Question 1

Does our building actually need a public-safety ERCES?

Accepted Answer

That's the AHJ's call — usually the fire marshal — and it most often lands on high-rises, large commercial buildings, healthcare facilities, and anything with below-grade space where radio signal dies. The only honest way to answer it for your building is an RF survey: grid measurements checked against the coverage thresholds in IFC 510 and NFPA 1225. Sometimes the survey shows you pass and no system is needed — that's a good outcome too, and you get it documented for plan review.

Question 2

What's the difference between cellular DAS and public-safety ERCES?

Accepted Answer

Cellular DAS carries carrier networks — the bars your tenants see — and is driven by tenant experience. ERCES carries first-responder radio and is driven by fire code: it's often a condition of your certificate of occupancy, with stricter rules on coverage, battery backup, pathway survivability, and annual retesting. Some buildings need both. They're separate systems designed to different rules, and we scope the survey to cover whichever apply.

Question 3

What does the design package include?

Accepted Answer

iBwave predictive and measured design, antenna placement, link budgets, equipment schedules, and construction-ready drawings — plus the survey data behind them. It's the format AHJs and carriers recognize, so your integrator can build from it and your plan reviewer can approve it without a round of clarification requests.

Question 4

Do you install the system too?

Accepted Answer

No — we're the survey and design side, on purpose. Your integrator or GC builds from our package, and we stay available for design questions through plan review and acceptance testing. Keeping design independent of installation means the system gets sized to what the building needs, not to the equipment someone wants to sell.

Question 5

What drives the cost of an in-building system?

Accepted Answer

Square footage, construction materials, how much signal the building kills, and which code path applies — ERCES carries requirements like battery backup and pathway survivability that cellular doesn't. That's why the survey comes before anyone specs equipment: it establishes whether you need a system at all and, if so, how much system the building actually needs. You commit to hardware from real numbers, not estimates — and the survey and design package itself is a fixed quote, a small line item next to the hardware spend it right-sizes.

Question 6

We failed an annual test or got an AHJ notice — how fast can you move?

Accepted Answer

Fast — violation response is a specific service, not a squeeze into our normal schedule. We prioritize the survey, design to your AHJ's submittal requirements, and turn the package around on the compliance clock you've been given. Bring the notice and your floor plans to the first call.
