Premium Scalability with SOLiD BARS
One BARS Headend supports up to four Hub Units, each designed to handle up to eight Remote Units. Modular architecture enables a wide range of configuration possibilities to fit any Middleprise facility – from a small office to a corporate campus.
Every SOLiD BARS in-building DAS solution is custom-designed to address varying coverage requirements, building layouts, signal environments, and budgets.
SOLiD BARS Solution Configurations
The Headend Unit receives off-air AT&T, T-Mobile, and Verizon signals via three outdoor directional antennas. Eight Remote Units amplify and distribute reliable multi-carrier coverage up to 100,000 sq ft* using a system of indoor antennas.
* Coverage values are estimated. Actual results vary based on outdoor signal conditions and building layout.

Frequently Asked Questions
Who is SOLiD BARS For?
A SOLiD BARS DAS solution is designed for facilities that need reliable cellular coverage throughout without the cost and complexity of an Active DAS. Applications include:
- Commercial Offices
- Hospitals and Healthcare Clinics
- Schools and Universities
- Hotels and Hospitality Venues
- Retail Stores
- Warehouse
- And More!
What Makes SOLiD BARS Different from an Active DAS?
Active DAS systems are typically best suited for very large and high-traffic venues. They require carrier participation, fiber backbones, high upfront investment, and often take months to commission and install. SOLiD BARS is different in several ways:
- Multi-carrier: Works with all three major U.S. carriers out of the box
- Off-air: No need for direct carrier connections or backhaul
- Ethernet-based: Uses standard Cat6A cabling
- Scalable: Easy to expand as your coverage needs grow
- Cost-effective: Designed to bring mobile coverage within budget for smaller buildings
How Does SOLiD BARS Differ from Other DAS Solutions in its Class?
- Superior Scalability – A single Headend supports up to 40 Remote Units using 4 Hub Units, reducing the need for additional Headend and donor equipment to cover larger buildings or campus environments.
- Amplifies Three Bands Per Carrier – Supports up to three frequency bands per carrier, ensuring higher-quality, multi-carrier coverage.
- CAT6a Ethernet Cabling – BARS uses high-grade CAT6A Ethernet cabling, making the system easier and faster to install.
- 5G NR-NSA Band Support – Supports multiple 5G NR-NSA bands, offering more reliable 5G connectivity throughout buildings.
What Coverage Can I Expect for SOLiD BARS?
Coverage varies depending on your building's size, layout, and existing outside signal conditions. With a single headend supporting up to 40 RUs, SOLiD BARS can be scaled to cover any facility up to 500,000 sq ft.
Is BARS Compatible with All Major Carriers?
Yes. SOLiD BARS supports all three major U.S. carriers at the same time – AT&T, T-Mobile, and Verizon. It can amplify up to three frequency bands per carrier, ensuring reliable connectivity for all building occupants regardless of the network they use.
How Much Does SOLiD BARS Cost?
Every building is different, requiring a unique, custom SOLiD BARS solution. Cost will vary depending on building size and coverage needs. Though, it is significantly more affordable than an Active DAS. Contact us at 1-800-420-3211 for a free consultation.
How Is SOLiD BARS Installed?
The installation process starts with a consultation to understand your needs, followed by a site survey to evaluate your existing signal conditions and building layout. Based on the findings, a custom SOLiD BARS solution is designed and deployed by a professional installer.
Can BARS Scale with My Business?
BARS is designed to grow with your facility's coverage needs. You can start with a partial solution that covers key areas and later expand to cover multiple floors or an adjacent building on your campus. It's easy to add additional remote units without replacing core components or disrupting the existing coverage.
