1. ) An apparatus to determine flight time and to compute the distance/location, comprising:
- a transmitter to transmit a signal to be used to determine the flight time and the corresponding distance/location in a transmission medium;
a receiver to receive the signal to be used to determine the flight time and a corresponding distance/location;
wherein the distance/location is determined by using the propagation properties of the transmission medium.

Abstract
A system and method establishes the time of flight and thereby distance between two transceivers on various media, including but not limited to vacuum, air, electrical wire, optical fiber; using carrier waves sent from one or more transmitters or transceivers to one or more receivers or transceivers. Carriers are arranged to allow the extraction of channel information and maintain acceptable peak to average ratios in an OFDM system.
