Full-Building Cellular Coverage. No Dead Zones.
If people walk outside to make calls or lose signal in your stairwells and parking levels, you don't have a carrier problem - you have a building problem. DAS solves it at the infrastructure level.
SRS Networks designs, installs, and commissions distributed antenna systems for large commercial buildings, hospitals, campuses, and new construction - covering all major carriers and meeting public safety radio compliance requirements.
Why Large Buildings Have Cellular Dead Zones
Modern building materials actively block cellular signal. The larger and more complex the structure, the worse the coverage - and the harder it is to fix without engineered infrastructure.
Dead Zones Throughout the Building
Concrete floors, steel framing, low-e glass, and dense interior walls all kill cellular signal. If occupants are stepping outside to make calls, you have a DAS problem - not a carrier problem.
Public Safety Radio Gaps (Fire Code Violations)
Most jurisdictions require reliable two-way radio coverage for first responders throughout a building. If your new construction doesn't pass BDA/ERRCS testing, the certificate of occupancy is at risk.
No Coverage for Multi-Carrier Environments
Your occupants aren't all on the same carrier. A solution that only boosts one carrier leaves everyone else on the same dropped calls and slow data they started with.
IoT and Building Systems Relying on Cellular
HVAC controls, access systems, elevator monitors, and emergency panels increasingly depend on cellular connectivity. Signal dead zones disrupt more than phone calls.
Carrier Self-Install Won't Work Here
Consumer signal boosters and off-the-shelf solutions are prohibited in commercial buildings and won't touch a 200,000 sq ft facility. Professional infrastructure is the only viable path.
Engineered DAS Infrastructure Built for Your Building.
A distributed antenna system replicates carrier signal inside your building by distributing it through a network of antennas connected to a central headend. SRS handles the full lifecycle - RF survey, system design, cabling, installation, carrier coordination, and code compliance testing - under one engagement.
End-to-End DAS Design and Installation
From the initial RF survey to carrier sign-off and AHJ inspection, SRS Networks manages every phase of your DAS project - so you're not coordinating between four different specialists.
RF Survey & Design
We start with a professional RF survey of your building - floor by floor, room by room - mapping existing signal levels and identifying exactly where coverage falls short.
System Design & Engineering
Our engineers design an antenna distribution system tailored to your building's structure and coverage requirements - passive, active, or small cell - with carrier and AHJ coordination built in.
Installation & Commissioning
Certified installers run the coaxial or fiber backbone, mount antennas, rack headend equipment, and commission the system - leaving you with a fully tested, code-compliant installation.
Testing, Carrier Coordination & Handoff
Once installed, we coordinate with carriers for signal injection, conduct full RF validation testing, and deliver a complete as-built documentation package with proof-of-performance records.
Dead Zones vs. Engineered DAS Coverage
What changes when you replace patchwork consumer boosters and carrier-dependent coverage with a professionally engineered distributed antenna system.
Facilities That Require DAS
SRS Networks has designed and installed DAS infrastructure in facilities where reliable in-building cellular coverage is non-negotiable - operationally and legally.
Hospitals & Medical Facilities
Clinical environments demand reliable cellular for patient communication, IoT medical devices, staff coordination, and emergency radio coverage - every floor, every wing, no exceptions.
Convention Centers & Stadiums
High-density venues with thousands of simultaneous users require active DAS infrastructure capable of handling massive concurrent cellular load without congestion.
High-Rise Commercial Buildings
Multi-floor office towers lose carrier signal above the second floor. DAS distributes signal throughout every occupied floor, including parking structures and stairwells.
New Construction Compliance
Building developers and general contractors bring SRS in during construction to design and install DAS infrastructure that satisfies fire marshal BDA/ERRCS requirements before CO inspection.
DAS Is Not a Commodity. Experience Matters.
In-building cellular infrastructure requires RF engineering expertise, deep carrier relationships, and working knowledge of local AHJ fire code requirements. Getting it wrong means failed inspections, dead zones that persist, and carrier rejection. We've done this enough times that none of those surprises happen on our jobs.
