1. A computer-implemented method for radio frequency assignment within a network of base stations, the method comprising:
in response to receiving information that a base station from the network of base stations has relocated, obtaining data encoding a geographic position of the relocated base station;
accessing a database storing data encoding geographic positions of base stations from the network of base stations, and respective radio frequency assignment information for each base station;
analyzing an interference pattern between the base station that has relocated and other base stations from the network that are within a threshold distance of the relocated base station, wherein the analyzing comprises:
simulating the interference pattern when assigning the relocated base station a candidate radio frequency based on the geographic position of the relocated base station, and
computing a coverage of the relocated base station relative to the other base stations from the network that are within a threshold distance of the relocated base station;
determining the radio frequency assignment for the relocated base station based on the interference pattern; and
in response to the interference pattern falling below a first threshold level and the coverage exceeding a second threshold level, allocating the candidate radio frequency to the relocated base station.
