Weather, foliage, building materials, and construction progress all impact radio frequency performance, making accurate ERCES site surveys essential. Because conditions change as a building is completed and across seasons, early signal readings can be misleading. Conducting site surveys at multiple construction stages helps ensure ERCES systems correctly address only the areas with inadequate first responder radio coverage.

Year-end slowdown? Use this time to complete required ERCES annual inspections, stay compliant, and keep crews working. 2026 Potter ERCES training is now open.

Installing an ERCES requires more than certifications—it demands the right tools. From site survey scanners to spectrum analyzers and cable prep gear, here’s what you need for a successful setup.

ERCES code requirements vary widely by jurisdiction, causing confusion for integrators. Differences in code adoption, survivability standards, approved components, and system classifications can impact cost and deployment. Coordinating directly with the local AHJ is essential, and NFPA 1225 provides the most current national guidelines.

Building occupancy requires adequate radio signal for first responders. Coordination between the AHJ (indoor signal) and FCC Licensee (external network) is key. Improper ERCES can harm the wider network. Find the Licensee via NFPA 1225, call sign/FCC database, or municipal sites. Licensee coordination is vital for ERCES commissioning and requires a Retransmission Agreement to prevent network interference, ensuring reliable first responder communication.
