Profiles > RF > 802.11a/g Radio > AM Scanning
Air Monitor (AM) devices establish and monitor RF activity on the network. This profile depends on the
controller having a minimum version of 6.0.0.0.
Perform these steps to create or edit an Air Monitor Scanning profile.
1. Select Profiles > RF > 802.11a/g Radio > AM Scanning in the navigation pane.
2. Select the Add button to create a new AM Scanning profile, or click the pencil icon to edit an existing profile.
Complete the settings as described in Table 52:
Profiles > RF > 802.11a/g Radio > ARM
Each 802.11a and 802.11g radio profile references an Adaptive Radio Management (ARM) profile. When you
assign an active ARM profile to a mesh radio, ARM's automatic power-assignment and channel-assignment
features will automatically select the radio channel with the least amount of interference for each mesh portal,
maximizing end user performance. In earlier versions of this software, an AP with a mesh radio received its beacon
period, transmission power and 11a/11g portal channel settings from its mesh radio profile. Mesh-access AP
portals now inherit these radio settings from their dot11a or dot11g radio profiles.
Each ARM-enabled mesh portal monitors defined thresholds for interference, noise, errors, rogue APs and radar
settings, then calculates interference and coverage values and selects the best channel for its radio band(s). The
mesh portal communicates its channel selection to its mesh points via Channel Switch Announcements (CSAs),
and the mesh points will change their channel to match their mesh portal. Although channel settings can still be
defined for a mesh point via that mesh point's 802.11a and 802.11g radio profiles, these settings will be overridden
by any channel changes from the mesh portal. A mesh point will take the same channel setting as its mesh portal,
regardless of its associated clients. If you want to manually assign channels to mesh portals or mesh points, disable
the ARM profile associated with the 802.11a or 802.11g radio profile by setting the ARM profile’s assignment
parameter to disable. The ARM power adjustment feature does not apply to all ARM-enabled Mesh portals.
