1. A method of dynamically managing frequency hopping in a wireless communication network comprising a controller, a plurality of base stations, a local area network interconnecting said base stations with said controller, and a plurality of mobile stations, each said mobile station and base station including a transceiver for wireless bidirectional communication therebetween when in sufficient proximity to each other, said method comprising the steps of:

  • (a) requesting by a given base station a frequency hopping pattern assignment from said controller;

    (b) monitoring by said given base station the frequency hopping pattern of the other ones of said plurality of base stations;

    (c) requesting by said given base station a new frequency hopping pattern if another one of said plurality of base stations is using the same frequency hopping pattern as said given base station;

    (d) beginning frequency hopping by said given base station;

    (e) monitoring by said given base station interference relative to the assigned frequency hopping pattern;

    (f) determining by said given base station if frequency hopping pattern revision is necessary as the result of the monitoring of interferences; and

    (g) returning to step (b) if revision is necessary, and if revision is not necessary, continuing to hop with the same frequency hopping pattern.
