Abstract
Certain embodiments disclosed herein include a circuit for generating modulated backscattered sensory data. The circuit includes a sensor configured to produce sensory data in a format of a bitstream; a waveformer configured to generate a waveform signal (m(t)) compliant with a wireless protocol; a backscatter mixer configured to modulate each bit in the bitstream using the waveform signal; and a wakeup trigger configured to trigger the backscatter mixer in response to a reception of a packet from a first wireless device, wherein the modulated backscattered bitstream is being transmitted to a second wireless device.
