The Enforcement Bureau, through its field offices, supports the Commission’s public safety goals, including by investigating and resolving radio frequency interference caused to public safety communications and critical infrastructure. Interference complaints come from a variety of sources, but the Bureau’s highest priority is responding to complaints from those that protect the public and preserve security (e.g., Federal Aviation Administration (FAA) air traffic control and navigation, U.S. Coast Guard search-and-rescue operators, Emergency Medical Service technicians, police, and firefighters). The Field Offices also investigate and resolve instances of harmful interference to or from commercial entities (e.g., wireless providers, broadcasters) and other sources.

  • The Bureau works with federal, state, and local public safety agencies to resolve harmful interference to public safety communications and critical infrastructure communication systems. EB field agents determine the cause of interference using their radio frequency expertise and specialized instruments and equipment, including direction-finding equipment, to identify the source of radio frequency interference. Public safety entities experiencing harmful RF interference can file complaints electronically using the Radio Frequency Service Interference Complaint Portal.
  • The Bureau works with the Department of Homeland Security, U.S. Customs and Border Protection on cross-border interference matters and on matters involving importation of uncertified and unauthorized intentional, unintentional, and incidental radiators that can cause interference to licensed services.
  • The Bureau works with the FAA National Operations Center, the United States Coast Guard Navigation Center, and the U.S. Air Force on global positioning system (GPS) interference issues.
  • The Bureau’s field agents work closely with commercial wireless carriers and other licensees to investigate claims of harmful interference. Enterprises that are experiencing harmful RF interference can file complaints electronically using the Radio Frequency Service Interference Complaint Portal.
  • Consumers or members of the public experiencing RF interference may file complaints electronically with the FCC’s Consumer and Governmental Affairs Bureau using the Consumer Complaint Center. CGB will route RF complaints within the Field’s jurisdiction to the appropriate Field Office for investigation.
