Radio Characteristics
The Aironet Client Card uses a radio modulation technique known as
Spread Spectrum Transmission or SST. This modulation technique provides high data bandwidth and excellent immunity from interference and
multipath effects.
Two versions of the Radio Module are offered which differ in their frequency band of operation:
Aironet PC1200 - 900 MHz band (902 - 928 MHz range).
Aironet PC2200 - 2.4 GHz band (2.400 - 2.485 GHz range).
Data is transmitted over a half-duplex radio channel operating at data
rates up to 860 kb/s (PC1200) and 2 Mb/s (PC2200).
Radio Ranges
The Aironet Client Card Radio Module is used in indoor wireless Radio
Networks. The radio range achieved depends on the following:
Data Bit Rates - Better receiver gain at lower data bit rates
Lower bit rate links have an advantage over higher bit rate links. There
is a decrease in receiver threshold as the radio data rate increases. The
maximum radio range is achieved at the lowest workable data bit rate.
Antenna Type and Placement - Increased range with antenna height
The key to maximizing range indoors is to place the Access Point
antenna above obstacles such as cabinets, shelves, etc. An antenna
mounted on the ceiling provides excellent coverage.
Introduction to the Aironet PCMCIA Wireless LAN Adapter
xiii
Openness of the Environment - Open areas are better than closed
The less cluttered the work environment, the greater the range.
Building Materials - Drywall vs Concrete
Floor-to-floor radio penetration depends on the building materials used
between floors. For example, the range will be greater if the signal is
passing through drywall rather than concrete blocks.
Table 0.1 provides a summary of typical radio ranges to be expected for
different situations.

Security Features
The Aironet Client Card provides secure and highly reliable data communications by employing Spread Spectrum Technology, previously
developed for military “anti-jamming” and “low probability of intercept” radio systems.
xiv
Introduction to the Aironet PCMCIA Wireless LAN Adapter
Additional security is achieved through the use of a System Identifier
(SID). The SID is a unique, 6 hexadecimal digit value that is attached to
each packet sent out over the radio. With over 8 million possible SID
settings, a high degree of privacy and security can be assured. See Chapter 3 - Utilities for detailed information on setting the System Identifier.
Radio Network Terminology
When configuring your system, and when reading this User Guide, keep
in mind the following Radio Network terminology:
Network Tree - Conceptually, Aironet’s Advanced Radio Local Area
Network (ARLAN) is designed like an upside-down tree, (see Figure
0.2) with a Root Unit at the top, and Repeaters and Radio nodes branching down and out from the Root.
Root Unit - An Access Point which is located at the top of a Network
Tree. The Root Unit is the starting point in the network and contains
information in its Registration Table regarding all nodes on the network.
Repeaters - A Repeater is a wireless Access Point which is used to
extend the radio range of your network. A single Access Point is limited
to a specific RF range. If your system configuration includes nodes outside this range, you will need to add a Repeater in order for them to
communicate.
Radio Node - A PC, notebook computer, etc. containing a Radio Card.
End Node - A Radio Node that is located at the end of the Network
Tree.
Introduction to the Aironet PCMCIA Wireless LAN Adapter
Figure 0.2 - Network Tree
Wired LAN
Root Unit
Repeater
End Node
End Node
xv
xvi
Introduction to the Aironet PCMCIA Wireless LAN Adapter
Parent/Child Node - Refers to the relationships between nodes on the
Network Tree. For example, the Root Unit (at the top of the tree) would
be the Parent of the Repeater and the Repeater would be the Parent of
the end nodes. Conversely, the end nodes would be the Children of the
Repeater and the Repeater would be the Child of the Root Unit.
Registration - Each Access Point (Repeater or Root Unit) on the Radio
Network contains a Registration Table, used to control the routing of
packets from the Ethernet and the Radio Network. The table controls the
routing of packets by maintaining entries for all radio nodes situated
below the Access Point on the Network Tree.
Power Saving Protocol (PSP) and Non-Power Saving Protocol The Power Saving Protocol allows computers (usually portable computers) to power up only part of the time to conserve energy. If a Radio
node is using the Power Saving Protocol to communicate with the network, the Access Points must be aware of this mode and implement
additional features such as message store and forward. While the PSP
Mode does provide greater battery life, it does increase the response
time for the data.
Registration Modes
The Aironet Client Card can be used in either ARLAN (default), PSP or
Non-ARLAN registration mode.
ARLAN Mode (Microcellular Architecture) - A high-traffic Radio
Network with one or more Access Points placed on a cabled backbone
LAN, and Aironet Client Cards installed in remote Radio nodes (PCs
and notebook computers).
Each Radio node registers to and communicates with the closest, or
user-specified Aironet Access Point. The Access Points perform routing
functions by moving data packets to and from the cabled LAN and
remote Radio nodes.
This mode provides automatic circuit hand-off and message forwarding,
as an Aironet Client Card user roams between LAN Access Point microcells. In this way, large-scale, wireless LANs are configured.
Introduction to the Aironet PCMCIA Wireless LAN Adapter
xvii
PSP - Same as ARLAN Mode, except that it is used for Aironet Client
Cards installed in remote battery-powered Radio Nodes, i.e. notebook
computers. The Power Saving Protocol (PSP) conserves battery power at
the cost of decreased throughput by periodically turning off the radio
(See also Power Saving Protocol on previous page.)
Non-ARLAN Mode - A low-traffic Radio Network comprised strictly of
Radio nodes (PCs, File Servers, notebook computers, etc.) fitted with
the Aironet Client Card.
In Non-ARLAN Mode, Access Points are not used, and ARLAN microcellular architecture is not utilized, since data is transmitted directly
between the Radio nodes. The Radio nodes can operate in a peer-to-peer,
or in a client-server network relationship depending on the network
operating system being used.
Note that Non-ARLAN mode does not support Power Saving Protocol
on Radio end nodes (see Figure 0.3).
Aironet PCMCIA Network System Configurations
The Aironet Client Card can be used in a variety of Network system configurations. Examples of some common system configurations are outlined below, and shown on the pages that follow, along with a brief
description of each. All configurations shown can be created with either
900 MHz or 2.4 GHz models.

A Micro-Cellular Network can be created by placing two or more Access Points on an
Ethernet LAN, and allowing remote workstations equipped with Aironet Client Cards to
register to the Access Points. The ARLAN protocols allow remote workstations to move
from the domain of one microcell to another. The process is seamless and transparent,
and the connection to the File Server or host is maintained without disruption. This configuration is particularly useful with portable or mobile workstations.

IP. An IP address must also be configured for the Access Point.
1. From the link test command menu, enter the following parameters:
„
IP address of Aironet Access Point:
This parameter specifies the IP address of the Access Point with
which you want to test the RF link. Set this value before running the
link test.
„
Number of Packets:
This parameter specifies the number of packets the link test will
attempt to send. The display will show the number of packets of the
specified size that are successfully transmitted and received.
„
Packet Size:
This parameter specifies the size of the data packet to be sent to the
Aironet Access Point. Be aware that the TCP/IP stack that comes
with Windows 95 will fragment packets greater than 512 bytes.
Therefor, the number of packets transmitted will not match the number of packets received (even if none are lost) if the packet size is
greater than 512 bytes.

„
Priority
Name
The station name is displayed in the table of connected devices on the
Access Point. It provides a logical name to determine which machines
are connected without having to memorize every MAC address. The
name can be up to 16 characters.
Setting the System Identifier
The SID is a 4-byte, hexadecimal digit value that is attached to each
packet sent out over the radio. Establishing a SID allows you to group
nodes into a microcellular network and exclude those nodes that are
within radio range on other networks.
The SID value must be an even number, cannot exceed 8 digits and must
start with 00 or 02. An example of valid SID values are: 00000102,
0200AA14, 00013A18, 007F6380. The default SID is 00000002.
Since nodes will only receive packets from other nodes with a matching
SID, you must make sure that the Aironet PCMCIA Client Card is set
with the same SID as other nodes on your Radio Network.
The System Identifier option also allows you to have the system automatically set a SID value for you. To generate an automatic SID value,
click once on AUTO with the mouse, or press F10.
i
NOTE: All other units in the system must be manually set to this value.
Utilities
3-7
Registration Mode
Use the Registration Mode parameter to specify whether you are operating in ARLAN, PSP or Non-ARLAN mode. The default setting is
ARLAN Mode.
„
Set to “ARLAN” when operating with Aironet Access Points
„
Set to “PSP” when operating with battery-powered devices
„
Set to “Non-ARLAN” when operating in Peer-to-Peer mode with
other Aironet Client Cards and no Aironet Access Points (see Registration Modes for a detailed explanation).
Setting the Specified Router
This parameter only applies to the ARLAN and PSP registration modes.
Use the Specified Router parameter to specify a Parent Access Point for
the Aironet PCMCIA Client Card to register to.
„
If you want the Aironet PCMCIA Client Card to register to a specific
Parent Access Point, you should enter the Network Address of that
Access Point. All other Access Points will be ignored even if their
radio link would be better.
Keep in mind, however, if the specified router is not heard from
within the Specified Router Timeout time, then the unit will register
with the Access Point at the root of the Radio Network Tree, or the
Access Point that is closest to the top of the Radio Network tree, and
that is within radio range (see Setting Advanced Radio Parameters
for information on Specified Router Timeout).
„
If you do not want to specify a specific Parent Access Point, you
should leave the parameter at the default value of “Not Specified”.
With this value, the Client Card will automatically register to the
Access Point at the root of the Radio Network Tree or the Access
Point that is closest to the top of the Radio Network tree, and that is
within radio range.
3-8
Aironet PCMCIA Wireless LAN Adapter
Selecting a Channel Number, Bitrate and Frequency
The Channel Number parameter appears for all 1200 Series models and
the Bitrate and Frequency parameters appear for the Aironet 2200
Series only.
Keep in mind the following when selecting Channel Numbers, Bitrates
and Frequencies:
„
Appendix B contains both North American and International bit
rates, frequencies and channel sets which can be used as a guide in
selecting the appropriate combinations for both 900 Mhz and 2.4
GHz models.
„
The tendency is to select the highest data rate available for the Client Card. The trade-off, however, is that the higher the rate, the
lower the quality of the radio signal, and therefore, the shorter the
range a packet may be sent successfully.
„
If you find excessive interference on the channel or bitrate\frequency you have chosen, try other channels, or combinations until
you find one that is more reliable.
„
Use the Linktest option to test the transmission quality between the
Client Card and other nodes on the Radio Network.
When you select the Channel Number parameter for 1200 Series models,
the 900 MHz Channel Set appears. Choose a channel number from the
available channel set.
When you select the Bitrate and Frequency parameter for the 2200
Series, the 2.4 GHz Bitrate and Frequency window appears. Choose a
bitrate and frequency combination from the set.
Setting the Priority
The priority setting is used by the radio MAC (Media Access Control) to
allocate access to the radio link. The higher the priority, the more likely
the Wireless LAN Adapter will be first to successfully transmit a packet
when multiple Aironet devices are trying to transmit at the same time.
The percentage of devices that are not using normal priority should be
kept low (10% or less).
Utilities

Network Parameters
User modifiable parameters are limited to the your choice of MAC
Address:
„
Factory MAC Address: This is the unique hardware factory MAC
address which is guaranteed to be unique. Unless you have a very
good reason to define your own MAC address, it is STRONGLY
RECOMMENDED that you use the factory MAC address.
„
User Defined MAC Address: If you must define your own MAC
address, you can enter it here. If you do not use a unique value, you
may not be able to communicate to your wired network at all. For
this reason, it is STRONGLY RECOMMENDED that you use the
factory MAC address. The MAC address is 12 hexadecimal digits.
You do not need to use delimiters, but you can use spaces or the
colon character.
Setting ARLAN, MAC, DDP, and PSP Parameters
These parameters should only be set or modified by experienced users.

Aironet PCMCIA Wireless LAN Adapter
Setting System Identifier
The SID is a 4-byte, hexadecimal digit value that is attached to each
packet sent out over the radio. Establishing a SID allows you to group
nodes into a microcellular network and exclude those nodes that are
within radio range on other networks.
The SID value must be an even number, cannot exceed 8 digits and must
start with 00 or 02. An example of valid SID values are: 00000102,
0200AA14, 00013A18, 007F6380. The default SID is 00000002.
Since nodes will only receive packets from other nodes with a matching
SID, you must make sure that the Aironet Client Card is set with the
same SID as other nodes on your Radio Network.
The System Identifier option also allows you to have the system automatically set a SID value for you. To generate an automatic SID value,
click once on AUTO with the mouse, or press F10.
i
NOTE: All other units in the system must be manually set to this value.
Setting the Radio Node ID
The Radio Node ID represents the last 2-bytes of the 6-byte Network
Identifi er, and is used to customize the radio address for the Aironet
Client Card.
If your LAN addresses are locally administered, you may want to set the
2-byte Radio Node ID to match those used on your LAN. If not, you
should ignore this parameter and use the Network Identifier outlined
below.
Utilities
3 - 19
Setting the Network Identifier (NID)
The Network Identifier represents the 6-byte radio address of the Aironet Client Card. In using the NID, keep in mind the following:
„
The NID will override the 2-byte Radio Node ID address.
„
The address must be unique across the entire network.
„
If the NID is left at the default of 00:00:00:00:00:00 it will use a
factory assigned address.
Setting the Router ID
The Router ID is not required for the Aironet Client Card.
Setting the Specified Router
This parameter only applies to the ARLAN and PSP registration modes.
Use the Specified Router parameter to specify a Parent Access Point for
the Aironet Client Card to register to.
„
If you want the Aironet Client Card to register to a specific Parent
Access Point, you should enter the Network Address of that Access
Point. All other Access Points will be ignored even if their radio link
would be better.
Keep in mind, however, if the specified router is not heard from
within the Specified Router Timeout time, then the unit will register
with the Access Point at the root of the Radio Network Tree, or the
Access Point that is closest to the top of the Radio Network tree, and
that is within radio range (see Setting Advanced Radio Parameters
for information on Specified Router Timeout).
„
If you do not want to specify a specific Parent Access Point, you
should leave the parameter at the default value of “Not Specified”.
With this value, the Client Card will automatically register to the
Access Point at the root of the Radio Network Tree or the Access
Point that is closest to the top of the Radio Network tree, and that is
within radio range.
3 - 20
Aironet PCMCIA Wireless LAN Adapter
Setting Root or Repeater Mode
The Mode parameter is not required for the Aironet Client Card.
Establishing a Device Name
The Device Name parameter is used to establish a 15-byte ASCII name
for the Aironet Client Card. The Device Name is optional and may be
left blank.
If you choose to assign a name, and you are operating in ARLAN mode,
the name will appear in the Aironet Access Point’s Registration Table.
Duplicate names are allowed.
To have the system generate an automatic name, click once on AUTO
with the mouse, or press F10.
Setting the MAC (Media Access Control) Priority
Use the Priority parameter to set the priority of the Aironet Client
Card’s Radio MAC to —normal, high or highest. The higher the priority
set, the more likely this unit will be first to successfully transmit a
packet when multiple units are trying to transmit at the same time.
The percentage of units on your Network that you set to other than “normal” should be kept small—10 percent or less.
Setting the Radio Parameters
Use the Radio Parameters to select a Channel Number or Bitrate and
Frequency. When you select the Radio parameters a window similar to
the following appears.

Selecting a Channel Number, Bitrate and Frequency
The Channel Number parameter appears for all 1200 Series models and
the Bitrate and Frequency parameters appear for the Aironet 2200
Series only.
Keep in mind the following when selecting Channel Numbers, Bitrates
and Frequencies:
„
Appendix B contains both North American and International bit
rates, frequencies and channel sets which can be used as a guide in
selecting the appropriate combinations for both 900 Mhz and 2.4
GHz models.
„
The tendency is to select the highest data rate available for the Client Card. The trade-off, however, is that the higher the rate, the
lower the quality of the radio signal, and therefore, the shorter the
range a packet may be sent successfully.
„
If you find excessive interference on the channel or bitrate\frequency you have chosen, try other channels, or combinations until
you find one that is more reliable.
„
Use the Linktest option to test the transmission quality between the
Client Card and other nodes on the Radio Network.
When you select the Channel Number parameter for 1200 Series models,
the 900 MHz Channel Set appears. Choose a channel number from the
available channel set.
When you select the Bitrate and Frequency parameter for the 2200
Series, the 2.4 GHz Bitrate and Frequency window appears. Choose a
bitrate and frequency combination from the set.

(FFFFH) cause an infinite time to be used thus forcing the device to register to the specified Router and only that Router.
Refresh Period - Only applies to the ARLAN (Non-PSP) registration
mode. Sets the time that the device will wait to refresh its registration is
no other transmission has occurred. The units of this parameter are 0.01
second. Values can be entered in Decimal Mode or Hexadecimal Mode.
The value 0 causes a time of 60 seconds to be used, while a value of
65535 (FFFFH) causes an infinite time to be used, thus disabling
refresh.
ARL Threshold - Sets the ARL (Average Retry Level) Threshold. When
the cumulative ARL level reaches the threshold, the Aironet Client Card
will attempt to find a better Router to register to. Values can be entered
in Decimal Mode or Hexadecimal Mode. The value 0 causes a threshold
of 8 to be used. The value 255 (FFH) causes an infinite threshold to be
used (see also ARL Decay).
ARL Decay - Sets the ARL (Average Retry Level) Decay. After each
successful transmission, the cumulative ARL level is increased by the
number of retries that occurred and then decreased by this Decay. The
value 0 causes a decay of 1 to be used (see also ARL Threshold)

seconds to be used.
Fast Poll Delay - Specifies the time before the Fast Poll Period takes
effect after the transmission of a data packet. This parameter is useful in
transaction based environments where the host takes a minimum amount
of time to generate a response. Values can be entered in Decimal Mode
or Hexadecimal Mode.
Fast Poll Period - Sets the time that the device will wait to poll the
Router for waiting data, once a non-empty data frame is either received
or transmitted. This time must be less than the Poll Period to have an
effect. The units of this parameter are 0.001 seconds. Values can be
entered in Decimal Mode or Hexadecimal Mode. The value 0 causes a
time of 0.125 seconds to be used. Only used in PSP registration mode.
Utilities

Performing a LinkTest (Linktest)
Use the Linktest function to test the link quality between the Aironet
Client Card and other nodes on the Radio Network.
When you run a Linktest, the Client Card sends a sequence of packets to
a target destination node—either an Aironet Client Card (if running in
Non-ARLAN mode) or to an Aironet Access Point (if running in
ARLAN mode). If the radio quality is good, the target destination will
receive the packet then send the same packet back.
Before you run the Linktest, make sure the target destination node is
powered up with the antenna attached, is within radio range, and is set to
the same SID, bit rate and frequency, or channel.
The Aironet PCMCIA unit displays the number of packets sent, number
received, and percentage lost, which is a reflection of the link quality.
Keep in mind that packets will be lost, however, the upper layer drivers
and software combined with radio retries ensure a constant connection.
When you select the Linktest parameter, the Linktest menu appears. To

default values are used for the linktest. If you edit these values, exit the
Linktest menu, and then re-enter, the values shown will be those that
were last set, not the defaults. The only exception is the default Destination Address, which is updated on restart into the Linktest.
Packet Length (default 512 bytes)
The default packet length of 512 data bytes is the recommended setting.
The length of the packet can be set between 1 to 1500 bytes.
Number of packets to send (default 100)
The range of packets that can be sent is 0 to 9999. You can increase the
accuracy of the Linktest by increasing the number of packets. It is not
recommended that you send less than 100 packets.
Destination
The default destination address is a broadcast address and must be used
when in ARLAN mode. In Non-ARLAN mode, you can specify the
address of a specific target node (another Aironet Client Card only).
Pause time between each repetition (default 3 seconds)
If running the Linktest repeatedly, the pause time between tests can be
set from 1 to 9999 seconds. (see Perform Linktest/Continuous Linktest).
Number of packets per each statistics update (default 5)
While the Linktest is running, the screen displays updated statistical
information regarding the link performance. You can adjust how often
this display is updated, within a range of 1 to 9999 seconds.
Perform Linktest/Continuous Linktest
If the Linktest is run once, it will stop after the specified number of
packets are sent. In continuous mode, the Linktest runs continuously
until it is aborted by pressing Control-C. A Continuous Linktest also
shows the regular linktest statistics, plus cumulative statistics. It is a
good idea to run the Linktest several times to ensure that the link quality

Troubleshooting Tips
If you are having trouble with your Client Card, here’s a list of things to
try before you call Technical Support for assistance. These procedures
take only a few minutes, and 90 percent of the time you can solve the
problem yourself.
If the Workstation does not boot after installing the Client Card Driver
A base memory address or IRQ conflict likely exists. To resolve this
problem change the Client Card’s base memory addresses and IRQ settings until you find a combination that works. If you change these settings, make sure you change the Client Card parameters as well using
the ARLANDGS utility. (See Chapter 3 - System Configuration.)
Troubleshooting and Performance
4-3
If you’re unable to communicate with some or all nodes on the Radio
Network
„
Check to be certain that the Device Driver is loaded properly. (see
Chapter 1 - Client Card Installation and Chapter 2 - Client Card
Driver Installation).
„
Check that the Workstation is not out of radio range with other
nodes on the Radio Network (see Performance Tips).
„
Make sure the Client Card’s antenna is attached and is not shielded
by surrounding metal, or otherwise poorly positioned. (see Performance Tips.)
„
Make sure the SID and Data Rate/Frequency/Channels settings are
the same for all nodes on the Radio Network. Check the driver configuration files (PROTOCOL.INI and NET.CFG) for proper settings.
„
Run the ARLANDGS.EXE or WinDGS.EXE diagnostics to confirm
the hardware con-nections.
If the System operation is slow or you are receiving numerous network
time-out errors
Run the ARLANDGS.EXE or WinDGS.EXE utility and perform a Linktest to check the link quality between nodes on the Radio Network.
If results are marginal, then either the antenna placement is poor or the
path loss is too high. If the Linktest results are good, check to make sure
the network traffic load is not too high. (see Performance Tips.)
Error Messages
Error messages inform you when there is a problem with the software or
the Client Card.
If you get an error message, write down the message and any instructions the message might offer to remedy the situation. This information
will be helpful to the Technical Support personnel should you need to
call for assistance. Shown below are some of the more common error
messages you may receive.
4-4
AironetPCMCIA Wireless LAN Adapter
“Time-out waiting for interrupt” Error initializing ARLAN PCMCIA
The Client Card may not be properly seated in the PCMCIA slot.
“LANcard RAM region test failed” Error initializing ARLAN PCMCIA
An extended memory manager may be using the requested region of
memory. Ensure that the memory region selected for the Aironet PCMCIA is excluded from use. (e.g. EMM386 x=D000-D1FF)
Performance Tips
If you are experiencing performance problems, here’s a list of things to
try before you call Technical Support for assistance.
Improving your Radio Range
„
Access Point antennas should be located in the center of the area to
be covered.
„
Avoid placing any antenna where it may be shielded by surrounding
metal surfaces.
„
Antennas should be placed at the highest elevation possible, with a
minimal number of obstacles between it and the direct path to other
nodes. Common obstacles often encountered are furniture, walls and
partitions.
„
Orient the antenna in a vertical direction.
Troubleshooting and Performance
4-5
Reducing Network Load
„
Reserve the network for accessing shared data files, common communications utilities and printer facilities.
„
Install and run programs from a workstation’s local drive.
„
Install copies of overlay files on the workstation’s local drive.
„
When editing files, copy to a local directory prior to opening the file.
„
Configure application programs to create temporary files on local
disks where possible.
Testing the Radio Link
„
The LED Display on the Aironet Client Card can be used to assess the
condition of the Client Card radio link. (See Chapter 3 - System Configuration for an explanation of the LED displays.)
„
Run the ARLANDGS.EXE or WinDGS.EXE utility and perform a
Linktest to test the link quality between nodes on the Radio Network.
When running the Linktest, look for consistent results. It is a good
idea to establish “benchmark” tests on those nodes with a quality link,
and then set other nodes with the same data rate and frequency settings (see Chapter 3 - System Configuration for instructions on running a Linktest).
