The construction of 5G networks requires a large number of split base station devices (BBU + RRU), and the centralized deployment of BBUs has become a trend. A single equipment room needs to support the synchronization of dozens or even more sets of BBU devices. At this time, how to save the investment in synchronization antennas and feeders,and reduce the difficulty of site selection for BBU equipment rooms or synchronization antennas has become an urgent problem to be solved. The Satellite Synchronous Signal Distributed Repeater can amplify and extend the synchronous signal and distribute it to multiple sets of BBUs, which can perfectly solve the above problems.
