1. A method for determining a path loss value of a signal transmitted from a wireless device and received by a receiver, where the wireless device and the receiver operate within a wireless communication system having at least one cell having at least one sector operating on at least one frequency channel, the method comprising the steps of:

  • identifying a geographic area where the path loss value is to be determined;

    identifying a first cell, a first sector, and a first frequency channel associated with the geographic area wherein said wireless device is actively communicating with said receiver using said first frequency channel without disabling any other communication channel;

    receiving at said receiver the signal transmitted from said wireless device on said first frequency channel;

    receiving at said receiver an indication of transmission signal strength of said signal;

    measuring at said receiver the received signal strength of said signal; and

    determining the path loss value of said first frequency channel as a function of the indication of transmission signal strength and the received signal strength.
