Point of Interface (POI), refers to the specific equipment located between multi-system base station signal source and indoor distribution system antenna feeder. It is equivalent to a combiner with higher performance, which combines downlink signals of the multi-system base station signal source and outputs it to the indoor distribution system, and at the same time, outputs uplink signal from the antenna feeder equipment to the source of each system in the opposite direction.
