This paper presents our most ambitious backscatter measurement to date. Drawing microWatts of power at an 5.8 GHz RF tag, a signal is backscattered in free space from the 10th floor of Viewpoint condominium tower to a reader atop ECE’s Van Leer building. This link uses our custom tunnel diode reflection circuitry to achieve a range of 1.2 kilometers.
