smart-rf

Displays Self-Monitoring At Run Time RF (Smart RF) statistical history to assess adjustments made to device configurations to compensate for detected coverage holes or device failures

When invoked by an administrator, Smart RF instructs access point radios to change to a specific channel and begin beaconing using the maximum available transmit power. Within a well-planned deployment, any RF Domain member access point radio should be reachable by at least one other radio. Smart RF records signals received from its neighbors as well as signals from external, un-managed radios. AP-to-AP distance is recorded in terms of signal attenuation. The information from external radios is used during channel assignment to minimize interference.

Supported on the following devices:

Determine whether power compensations were relegated to known device outages or if compensations were consistent over the course of a day or week.
