1. A method comprising:
communicating a plurality of headerless packets, respectively including scrambled timestamp sequence (STS) packets but not including encoding headers, between respective communication circuits;
assessing a time of flight (TOF) value indicative of time elapsed between transmission and reception of the plurality of headerless packets based on the STS packets; and
determining a distance between the communication circuits based on the assessed time of flight.
