TL;DR
The FCC has announced a vote on July 22 to auction 160 MHz of spectrum in the Upper C-band, part of a broader effort to expand mid-band wireless capacity. The auction aims to generate significant revenue and support 5G deployment, with details on costs and implementation still to be finalized.
The Federal Communications Commission has announced a vote scheduled for July 22, 2023, on plans to auction 160 megahertz of spectrum in the Upper C-band next year. This move is part of the FCC’s broader effort to expand mid-band spectrum for wireless services, aligning with legal mandates and industry demands. The auction aims to generate billions in revenue and accelerate 5G deployment across the United States.
FCC Chair Brendan Carr confirmed that the upcoming vote will approve a plan to auction 160 MHz of spectrum in the Upper C-band (3.98-4.14 GHz), exceeding the minimum 100 MHz required by the 2025 Working Families Tax Cut Act. This auction will create a contiguous 440 MHz spectrum block when combined with the previously freed Lower C-band (3.7-3.98 GHz). The agency estimates the auction could raise many billions of dollars for the U.S. Treasury.
Stakeholders such as satellite operators estimate transition costs around $3.6 billion, but the FCC has not yet released detailed cost estimates. The agency plans to allocate the spectrum starting in December 2030 in top markets and July 2031 nationwide, with license winners responsible for transition and upgrade costs, including rebates for radio altimeter upgrades.
The FCC emphasizes that this auction will facilitate massive gains in GDP, jobs, and consumer surplus, while also coordinating with aviation authorities to protect aircraft altimeters from interference. The FAA has expressed confidence that with safeguards, 5G deployment can coexist safely with aviation systems.
Impacts on Wireless Expansion and Revenue Generation
This auction represents a significant step in expanding mid-band spectrum access for 5G services, which are critical for faster, more reliable wireless connectivity. The move is expected to generate substantial revenue for the U.S. government, support economic growth, and create jobs. It also highlights ongoing efforts to balance wireless deployment with aviation safety, as the FAA works to ensure coexistence without compromising aircraft safety systems.

Background on Spectrum Reallocation and FCC Initiatives
The FCC has been gradually reallocating spectrum to meet rising demand for wireless services, with recent efforts focusing on the C-band for 5G. The 2021 auction of the Lower C-band freed up 280 MHz, and this upcoming auction in 2024 aims to add an additional 160 MHz in the Upper C-band, creating a continuous 440 MHz block for flexible wireless use. The legal mandate from Congress in 2025 set a minimum of 100 MHz for auction, which the FCC now plans to exceed.
Industry stakeholders, including satellite operators and broadcasters, have expressed concerns about the costs and impact on existing services, but the FCC emphasizes that safeguards and transition plans will mitigate disruptions. The effort also involves coordination with aviation authorities to prevent interference with aircraft altimeters, critical for flight safety.
“We have coordinated with aviation and satellite stakeholders so that wireless providers can light up the Upper C-Band and provide service to most Americans by the end of 2030.”
— FCC Chair Brendan Carr

Next Steps in FCC Spectrum Auction Process
The FCC will hold its vote on July 22, 2023, approving the auction plan. Following approval, the agency will publish detailed rules and cost estimates, with the auction scheduled for 2024. Stakeholders, including satellite operators and wireless providers, will prepare for the transition, which is expected to begin in late 2030 in major markets. The FAA will also finalize its rules for aircraft altimeter upgrades later this summer.
