POI(Point Of Interface)As the core device of multi-network integration for indoor coverage, POI (Point Of Interface) uses multi-frequency low-loss combiner technology to carry out effective combination and division of uplink and downlink RF signals of operators, which can ensure that the system distortion-less combiner transmits uplink and downlink signals without interference among signals in each network, and different systems share an indoor distributed 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.
