First Claim
1. A method of wirelessly controlling a device comprising:
- in a first electronic device, generating a first command;
modulating the first command; and
transmitting the modulated first command over a first communication channel using an RF signal;
in a second electronic device, receiving the RF signal over the first communication channel;
demodulating the modulated first command; and
executing the first command, wherein the second electronic device absorbs and uses at least some power from the RF signal transmitted by the first electronic device.

Abstract
Embodiments of the present invention include methods and systems for utilizing backscattering techniques in wireless applications. In one embodiment, the present invention includes a method of wirelessly controlling a device comprising, in a first electronic device, generating a first command, modulating the first command, and transmitting the modulated first command over a first communication channel using an RF signal. In a second electronic device, the RF signal is received over the first communication channel, and the modulated first command is demodulated and executed. In one embodiment, the second electronic device absorbs and uses at least some power from the RF signal transmitted by the first electronic device. In one embodiments, data generated by the second device may be transmitted back to the first electronic device using backscattering.
