Physical Infrastructure — Principal Service
Cellular coverage that reaches every corner of the building.
Apex Premier Solutions designs and installs both types of in-building coverage systems: cellular DAS, which boosts carrier signal where steel, concrete, or size block reliable service — and ERRCS (Emergency Responder Radio Communication Systems), the code-required radio coverage that lets fire and police communicate inside your building. Every system starts with an on-site coverage assessment and is engineered to current fire and building code.
What's Included
Scope of service
- On-site RF coverage assessment — confirm the need before buying the system
- Cellular booster and antenna system design, carrier-agnostic
- ERRCS design and installation — Emergency Responder Radio Communication Systems, where fire code requires them
- Code-compliant installation coordinated with fire marshal and AHJ requirements
- Coordination with carrier and AHJ requirements during design
- Ongoing service and monitoring options after handoff
Before You Call
Common questions
Does my building need a DAS system?
If staff or visitors regularly lose cellular signal inside the building — especially in stairwells, basements, or interior rooms — a DAS is likely warranted. Apex Premier Solutions performs a coverage assessment before recommending one, so you're not paying for a system you don't need.
What is ERRCS, and is it required in my building?
ERRCS (Emergency Responder Radio Communication System) provides the in-building radio coverage that lets firefighters and police communicate inside a structure. Fire code requires it in most new commercial buildings above a certain size — and in many existing buildings at renovation. Apex Premier Solutions confirms your Authority Having Jurisdiction (AHJ) requirements during the design phase and installs to code.
What is the difference between cellular DAS and ERRCS?
Cellular DAS boosts commercial carrier signal (Verizon, AT&T, T-Mobile) for occupants; ERRCS boosts public-safety radio frequencies for emergency responders and is mandated by fire code. Apex Premier Solutions designs and installs both, often in the same building.
