Patent ID: 8018950

Claim:
A method of distributing a global clock to a plurality of networked devices connected over a converged network, comprising: acquiring a Global Positioning System (GPS) clock with a plurality of base transceiver stations at a GPS clock acquiring stage and each of said plurality of base transceiver stations deriving a global clock from said GPS clock; transmitting, over one or more wired connections, said global clocks from said plurality of base transceiver stations to a control stage having a plurality of controllers which control the base transceiver stations; distributing said global clocks from the control stage to a network access stage over the one or more wired connections, wherein devices within the control stage select a best clock for distribution to the network access stage, wherein the best clock is closest to an average of the global clocks measured over a period of time; and distributing the best global clock from said network access stage to all networked devices connected over the converged network, wherein devices within the network access stage select the best clock for distribution to the networked devices.
