Distributed Antenna Systems (DAS) for Consistent Indoor Coverage
If your building drops cellular calls, struggles with data speeds, or blocks radio frequency signals, you’re not alone. Structures built with metal, concrete, or energy-efficient glass often prevent wireless signals from reaching interior spaces. That’s why Distributed Antenna Systems (DAS) are so important for Arizona properties, especially in hospitals, stadiums, apartment complexes, and corporate campuses.
At RFE Communications, we design custom DAS networks using advanced IBwave software. These systems include indoor antennas, amplifiers, and coaxial cable that distribute strong signal throughout the building. Whether your site needs LTE, 5G, or multi-carrier support, we can tailor a network that improves mobile phone performance, reduces dropped calls, and increases safety for all users.
We begin with grid testing and signal generator analysis to pinpoint dead zones. From there, we engineer and install a comprehensive system that strikes a balance between cost, performance, and scalability. Our DAS solutions make your building more functional, your tenants more satisfied, and your infrastructure future-ready.
Emergency Responder Radio Coverage Systems (ERRCS) That Meet Arizona Code
First responders must be able to communicate clearly in every part of a building, especially during a fire, power outage, or evacuation. Arizona building codes, enforced by local fire departments and the International Code Council (ICC), require Emergency Responder Radio Coverage Systems (ERRCS) in most new and renovated commercial properties. These systems ensure that firefighters, EMTs, and police stay in constant contact during emergencies.
RFE Communications is highly experienced in ERRCS installation, repair, design, and testing. We work with local Authorities Having Jurisdiction (AHJs), engineers, and fire marshals to meet National Fire Protection Association (NFPA) standards. Our ERRCS systems use bi-directional amplifiers (BDAs), directional antennas, and ultra-high frequency (UHF) technology to create full-building coverage, including in stairwells, elevators, pump rooms, and garages.
Our process includes thorough ERRCS testing, fire alarm system integration, and documentation for certificate of occupancy approval. We also install backup power systems, battery chargers, and uninterruptible power supplies to ensure the ERRCS functions even during blackouts. From plan review to final inspection, we help you meet fire safety codes and protect lives.
Bi-Directional Amplifier (BDA) Systems That Keep Signals Strong
BDA systems are essential for improving weak signals in large or complex buildings. Whether you need to boost a public safety network or a cellular repeater system, BDAs take in weak signals from outside and amplify them throughout the interior. In Arizona, BDA systems are often used in facilities where thick walls, multi-level construction, or remote locations block a consistent signal.
RFE Communications handles the full design and installation of BDA systems. We test signal strength in each zone, design layouts that include coaxial cable runs, power supply integration, and antenna placement, and ensure compatibility with your existing telecommunications or emergency service systems. Our BDA installations support both cellular and public safety networks, with seamless performance and regulatory compliance.
Regular BDA testing is critical to proper BDA operation. Using spectrum analyzers and dBm meters, we verify that signal levels meet jurisdictional requirements and document everything needed for fire marshal review. From emergency service radio to smartphone data speeds, our BDA systems keep communication flowing.
ERCES & Starlink: Specialized Solutions for Unique Properties
Some buildings require an added level of signal assurance. Emergency Responder Communication Enhancement Systems (ERCES) are designed to support public safety communication in buildings where even ERRCS systems fall short. These systems enhance signals in traditionally blocked areas, such as basements, stairwells, or mechanical rooms. Our engineers build ERCES installations that support the First Responder Network Authority (FirstNet) and ensure compliance with local and national regulations.
Meanwhile, remote job sites and facilities in rural Arizona often lack high-speed internet access. Our team installs Starlink satellite systems to bring fast, reliable internet to areas where traditional cable or fiber won’t reach. From ranches and rural manufacturing plants to mobile command centers, Starlink helps you stay connected when you’re off the grid. We handle the installation, alignment, and system optimization so you can focus on operations instead of infrastructure.
Every system we install — whether ERCES, DAS, or Starlink — includes full project documentation, inspection readiness, and ongoing maintenance support. We build communication systems that are ready for the unexpected.
