1. A wireless transceiver, comprising:
an access point (AP) configured to wirelessly communicate with at least one Wi-Fi user equipment (UE) and monitor a target band for energy signatures of a radio frequency (RF) operation within the target band; and
a dynamic frequency selection (DFS) unit configured to (i) receive a detected energy signature from the target band, (ii) obtain a location of the AP, (iii) perform a matching search for a known RF operation corresponding to the detected energy signature within a vicinity of the location of the AP, (iv) determine from the matching search that the detected energy signature does not correspond to a known RF operation within the vicinity of the AP and represents a false positive, and (v) cause the AP to operate on a communication channel within the target band, based on the determination, without switching to a different channel.
