1. A method for locating a reverse-beacon in a detection field comprising:

  • providing a reverse-beacon comprising a transceiver and a computer in communication with said transceiver;

    providing a plurality of system nodes deployed to form a detection field;

    moving said reverse-beacon into said detection field;

    receiving at said reverse-beacon, first system node signals from a first system node in said plurality of system nodes at said transceiver;

    receiving at said reverse-beacon, second system node signals from a second system node in said plurality of system nodes at said transceiver;

    receiving at said reverse-beacon, third system node signals from a third system node in said plurality of system nodes at said transceiver;

    converting at said computer said first system node signals, said second system node signals, and said third system node signals to a historical dataset comprising;

    a first system node identifier and a first system node distance associated with said first system node; and

    a second system node identifier and a second system node distance associated with said second system node;

    a third system node identifier and a third system node distance associated with said third system node;

    repeating said receiving first system node signals, said receiving second system node signals, said receiving third system node signals, and said converting a plurality of times to form a plurality of said historical datasets;

    determining at said computer a location of said reverse-beacon relative to said detection field, based upon comparing each of said historical datasets in said plurality of historical datasets to calculate a location of said reverse-beacon within said detection field.
