What It Is
A distributed antenna system (DAS) is a network of antennas distributed throughout a building, connected to a shared signal source, that brings cellular coverage indoors where building materials, geometry, or distance from a macro tower block it naturally.
When You Need It
DAS is typically required when a building's size, construction (low-E glass, concrete, structural steel), or occupancy triggers a local fire code requirement for emergency responder radio coverage — and it's the right answer whenever indoor cellular coverage is inconsistent enough to affect patient care, guest experience, or life-safety communication.
Our Methodology
1. Independent RF audit. We measure actual in-building signal strength across all relevant carriers and public safety frequencies before recommending anything.
2. Code review. We identify which local fire and building codes apply to the specific facility and jurisdiction.
3. Neutral-host system design. We design for the carriers your occupants actually use, structured for multi-carrier participation rather than a single-carrier build.
4. Phased installation planning. Especially in active facilities like hospitals, we sequence work to avoid disrupting operations.
5. Carrier and AHJ acceptance testing. We manage the testing and documentation required for carrier sign-off and fire marshal approval.
Typical Deliverables
- Independent RF coverage audit across all major carriers
- Applicable code determination (NFPA 72 / local fire code)
- Neutral-host DAS design and vendor-neutral equipment selection
- Phased installation and cutover plan
- Carrier acceptance and AHJ inspection documentation
Regional health system closes coverage gaps without disrupting patient care
A three-hospital system had clinical mobile devices losing signal in specific wings. See how a phased DAS retrofit solved it without a single disruption to active units.
