Classification: CPC H | IPC H

Claim 15:
16. A method comprising:
scheduling transmission, from a first transceiver, of a first calibration signal at a first time-of-departure measured by a first clock of the first transceiver;
scheduling transmission, from the first transceiver, of a second calibration signal at a second time-of-departure measured by the first clock and succeeding transmission of the first calibration signal by an initial signal interval;
receiving, from a second transceiver, a first time-of-arrival measured by a second clock of the second transceiver, the first time-of-arrival corresponding to reception of the first calibration signal at the second transceiver;
receiving, from the second transceiver, a second time-of-arrival measured by the second clock, the second time-of-arrival corresponding to reception of the second calibration signal at the second transceiver; and
calculating a first frequency offset between the first clock and the second clock based on the first time-of-departure, the first time-of-arrival, the second time-of-departure and the second time-of-arrival.
