Abstract

A method for determining a path loss value of a signal transmitted from a wireless device to a receiver in a wireless communication system having at least one cell having at least one sector operating on at least one frequency channel. The method includes: (i) identifying a geographic area where the path loss value is to be determined; (ii) 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; at the receiver (iii) receiving the signal transmitted from the wireless device on said first frequency channel; (iv) receiving an indication of transmission signal strength; (v) measuring the received signal strength; and (vi) 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.
