Abstract:
1. A method comprising: correlating, by a network device, spectrum data received on a channel from a plurality of spectrum monitors, wherein the spectrum data from each spectrum monitor is characterized by timestamps, and at least one of radio frequencies and radio frequency (RF) source types associated with the plurality of timestamps; identifying, by the network device, a unique RF source, wherein identifying includes using respective spectrum data received from a subset of the plurality of spectrum monitors, wherein the respective spectrum data from each spectrum monitor in the subset of spectrum monitors shares an overlapping timestamp range, and at least one of an overlapping frequency range and an identical RF source type, wherein identifying the unique RF source further comprises identifying a presence of an interfering device and a classification corresponding to the interfering device; using triangulation to determine a location of the interfering device after correlating a set of fast Fourier transform (FFT) samples from the subset of spectrum monitors (1) that share an overlapping timestamp range and (2) that correspond to the same interfering device; and refining the location of the interfering device based on a known Effective Isotropically Radiated Power (EIRP) of the interfering device.
