Abstract
Clock synchronization for a wireless communication system is described. The communication system utilizes a server with a radio coupled to receive a radio frequency (RF) signal and a clock interface to receive a reference clock signal. The server includes a network interface configured to receive, from a base station, a time that the RF signal was received at the base station. The server further includes a processing device configured to determine when the RF signal was transmitted and a location of the base station, and configured to calculate 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.
