Abstract
A method and system for providing power to a chargeable device via radio frequency link are provided. In one aspect, a method of providing power to a chargeable device via radio frequency link comprises generating a substantially unmodulated signal. The method further comprises radiating a substantially unmodulated radio frequency (RF) signal to the chargeable device via a transmit antenna based on the substantially unmodulated signal. The method further comprises powering or charging the chargeable device with power delivered by the substantially unmodulated RF signal.
