THE MIAMI AIR ROUTE TRAFFIC CONTROL CENTER (ZMA ARTCC) HAS EXPER- IENCED RADIO FREQUENCY INTERFERENCE (RFI) ON FREQUENCIES 134.2, 134.6 MHZ RESULTING FROM THE UNAUTHORIZED USE OF HIGH POWER CORDLESS TELEPHONES IN THE BAHAMAS AND ON FREQUENCY 133.85 MHZ FROM THE USE OF HIGH POWER CORDLESS TELEPHONES IN MIAMI. THE CLEVELAND AIR TRAFFIC CONTROL CENTER ARTCC (ZOB) OPERATIONS WERE ALSO IMPACTED DUE TO RFI ON FREQUENCY 134.65 MHZ, FROM THE UNAUTHORIZED USE OF HIGH POWER CORDLESS TELEPHONE LOCATED IN HARRISON, MICHIGAN. HIGH POWER CORDLESS TELEPHONES ARE BEING USED ILLEGALLY IN THE U.S. AND THE BAHAMAS. THESE PHONES CAN INTERFERE WITH THE FREQUENCIES USED FOR AIR TRAFFIC CONTROL WORLDWIDE AND CAN POSE PROBLEMS TO ATC NAVIGATION AND COMMUNICATIONS. PART 1 OF 2 WIE UNTIL UFN 

A0015/01 - THE FAA IS WORKING WITH OTHER GOVERNMENT AGENCIES WITHIN THE UNITED STATES AND OTHER COUNTRIES TO CURTAIL ILLEGAL USE OF THESE PHONES AND IS APPROACHING VENDORS TO CEASE DISTRIBUTION AND PRODUCTION OF UNITS THAT OPERATE IN OR CAUSE INTERFERENCE TO CRITICAL AERONAUTICAL RADIO SPECTRUM. USERS OPERATING ON THESE FREQUENCIES SHOULD BE AWARE THAT NAVIGATION AND COMMUNICATION COULD BE SEVERELY IMPACTED DUE TO RFI OF THESE HIGH POWER CORDLESS TELEPHONES. USERS OF AERONAUTICAL RADIO NAVIGATION AND COMMUNICATION SERVICES WHO EXPERIENCE THIS TYPE OF INTERFERENCE SHOULD REPORT ANY EVENT IMMEDIATELY TO THE AIR TRAFFIC FACILITY PROVIDING AIR TRAFFIC SER- VICES. IF THIS IMMEDIATE REPORT IS UNACHIEVABLE, THE USERS SHOULD MAKE A REPORT TO THE NEAREST AIR TRAFFIC FACILITY AT THE EARLIEST TIME POSSIBLE AFTER THE RFI EVENT. PART 2 OF 2 WIE UNTIL UFN
