The U.S. Federal Communications Commission (FCC) has modified emissions limits applicable to frequency bands used for certain mobile operations to align its requirements with those of other national telecommunications authorities.
According to a Report and Order, the Commission has modified its rules for the 24.25-24.45 GHz and 24.75-25.25 GHz bands to align with a Resolution passed in 2019 by the World Radiocommunication Conference (WRC-19). Specifically, the FCC has aligned the requirements detailed in Part 30 of its rules for mobile operations in these frequencies with the limits set forth in WRC-19 Resolution 750.
Currently, the 23.6-24.0 GHz band is allocated for use by certain passive scientific and research services, including the Earth Exploration Satellite Service (EESS), essential to meteorological applications such as weather forecasting. According to the FCC, its rule changes are intended to protect the 23.6-24.0 GHz band from unwanted emissions that could adversely impact its use.
