Claim Text:
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; displaying, by the network device, selected spectrum data on a map with a plurality of colors, wherein a respective color displayed at a respective location is based on a detection range of one of the plurality of spectrum monitors located closest to the respective location and indicates an ability of the closest spectrum monitor to detect a device located at the location with a radiated power or strength above a threshold; using triangulation to determine a location of an interfering device after correlating a set of fast Fourier transform (FFT) samples from the subset of spectrum monitors that share an overlapping timestamp range and 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.
