A method of tracking objects in a wireless power delivery environment in which a wireless power delivery system and multiple power receiver clients are located, the method comprising: Receiving, by multiple adaptively-phased radio frequency antennas of the wireless power delivery system, sequential beacon signals transmitted by the multiple power receiver clients respectively in the wireless power delivery environment; measuring, by the wireless power delivery system, a phase of each received beacon signal at each of the multiple adaptively-phased radio frequency antennas; generating, by the wireless power delivery system, a phase pattern for each received beacon signal, wherein the phase pattern includes the measured phase of the received beacon signal at each of the multiple adaptively-phased radio frequency antennas; comparing the phase pattern to an expected phase pattern for each received beacon signal to identify phase differences, wherein the expected phase pattern includes an expected phase at which the beacon signal is expected to be received at each of the multiple adaptively-phased radio frequency antennas in the absence of non-static objects within the wireless power delivery environment; processing the phase differences to identify one or more non-static objects within the wireless power delivery environment, wherein the non-static objects do not transmit beacon signals to the wireless power delivery system; tracking movement data associated with the one or more non-static objects within the wireless power delivery environment based on a three-dimensional image of the wireless power delivery environment and the phase differences, wherein the three-dimensional image identifies shapes and relative locations of static objects within the wireless power delivery environment; aggregating the movement data associated with the one or more non-static objects within the wireless power delivery environment; and generating a motion-based map indicating the aggregated movement of the one or more non-static objects within the wireless power delivery environment, wherein the static objects are objects that do not move for a movement threshold, and the non-static objects are objects that exceed the movement threshold.
