Abstract
A system includes diagnostic circuitry and a zone with one or more associated transceiver nodes. A first transceiver node broadcasts one or more beacons which a second transceiver node attempts to receive. The first transceiver node the second transceiver node or both being associated with the zone. The second transceiver node provides a reception indication to the diagnostic circuitry. Based on the reception indication, the diagnostic circuitry may generate a zone-specific radio signal fingerprint and apply the fingerprint to an input of a performance classification routine. Based on the output of the performance classification routine, the diagnostic circuitry may determine whether the zone-specific radio signal fingerprint for the zone has changed relative to one or more previous zone-specific radio signal fingerprints for the zone.
