System for coordination of TDD transmission bursts within and between cells in a wireless access system and method of operation

摘要

There is disclosed, for use in a first radio frequency (RF) modem shelf associated with a first one of a plurality of base stations in a fixed wireless access network, a timing distribution apparatus for synchronizing the operations of a plurality of RF modems in the first RF modem shelf. The timing distribution apparatus comprises: a) a primary master clock source for generating an internal master clock signal and an internal master framing signal; b) a plurality of interface control processors, each of the interface control processors receiving the internal master clock signal and the internal master framing signal and using the internal master clock signal and the internal master framing signal to synchronize a downlink transmission of one of the plurality of RF modems; c) a synchronization bus for distributing the internal master clock signal and the internal master framing signal from the primary master clock source to the plurality of interface control processors; d) an external interface input port for receiving at least one external master synchronization signal from a second RF modem shelf in the fixed wireless access network; and e) an external interface output port for receiving at least one of the internal master clock signal and the internal master framing signal from the primary master clock source and transmitting the at least one of the internal master clock signal and the internal master framing signal to the second RF modem shelf.
