Concept Guide

Parameter Description
ARM/WIDS Override If enabled, this option disables Adaptive Radio Management (ARM) and
Wireless IDS functions and slightly increases packet processing
performance. If a radio is configured to operate in Air Monitor mode, then
the ARM/WIDS override functions are always enabled, regardless of
whether or not this check box is selected.
Reduce Cell Size (Rx
Sensitivity)
The cell size reduction feature allows you manage dense deployments and
to increase overall system performance and capacity by shrinking an AP’s
receive coverage area, thereby minimizing co-channel interference and
optimizing channel reuse. The possible range of values for this feature is 0-
55 dB. The default 0 dB reduction allows the radio to retain its current
default Rx sensitivity value.
Adaptive Radio
Management (ARM) Profile
Name of an Adaptive Radio Management profile associated with this
802.11a profile.
High-throughput Radio
Profile
Name of a High Throughput Radio profile associated with this 802.11a
profile.
Maximum Distance Maximum distance between a client and an AP or between a mesh point
and a mesh portal, in meters. This value is used to derive ACK and CTS
timeout times. A value of 0 specifies default settings for this parameter,
where timeouts are only modified for outdoor mesh radios which use a
distance of 16km..
Spectrum Monitoring If enabled, the AP operates as a hybrid AP that can simultaneously serve
clients and monitor a single channel for spectrum analysis data.
