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.

Claims

1-50. -50. (canceled)

51. A method of controlling a plurality of remote devices connected to a network, the plurality of remote devices comprising a first remote device comprising a backscattering transceiver, the method comprising:

at the first remote device, receiving a command from a master device over a backscattering communication channel;

sending the command from the first remote device to one or more of said plurality of remote devices over the network;

receiving information at the first remote device from one or more of said plurality of remote devices; and

transmitting the received information from the first device to the master device over the backscattering communication channel.

52. The method of claim 51, wherein the command is an activation command that selectively powers up particular remote devices of said plurality of remote devices.

53. The method of claim 51, wherein the information from one or more of said plurality of devices includes state information requested by the master device.

54. The method of claim 51, wherein the command includes configuration data for selectively configuring particular remote devices of said plurality of remote devices.

55. The method of claim 51, wherein the plurality of remote devices comprises an electronic system, wherein each remote device is a component of the electronic system and is independently controlled through commands from the master device.

56. The method of claim 51, wherein communications within the network is through a communication channel that is one of a Bluetooth, Zigbee, Wi-Fi, Infrared, and Ultra-Wideband wireless channel.

57. A method of controlling a first device by a second device, the first and second devices each comprising a backscattering transceiver, the method comprising:

detecting an incoming transmission at the second device from a third device through a cellular radio frequency channel;

generating a modulated command at the second device in response to detecting said incoming transmission from the third device; and

transmitting the modulated command to the first device through a backscattering channel.

58. The method of claim 57, wherein the third device is a software automated system.

59. The method of claim 57, wherein the second device is a back end processing system, wherein the third device is a cellular radio frequency front end device.

60. The method of claim 57, wherein the modulated command is for configuring the first device,

61. The method of claim 57, wherein the first device includes a power control element, wherein upon the execution of the command the power control element is activated and the first device transitions from a first power state to a second power state.
