United States: The FCC is proposing changes to emission limits for the 24.25-24.45 GHz and 24.75-25.25 GHz bands
Officially published at:2024-01-29On 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.

United States: The FCC has officially published regulations on the use of VLP in the 6 GHz band
Officially published at:2024-01-08Following the announcement by the U.S. Federal Communications Commission (FCC) on October 19, 2023 that the 6 GHz band will be opened for use by very-low power (VLP) devices, on January 8, 2024, the FCC published a rule on the Federal Register website regarding "Unlicensed Applications of the 6 GHz Band and Expanding the Flexible Use of the 3.7 to 24 GHz Band" to promote the update of the requirements in FCC Part 15. The new rules will allow VLP devices to be used in the U–NII–5 (5925–6425 MHz) and U–NII–7 (6525–6875 MHz) frequency bands. The new regulations will come into effect on March 8, 2024. In addition. The FCC is also considering opening up the entire 6GHz band to VLP equipment.

United States: The FCC has officially updated its regulations for the new standard
Officially published at:2023-09-29On September 29, 2023, the Federal Register officially released revisions to Title 47 to introduce a series of new standards:
- ANSI C63.4a–2017: Disturbance measurement method for low-voltage electrical and electronic equipment from 9kHz to 40GHz;
