    activating the phantom frequency at the phantom site;

    receiving a first signal strength of the phantom frequency measured at a first mobile device located within the phantom site;

    receiving a second signal strength of the phantom frequency measured at a second mobile device located within a disparate cell site of the plurality of cell sites; and

    compiling an interference mapping matrix based in part on a ratio of the second signal strength to the first signal strength.
