Abstract
A multicarrier phase ranging system and method are provided. Generally, the method includes performing a handshake between first and a second transceiver to negotiate a list of channels and a start-time for a multicarrier phase ranging process. The process includes in a first cycle exchanging a Constant Tone (CT) between the first and second transceiver in a first epoch on a first channel, and processing the CT received in the first and second transceiver to measure a difference in phase between the CT received and a reference signal. The CT received is checked for interference using software or hardware in either or both of the first and second transceiver. If no interference is detected the first and second transceiver switch to another channel and exchange the CT at a next epoch. If interference is detected, at least one channel is skipped for at least a subsequent epoch.
