Sharing in the 12 GHz Band

As the “traditional” mid-band frequencies of sub-6 GHz get allocated for various services, there has been increasing focus on the 7–24 GHz band for the next generation of terrestrial mobile wireless systems to find a home in. On May 18, 2023, the U.S. Federal Communication Commission (FCC) voted unanimously to adopt new rules for the 12.2-13.25 GHz band that would permit such services in part of the band, 12.7-13.25 GHz, while seeking input on sharing options for the 12.2-12.7 GHz band [1]. This column will provide a brief overview of the recent developments in 12 GHz.
