Abstract
A method of synchronizing a base station and a remote station is presented. The base station is communicatively coupled with the remote station and a reference network. The base station clock signal is compared with a reference clock signal derived from the reference network and adjusted accordingly. The adjusted base station clock signal is then used to generate timing information in the form of a preamble, which is periodically transmitted from the base station over a wireless communication network to the remote station where a clock signal is generated. The remote station compares the clock signal with the timing information and adjusts the clock signal accordingly. This is done without reference to an external clock.
