SOLiD BARS Multi-Carrier DAS System

BARS is a multi-carrier hybrid DAS from SOLiD, built for commercial buildings that fall in the gap between a consumer signal booster and a full carrier-grade DAS. It is the right system when a single booster cannot cover the whole building, but the building does not need a full active DAS, the kind that runs almost seven figures, takes months to build, and needs sign-off from every carrier. Offices, schools, clinics, warehouses, big-box retail, and government buildings land in that gap all the time. How BARS works A rooftop donor antenna pulls in the cellular signal that already exists outside the building, where it is usually too weak to make it through the walls on its own. The SOLiD head-end takes that signal for up to three carriers at once and sends it deeper into the building over ordinary Cat6A network cable, the kind your IT team already runs, and power rides on that same line so each remote needs only one connection. Each remote unit amplifies the signal and feeds the distribution antennas that cover the space. Whether the design calls for slim bars, ceiling domes, or a mix, they put strong, reliable signal where people actually use their phones. The system delivers up to 100 dB of gain, and it works in both directions, so calls get out as reliably as they come in. The system grows with the building. A single head-end drives up to 40 remote units, hubs extend it over fiber where a building is large or spread out, and you can start with the coverage you need today and add remotes later without touching the original install. It goes in faster, and works sooner BARS runs on the network cabling your building already uses, so an install that a traditional DAS would stretch across months often comes together in a matter of days. It is FCC pre-approved under Part 20, which means no carrier approval process to wait on, no retransmission agreements, and no monthly carrier fees. It covers AT&T, T-Mobile, and Verizon at the same time, and it commissions itself the moment it powers on, so the building has working coverage almost right away. Your team manages it from a cloud portal or on-site, and it reports into the network monitoring tools you already run. Designed to disappear into the building The remote units are small, white, and unobtrusive, the kind of hardware that blends into a finished ceiling instead of drawing eyes in a lobby or a waiting room. For any space where tenants or customers will see the equipment, that matters more than a spec sheet lets on. Where BARS fits, and where it doesn't Here is the honest read. BARS is the right system for offices, schools, clinics and medical offices, warehouses, light manufacturing, big-box retail, and government facilities that need dependable coverage on every floor without a carrier-grade build. It is not designed for the traffic load of a large hospital or a packed stadium, where the capacity demands call for a full active DAS. If that is your building, we will tell you honestly and point you toward the right kind of system, even when it is not one we install. We carry every major manufacturer, so the recommendation you get is the one that fits your building, not the one with the best margin for us. Backed for the long haul SOLiD has engineered in-building wireless systems for more than 25 years, and BARS earned three 2025 Pipeline Innovation Awards. The system is covered by a three-year warranty with advance replacement for all three years, which is unusually long in this category and says something about how SOLiD expects it to hold up. Getting a system designed for your building Every building is different, so BARS is designed around yours rather than sold as a fixed package. Tell us your square footage, your construction, and where the dead zones are, and our design team will lay out the head-end, hubs, and remote units your floor plan needs, then send you pricing. The assessment is free, and if a simpler signal booster would solve your problem for less, we will say so.
