WASHINGTON, Oct. 22, 2025 – The 5G and aviation industries have found some common ground on a future upper C-band auction, several trade groups and companies told the Federal Communications Commission.

In a presentation to 17 agency staff members, officials from both industries said at least 180 megahertz of the band could be opened up for full-power use without interfering with critical airplane components.

“Monthly working sessions have now resulted in substantial common ground for mobile/[radio altimeter] coexistence,” trade groups said in a filing posted Wednesday.
