Abstract: In an aspect, an asset tracking coordination component estimates a time of a beacon transmission from a wireless energy charging-capable device coupled to an asset within a threshold proximity of a scanning device based on an estimated distance between the asset tracking coordination device and the scanning device and timing information associated with a wireless energy transmission, and schedules a beacon scanning window for the scanning device to scan for the beacon transmission based on the estimated time. In a further aspect, a scanning device may both provide a wireless energy transmission and may also scan for beacon transmission(s) from wireless energy charging-capable device(s) during a beacon scanning window.
