Claim 11:
12. A wireless power transmission system (WPTS) for use in a wireless power delivery environment, the system comprising:
at least one antenna; and
a controller operably coupled to the at least one antenna, wherein the controller is configured to:
determine a background signature based at least in part on one or more characteristics of a plurality of radio frequency (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;
extrapolate at least part of the background signature for use in a second time window occurring, at least in part, after the first time window;
receive, via the at least one antenna of the WPTS, an RF beacon signal during the second time window;
in response to the RF beacon signal being received, identify a signature of the RF beacon signal; and
in response to the signature of the RF beacon signal being identified, direct the at least one antenna to transmit one or more wireless power signals to a location of a transceiver device from which the RF beacon signal originated.
