Optimize Data Rates: The Wireless LAN Array can optimize your 802.11a data rates automatically,
based on range or throughput. Click on the Range button to optimize data rates based on range, or click
on the Throughput button to optimize data rates based on throughput.
3
802.11a IAP Status: Click on the Enable 802.11a IAPs button to enable all 802.11a radios for this Array,
or click on the Disable 802.11a IAPs button to disable all 802.11a radios.
4
Channel Configuration: Click on the Auto Configure button to instruct the Array to determine the best
channel allocation settings for each 802.11a radio and select the channel automatically, based on
changes in the environment. This is the recommended method for 802.11a channel allocations.
5
Fragmentation Threshold: This is the maximum size for directed data packets transmitted over the
802.11a radio. Larger frames fragment into several packets, their maximum size defined by the value you
enter here. Smaller fragmentation numbers can hellp to "squeeze" packets through in noisy
environments. Enter the desired Fragmentation Threshold value in this field, between 256 and 2346).
6
RTS Threshold: The RTS (Request To Send) Threshold specifies the packet size. Packets larger than
the RTS threshold will use CTS/RTS prior to transmitting the packet—useful for larger packets to help
ensure the success of their transmission. Enter a value between 1 and 2347.
7
Click on the Apply button to apply the new settings to this session.
8
Click on the Save button to save your changes (otherwise your new settings will not take effect).
Global Settings .11bg
This page allows you to establish global 802.11b/g IAP (radio) settings. These settings include defining which
802.11b and 802.11g data rates are supported, enabling or disabling all 802.11b/g radios, auto-configuration of
channel allocations for all 802.11b/g radios, and specifying the fragmentation and RTS thresholds for all 802.11b/g
radios.
