3550-3650 MHz

The Federal Communications Commission (FCC) created the Citizens Broadband Radio Service (CBRS) in the 3550-3650 MHz band in 2015. Since then, NTIA has worked closely with the FCC and the Department of Defense (DOD) to coordinate spectrum sharing among CBRS operators and existing federal users in the band. The sharing approach includes creating Dynamic Protection Areas to protect federal wireless operations from potentially harmful interference by new CBRS systems.

Transition Plans for 3550-3650 MHz Auction 

The FCC has announced plans for a CBRS spectrum auction in the 3550-3650 MHz band. The Commercial Spectrum Enhancement Act enables federal agencies to seek reimbursement for transition costs associated with an auction, and these plans must be made public no later than 120 days before the auction begins. NTIA provided initial estimates of sharing costs to the FCC in December 2019.  These estimated costs were reviewed by OMB and approved by Congress. The final transition plans are listed below.
