System and methods of using electromagnetic waves to wirelessly deliver power to electronic devices

Abstract:

Wireless charging systems, and methods of use thereof, are disclosed herein. As an example, a method includes: (i) receiving, by a communications radio of a wireless power transmitter, a communication signal from a communications radio of a wireless power receiver, the communication signal including data used to determine a location of the wireless power receiver, and (ii) determining a location of the wireless power receiver based, at least in part, on the data included in the communication signal. The method further includes, in response to determining that the location of the wireless power receiver is within a wireless power transmission range defined by the transmitter, transmitting radio frequency (RF) power transmission waves towards the wireless power receiver, the RF power transmission waves converging to form controlled constructive interference patterns and destructive interference patterns in proximity to the location of the wireless power receiver.
