1. In a wireless communication system having plural base stations defining a signal coverage area for communication with a mobile-appliance located within the coverage area, a method of determining the position within the coverage area of mobile-appliance location determining sensors, comprising the steps of:

  • (a) determining for each of the plural base stations the capability to receive signals from a mobile appliance;

    (b) estimating the transmit power level of the mobile appliance at a selected geographic point in the coverage area;

    (c) estimating for each of the plural base stations, the strength of a signal from the mobile-appliance transmitted at the estimated power level from the selected geographic point;

    (d) identifying each of the plural base stations estimated to receive a signal above a predetermined threshold from the mobile-appliance;

    (e) estimating the accuracy of a calculated position of the mobile-appliance from the estimate of the signal strength received at the identified base stations; and

    (f) determining the position of mobile-appliance location determining sensors in the coverage area needed to provide the estimated location determining accuracy within a predetermined threshold.
