Devices, systems and processes for identifying and detecting an interfering signal are described. A process may include conducting a scan of one or more frequency bands to obtain at least one scan result and determining therefrom if a response condition has been detected. If so detected, a first frequency band corresponding to the detected response condition may be identified and a response condition action to be performed determined. If no response condition action is to be performed, scanning continues. If a response condition is to be performed two or more available sensors are identified and a first sensor is selected. A scan plan is developed and then initiated by the first sensor. Data from the first sensor is received and analyzed to identify a second frequency band indicative of an interfering signal. Based on at least the scan data, a location for a signal interference source (SIS) may be estimated.

Determining a location of a user device comprises a wireless computing system supported by an access point. The wireless computing system receives a signal from the user device. The system estimates a location of the user device based on RSSI and calculates a boundary around the estimated location. The wireless computing system selects a plurality of sections inside of the boundary and performs a coarse calculation of a location of the user device based on an angle of arrival of the received signal. The system determines sections of the plurality of sections that have results from the coarse calculation that are more likely to be a location of the user device. The system performs a fine calculation of the location based on the angle of arrival of the received signal within each of the sections. The system identifies a particular section as the location of the user device.
