Abstract
A method and system of integrated wireless power and data transmission in a wireless device having a data communication circuit for wireless data communication and a power reception circuit including a charge storage unit. The wireless device is tuned to receive wireless RF signals in a certain frequency band via an antenna. Switching between power reception mode and data communication mode is detected. Received RF signal electrical charge is selectively distributed to the power reception circuit and/or the data communication circuit based on the switching mode and/or strength of the RF signal.
