ABSTRACT:
Radio frequency identification devices, backscatter communication device wake-up methods, communication device wake-up methods and a radio frequency identification device wake-up method are described. In one aspect, a wireless communication device includes a processor configured to process a plurality of received wireless signals and to control the communication of a plurality of outputted wireless signals, wherein the processor is configured to control the communication of the outputted wireless signals using backscatter modulation, circuitry coupled with the processor and configured to control operations of the processor, and wherein the processor is configured to output a reference signal responsive to detection of radio frequency energy, the circuitry is configured to analyze the reference signal and the radio frequency energy, and the processor is configured to enter a predefined mode of operation utilizing an increased amount of electrical energy responsive to the analysis of the reference signal and the radio frequency energy by the circuitry.
