1. A method for enhancing the power efficiency of a first wireless device, the first wireless device including an energy receiver, the method comprising:
- receiving a transmitted signal at the first wireless device;
converting the transmitted signal into power through the energy receiver; and
providing the power to a component of the first wireless device,wherein a frequency of the energy receiver is set to substantially one of a transmission frequency of a transmitter of the first wireless device, a transmission frequency range center of a wireless communication standard, or a transmission frequency of a transmitter of a second wireless device obtained from information transmitted by the second wireless device to the first wireless device, andwherein the frequency of the energy receiver is set to match the transmission frequency range center of the wireless communication standard in response to determining that the transmitter of the first wireless device is not active.

11. A wireless device comprising:
-
at least one of an antenna and an electrical shield to receive a transmitted signal; an energy receiver to convert the transmitted signal into power and provide the power to a component of the wireless device; and a control circuit to set a frequency of the energy receiver to substantially one of a transmission frequency of a transmitter of the wireless device, a transmission frequency range center of a wireless communication standard, or a transmission frequency of a transmitter of an other wireless device obtained from information transmitted by the other wireless device to the wireless device, wherein the control circuit sets the frequency of the energy receiver to match the transmission frequency of the transmitter of the other wireless device in response to determining that a transmitter signal power of the transmitter of the other wireless device is greater than a transmitter signal power of the transmitter of the wireless device. - View Dependent Claims (12, 13, 14, 15, 16, 17)
