Dropped calls and weak indoor cell signals aren’t just frustrating—they can disrupt your business. That’s where a Cellular DAS (Distributed Antenna System) comes in. It captures the outdoor cellular signal, amplifies it, and delivers it evenly throughout your building, ensuring employees, customers, and guests receive reliable coverage wherever they are.

Cellular DAS working within a building.Certified Installation
Lumina Group, Inc. is a certified Level 2 installer of SureCall Cellular DAS systems. SureCall’s modular design makes it a perfect fit for small offices, but it also scales up seamlessly to cover large buildings, warehouses, or multi-story complexes.

How It Works
Outdoor Signal Capture: A donor antenna (Omni or Yagi, depending on conditions) pulls in the best available signal from nearby carriers.

Boost & Distribute: The signal is routed through a DAS booster and sent into the building.

Indoor Coverage: Low-profile ceiling domes spread signal in all directions, while panel antennas extend coverage down long hallways or into warehouse bays.

Why It Matters
From E-glass windows to concrete walls, modern buildings block cell signals. A Cellular DAS eliminates those dead zones—keeping calls clear, data flowing, and business running smoothly.

And yes, every SureCall booster we install is FCC-compliant for safe and reliable operation.

Cellular DAS FAQ

Yes. A DAS captures signal from all major carriers (Verizon, AT&T, T-Mobile, etc.) and distributes it inside your building, so everyone stays connected.

Yes, Wi-Fi and cellular DAS serve different purposes. Wi-Fi runs on your internet, while DAS improves your cell service for calls, texts, and mobile data.

Not at all. SureCall systems are modular, meaning they’re great for small offices and can scale up to cover warehouses, schools, or multi-story complexes.

That’s where specialized antennas come in. A Yagi antenna can reach distant towers and pull in a signal, which the DAS then boosts and distributes inside.
