Abstract
In one embodiment, the disclosure relates to 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 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; (iii) receiving at said receiver the signal transmitted from said wireless device on said first frequency channel; (iv) receiving at said receiver an indication of transmission signal strength of said signal; (v) measuring at said receiver the received signal strength of said signal; 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.
