Strengthening your signal with our design and compliance advisory services

Energy-efficient construction is killing your signal. We make sure it doesn't.

Your signal is trapped inside your own walls

Low-E glass and LEED construction are great for energy bills and terrible for cellular and public safety radio signals. You are left with dead zones, failed AHJ inspections, and occupants who cannot make a call when it matters most.

Signal-blocking materials

Modern energy-efficient glass and concrete turn your building into a Faraday cage, blocking the radio frequencies your people and first responders depend on.

Fragmented carrier coverage

Each carrier has its own requirements and no one is coordinating them, leaving you with a patchwork of coverage that fails when you need it most.

Last-minute compliance testing

Waiting until construction is done to test public safety signals is a gamble that costs you failed occupancy permits, $50,000 retrofits, and serious liability exposure.

We know what it is like when the fire marshal will not sign off

Don't delay your opening date. Make sure all the boxes are checked for sign-off. For ten years we have been the single, vendor-independent authority for in-building DAS, ERRCS, and small cell design across healthcare, education, government, and civic facilities—tied to no carrier and no product line, so every design decision serves your building, not a catalog.

Services

A clear signal from design to sign-off

We map your dead zones before you break ground, design systems that carriers and AHJs approve the first time, and stand beside you until the fire marshal signs the permit.

Predictive modeling and site surveys

We map your dead zones and model signal propagation before construction starts so you never have to guess where coverage will fail.

System design and carrier coordination

We deliver ERRCS, DAS, and small cell designs that meet every carrier specification and AHJ requirement so you get approval the first time.

Commissioning and compliance testing

We conduct grid testing, verify signal strength, and support fire marshal sign-off so your occupancy permit is never at risk.
