Active Point of Interface Units

The idDAS APOI is an Active Point of Interface used to connect various DAS feeders like BTSs (Base Transceiver Stations), Small Cells, or RRHs (Radio Remote Heads) and/or an Off-Air Repeater to the digital DAS system.

Up to 16 BTS sectors can be connected to each APOI shelf. Each APOI shelf consists of 8 plug in BTS interface modules (BTSI). Each BTSI covers one single band and supports up to 2 BTS ports. The supported services are: 800, 900, 1800, 2100, 2600 plus 700LTE, SMR 800 (Sprint), Cellular 850, 1900 and AWS. Each BTSI can be either un-duplexed (separate ports for TX/RX) or duplexed (single port for TX/RX) configuration, thus allowing different connections to different BTSs.
