Frequently Asked Questions
Every facility has unique public safety communication requirements, and reliable in-building radio coverage starts with the right engineering approach. Here are answers to some of the most common questions we receive about ERCES, RF testing, public safety communications, and system design.
An Emergency Responder Communication Enhancement System (ERCES) improves in-building radio coverage for firefighters, police, and other emergency personnel. A properly designed ERCES helps maintain reliable public safety communications in areas where building materials, size, or layout may weaken radio signals.
The need for an ERCES is typically determined through public safety radio coverage testing and applicable local code requirements. Zagarri Engineering can evaluate your facility, identify coverage gaps, and determine whether a communication enhancement system is needed to support reliable emergency responder radio coverage.
Our team designs RF solutions for public safety communications (ERCES), Distributed Antenna Systems (DAS), cellular networks, WiFi, private wireless networks, and other specialized RF applications. Every design is customized to meet the specific needs of the project.
Every project begins with understanding your goals and evaluating existing conditions. We perform RF surveys, analyze coverage and interference, review building characteristics, and develop a design that balances performance, reliability, scalability, and budget.
Yes. Our services extend beyond engineering and design. We can assist with installation coordination, commissioning, performance testing, system optimization, and final validation to ensure your wireless system operates as designed before the project is complete.
