POI (Point of Interface) is a passive device which combines multiple signal resources from multiple carriers and distributes to the DAS system.Serving as a powerful multi-combiner, POI is a comprehensive and reliable passive component to signal integration and transmission. Due to different operators provide respective frequency range to their customers, while customers will interact freely with persons despite frequency boundaries, there should be a smart system to accommodate mobile communication as much as possible – this is what POI works for. Partnered with repeater equipment, it can be tailored to frequency interfaces without operator limits, meanwhile transmit combined and stable signal to floors, building, etc.It is applicable to mobile communications, private trunking communications, telecommunications access network and other systems such as LTE TDD, LTE FDD, TD-SCDMA, CDMA, GSM, DCS, WCDMA (UMTS), WLAN, etc.
