Field Description
Rates
Configuration
For each of the data rates listed, select whether the
rate is Basic, Optional, or Disabled.
When configuring the data rates, you should
consider the data rate capabilities of the wireless
devices in your enterprise.

 Basic – The Basic data rates are usually the data
rates that the vast majority of your wireless
devices can support. Only wireless devices that
support all the Basic data rates will be connected
to the WLAN system. Therefore, it is
recommended that you configure a minimal
number of Basic data rates that the vast majority
or all your wireless devices can support. When
working in Mixed Mode, there should be at least
one Basic data rate from the 802.11b rates.

 Optional – If you configure a data rate as
Optional, the network will provide that data rate
to wireless devices that can support it.


 Disabled – Disabled data rates are not available
to wireless devices.

Since the Extricom WLAN system allows
for dense deployment of APs it is
recommended where applicable, to
disable low data rates. Not doing so could
possibly lead to an “edge user” effect, in
which a client reduces aggregate network
throughput by moving to the edge of the
coverage area.
Short Preamble: This option becomes available only when selecting
802.11b as the WLAN mode. In this case, mark the
checkbox to allow a short preamble.
