A US federal spectrum auction has closed with $3.5 billion in gross proceeds, with all of the revenue earmarked for the program that pays carriers to remove Chinese-made telecom equipment from their networks.

Where will the $3.5 billion go?

The money flows to the Federal Communications Commission's Secure and Trusted Communications Networks Reimbursement Program, popularly known as the rip and replace initiative. Congress created the program under the Secure and Trusted Communications Networks Act of 2019 and expanded it in 2021. The FCC administers the funds day-to-day.

Carriers that bought network equipment from manufacturers the US government has designated as national-security threats can apply for reimbursements covering the cost of swapping in approved alternatives. Both the Trump and Biden administrations named Huawei Technologies and ZTE as covered vendors; the FCC maintains the official Covered List.

What counts as eligible replacement work?

Covered costs include replacement radio, baseband, mobile core and optical transmission gear, plus the labour for site visits, installation and integration. Carriers can recover some software re-engineering and backhaul reconfiguration costs tied directly to the swap.

Recipients must certify disposal of replaced Chinese-made equipment and document which alternative vendor they bought from. Approved alternative suppliers on the US market include Ericsson, Nokia, Samsung Networks and a handful of smaller vendors.

Who benefits from the program?

Smaller and rural operators make up the largest applicant pool. Huawei and ZTE priced their radios and mobile core systems below Western competitors, an attractive proposition for carriers with limited capital serving dispersed customer bases. The program covers fixed-line and wireless operators that bought gear from the named Chinese vendors before designation.

The three largest US national carriers — AT&T, Verizon and T-Mobile US — sourced their radio access networks from Ericsson, Nokia and Samsung well before the rip-and-replace regime started, so they have limited exposure. Their FCC filings focus on legacy packet-optical and select core equipment in particular markets.

How has the funding grown?

Congress first authorised $1.9 billion for the program. As carrier claims exceeded that figure, lawmakers redirected revenue from prior spectrum sales into the pool, lifting available funding well above the original appropriation. The latest $3.5 billion tranche is the largest single revenue line item dedicated to the program to date.

Even with the new money, total allocation could still fall short of operator submissions. The FCC has signalled that it may prorate reimbursements or sequence payouts across multiple years if claims again outpace the pot, prioritising smaller operators and rural communities when rationing.

What is the regulatory backdrop?

The rip-and-replace program sits inside a broader US push to limit Chinese-origin kit in critical communications infrastructure. The FCC has placed Huawei and ZTE on its Covered List; the Commerce Department restricts Chinese equipment in connected vehicles; a separate inter-agency process governs submarine cable landings. Each step widens the list of equipment categories and operators subject to review.

Carriers receiving program funds must also meet ongoing reporting requirements: certification of disposed gear, vendor disclosures and FCC compliance updates.

What happens next?

The FCC must publish a disbursement schedule and any rationing methodology for the $3.5 billion. Industry filings suggest the agency will stage payouts over multiple rounds as carriers continue to submit certified claims, with the first tranches unlikely to clear most applicants in a single cycle.

Future spectrum auctions remain the most likely near-term funding source for additional top-ups, though Congress has been willing to pass supplemental appropriations when claims outrun auction revenue.

A clear view of how the new pot is allocated — and which carriers receive full versus partial reimbursements — will shape the pace of replacement network rollouts across rural US markets for the rest of this decade.
