A method for generating a geofence includes receiving, at an automated frequency coordination (AFC) system, a geofence request from an AFC device where the geofence request requests to use a licensed radio frequency band and includes one or more operating parameters for the AFC device. The method also includes determining, by the AFC system, whether any of the one or more operating parameters interfere with any licensed devices on the licensed radio frequency band. When none of the one or more operating parameters interfere with any of the licensed devices on the licensed frequency band, the method further includes generating, by the AFC system, based on the one or more operating parameters, a geofence defining an operating boundary for the AFC device to communicate within. The method also includes communicating, from the AFC system to the AFC device, a response to the geofence request where the response includes the geofence.

Reverse geofence feature in an automated frequency coordination system

An environmental frequency sensing device, includes logic that performs signal strength (SS) level separation on a received band of frequencies to produce SS level separated frequencies. The logic performs frequency grouping on the SS level separated frequencies for each signal strength level to produce magnitude information for each grouping. The logic generates peak data by detecting peaks of the produced magnitude information. The logic generates an edge event indicating a signal edge based on arrival or departure of a given peak and compares, on a frequency basis, generated edges to stored fingerprint data of a signal of interest. Based on the comparison, the logic provides detected signal data indicating current use of a range of frequencies in an environment.
