Modification of Emission Limits for 24 GHz Bands

On Monday January 29th, 2024, the Federal Communications Commission proposes the implementation of certain decisions regarding the 24.25-27.5 GHz band made in the World Radiocommunications Conference held by the International Telecommunication Union (ITU) in 2019 (WRC-19). Specifically, the commission proposed to align part 30 of the Commissionsโ€™s rules for mobile operations with the Resolution 750 limits on unwanted emissions into the passive 23.6-24.0 GHz band that were adopted at WRC-19. The proposed rule changes would help facilitate the protection of passive sensors used for weather forecasting and scientific research in the 23.6 GHz-24 GHz band, while continuing to promote flexible commercial use of the 24.25-24.45 GHz and 24.75-25.25 GHz Band (collectively, 24 GHz band). The Commission also seeks comments on alternatives to the proposals it makes, and on other related issues.
