Cellular DAS/ERRCS
In-building coverage and emergency communications that just work.

Modern buildings and large-scale venues are designed to impress — but the very materials and construction methods that make them architecturally striking often block or degrade the wireless signals that people and emergency services depend on. Steel, concrete, low-emissivity glass, and dense interior layouts can create coverage dead zones that leave occupants disconnected and first responders unable to communicate when it matters most.
RFIP designs and deploys Distributed Antenna System (DAS) and Emergency Responder Radio Communication System (ERRCS) solutions that eliminate these gaps, ensuring reliable wireless coverage and life-safety communications throughout every corner of your facility.
Distributed Antenna Systems (DAS)
A Distributed Antenna System is a network of strategically placed antennas connected to a common signal source, designed to distribute wireless coverage evenly throughout a building or venue. Rather than relying on a single external cell tower to penetrate a structure, a DAS brings the signal inside — amplifying and distributing it across floors, wings, underground areas, and hard-to-reach spaces.
RFIP works with all major carriers to design and deploy DAS solutions that enhance cellular voice and data coverage for building occupants, tenants, staff, and visitors. Whether the solution calls for a passive DAS using coaxial cable and passive components, an active DAS with fiber-fed remote nodes, or a hybrid approach, RFIP evaluates your environment and designs a system that delivers consistent, reliable coverage at the capacity your building demands.
The result is a facility where dropped calls, dead zones, and poor data speeds are eliminated — and where every person inside the building has the connectivity they expect and need.
Emergency Responder Radio Communication Systems (ERRCS)
When an emergency occurs, the ability of fire, police, and EMS personnel to communicate inside a building can be the difference between life and death. ERRCS — also known as public safety DAS or in-building public safety communication systems — are specifically designed to ensure that first responder radio signals reach every area of a structure, including stairwells, basements, parking garages, elevator shafts, and interior corridors where signals are most likely to fail.
ERRCS is not optional in most jurisdictions. Building codes and fire codes — including the International Fire Code (IFC) and NFPA standards — increasingly require that new and renovated buildings demonstrate adequate in-building radio coverage for emergency responders. If a building cannot meet the required signal thresholds, an ERRCS must be installed before a certificate of occupancy is granted.
RFIP manages every phase of the ERRCS process, from initial signal testing and code analysis through system design, installation, commissioning, and final inspection with the Authority Having Jurisdiction (AHJ). We ensure your system is fully compliant with local, state, and national requirements — and that it performs reliably when lives depend on it.
Why RFIP
DAS and ERRCS projects are complex undertakings that require specialized RF engineering expertise, coordination with carriers and public safety agencies, and a thorough understanding of building codes and regulatory requirements. RFIP brings all of this to every engagement. From the first signal survey through final AHJ inspection, we manage the entire process — designing systems that perform, ensuring compliance with all applicable codes, and delivering solutions that protect both connectivity and safety for years to come.
Don't let your building's construction stand between your occupants and the coverage they need — or between first responders and the communications that save lives. Contact RFIP to learn how our DAS and ERRCS solutions can keep your facility connected and compliant.
