"WebThe CPRI protocol is a full duplex serial data stream. In other words there is a transmit fiber and a receive fiber. It is also a synchronous protocol, which means the baseband must establish sync with the remote radio before communication can be established. One CPRI stream can support several IQ data flows to several different radios. " - Cpri iq
