Eliminate Dead Zones Across Your Building
Large and modern buildings often block cellular signal, causing dropped calls and slow data. A Distributed Antenna System (DAS) distributes strong, reliable coverage throughout your facility — for all carriers — using a network of antennas fed by a signal source. We provide RF site surveys and design, carrier DAS, and public-safety DAS (ERRCS) to meet fire-code requirements for first-responder radio coverage. Boston High Tech engineers and installs in-building DAS across Massachusetts, New York & New Jersey — and nationwide for multi-site projects.

DAS Systems & Code Compliance
Public-safety ERRC and commercial cellular DAS — surveyed, designed, permitted and certified.
Public-Safety ERRC / BDA
Code-required first-responder coverage (NFPA 72/1225, IFC 510) — UHF/VHF and 700/800 MHz BDA systems with battery backup, annunciators and AHJ acceptance testing.
Cellular DAS
Carrier-agnostic boosters and hybrid DAS (WilsonPro, SureCall) that fix dead zones for Verizon, AT&T, T-Mobile and FirstNet across garages, high-rises and warehouses.
Survey & Grid Testing
Baseline RF surveys, iBwave-grade design, and post-install grid testing documentation — the paperwork inspectors and carriers actually accept.
When Code Requires DAS
Most jurisdictions now require ERRC verification for new construction and major renovations — dense concrete, metal deck, LEED glass and below-grade areas routinely fail. We test first (many buildings pass), and when amplification is required we design, permit, install and schedule the annual retests the code demands. For cellular-only problems, see our Wilson and SureCall pages. Call 1-866-625-1977.
In-Building DAS — Frequently Asked Questions
What is a DAS?
A Distributed Antenna System distributes cellular (and public-safety radio) signal throughout a building using a network of antennas for reliable coverage.
Do you provide public-safety DAS?
Yes — we design and install ERRCS public-safety DAS to meet fire-code requirements for first-responder radio coverage.
Does DAS work for all carriers?
Yes — a properly designed DAS provides coverage for all major carriers throughout your building.
Do you serve clients outside MA, NY & NJ?
Yes — while we’re based in the Northeast, our software and technology teams support multi-site and nationwide projects. Call 1-866-625-1977.

Certified In-Building DAS & Cellular Design, Installation and Support
Boston High Tech provides end-to-end In-Building DAS & Cellular services for commercial properties and organizations across Massachusetts, New York and New Jersey. We start with a site review and a clear discussion of users, operating requirements, existing systems, future growth and project constraints. Our team then develops a practical scope covering equipment, pathways, network needs, integration, testing and handoff.
What a complete project can include
- On-site assessment and review of existing infrastructure
- System design, equipment selection and written project scope
- Cabling, mounting, termination, configuration and integration
- Device-by-device testing, labeling and project documentation
- Administrator orientation, user training and support planning
Every proposal is tailored to the property. Reuse of existing wiring, readers, cameras, locks, network equipment or software is evaluated during discovery rather than assumed. Where another trade is required, we coordinate responsibilities with the client, general contractor, electrician, locksmith or IT team.
Our certified technology professionals support organizations across Massachusetts, New York and New Jersey from regional offices in Brighton, New York City and Skillman, with company headquarters in Charlotte. We keep private credential records, certificate numbers and individual certificate-holder information off the public website while maintaining the qualifications required for the work we perform.
