Upper C-Band (3.98-4.2 GHz); Expanding Flexible Use of the 3.7 to 4.2 GHz Band
What happened
The Federal Communications Commission (Commission) adopted an Order making 160 megahertz of the 3.98-4.2 GHz band (Upper C-band) available for terrestrial wireless flexible use. This action, signed by Donald Trump, fulfills Congress's directive to complete a competitive bidding system by July 4, 2027, for at least 100 megahertz of this spectrum. New licensees must reimburse incumbent Fixed Satellite Service (FSS) licensees for migration costs and provide rebates to aircraft owners for radio altimeter retrofits.
Why it matters
This action makes more spectrum available for advanced wireless services, potentially improving network capacity and speed. It also ensures coexistence with existing satellite services and aircraft radio altimeters by outlining reimbursement and retrofit requirements, minimizing disruption.
Who it affects
- ›New terrestrial wireless service providers
- ›Incumbent Fixed Satellite Service (FSS) licensees
- ›Space station operators meeting clearing obligations
- ›Aircraft owners and operators
