The RF management profiles configure radio tuning and calibration, AP load balancing, coverage hole
detection, and RSSI metrics.
802.11a Radio—Defines AP radio settings for the 5 GHz frequency band, including the Adaptive Radio
Management (ARM) profile and the high-throughput (802.11n) radio profile. Refer to
802.11a/g Radio" on
802.11g Radio—Defines AP radio settings for the 2.4 GHz frequency band, including the Adaptive
Radio Management (ARM) profile and the high-throughput (802.11n) radio profile. Each 802.11a and
802.11b radio profile includes a reference to an Adaptive Radio Management (ARM) profile. If you would
like the ARM feature to dynamically select the best channel and transmission power for the radio, verify
that the 802.11a/802.11g radio profile references an active and enabled ARM profile. If you want to
manually select a channel for each AP group, create separate 802.11a and 802.11g profiles for each AP
group and assign a different transmission channel for each profile. Refer to
Radio" on
ARM—Defines the Adaptive Radio Management (ARM) settings for scanning, acceptable coverage
levels, transmission power and noise thresholds. In most network environments, ARM does not need
any adjustments from its factory-configured settings. However, if you are using VoIP or have unusually
high security requirements you may want to manually adjust the ARM thresholds. Refer to
> 802.11a/g Radio > ARM" on
HT Radio—Manages high-throughput (802.11n) radio settings for 802.11n-capable APs. A high-
throughput profile determines 40 Mhz tolerance settings, and controls whether or not APs using this
profile will advertise intolerance of 40 MHz operation. (This option is disabled by default, allowing 40
MHz operation.) Refer to
Event Thresholds—Defines error event conditions, based on a customizable percentage of low-speed
frames, non-unicast frames, or fragmented, retry or error frames.

Optimization—Enables or disables load balancing based on a user-defined number of clients or degree
of AP utilization on an AP. Use this profile to detect coverage holes, radio interference and STA
association failures and configure Received signal strength indication (RSSI) metrics.

Profiles > RF > 802.11a/g Radio
The two 802.11a and 802.11g RF management profiles for an AP configure its 802.11a (5 Ghz) and 802.11b/g
(2.4 GHz) radio settings. Use these profile settings to determine the channel, beacon period, transmit
power, and ARM profile for a mesh AP's 5 GHz and 2.5 Ghz frequency bands. You can either use the
"default" version of each profile, or create a new 802.11a or 802.11g profile which you can then configure as
necessary. Each RF management profile also has a radio-enable parameter that allows you to enable or
disable the AP's ability to simultaneously carry WLAN client traffic and mesh-backhaul traffic on that radio.
Radios are enabled by default.
Perform these steps to create or edit radio profiles for 802.11a or g. This type of radio profile references
additional profiles such as ARM and High-throughput Radio profiles. You have the chance to add or edit
