AP in a coverage area fails or becomes faulty, the administrator will need to replace the failed AP to
permanently remediate the problem.
With Interference Recovery, it is possible that the interfering APs are not owned or managed by the
company or division. In this case, Smart RF will adjust the channels and power values on the Smart RF
managed radios to provide the best possible RF environment around the interfering devices.
Interference Recovery
Smart RF provides mitigation from wireless sources of interference by measuring noise and interference
on the current channel of each Smart RF managed radio. When a noise threshold is exceeded, Smart RF
can select an alternative channel for the Smart RF managed radio with less interference. To avoid
channel flapping, a hold-timer is defined, which disables interference avoidance for a specific period of
time upon detection. Interference Recovery is enabled by default.

Neighbor Recovery
Smart RF provides automatic recovery for failed or faulty access points or faulty antennas by instructing
neighboring APs to increase their transmit power to compensate for the coverage loss. Using Smart RF
probes, each Smart RF-managed radio maintains an active list of neighboring Smart RF-managed
radios. The list includes each neighbors' channel, power, and attenuation. If a neighboring Smart RF
