A Point of Interface (POI) is the critical backbone of any modern Distributed Antenna System (DAS). For multi-operator environments like airports and stadiums, Hefei BRI’s POI provides a seamless bridge between multiple Base Transceiver Stations (BTS) and the service antennas.

Our POI units are engineered to combine diverse frequency bands—ranging from 700MHz to 3500MHz—into a single distribution feed without signal degradation. By utilizing high-rejection filters and precision combiners, we ensure that signals from different carriers do not interfere with one another. This modular scalability allows infrastructure managers to add new operators or 5G bands with minimal disruption. Investing in a robust POI at the head-end ensures that your indoor wireless network remains future-proof, high-capacity, and reliable for thousands of simultaneous users.
