Claim 17:
18. The method of claim 16, further comprising:
receiving, from a third transceiver, a third time-of-arrival measured by a third clock of the third transceiver, the third time-of-arrival corresponding to reception of the first calibration signal at the third transceiver;
receiving, from the third transceiver, a fourth time-of-arrival measured by the third clock, the fourth time-of-arrival corresponding to reception of the second calibration signal at the third transceiver;
defining a third calibration point in a second set of calibration points, the third calibration point representing the first time-of-departure and the third time-of-arrival;
defining a fourth calibration point in the second set of calibration points, the fourth calibration point representing the second time-of-departure and the fourth time-of-arrival; and
calculating a second frequency offset between the first clock and the third clock based on the second set of calibration points.
