Abstract
An example mobile device includes a built-in communications component and a receiver. The receiver includes a first radio frequency (RF) antenna element that interfaces with a constructive interference formed by wireless RF power transmission waves emitted from a far-field transmitter. The first RF antenna element is configured to transform energy from the constructive interference into an alternating current (AC) voltage. The receiver also includes a rectifier configured to convert the AC voltage into a DC voltage. The receiver further includes a power converter configured to changed the DC voltage into a constant DC voltage to provide electrical energy to the mobile device. The receiver uses the communications component to transmit, to the far-field transmitter, communication signals containing status data indicating a power transmission effectiveness of the power transmission waves. The mobile device also utilizes the communications component to communicate with electronic devices other than the far-field transmitter.
