Abstract

A transmitter-side host device comprises a transmitter-side antenna and a transmitter-side control system. The transmitter-side control system is configured to: (i) output an unmodulated AC signal for driving the transmitter-side antenna to emit an unmodulated alternating electromagnetic field that delivers wireless power to a receiver-side host device that includes a load and (ii) modulate an in-band data signal onto the unmodulated AC signal and thereby outputting a modulated AC signal for driving the transmitter-side antenna to emit a modulated alternating electromagnetic field that delivers both wireless power and wireless data to the receiver-side host device. The in-band data signal is formatted in accordance with a wireless power and data transfer protocol and carries, as payload, embedded data originating from the transmitter-side host device that is formatted in accordance with a data communication protocol different from the wireless power and data transfer protocol.
