■ In order to avoid interference, POI is divided into two platforms, which transmit the uplink and downlink signals separately.POI serves as a bridge connecting the wireless communication donor signal and the distributed coverage signal (leakage cable and antenna array, etc.).
■ Mainly used for subway, exhibition center, exhibition hall, airport and other large buildings indoor coverage.In this system, the frequency combiner and bridge combiner are used to combine the mobile signals of multiple operators and various systems, and then the antenna feed distribution system is introduced to make full use of the resources and save the investment.
