Abstract:
1. A method for determining a path loss value between a receiver at a first location and a wireless mobile device at a second location, the receiver being one of a plurality of receivers where each receiver is sited at a location different from the other receivers and from the second location, comprising the steps of: geolocating the mobile device at the second location; and at the receiver, the receiver being at the first location: sending to a central node a first reference signal representative of the transmitted signal attribute; determining at the central node a primary receiver from the plurality of receivers and sending to the primary receiver a second reference signal representative of the first reference signal from the receiver at the first location; and determining from the received signal level of the first signal and from the second reference signal the path loss value between the primary receiver and the mobile device at the second location.
