Hi Friend,

RRM's coverage hole detection feature can alert you to the need for an additional (or relocated) lightweight access point.

If clients on a lightweight access point are detected at signal-to-noise ratio (SNR) levels that are lower than the thresholds specified in the Auto RF configuration, the access point sends a "coverage hole" alert to the controller.

The alert indicates the existence of an area where clients are continually experiencing poor signal coverage, without having a viable access point to which to roam.

You can look up the historical record of access points to see if these alerts are chronic, indicating the existence of a persistent coverage hole as opposed to an isolated problem.

Also have a look at this link to rwd more about RRM
