Abstract
A method and apparatus is disclosed herein for controlling radio-frequency (RF) energy for wireless devices. In one embodiment, the method comprises determining to increase radio-frequency (RF) energy available to power a wireless tag and controlling the RF energy delivered to the wireless tag to provide tag energy, using one or more of: a) increasing transmission RF power of one or more wireless communication devices, b) increasing a duty cycle associated with wireless transmissions of one or more wireless communication devices, and c) decreasing path loss of the power to the wireless tag.
