On December 22, 2023, the U.S. Federal Communications Commission (FCC) published a proposed rule numbered FCC 23-114, which was published on the Federal Register website on January 29, 2024. The proposal proposes to modify the unwanted emission limits for the 24 GHz band to better protect passive sensors in the 23.6-24 GHz band for weather forecasting and scientific research, and to allow for more commercial flexibility in the use of the 24 GHz band (specifically the 24.25-24.45 GHz and 24.75-25.25 GHz bands). For end equipment operating at 24.25–24.45 GHz or 24.75–25.25 GHz, the proposed amendment to Part 30 would limit the total spurious emissions in any 200 MHz bandwidth in the 23.6-24 GHz band to no more than -29 dBW (1 dBm), which will be further tightened to -35 dBW (-5 dBm) after September 1, 2027.
