The FCC, NTIA, and the U.S. Navy have collaborated to expand spectrum sharing in the 3.5 GHz band. Modifications to the aggregate interference model used in the 3.5 GHz band would allow the Citizens Broadband Radio Service (CBRS) to provide uninterrupted access to mid-band spectrum that supports wireless internet and other services to approximately 72 million more people, officials said.

After coordination with the Navy and the FCC, NTIA formally submitted a request to change the aggregate interference model to the FCC this week. The FCC endorsed the changes yesterday and invited Spectrum Access System administrators to submit demonstrations of their ability to implement the modified protection criteria.
