Distributed Antenna System Installation
Distributed antenna system installation connects the equipment specified for a building’s cellular coverage plan. Start with an RF review, intended carriers and an agreed acceptance scope.
SRS Networks designs, installs, and commissions distributed antenna systems for commercial buildings, hospitals, campuses and new construction under a defined project scope. Cellular coverage and public-safety radio work require separate acceptance plans.
SRS Networks is a nationwide infrastructure deployment partner headquartered in South San Francisco, California, serving commercial sites across the 48 contiguous states, Alaska, and Hawaii since 1996. DAS installation follows an agreed RF design, carrier coordination plan and coverage acceptance scope.

What to request from DAS installation companies
Ask who surveys the building, who owns the design, who coordinates carriers and who signs the final coverage report. Compare experience and credentials for the actual system proposed rather than accepting a broad low-voltage claim.
Keep public-safety work separately defined
A cellular coverage project should not silently become an emergency-radio compliance project. Identify each system's purpose and qualified delivery team in the scope, and obtain the applicable approvals before committing to a completion date.
Bring these details to the estimate
- Floor plans, coverage concerns and intended carriers
- RF survey and approved equipment/design responsibility
- Antenna, backbone, power and access requirements
- Carrier coordination, commissioning and acceptance owners
What changes the price
Building geometry, signal distribution design, carrier coordination, cable routes, equipment locations and the required commissioning work affect price. Separate survey, design, installation and acceptance so bidders are pricing the same responsibility.
Cellular DAS and public-safety radio coverage are separate scopes. Carrier permissions, equipment eligibility and any jurisdictional requirements need confirmation by the responsible specialists before installation; no blanket approval or coverage guarantee is implied.
Make acceptance part of the work order
- Design ownership
- Identify the approved design, equipment schedule and responsible RF specialist.
- Installation evidence
- Record antenna locations, cable identifiers and the specified test results.
- Coverage acceptance
- Have the responsible specialist verify the agreed test areas and document exceptions.

Questions to settle before deployment
What should DAS installation companies include in a proposal?
Identify the survey, design, equipment, installation, carrier coordination and acceptance responsibilities. Include coverage areas, exclusions, test deliverables and the process for correcting a failed acceptance result.
Are cellular DAS and public-safety radio systems the same scope?
They serve different purposes and need separate requirements and acceptance plans. Do not treat a cellular installation proposal as proof that public-safety coverage obligations have been met.
Who should own the DAS design?
Name the responsible RF designer or system provider in the work order. The installation team should work from the approved design and document proposed changes before making them.
What determines the cost of DAS installation?
Building layout, cable routes, access, equipment locations, carrier coordination and commissioning requirements affect effort. Separate survey and design costs from installation and final acceptance.
Can a WiFi survey replace the cellular coverage review?
The project should use a survey appropriate to the system and coverage objective being evaluated. Confirm the required measurements with the responsible RF specialist rather than assuming a WiFi assessment settles cellular coverage.
What information is needed before dispatching installers?
Provide the approved floor plans and design, equipment list, access permissions, power/pathway readiness and contacts for the carrier and commissioning team.
Is a consumer signal booster always prohibited in a commercial building?
No blanket prohibition should be assumed. Equipment type, intended use and applicable carrier and regulatory requirements need review before choosing a system. Confirm suitability with the responsible specialist.
What should be delivered at DAS handover?
Request installed equipment and cable records, marked antenna locations, the specified test results, the coverage acceptance report and a documented list of remaining exceptions and owners.
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
Building materials and layout can affect indoor cellular coverage. Survey the areas of concern and check carrier conditions before selecting an in-building system.
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
Equipment suitability depends on the coverage objective, system type and applicable carrier requirements. Compare an approved design with the measured building conditions before choosing equipment.
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
The installation team runs the specified backbone, mounts antennas and racks the equipment. The responsible specialist commissions the system against the agreed acceptance plan.
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.
