The Federal Communications Commission is exploring reallocation of part of the upper C-band in the US. In a unanimous vote at its November 20th meeting, the commission studied a draft version of a Notice of Proposed rulemaking which will guide its actions going forward. The FCC will be asking broadcasters and satellite users for comment on a number of options for reallocating 4.0 through 4.2 GHZ before it moves to the competitive-bidding stage no later than July of 2027.

The FCC will also be inviting comment from other users of the C-band who may be using frequencies near the portion being eyed for reallocation.

When the lower half of the C-band was reallocated five years ago, its use was assigned for wireless services. Broadcasters' satellite services were moved from there to the upper half of the band.
