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 capable of synchronizing a downlink transmission of one of the plurality of RF modems; c) a synchronization bus; d) an external interface input port capable of receiving an external master synchronization signal from a second RE modem shelf; and e) an external interface output port for transmitting at least one of the internal master clock signal and the internal master framing signal to the second RF modem shelf.
