Tour: SOLiD DAS at Hyatt Regency Bellevue

We recently co-hosted a tour of theĀ SOLiD Technologies Distributed Antenna System (DAS) at the Hyatt Regency Bellevue with RCR Wireless during RCR Wireless Global Tour Conference Series stop in Bellevue, WA.

Wireless carriers, integrators, building owners and public safety officials joined us to get a first-hand look at how an in-building wireless system works.

The SOLiD DAS, which provides coverage for Sprint as well as public safety for the Bellevue Fire Department across more that 700,000 square feet at the hotel, was installed by integrator TriPower.

How The SOLiD DAS Works

Wireless carrier and public safety signals are received via a rooftop antenna or, for larger deployments, from carrier base stations placed on-site.

RF signals are routed to the BIU (Base Station Interface) where advanced RF filtering eliminates potential interference between signal types. RF Power Control guarentees each wireless carrier will receive proper RF power on the DAS.

Al RF signals are converted to optical signals and transported over one strand of fiber to each designated telecom closet.

An ROU (Remote Optical Unit) is installed in designated telecom closets to convert optical signals back to RF signals. These units are secure, water-tight and rugged – designed to work in harsh environments to support public safety requirements.

The RF signals are distributed over passive coaxial infrastructure and carefully placed broadband antennas.
