Classification: CPC H  G | IPC G  H

Claim 6:
7. The method of claim 1:
further comprising:
for each transceiver in the set of transceivers:
receiving a calibration signal:
transmitted from a calibration device at a known distance from the transceiver; and
comprising a calibration subcarrier signal for each subcarrier frequency in the set of subcarrier frequencies;

for each subcarrier frequency in the set of subcarrier frequencies:
calculating a target calibration phase difference between the calibration subcarrier signal for the subcarrier frequency and a subcarrier reference signal for the subcarrier frequency based on the known distance; for each transceiver in the set of transceivers;
calculating a calibration phase difference between the calibration subcarrier signal for the subcarrier frequency and the subcarrier reference signal for the subcarrier frequency; and
calculating a frequency-dependent phase offset for the subcarrier frequency in a set of frequency-dependent phase offsets based on a difference between the target calibration phase difference and the calibration phase difference; and

wherein computing the phase offset based on the subcarrier frequency and the calibration function comprises:
generating a calibration function for the transceiver based on the set of frequency-dependent phase offsets; and
computing the phase offset based on the subcarrier frequency and the calibration function.
