In-Building Cellular Coverage and DAS
When phones fail inside your building, SimpleCom measures every carrier, then designs and installs a distributed antenna system (DAS) that brings coverage to every floor.
When a DAS fits
Steel, concrete and energy-efficient glass block cellular signal. A DAS captures signal outside, then distributes it through the building so staff on any carrier can call, text and use their apps.
- Offices where staff on different carriers lose calls
- Warehouses and distribution centers with dead zones
- Large jobsites with no usable cell service
- Buildings full of single-carrier boosters that never solved the problem
- Facilities where coverage affects safety and operations
How SimpleCom delivers in-building cellular and DAS
Heat map survey
Walk tests show exactly where each carrier fails, floor by floor, before any design is drawn.
Multi-carrier design
One system covers staff on any carrier, replacing stacks of single-carrier extenders.
Roof-to-ceiling install
Rooftop donor antennas, building penetration, head-end and ceiling antennas, planned and installed by SimpleCom.
Common questions
What is a DAS?
A distributed antenna system brings cellular signal into a building through a donor antenna on the roof, a head-end and antennas mounted throughout the space.
Why not just add a booster?
A plug-in booster usually helps one carrier in one spot. A DAS is designed from survey data to cover every carrier across the whole building.
Do you survey before designing?
Yes. Every DAS project starts with heat map surveys, so the design is based on measured signal rather than guesses.
Can you cover a site with no cell service at all?
Yes. On remote jobsites we pair satellite backhaul with a network extender and a broadcast antenna to create coverage where none exists.
