Abstract

A communications device synchronizes itself with respect to an external reference signal e.g. a GPS signal. The communications device detects timing reference signals e.g. beacon signals from a communications network. If the communications device determines that the network is not synchronized to the external timing reference signal the communications device operates as a master timing control device. In various embodiments when operating as a master timing control device the wireless communications device communicates time stamps e.g. in beacon signals which indicate a greater passage of time than the actual passage of time. When operating as a master timing control device the communications device transmits network timing reference signals at a higher rate than is being used by the network to seize control of network timing and become the master timing control device. The communications device drives the network timing to synchronize network timing to the external timing reference.
