Abstract
A mobile communication system, including: first and second nodes, wherein the first node includes: a first transmitter and a first receiver, and wherein the second node includes: a second receiver receiving a ranging signal from the first transmitter; a frequency synthesizer generating an internal signal in response to a sensing of the reception of the ranging signal; a digital circuit calculating a beat frequency by comparing the ranging signal to the internal signal and evaluating a time lapse from the reception of the ranging signal until the sensing of the reception of the ranging signal by using the beat frequency, wherein the time lapse is part of a response time of the second node; and a second transmitter providing the first receiver with the ranging signal that includes the response time of the second node.
