5 km.
!
Channel -
Channel selection varies, depending on the type of unit.
For BU-DS.5800 units, select the channel that the unit will use by selecting a value (range: 1-14, depending on your regulatory
domain) from the Channel drop down menu. Refer to Table 3-2 for
the list of corresponding frequencies.
Manual Revision: 1.0
BreezeCONFIG DS
3-13
For RB-DS.5800 units, there are two channel setting options: if you select the
Fixed Channel
option by clicking the appropriate radio button, then the RB-DS.5800 will search for the BU-DS.5800 unit on the selected channel (from the Channel pull down field) and synchronize with it. The channel you select must match the channel selected in the BU-DS.5800 unit at the other end of the link.
If you select the
Scanning Mode
option (by selecting the appropriate radio button), you can specify preferred channels by clicking one or more of the buttons displayed at the bottom of the window. In this mode, the RB-DS.5800 will first search for the BU-DS.5800 unit on the channel you select in the Channel pull down field and synchronize with it if the link is established. If the RB-DS.5800 does not find the BU-DS.5800, it will scan and search for one of the preferred channel frequencies you selected. If it does not find the
BU-DS.5800 on any of the preferred channels, it will continue to scan until it finds the BU-DS.5800 on one of the channels permitted according to the regulatory domain.
Table 3-1 describes the channels used by the DS.5800, the default channel, the maximum output power and the default output power.

Figure 3-8: Security Tab
Alvarion
3-16
BreezeNET DS.5800 System Manual
This tab displays information regarding the unit’s security configuration. Wired Equivalent Privacy (WEP) is an authentication algorithm that protects authorized Wireless LAN users against eavesdropping and is implemented in BreezeNET DS.5800 units. WEP is defined in the IEEE 802.11b standard. This encryption is applicable for both authentication and data and the key length is 40 bits.
DS.5800 units can use one of the following authentication algorithms
(as defined in the IEEE 802.11b standard).
!
Open System
– Any station in the WLAN can associate with any other unit and receive and transmit data freely(null authentication).
!
Shared Key
– Only stations using a shared key encryption are allowed to associate.
The default authentication algorithm is
Open System
.
If you select the Shared Key algorithm, set the following parameters:
!
Default Key ID
– Sets the key for encryption.
!
WEP Key
– Defines the encryption keys used. Define each key by clicking the appropriate WEP Key row and entering ten hexadecimal characters (five sets of two characters each) for each of the four keys. After clicking Apply, the WEP Key values are displayed as zeros for security reasons.
The default WEP key is the first key.
NOTE:
All units in the same cell should use the same key.
Advanced Tab
The Advanced tab provides additional performance parameters.

!
CW Min/Max
- The size of the contention window. The contention window backoff algorithm is a method used to resolve contention between different stations trying to access the medium. The valid range is from 7 to 1023.
Defaults are 31 for CW Min and 1023 for CW Max.
!
RTS Threshold
- The minimum packet size required for an RTS
(Request to Send) to be sent. For packets with a size below the RTS
Threshold value, an RTS is not sent and the data packet is transmitted directly to the WLAN.
!
Short Retry Limit
- The maximum number of transmission attempts for a frame that is shorter than or equal to the RTS
Threshold. The default value is 8.
!
Long Retry Limit
- The maximum number of transmission attempts for a frame that is longer than the RTS Threshold. The default value is 4.
!
Basic Rate
- The maximum rate of multicast, broadcast and control frames transmissions. Multicast and broadcast transmissions are not acknowledged; therefore there is a chance that such transmissions will not be properly received without the possibility of using the acknowledgement mechanism for retransmission.
Therefore, it is recommended to use a lower rate for transmission of broadcast, multicast and control frames, to increase the probability that they will be received without errors. Enter the data rate at which broadcast, multicast and control frames are transmitted. The default value is 2 Mbps.
NOTE:
The Basic Rate parameter should be changed only if you are sure that all units in the cell can handle the defined rate. Use this parameter with caution, as it may bring the link down.
!
Power
– The transmit power level. The possible range is from –
12dBm to +24dBm.
