FCC Prepares First US Spectrum Auction in Five Years: 160 MHz of Upper C-Band
The FCC will vote on selling 160 MHz of upper C-band spectrum, the first US auction since 2023, with forecasts of $30bn-$75bn for the Treasury.
Spectrum & PolicyWhy it matters
- The FCC plans to vote on auctioning 160 MHz of upper C-band spectrum (3.98-4.14 GHz), the first auction since its authority expired in 2023.
- Analysts estimate the sale could generate between $30 billion and $75 billion for the US Treasury.
- A CTIA-commissioned study estimates each 400 MHz tranche of mid-band spectrum yields about $264 billion in GDP and 1.55 million jobs.
- The One Big Beautiful Bill reauthorized FCC auctions and requires at least 100 MHz identified for auction within a year.
- The FCC's previous 2.5 GHz auction raised $428 million, widely portrayed as underwhelming.
The story
The Federal Communications Commission will vote on authorizing the sale of 160 MHz of spectrum, the first US spectrum auction since the FCC's auction authority expired in 2023. The band in question is the so-called upper C-band, running roughly from 3.98 GHz to 4.14 GHz, currently allocated to satellite operators and aviation users.
The FCC announced the move almost a year after Congress passed the One Big Beautiful Bill (OBBB), which reauthorized FCC spectrum auctions and required the agencies charged with spectrum management to identify at least 100 MHz for auction by this time next year.
Ahead of the Commission's vote, analysts highlighted that releasing the new mid-band could add billions of dollars to the US economy, create millions of jobs and generate between $30 billion and $75 billion for the Treasury.
Those prospective benefits, however, point to a tension at the heart of spectrum auction design: while a sale raises revenue for the US Treasury, the broader economic benefits of releasing more spectrum into the marketplace are what matter.
What could the upper C-band be worth?
A CTIA-commissioned study examined the economic benefits of mid-band spectrum reallocation. Its estimates:
- Each additional 400 MHz tranche of spectrum will, on average, yield approximately $264 billion in GDP
- 1.55 million new jobs per tranche
- Direct benefits to consumers of between $320 billion and $480 billion
Demand pressure on existing bands continues to build. Wireless providers, internet and cable operators, artificial intelligence applications and low-Earth orbit satellite constellations all compete for the spectrum already in use.
Why did auctions stop in the first place?
Congress decided in 1993 to authorize auctions, replacing decades of "beauty contests" — hearings in which prospective users had to argue their case to the Commission. Economists have long described those non-market allocation processes, in place since the FCC took command-and-control management of spectrum in 1927, as inefficient.
But owing to bureaucratic inertia and congressional inaction, the FCC's authority to conduct auctions expired in 2023, leaving much of the resource idle. The OBBB's reauthorization reverses that drought.
Does auction revenue measure success?
Much of the public campaigning around auctions, and much of the professional advice rendered to the FCC, focuses on how much money a sale raises for the government. Economists argue this emphasis is misplaced: the primary value of auctions lies in the benefits they create for consumers by shifting scarce spectrum from low- to higher-valued uses, as revealed by what consumers actually pay for wireless services and devices in retail markets.
The revenue focus was visible in media coverage of the FCC's previous 2.5 GHz auction, which cast the $428 million earned by the government as underwhelming.
The mechanics matter. Since the price of a license represents the present value of the profits that can be earned from owning it, auction prices can be inflated by limiting the amount of bandwidth sold or setting high reserve prices. Such policies may maximize FCC revenues, but they do so at the cost of limiting competition in the marketplace and hurting consumers.
As economists have repeatedly emphasized, the FCC should auction spectrum rights with an eye toward market efficiency, not maximizing auction revenue.
What about full property rights?
The FCC currently auctions "flexible use licenses." These give licensees greater discretion over how they use their frequencies, but still constrain specific bandwidths to specific services. The 1993 legislation authorizing auctions, for example, provided for the sale of bandwidth for use by Personal Communication Service networks only, limiting firms' ability to reallocate bands as technology evolved.
Economists have shown that restricting the use of spectrum licenses limits consumer gains by restricting market competition. Granting licensees full property rights would instead let them determine the highest and best use of their spectrum based on changing market conditions rather than regulatory constraints — and would allow band deployment to shift as technology and demand evolve, including toward 6G.
Barring that, the argument runs, the FCC should simply get as much bandwidth to market in as short a time as possible, allocating spectrum to where it provides the largest benefit to society.
What happens next?
The Commission's vote will determine whether the 160 MHz sale proceeds. Under the OBBB's timeline, the agencies managing spectrum must identify at least 100 MHz for auction within the next year, and the ultimate value of the sale for consumers will depend on how the FCC structures it.
