USA - In the Matter of Upper C-band (3.98-4.2 GHz)

​The Federal Communications Commission (FCC) is proposing rule changes to expand next-generation wireless services in the 3.7-4.2 GHz C-band by making 100-180 MHz of the Upper C-band (3.98-4.2 GHz) available for terrestrial wireless use through competitive bidding, as directed by the One Big Beautiful Bill Act (OBBB Act). The FCC seeks input on reconfiguring the band, transitioning incumbent Fixed Satellite Service (FSS) operators, and ensuring co-existence with adjacent band radio altimeters, while applying existing 3.7 GHz Service rules to the new operations. The proposal also addresses reallocation, auction procedures, licensing, and technical rules to facilitate the transition and maximize the use of the spectrum for wireless services.
