Weather Radar Interference Enforcement

The Enforcement Bureau recently took action against companies operating devices that caused interference to Terminal Doppler Weather Radars (TDWRs) maintained by the Federal Aviation Administration (FAA). TDWR systems serve the critical function of providing the FAA with quantitative measurements for gust fronts, windshear, microbursts, and other weather hazards. The FAA uses this information to improve flight safety at major airports.

Investigations conducted by the FCC, the FAA and the National Telecommunications and Information Administration (NTIA) in several areas of the United States and Puerto Rico revealed that much of the interference stems from wireless devices sharing the same band as TDWR systems, and operating outdoors under the FCC's Rules for Unlicensed National Information Infrastructure (U-NII) devices.  (These rules may be found at 47 C.F.R. Part 15 subpart E.)  The Enforcement Bureau and the FAA continue to investigate additional reports of interference to TDWR systems, and will continue to take appropriate enforcement action as necessary.

In addition, on July 27, 2010, the Enforcement Bureau and the Office of Engineering and Technology issued a memorandum providing guidance to manufacturers and operators of U-NII devices.
