The Federal Communications Commission has identified up to 500 megahertz of mid-band spectrum between 3.7 and 4.2 GHz that could be open for 5G wireless services.
A newly adopted FCC order sets forth several steps toward making more mid-band spectrum available for terrestrial fixed and mobile broadband use. Specifically, the Order will require Fixed Satellite Service earth stations operating in the 3.7-4.2 GHz band to certify the accuracy of existing registration and license information and will collect additional information from space station licensees on their operations in the band to assist the Commission and commenters in developing a clearer understanding of how the band is currently being used. The Commission will then use this information to evaluate the most efficient way to drive the deployment of mid-band spectrum for mobile services and more intensive fixed services.
The FCC said its Notice also proposes to add a mobile (except aeronautical mobile) allocation to all 500 megahertz in the band and seeks comment on various proposals for transitioning part or all of the band for flexible use, working up from 3.7 GHz, including market-based, auction, and alternative mechanisms. The Notice also seeks comment on allowing more intensive point-to-multipoint fixed use in some portion of the band, on a shared basis, working down from 4.2 GHz and on how to define and protect incumbent users from harmful interference, and it seeks comment on service and technical rules that would enable efficient and intensive use by any new services in the band.
“Our focus here is on making more intensive use of the 3.7-4.2 GHz band, commonly called the C-band. To help us figure out the best way forward, we authorize the collection of additional information from the band’s current users. That data will help us figure out how to accommodate the needs of incumbents, which are primarily using the band to provide Fixed Satellite Service. It’ll also enable us to free up more spectrum for advanced wireless services,” stated FCC Chairman Ajit Pai.
