU and the SU. The higher the value of this
parameter, the higher is the weight of history in the formula.
BreezeACCESS VL System Manual

Available values: -1 to 32. -1 is for no weight for history, meaning that average
SNR equals the last measured SNR.
Default value: 5
4.2.6.5.6
Number of HW Retries
The Number of HW Retries parameter defines the maximum number of times that
an unacknowledged packet is retransmitted. When the Adaptive Modulation
Algorithm is disabled, a frame will be dropped when the number of unsuccessful
retransmissions reaches this value. For details on the effect of this parameter
when the Adaptive Modulation Algorithm is enabled, refer to section 4.2.6.5.8.
NOTE
The Number of HW Retries parameter is not applicable when the Wireless Link Prioritization Option
is enabled.
The available values range is from 1 to 14.
The default value is 10.
4.2.6.5.7
Burst Mode
Burst mode provides an increased throughput by reducing the overhead
associated with transmissions in the wireless medium. In a burst transmission
the inter-frame spacing is reduced and unicast data frames are transmitted
without any contention period (burst mode is not activated on
broadcasts/multicasts).
The Burst Mode is available only if Burst Mode is supported by the Sub-Band in
use. For information on how to view the Sub-Bands supported by the unit and
the supported parameters’ values and options, refer to section 4.2.2.4.
In AUs with HW Revision B or lower, Burst Mode cannot be activated when DFS
is used. In AUs with HW Revision B or lower, the Burst Mode option will be
“blocked” upon trying to enable Burst Mode when DFS is enabled. This limitation
does not apply to AUs with HW Revision C.
In SUs and AUs with HW Revision B or lower, Burst Mode cannot be activated
when using WEP for data encryption. In units with HW Revision B or lower, the
Burst Mode option will be “blocked” upon trying to enable it when using WEP for
data encryption. This limitation does not apply to units with HW Revision C.
NOTE
The Burst Mode parameters are not applicable when the Wireless Link Prioritization Option is
enabled.

The default is Enable.
4.2.6.5.7.2 Burst Mode Time Interval
The Burst Mode Time Interval defines the burst size, which is the time in which
data frames are sent immediately without contending for the wireless medium.
The range is 1 to the value of the Maximum Burst Duration defined for the SubBand.
The default is 5 milliseconds or the value of Maximum Burst Duration defined for
the Sub-Band (the lower of the two values).
4.2.6.5.8
Adaptive Modulation
The Adaptive Modulation algorithm enables adapting the modulation level of
transmitted data to the prevailing conditions of the applicable radio link. The
algorithm provides Access Units with simultaneous, adaptive support for multiple
Subscriber Units at different modulation levels, as transmission’s modulation
level decisions are made separately for each associated SU.
Link quality fluctuates due to various environmental conditions. Dynamically
switching between the possible modulation levels increases the probability of
using the maximum modulation level suitable for the current radio link quality at
any given moment.
When enabled, the Adaptive Modulation algorithm, constantly evaluates the
acievable throughput for a particular modulation by counting the number of
packets that are successfully transmitted and the packets that are not received
and that need to be retransmitted. Based on these statistics, and on each
modulation’s specific data rate, it will calculate the real throughput that the unit
can support in the current conditions for a particular modulation.
When choosing between modulations, up to a limit, a small number of
retransmissions on a higher modulation is compensated by the overall better
performance ensured by that modulation. When a critical retransmissions
percentage is reached however, it is necessary to decrease the modulation to
achieve better throughputs as shown in Table 4-13.

When the above mentioned retransmission percentages are reached, the Adaptive
Modulation algorithm will lower the modulation. If the connection is stable on a
particular modulation, the unit will periodically check whether it can further
increase the modulation (except on modulation 8), by sending a number of test
packets using this higher modulation and checking the retransmission rate.
The user can configure a Packet Thershold to Test Up Rate parameter to define
the number of successfully transmitted frames after which the unit will test the
higher modulation. The number of frames used for this test can also be
configured by the user via the Packet No On Upper Rate parameter.
4.2.6.5.8.1 Adaptive Modulation Option
The Adaptive Modulation Option enables or disables the Adaptive Modulation
decision algorithm. When enabled, the algorithm supports decrease/increase of
transmission’s modulation levels between the lowest possible level to the value
configured for the Maximum Modulation Level parameter. If the Maximum
Modulation Level is set at the lowest possible level, the Adaptive Modulation
algorithm has no effect.
The default selection is Enable.

4.2.6.5.9
Concatenation Parameters
The Concatenation mechanism enables bundling several data frames into a single
frame for transmission to the wireless link. This feature improves throughput and
reduces the overhead in the wireless medium, by requiring only one CRC for each
concatenated frame, one RTS/CTS cycle if applicable, and a single waiting period
according to the contention window mechanism before transmission. When
concatenation is enabled, data packets in the queue of the internal bridge can be
accumulated before the concatenated frame is transmitted to the wireless
medium. Data frames can be accumulated up to a maximum frame size of 2200
bytes for units with HW revision A or B, or 4032 bytes for units with HW revision
C or higher. In the AU, the concatenation process is performed separately for
each destination SU.
NOTE
Using the Link Capability exchange mechanism, each unit learns the HW Revision and the SW
Version of the unit(s) associated with it. A concatenated frame with a length exceeding 2200 bytes
may be generated and transmitted only if both the source and destination units have HW Revision
C or higher. If either the source or destination unit uses SW Version 3.0 or 3.1, then the maximum
size of the concatenated frame is 3400 bytes, and the maximum number of data frames that can be
bundled into a concatenated frame is 2 for units with SW version 3.0 and 8 for units with SW
version 3.1.
A frame is a candidate for bundling into a concatenated frame if all the following
conditions are met:
„ The frame is a data frame
„ The destination is an entity behind the destination AU/SU.
„ The destination AU/SU can support the feature (uses SW version 3.0 or
higher).
BreezeACCESS VL System Manual
190
Menus and Parameters
When a frame is identified as an eligible candidate for concatenation, it is marked
accordingly and will be processed according to the following:
„ If there is no concatenated frame designated to the same destination unit in
the queue:
‘ If the hardware queue is empty – the frame is transmitted immediately.
‘ Otherwise (the queue is not empty) – the frame is inserted to the queue as
a concatenated frame.
„ If a concatenated frame designated to the same destination unit exists in the
queue:
‘ If the combined size of both frames is above the maximum allowed
concatenated frame size – both frames are transmitted as two separate
frames.
‘ Otherwise (the combined frames size is below the maximum size) – the
new frame is added to the concatenated frame. If the number of data
frames in the concatenated frame has reached the maximum allowed
(applicable only if the destination unit uses SW version 3.0 or 3.1) – the
concatenated frame will be transmitted to the wireless medium. Otherwise
– the concatenated frame remains in the queue (until the hardware queue
becomes free).
NOTE
When a frame is marked as a candidate for concatenation, it will be transmitted as a concatenated
frame. If it is not bundled with another data frame before transmission, it will be a concatenated
frame with a single data frame (Concatenated Frame Single). If it is bundled with two or more data
frames, it will be a concatenated frame with either double data frames (Concatenated Frame
Double) or more data frames (Concatenated Frame More).

MIR and CIR Parameters
The CIR (Committed Information Rate) specifies the minimum data rate
guaranteed to the relevant subscriber. The MIR (Maximum Information Rate)
value specifies the maximum data rate available for burst transmissions,
provided such bandwidth is available.
Operation and Administration
193
Chapter 4 - Operation and Administration
Under normal conditions, the actual Information Rate (IR) is between the
applicable CIR and MIR values, based on the formula IR=CIR+K(MIR - CIR).
In this formula K is between 0 and 1 and is determined dynamically by the AU
according to overall demand in the cell and the prevailing conditions that
influence the performance of the wireless link. In some situations the minimum
rate (CIR) cannot be provided. This may result from high demand and poor
wireless link conditions and/or high demand in over-subscribed cells. When this
occurs, the actual information rate is lower than the CIR, and IR = (1+K)*CIR,
where K < 0. The K value to be used in the cell is advertised by the AU in every
beacon, and it is changed every second based on comparison of the traffic during
the last one second interval with the traffic during the previous previous one
second interval. The advertised K value is used by each SU to calculate the
amount of data that can be transmitted. This algorithm ensures fair resource
distribution among SUs, based on their configured CIR/MIR values.
The MIR Threshold Percent parameter determines the level of wireless link
utilization above which the MIR/CIR mechanism is activated. A Threshold of 0%
allows CIR only. A threshold of 100% means MIR only. For other values, if the
actual wireless link utilization is below the threshold, K is set to 1. As the link
utilization increases above the threshold, K is decreased as described above.
The simple solution for managing the information rate in such cases can result in
an unfair allocation of resources, as subscribers with a higher CIR actually
receive an IR lower than the CIR designated for subscribers in a lower CIR
bracket.
A special algorithm for graceful degradation is incorporated into the AU, ensuring
that the degradation of performance for each individual Subscriber Unit is
proportional to its CIR.
The MIR/CIR algorithm uses buffers to control the flow of data. To balance the
performance over time, a special Burst Duration algorithm is employed to enable
higher transmission rates after a period of inactivity. If no data intended for a
certain SU (in the AU) or for the AU (in an SU) is received from the Ethernet port
during the last N seconds, the unit is allowed to transmit to this destination N
times its allowed IR value without any delay. For example, if the Burst Duration
is set to 0.5 second (or more), then after a period of inactivity of 0.5 seconds up to
128 Kbits x 0.5 = 64 Kbits may be transmitted to a unit whose IR is 128 Kbps,
without any delay (provided overall conditions in the wireless link allow this
burst).

Kbps after a period of inactivity of 5 milliseconds or more.
4.2.6.6.2.6 Maximum Delay (SU only)
Sets the maximum permitted delay in the buffers system. As certain applications
are very sensitive to delay, if relatively high delays are permitted, these
applications may suffer from poor performance due to data accumulation in the
buffers from other applications, such as FTP. The Maximum Delay parameter
limits the number of available buffers. Data that is delayed more than the
permitted maximum delay is discarded. If the SU supports applications that are
very sensitive to delay, the value of the Maximum Delay should be decreased.
Valid values range from 300 to 10000 (milliseconds).
The default value is 5000 (milliseconds).
4.2.6.6.2.7 Graceful Degradation Limit (AU only)
Sets the limit on using the graceful degradation algorithm. In cases of over
demand, the performance of all SUs is degraded proportionally to their CIR
(IR=(100%-k%) x CIR). The graceful degradation algorithm is used as long as
k ≤ K, where K is the Graceful Degradation Limit. Beyond this point the simple
“brute force” algorithm is used. The Graceful Degradation Limit should be raised
in proportion to the demand in the cell. The higher the expected demand in a cell,
the higher the value of the Graceful Degradation Limit. Higher demand can be
expected in cases of significant oversubscription and/or in deployments where a

4.2.6.6.2.8 MIR Only Option (AU only)
When the MIR Only Option is enabled, it forces the MIR/CIR algorithm to use
MIR values only. The MIR/CIR algorithm determines the actual information rate
for each of the supported SUs under changing conditions of demand, based on
the configured CIR and MIR values. When the MIR Only Option is enabled, the
MIR/CIR algorithm is overridden and forced to operate with MIR values only. For
example, the AU attempts to enable all SUs to transmit/receive information at the
specified MIR value. When enabled, the graceful degradation algorithm, which is
a part of the CIR/MIR algorithm, is also disabled.
The default is Enable.

Traffic Prioritization
Each packet that is received from the Ethernet port is placed in either the High or
Low queue, according to the Traffic Prioritization parameters. When the MIR/CIR
mechanism decides that a packet must be sent, the High priority queue will be
checked first. If the High priority queue is not empty, the first element in the
queue is forwarded to the MIR/CIR mechanism. Packets from the Low priority
queue will be forwarded only if the High queue is empty.
The prioritization of the packets is done using different classifiers:
„ VLAN Priority
„ ToS Priority: IP Precedence or DSCP
„ UDP and/or TCP ports
Operation and Administration
197
Chapter 4 - Operation and Administration
Each one of these classifiers can be activated/deactivated. If more than one
classifier is activated, the priority of each packet will be determined by the
highest priority given to it by the active classifiers.
The Traffic Prioritization menu enables activating/deactivating each of these
classifiers, and configuring the applicable parameters for each classifier.
The Low Priority Traffic Minimum Percent parameter can be used to prevent
starvation of low priority traffic by ensuring that a certain number of low priority
packets is transmitted even at the expense of high priority traffic.
In addition, the Wireless Link Prioritization, which is a licensable feature, enables
to configure parameters that affect the prioritization of traffic in the wireless link
for packets with high/low priority from different units.
4.2.6.6.3.1 VLAN Priority Threshold
The VLAN Priority Threshold is applicable for Trunk and Hybrid Links only. It
enables defining the value of the VLAN Priority Threshold. If the VLAN Priority
field in a tagged frame is higher than the value of the VLAN Priority Threshold
parameter, the packet will be routed to the High queue. If the VLAN Priority field
is lower than or equal to this value, the packet will be transferred to the Low
queue (unless it is assigned a High priority by another classifier).
Valid values range from 0 to 7.
The default value is 7, which means that all packets get a low priority (equivalent
to disabling the VLAN-based classifier).
4.2.6.6.3.2 ToS Prioritization
The ToS Prioritization parameters enable defining prioritization in accordance

4.2.6.6.3.3.2 UDP Port Ranges
The UDP Port Ranges menu enables defining port ranges to be used as priority
classifiers when the UDP/TCP Port Ranges Prioritization Option is set to either
Enable Only for UDP or Enable for both UDP and TCP. All packets whose
destination is included in the list will be routed to the High queue. All other
packets will be routed to the Low queue (unless they were assigned a High
priority by another classifier).
The UDP Port Ranges menu includes the following options:
„ UDP RTP/RTCP Prioritization: Voice over IP is transported using Real Time
Protocol (RTP). The Real Time Control Protocol (RTCP) is used to control the
RTP. When an application uses RTP/RTCP, it chooses for destination ports
consecutive numbers: RTP port is always an even number, and the port with
the odd number following it will be assigned to RTCP.
If the administrator selects to prioritize only the RTP packets, then all the
packets with an odd numbered destination port will always have Low priority.
The packets with an even number for destination port will receive High
priority, if the port number is included in the specified ranges.
If the administrator selects to prioritize both RTP and RTCP packets, then all
packets whose destination port number is included is in the specified ranges
will receive High priority.
The available options are:
‘ RTP & RTCP
‘ RTP Only
The default is RTP & RTCP
„ Add UDP Port Ranges: This option enables adding UDP port ranges to the list
of priority port numbers. The list can include up to 64 ranges. It is possible to

4.2.6.6.3.4 Low Priority Traffic Minimum Percent
This feature ensures that a certain amount of low priority packets, specified by
the Low Priority Traffic Minimum Percent (LPTMP) parameter, is transmitted even
at the expense of high priority traffic.
The mechanism guarantees a low priority traffic with a rate of LPTMP * RT /100,
where RT symbolizes the allowed traffic rate. The high priority traffic will thus not
be able to exceed (100-LPTMP) * RT/100. If the system receives high priority
traffic at a rate higher than this figure, some high priority packets will be
discarded.
The range is between 0 and 100 (%).
The default value is 0 (%).
4.2.6.6.3.5 Wireless Link Prioritization Parameters (AU)
To better support delay-sensitive and other high-priority traffic, a set of Wireless
Link Prioritization parameters enables configuring parameters that affect the
processes of gaining access to the wireless media and of transmitting high/low
priority packets.
The Wireless Link Prioritization feature is a licensed feature and is available only
in units with the suitable Feature License.
The time interval between two consecutive transmissions of frames is called InterFrame Spacing (IFS). This is the time during which the unit determines whether
the medium is idle using the carrier sense mechanism. The IFS depends on the
type of the next frame to be transmitted, as follows:
BreezeACCESS VL System Manual
202
Menus and Parameters
„ SIFS (Short Inter-Frame Spacing) is used for certain frames that should be
transmitted immediately, such as ACK and CTS frames. The value of SIFS is
16 microseconds.
„ DIFS (Distributed coordination function Inter-Frame Spacing) is typically
used for other frame types when the medium is free. If the unit decides that
the medium is not free, it will defer transmission by DIFS plus a number of
time slots as determined by the Contention Window back-off algorithm after
reaching a decision that the medium has become free. DIFS equal SIFS plus
AIFS, where AIFS is a configurable number of time slots.
Under regular conditions, AIFS is configured to two time slots. To support
prioritization in the wireless link, we can configure a higher AIFS for low priority
traffic (AIFS of two time slots will always be used for high priority traffic as well as
AU’s transmissions of broadcasts/multicasts and beacons). This will give
advantage to units that need to transmit high priority traffic (depending also on
the configured values for the Contention Window parameters).
Other parameters related to transmission to the wireless media that can be
configured separately for high/low priority packets are the Number of HW Retries
and Burst Duration.
Typically, a lower value of Number of HW Retries should be configured for traffic
such as VoIP, which on the one hand is sensitive to delays and on the other hand
is less sensitive to missing packets than data traffic.
The Burst Duration, which defines the maximum duration of a burst, should be
set to a lower value for delay sensitive traffic. Typically the Burst Duration of the
AU should be set to higher value than that of the SUs, because of the higher
number of packets that should be transmitted by the AU.
When the Wireless Link Prioritization feature is enabled, the following parameters
are not applicable:
„ Arbitration Inter-Frame Spacing (AIFS)
„ Number of HW Retries
„ Burst Mode Option
„ Burst Mode Time Interval
When an SU with a SW version below 4.0 tries to associate with an AU that has
the Wireless Link Prioritization feature enable, the AU will generate a trap that
will include information about this SU. In this way the system administrator can
be alerted that the SU should be upgraded. This is necessary because otherwise
Operation and Administration
203
Chapter 4 - Operation and Administration
an SU that does not support the Wireless Link Prioritization feature will send all
the traffic as high priority.
CAUTION
Verify that all SUs served by an AU with the Wireless Link Prioritization Option enabled use a SW
version that supports this feature (SW version 4.0 and higher). Otherwise, overall performance and
quality of service in the cell may be reduced since all data from an SU with SW version below 4.0
will be sent with high priority.
The Wireless Link Prioritization Parameters menu includes the following:
4.2.6.6.3.5.1 Wireless Link Prioritization Option
The Wireless Link Prioritization Option enables or disables the Wireless Link
Prioritization feature.
The default option is Disable.

to 10 milliseconds) or 0 to disable bursts for low priority packets.
The default is 20 (5 milliseconds).
4.2.6.6.4
DRAP Parameters (AU only)
DRAP (Dynamic Resources Allocation Protocol is a protocol that can be used by
the AU to communicate with Voice and Networking Gateways connected to SUs
served by it, enabling identification of these Gateways. It also enables managing
voice calls made by Voice Gateways (VG).
The AU keeps track of all current voice calls and, upon receiving from a VG a
request for a new call, compares the current number of calls to the maximum
allowed number. If the maximum allowed number has been reached, the AU will
not confirm the request.
The DRAP feature is applicable only for gateways that support DRAP.
The following is a description of DRAP-related parameters:

Security Parameters
BreezeACCESS VL systems can support encryption of authentication messages
and/or data frames using one of the following encryption standards:
„ WEP Wired Equivalent Privacy algorithm. WEP is defined in the IEEE 802.11
Wireless LAN standard and is based on the RSA’s RC4 encryption algorithm.
„ AES OCB Advanced Encryption Standard. AES is defined by the National
Institute of Standards and Technology (NIST) and is based on Rijndael block
cipher. AES OCB (Offset Code Book) is a mode that operates by augmenting
the normal encryption process by incorporating an offset value.
„ FIPS 197 is certified for compliance with Federal Information Processing
Standards. It provides encryption and message integrity in one solution and
implements the Advanced Encryption Standard using Rijndael block cipher.
NOTE
The FIPS 197 encryption algorithm is a licensed feature, and is available only in units with the
required license. FIPS 197 can be supported only in Access Units with HW revision C or higher.
FIPS 197 feature license is not available for AUS unit.
The following parameters are available through the Security Parameters menu (in
certain units some or all of the security options may not be available):

selected unit. The following two options are available:
Operation and Administration
207
Chapter 4 - Operation and Administration
„ Open System: An SU configured to Open System can only associate with an
AU also configured to Open System. In this case, the authentication
encryption algorithm is not used.
„ Shared Key: The authentication messages are encrypted. An SU configured to
use a Shared Key can only be authenticated by an AU configured to use a
Shared Key, provided the applicable Key (which means both the key number
and its content) in the AU is identical to the key selected as the Default Key in
the SU.
The default is Open System.
NOTE
The Shared Key option cannot be selected before at least one Key is defined. In the SU, a Default
Key that refers to a valid Key must be selected.
The AU and all the SUs it serves should be configured to the same Authentication Algorithm option.
Mixed operation is not supported.
4.2.6.7.2
Data Encryption Option
The Data Encryption Option allows enabling or disabling data encryption. When
enabled, all data frames, including frames using management protocols such as
Telnet, FTP, TFTP, SNMP, DHCP and ICMP, are encrypted.
The default is Disable.
NOTE
„ The AU and all the SUs it serves should be configured to the same Data Encryption Option.
Mixed operation is not supported.
„ A unit with Data Encryption Option enabled can accept non-encrypted data frames.
„ The Maximum Number of Associations must be set to a value of 124 or lower to enable Data
Encryption. As long as Data Encryption is enabled, the Maximum Number of Associations
cannot be set to a value higher than 124.The Maximum Number of Associations Limit (512
when Data Encryption is disabled, 124 when Data Encryption is enabled) is indicated in the
Show Air Interface Parameters display.
4.2.6.7.3
Security Mode
The Security Mode option enables selecting the algorithm to be used for
encrypting the authentication messages and/or data frames.
The available options are WEP, AES OCB and FIPS 197 (if available).
The default is WEP.
4.2.6.7.4
Default Key (SU only)
The Default Key defines the Key to be used for encrypting/decrypting the
authentication messages (Shared Key mode) and/or data frames (Data
Encryption enabled). The AU learns the Default Key from the SU provided it is
BreezeACCESS VL System Manual
208
Menus and Parameters
one of the Keys defined in the AU. The AU may use different keys when
authenticating and/or communicating with different SUs.
Available values range from 1 to 4.
The default is KEY # 1.
4.2.6.7.5
Default Multicast Key (AU only)
The Multicast Default Key defines the Key to be used for encrypting multicasts
and broadcasts when Data Encryption is enabled.

authentication algorithm or Data Encryption can be used. To support proper
operation, both the Key # and the content must be identical at both sides of a
wireless link.
Each Key is a string of 32 hexadecimal numbers. For security reasons, it is a
“write only” parameter, displayed as a string of asterisks (“*”).
The default for all 4 Keys is 000…0 (a string of 32 zeros), which means no key.
4.2.6.7.7
Promiscuous Authentication (AU only)
The Promiscuous Authentication mode enables new SUs to join an active cell
where Shared Key operation and/or Data Encryption are used, even if this SU
does not have the correct security parameters. In promiscuous mode, all
downlink transmissions (from AU to SUs) are not encrypted, allowing remote
configuration of security parameters, regardless of the current settings in the SUs
of the parameters related to data encryption. After a new SU joins the cell it
should be remotely configured with the proper parameters (or upgraded). When
the SU is configured properly, the Promiscuous Mode should be disabled.
The default is Disable.
NOTE
Do not leave the AU in the enabled Promiscuous Authentication mode for prolonged periods. Use it
only when absolutely necessary, perform the required actions as quickly as possible and disable it.
The unit will return automatically to Promiscuous Authentication disabled mode after reset.

Appendix B - File Download and Upload Using TFTP
The File Download/Upload feature simplifies the task of remotely configuring a
large number of units using TFTP protocol. By downloading the configuration file
to a PC it is possible to view all the parameters configured for the unit, as a plain
ASCII text file. It is necessary to edit the file using a simple editor and remove
certain parameters or change their values prior to uploading the configuration to
another unit. The file loading procedure can also be used for uploading a feature
license file or an updated country code file to multiple units.
When multiple configurations are being done simultaneously, that is, the file is
being uploaded to several units, it is recommended that the file will include only
the required parameters.
In the configuration file, the following three fields represent each parameter:
1
A symbolic string similar to the name of the parameter in the Monitor
program, followed by "=".
2
The value of the parameters, which uses the same values as the Monitor
program.
3
An optional comment. If used, the comment should start with a ";" character.
An unknown parameter or a known parameter with a value that is invalid or out
of range will be ignored.
Use the SNMP write community string (the default is “private”) to define both the
uploaded file (put) and the downloaded file (get). The file should be transferred in
ASCII mode.
Use the extension cfg for a configuration file.
Use the extension cmr for the Operator Defaults file.
Use the extension fln for a Feature License file.
Use the extension ccf for a Country Code file.
Feature license and country code files include multiple strings, where each string
is applicable only for a certain unit identified by its MAC address. When
uploading a feature license or a country code file to multiple units, each unit will
accept only the parts that are applicable for itself.

Appendix E - Parameters Summary
In This Appendix:
„ The tables provide an at a glance summary of the configurable parameters,
value ranges, and default values. In addition, each parameter entry also
includes an indication as to whether the parameter is updated in run-time or
whether the unit must be reset before the modification takes effect (“No” in
the Run-Time column indicates that a change to the parameter will take effect
only after reset).

F.1
Ethernet Port Connection Problems
Problem and Indication
Possible Cause
The Ethernet Integrity Indicator (the yellow
LED embedded in the Ethernet connector)
is off, and/or the Ethernet Activity Indicator
(the green embedded LED) does not blink
when there should be traffic on the Ethernet
port.
The unit does not respond to ping.
Wrong type of Ethernet
cable
If connected directly to PC-use a
crossed cable. Otherwise-use a
straight cable
Faulty Ethernet cable
Replace cable
Wrong IP configuration
Make sure that the PC is on the same
subnet as the unit*.
Wrong Ethernet port
operation mode
Make sure that the speed and duplex
settings in the PC match the
configuration in the unit (the default is
Auto Negotiation)
Make sure all relevant parameters are
configured properly
Wrong Management
VLAN, User Filtering,
Access to
Management..
Corrective Action
* If the IP parameters of the unit are unknown, use the Set Factory Defaults utility to restore
the default factory configuration of all parameters (except to Passwords, general FTP
parameters and AU’s Frequency). The IP address of the unit after setting to factory defaults is
10.0.0.1.
BreezeACCESS VL System Manual
238
SU Association Problems
F.2
SU Association Problems
Problem and Indication
SU does not associate with AU
Possible Cause
Corrective Action
Wrong configuration
Check proper configuration of basic parameters:
„ ESSID
„ Sub-band and frequencies subset
„ Best AU parameters
„ ATPC Option
„ Transmit Power
„ Maximum Transmit Power
„ Antenna Gain
„ Security parameters: Authentication
Algorithm, and Default Key. If necessary-use
Promiscuous Mode in AU.
Access is denied by AU
Verify that the SU is not included in MAC Address
Deny List of the AU.
Link quality is too low
„
„
„
Verify that unit is in coverage area of AU
according to radio planning.
Verify that antenna is directed toward the AU
Try to improve location/height of antenna.

Low Throughput Problems
Problem and Indication
Low throughput is suspected
Possible Cause
Corrective Action
„
Ethernet link problems
(Check the dominant Modulation
Level in Per rate Counters and
see expected throughput in the
“Expected Throughput” table
below)
„
Wrong configuration of
Maximum Modulation
level
Low throughput of
multicast/broadcast traffic
Non-optimal configuration
of Multicast Modulation
level
High retransmissions rate
Interference problems
(retransmissions rate in
excess of 15%)
Verify proper settings of Ethernet
operation mode (actual Ethernet speed
of 100 Mbps).
Check Ethernet counters
Verify that Maximum Modulation level is not
set to a value that is not too low according to
the “Recommended Maximum Modulation
Level” table below.
A value that is too low (see the
“Recommended Maximum Modulation Level”
table below) may degrade throughput of
broadcast and multicast traffic.
Check for interference using the Spectrum
Analysis Mode. If necessary, change the
operating frequency of the AU.
