1. A method for mapping system wide frequency interference among a plurality of cell sites of a wireless communication system using a phantom frequency, the method comprising:

  • selecting a frequency to be used as the phantom frequency;

    designating a cell site of the plurality of cell sites to be a phantom site;

    activating the phantom frequency at the phantom site;

    measuring a phantom signal strength at each of a plurality of phantom neighboring cell sites;

    recording the signal strengths at the phantom site and each of the plurality of neighboring phantom sites;

    redesignating another of the plurality of cell sites to be the phantom site;

    repeating the activating, measuring, recording and redesignating steps until each of the plurality of cell sites has been designated as the phantom site in turn; and

    compiling an interference mapping matrix as between the recorded signal strengths of each of the plurality cell sites and the phantom site.
