ALLIANCE Multi-Operator DAS Enhanced BTS Interface Unit (eBIU)

Enhanced Base Station Interface Unit with Integrated Point of Interface (POI)

ALLIANCE is a multi-operator DAS solution for commercial wireless services. The Enhanced BIU with integrated POI is compatible with all of SOLiD’s current and legacy low, medium and high power remote units.

Modular design means lower operational costs and unparalleled RF performance, cost efficiency and flexibility.

Rugged construction meets the latest fire codes and requirements for harsh environmental conditions.

* Integrated low and high power Point of Interface (POI) modules which can be mixed or matched in a single chassis

* Accepts simplex or duplex feeds from carrier equipment

* Reduced footprint: 16 services in 4RU

* Integrated AC or DC power supply module

* 4.3-10 connectors

* Multiple frequency bands in a single unit

* Software configurable uplink and downlink paths for each service

* Auto Level Control (ALC) uplink and downlink for each service

The eBIU receives downlink signals from the base station (BTS) or bi-directional amplifier (BDA). Each signal is then independently monitored, filtered and controlled automatically in the eBIU and transmitted to the system’s ODUs (Optic Distribution Units). The ODU converts the RF signals to optical signals and transmits them via fiber to the remote units (ROUs).

At the ROU, signals are amplified and sent via coax to the remote antennas placed throughout the building or campus. For the uplink path, the process is reversed allowing the eBIU to route each frequency to the proper operator.

The eBIU can be configured with high power (20W) or low power (100mW) Point of Interface (POI) modules or high/low modules can be mixed in the same chassis. The high power POI has an input range from +15dBm to +43dBm and the low power from -10dBm to +20dBm. All POI modules offer both duplex and simplex ports for connectivity with carrier equipment.

A fan tray draws air across cooling fins on the modules when using high power POIs. SOLiD recommends leaving 1U of space above and below the unit to dissipate heat when using the high power POIs.

For deployments requiring more than 16 services per sector, a second eBIU, configured as a secondary (or slave) unit, can be connected to the primary eBIU via the eMCDU module.

The eBIU mounts in a 19-inch equipment rack and is powered by an internal AC or DC power supply. Supported bands include: 700MHz, 800MHz, 850MHz, 1900MHz, 2100MHz (AWS 1+3), 2.3GHz WCS, 2.5GHz.
