MULTIPLE DATA SERVICES OVER A DISTRIBUTED ANTENNA SYSTEM

摘要

A method and system for supporting multiple time division duplexed (TDD) based wireless services or frequency division duplexed (FDD) wireless services on a Distributed Antenna System (DAS) is disclosed. The DAS can include a GPS receiver which can extract a timing signal (such as a 1 pps signal) from a GPS signal and distribute the timing signal to any component of the DAS to enable synchronization of the components for transmitting and receiving TDD signals. The GPS receiver can be part of the interface that connects a TDD based service to the DAS or separate component of the DAS. The DAS can distribute a reference clock signal to all of the components of the DAS in order to maintain zero frequency shift while manipulating with the carrier frequencies of the various wireless services carried by the DAS.
