CTIA Super Mobility, Las Vegas—September 7, 2016—SOLiD, a wireless infrastructure company, announced today the debut of the ALLIANCE eBIU (Enhanced BTS Interface Unit), an enhancement to the company’s industry-leading multi-carrier head-end equipment, the ALLIANCE BIU. The new ALLIANCE eBIU makes more efficient use of rack space, increases design flexibility and ease of installation, and reduces the total cost of ownership.

The ALLIANCE eBIU drives down the overall cost of DAS network design by eliminating external hardware and increasing power inputs. ALLIANCE eBIU now accepts the most RF inputs per rack unit on the market. Up to 16 services are supported at maximum 20 watts per port within a head-end chassis that takes up only four RUs of rack space.

The ALLIANCE eBIU has been redesigned in a more compact form factor that takes up less space in the head-end. An integrated POI (point of interface) eliminates the need for separate hardware for power attenuation or conditioning. Together, these design changes reduce required rack space by 60% and de-clutter cabling.

“To address the needs of the evolving DAS market, in-building wireless networks must be easy to install and cost effective,” said Ken Sandfeld, president of SOLiD Americas. “With this innovation, SOLiD has raised the bar for DAS head-end equipment, streamlining installation, increasing flexibility and reducing overall costs for in-building networks.”

The ALLIANCE eBIU’s streamlined, integrated design makes it easier to set up and troubleshoot, and more adaptable to the needs of carriers, integrators, VARs and property owners. For maximum flexibility, the eBIU now offers expanded power input handling. It can be configured with high power POI (up to 20W) or low power POI (up to 100mW) 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.

The integrated POI modules are fitted with 4.3-10 connectors for best PIM performance and increased testing efficiency. A low power duplex POI is designed specifically for the rising demand for Small Cell signal sources.

The ALLIANCE eBIU supports all carriers in a single chassis, with seven frequency bands, including the new 2300 MHz (WCS) and 2.5 GHz bands, as well as the established 700, 800, 850, 1900 and 2100 frequencies.

The ALLIANCE eBIU with integrated POI is compatible with SOLiD’s flexible array of 1-watt, 2-watt, 5-watt, and 20-watt remote units. Its modular design allows simple firmware upgrades, translates into lower operational costs and delivers unparalleled RF performance, cost efficiency and flexibility.

Additional ALLIANCE eBIU features include:

  •     A low-loss POI option for fiber backhaul to remote BTS locations that maintains healthy SNR
  •     Integrated AC or DC power supply that saves 1 RU on crowded racks
  •     Alarms for monitoring are configurable to either an input or output
  •     Integrated combiner for cascaded BIU scalability eliminates the need for an external combiner and cuts down on cabling

The ALLIANCE eBIU is available now. For further information, please visit SOLiD at http://
