Claim 0:
1. A method in a wireless power transmission system (WPTS) in a radio frequency (RF) beacon signal receiving mode and situated in a wireless power delivery environment, the method comprising:
determining a background signature based at least in part on one or more characteristics of a plurality of RF signals sampled via at least one antenna of the WPTS in a first time period, wherein the background signature has a lower average power or amplitude as compared to an average power or amplitude of the plurality of RF signals;
extrapolating at least part of the background signature for use in a second time window occurring, at least in part, after the first time window;
receiving, via the at least one antenna of the WPTS, an RF beacon signal during the second time window;
in response to receiving the RF beacon signal, identifying a signature of the RF beacon signal; and
in response to identifying the signature of the RF beacon signal, transmitting, via the at least one antenna, one or more wireless power signals to a location of a transceiver device from which the RF beacon signal originated.
