In the Discovered RF Threat Stations table, the Sensor field indicates which access point is detecting the particular threat. Using the sensor ID and MAC address of the access point allows you to easily determine the location of the access point that is detecting the threat.
For this section in particular (and as a good habit in general), you might find it helpful to keep a record of the locations and MAC addresses of your access points.
Use the MAC address to find the physical location of the access point.
The RF threat is likely to be in the location that is served by this access point.
