Abstract
A method and apparatus for Time Division Duplex (TDD) synchronization of Access Points (APEs) uses the 1 pulse-per-second timing pulses of the Global Positioning System (GPS) and synchronization state machines for its Time Division Multiple Access (TDMA) structure. As a result, the present invention obviates the need for expensive voltage-controlled oscillators used by the prior art, and achieves stable timing accuracy within approximately 7.5 minutes, as opposed to the 12 to 24-hour period needed by prior art methods.
