Modern building materials, underground levels, and low-E glass block macro signals indoors — creating dead zones, dropped calls, and degraded data that can stall Certificate of Occupancy when public-safety ERCES fails inspection. We deliver RF site surveys and iBwave-certified DAS design for public-safety (ERCES) and cellular in-building wireless — donor antenna selection, BDA / head-end specification, and fiber or coax distribution — across all five NYC boroughs. One accountable partner from field measurements through AHJ-ready documentation, at a fraction of what turnkey DAS agencies charge for design alone. Proven on U.S. DoD facilities where first-responder and in-building coverage must pass inspection.
How a DAS Works
A distributed antenna system distributes RF through a network of antennas tied to a signal source — engineered for full coverage with minimal overlap and lower power draw than a single large antenna. Carrier-grade signal enters the head-end (captured off-air via donor antenna and BDA, or fed from a dedicated BTS / small cell), then travels over fiber and coax to remote units on every floor. Dead zones, dense occupancy, or ERCES for first responders — we model the full chain in iBwave so coverage and capacity hold before construction starts.
What We Design
Whether you need ERCES for code compliance, cellular DAS for tenant and guest connectivity, or both — every project starts with measured RF data and ends with a design package owners, integrators, and the Authority Having Jurisdiction can act on. No layered hand-offs through a national turnkey agency.
On-site spectrum analysis, 20-grid signal-strength mapping, and infrastructure walk-through — cable pathways, power, and equipment space — before any antenna is specified. Enterprise buildings, mid-rise retrofits, venues, and campus additions.
Propagation modeling, remote antenna unit layout, and signal-source selection (off-air BDA, dedicated BTS, or small cell) for active, passive, or hybrid DAS architectures — including multi-carrier and multi-band (LTE / 5G) where cellular coverage is in scope.
Emergency Responder Communication Enhancement System design for reliable first-responder radio coverage inside the building — aligned with NFPA 1225 and IFC 510, the public-safety standards NYC AHJs enforce at inspection.
Code & Compliance
Emergency Responder Communication Enhancement Systems (ERCES) ensure police, fire, and EMS can communicate inside your building — enforced under NFPA 1225 and IFC 510. A failing public-safety radio test can delay your Certificate of Occupancy and trigger a corrective window from the AHJ. We help building owners and property managers move from notice to a documented design path — quickly, with field data and iBwave models behind every decision.
NFPA 1225 / IFC 510
Public-safety radio coverage standards referenced by NYC and most U.S. AHJs at plan review and inspection.
20-grid coverage testing
Minimum -95 dBm signal in 95% of the structure — validated grid by grid during survey and design.
Donor and off-air signal sources
Carrier coordination, BDA / head-end specification, and signal-source selection — multi-carrier capable where cellular DAS is in scope.
Right-sized project focus
Enterprise buildings, single-floor retrofits, mid-rise properties, and venues — scopes large turnkey firms often queue behind.
The Process
Three phases, one partner — from AHJ notice to a buildable design package, without the subcontractor maze typical of end-to-end turnkey operators.
We measure existing coverage against a 20-grid pattern, document dead zones and donor signal options, and map cable pathways, power, and head-end space — the field data every credible design starts from.
Antenna count and placement, BDA / head-end specification, fiber and coax distribution, and signal-source selection — modeled in iBwave before a single remote unit is mounted.
Construction-ready drawings, bill of materials, and a coordinated package your integrator, general contractor, or Authority Having Jurisdiction can review without chasing multiple vendors.
Large DAS firms sell turnkey install-and-operate models with enterprise overhead. We focus on what most NYC owners need first: a credible survey, an iBwave-certified design, and documentation your AHJ and integrator can use — scalable from single-floor retrofits to multi-carrier campus additions. Because we also build software and secure infrastructure, our engineering rates stay competitive without cutting corners on RF quality.
