Classification: CPC H  G | IPC G  H

Claim 13:
14. A method comprising:
receiving a plurality of measurement values of the locally-averaged signal strength of a radio signal as received at a plurality of measurement locations, wherein each of the plurality of measurement location is unique, and wherein the radio signal is characterized by a wavelength λ;
generating a plurality of candidate locations of a radio transmitter of the radio signal, wherein each of the plurality of candidate locations is unique;
generating a plurality of path loss estimates, wherein each of the plurality of path loss estimates is an estimate of the path loss for a hypothetical signal that propagates between a unique pair of:
(i) one of the plurality of candidate locations, and
(ii) one of the plurality of measurement locations,, wherein the hypothetical radio signal is characterized by the wavelength λ; and
generating an estimate of the location of the radio transmitter of the radio signal based on which of the plurality of candidate locations is most consistent with:
(i) the plurality of measurement values, and
(ii) the plurality of candidate predictions of total path loss.
