ALLIANCE Multi-Carrier DAS Integrated BTS Interface Unit (iBIU)

The iBIU receives RF signals from, and sends RF signals to, the base station (BTS) or bi-directional amplifier (BDA). In the iBIU, each signal is independently filtered, attenuated and controlled. The optical modules in the iBIU convert the RF and optical signals and transmits them via fiber to and from the remote units (ROUs).

The iBIU can be configured with any combination of point-of-interface (POI) modules: high power (20W), low power (100mW), or hybrid (high and low power).

For deployments requiring support for more than 16 services per sector, the DAS headend can support a secondary iBIU that interfaces directly with the main iBIU.

The iBIU is compatible with all current ALLIANCE DAS REL6 remote units including low (1W, 2W), medium (5W) and high power (20W/40W) units.
