1. Point Of Interface Multi Band Combiner 

Description Point of interface (POI) is a platform for multi-combining system for Base station and DAS It combines several mobile carriers(operators) BTS or DAS system two or four output port(Comport) for distributed antenna system. At the same time, it distributes the different uplink signals to their each system, realizing multi-band and multi-signal combination and using simple two or four Com Antenna ports This is a feasible and efficient measure of realizing the coverage by signals from multi-networks.
