Patent ID: 8145247

Claim:
A server, comprising: a radio receiver coupled to receive a radio frequency (RF) signal at a time T 1 ; a clock interface to receive a reference clock signal; a network interface to couple the server to a base station via a computer network, the network interface configured to receive a time T 2 from the base station, the time T 2 representative of a time that the RF signal was received at the base station; and a processing device coupled to the radio receiver, the clock interface and the network interface, wherein the processing device is configured to use the time T 1 to determine a time T 0 when the RF signal was transmitted and a location of the base station, and wherein the processing device is configured to calculate a clock offset value based on when the RF signal was transmitted, the location of the base station, the time T 2 , and a reference clock signal, the clock offset value representative of a time to delay a local clock signal at the base station to synchronize the local clock signal at the base station with the reference clock signal.
