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.

Verticals We Serve

Commercial Real Estate & High-Rise Buildings

Tall buildings and large office complexes are among the most common environments where cellular and public safety signals are degraded. Dense construction, reflective glass facades, and deep interior floor plates create significant coverage challenges. RFIP deploys DAS and ERRCS solutions that ensure tenants, visitors, and emergency responders have reliable wireless communications on every floor and in every common area — a critical factor in tenant satisfaction, building safety, and regulatory compliance.

Healthcare

Hospitals and medical campuses are complex, signal-hostile environments filled with dense construction, shielded rooms, and underground levels. Reliable cellular coverage supports clinical communications, telehealth, patient and family connectivity, and mobile device-dependent workflows. Equally critical, ERRCS ensures that fire and emergency teams can communicate seamlessly throughout the facility during a crisis — including in operating theatres, imaging suites, and below-grade areas where radio signals are most vulnerable.

Hospitality

Hotels, resorts, and conference centers depend on guest satisfaction, and wireless connectivity is now a baseline expectation. Dead zones in guest rooms, lobbies, ballrooms, and underground parking areas directly impact the guest experience and online reviews. DAS ensures consistent cellular coverage throughout the property, while ERRCS protects guests and staff by guaranteeing that emergency responders can communicate effectively in every area of the building.

Education

Schools, colleges, and universities encompass sprawling campuses with a mix of older buildings, modern construction, and large gathering spaces like lecture halls and athletic facilities. DAS solutions keep students, faculty, and staff connected, while ERRCS is essential for campus safety — ensuring that first responders can coordinate effectively during emergencies across buildings that may vary widely in construction type and signal penetration.

Transportation

Airports, transit stations, and terminals are high-traffic, high-stakes environments where both passenger connectivity and emergency communications are essential. These facilities often feature large open concourses, underground platforms, long tunnels, and complex multi-level layouts that challenge wireless coverage. DAS keeps travelers and staff connected, while ERRCS ensures that emergency teams can communicate without interruption throughout every area of the facility — including those hardest to reach.

Retail & Mixed-Use Developments

Large shopping centers, mixed-use complexes, and multi-tenant retail environments bring together diverse building footprints under one roof. Cellular coverage impacts everything from customer experience and mobile payment systems to in-store operations. ERRCS ensures that these densely occupied spaces meet code requirements and that first responders can operate safely and effectively in an emergency.

Government & Public Safety Facilities

Courthouses, municipal buildings, correctional facilities, and emergency operations centers demand the highest standards of communications reliability. DAS provides robust cellular coverage for daily operations, while ERRCS is mission-critical — these are the very buildings where first responder communication failures are least acceptable.

Sports & Entertainment Venues

Stadiums, arenas, concert halls, and convention centers present some of the most demanding environments for wireless and public safety communications. These venues combine massive occupancy, dense construction, large open-bowl structures, and extensive below-grade and back-of-house areas — all of which create significant challenges for both cellular coverage and emergency responder radio communications.

DAS is essential in these environments to ensure that cellular service remains reliable throughout the venue — in seating bowls, concourses, suites, club levels, press areas, locker rooms, loading docks, and underground service corridors. With tens of thousands of devices competing for signal during events, a properly designed DAS ensures that carrier services perform at the capacity the venue and its occupants demand. This supports everything from mobile ticketing and cashless transactions to operational communications and broadcast media connectivity.

ERRCS is equally critical. Large venues are high-occupancy, high-risk environments where emergency situations require immediate, coordinated response across vast and complex footprints. Fire crews navigating smoke-filled concourses, law enforcement coordinating across multiple levels, and EMS teams operating in below-grade staging areas all depend on uninterrupted radio communication. An ERRCS ensures that every area of the venue — including the most signal-challenged spaces — provides the radio coverage first responders need to protect lives. For many venues, compliance with ERRCS requirements is also a condition of maintaining their occupancy permits and event licenses. RFIP understands the unique demands of sports and entertainment environments and designs integrated DAS and ERRCS solutions that meet both operational and life-safety requirements — ensuring your venue delivers a connected experience while maintaining the highest standards of public safety.
