  • Backscatter location tracking system and method
    Patent number: 11668810
    Abstract: A method for locating devices that transmit, backscatter or receive a wireless signal. The method comprising using each of one or more backscatter devices to modulate and backscatter a carrier signal transmitted by a transmitter. Modulating and backscattering the carrier signal generates a backscattered modulated signal comprising a sideband. The method further comprises receiving the one or more backscattered modulated signals with a receiver. At least one of the phase or amplitude of each sideband are used to determine at least one of: the distance between the transmitter and the backscatter device by which that sideband was generated, the distance between the receiver and the backscatter device by which that sideband was generated, and the sum thereof.
