Method and apparatus for determining a distance between a base station and a mobile unit
First Claim
1. A method for detecting at least one repeater between a base station and a mobile unit, comprising:
- determining a first estimate of a distance traveled by a signal on a wireless communication link between the base station and the mobile unit;
determining a second estimate of the distance traveled by the signal on the wireless communication link between the base station and the mobile unit;
comparing the first and second estimates; and
determining whether the signal was processed by the at least one repeater based upon comparing the first and second estimates.
