Abstract
A method of wireless power transmission is performed at a wireless-power-transmitting device having one or more antennas configured to transmit wireless-power signals, one or more processors, and a wireless data transceiver. The method comprises detecting that a wireless-power-receiving device is located in proximity to the wireless-power-transmitting device; establishing a data-traffic profile associated with the wireless-power-receiving device, the data-traffic profile including identifications of data signals to be exchanged over a predetermined frequency band between the wireless-power-receiving device and the wireless-power-transmitting device using the wireless data transceiver, determining windows of time during which to transmit wireless-power signals over the predetermined frequency band to the wireless-power-receiving device based on the data-traffic profile; and at the determined windows of time, transmitting, by the one or more antennas, wireless-power signals over the predetermined frequency band to the wireless-power-receiving device.
