Of that, 500 megahertz will have to be federal spectrum identified for reallocation by the National Telecommunications and Information Administration, which manages federal spectrum use. The agency has to find at least 200 megahertz of that by July 2027, and the rest by July 2029.

The remaining 300 megahertz can come from anywhere, although if NTIA finds more federal spectrum than is required it could count toward the total. The FCC has to finish an auction of at least 100 megahertz in the upper C-band by July 2027, which FCC Chairman Brendan Carr has said will be a heavy lift.
