Abstract:
Embodiments of the present disclosure describe mechanisms for radio frequency (RF) ranging between pairs of radio units based on radio signals exchanged between units. An exemplary radio system may include a first radio unit, configured to transmit a first radio signal, and a second radio unit configured to receive the first radio signal, adjust a reference clock signal of the second radio unit based on the first radio signal, and transmit a second radio signal generated based on the adjusted reference clock signal. Such a radio system may further include a processing unit for determining a distance between the first and second radio units based on a phase difference between the first radio signal as transmitted by the first radio unit and the second radio signal as received at the first radio unit. Disclosed mechanisms may enable accurate RF ranging using low-cost, low-power radio units.

Claim (Index 12):
The radio system according to  claim 1 , wherein:\n the first radio unit is configured to perform a calibration to account for a phase shift within the first radio unit, or the second radio unit is configured to perform a calibration to account for a phase shift within the second radio unit.
