FCC and NTIA Announce Joint 3.45 GHz Coordination Details

In March 2021, the Federal Communications Commission announced a planned auction of new flexible-use licenses in the 3.45-3.55 GHz band (Auction 110). Auction 110 will offer 4,060 new licenses throughout the contiguous US, subject to cooperative sharing requirements in certain, defined areas where and when federal incumbents require continued access to the band. The FCC, the National Telecommunications and Information Administration (NTIA), and the Department of Defense (DoD) are working collaboratively towards these goals. By this Public Notice, the FCC and NTIA, provide (i) information for potential bidders in the 3.45 GHz Service auction and (ii) guidance to the ultimate 3.45 GHz Service licensees and the affected federal incumbents regarding coordination procedures for shared use of the 3.45 GHz band. The joint nature of this Public Notice reflects the intersecting jurisdictions of the FCC (which administers spectrum for non-federal uses) and NTIA (which administers spectrum for federal uses) in the radio spectrum, including in this band.
