ABSTRACT:
An exemplary method determines a location of a wireless mobile unit by a node in a communication network. Amplitude adjustment coefficients are received from a rake receiving process used by the mobile unit to receive an incoming signal. A path loss factor is computed based on the amplitude adjustment coefficients. A modified path loss value is calculated based on the path loss factor. The location of the mobile unit is determined based on the modified path loss value.
