FCC NARROWBANDING MANDATE – A Public Safety Guide for Compliance
The International Association of Fire Chiefs (IAFC) and the International Municipal Signal Association (IMSA) developed this guide to help state and local public safety agencies understand and comply with the FCC’s mandatory narrowbanding requirements. The mandate is designed to improve spectrum efficiency, reduce interference, and support more reliable mission-critical communications. This brochure outlines key compliance considerations, timelines, and impacts to existing radio systems—serving as a practical reference for agencies evaluating their current infrastructure and next steps.
