A US spectrum auction has raised $3.5 billion, with the proceeds set to fund the removal of Chinese telecom equipment from American networks, Reuters reports.

The figure anchors a policy effort that has been running since 2019, when Washington designated Huawei and ZTE as national security threats to US communications networks. That designation pushed carriers — particularly smaller rural operators that relied heavily on inexpensive Chinese gear — to commit to ripping out and replacing the equipment.

Congress created the reimbursement framework to cushion the cost, but funding has fallen short of demand. Carriers that took federal subsidies previously filed claims well above the allocated pot, and the Federal Communications Commission has warned repeatedly about a shortfall that has left some rural operators facing replacement costs they cannot cover.

The $3.5 billion from the auction provides a fresh funding line. Under the legislative design, proceeds from spectrum sales flow into the rip-and-replace program, which pays carriers to swap Huawei and ZTE equipment out of their networks and replace it with gear from non-Chinese suppliers.

The mechanism ties two strands of US telecom policy together: freeing mid-band and other spectrum for commercial 5G use on one hand, and decoupling American networks from Chinese vendors on the other. Both stem from the same security-driven legislative push that has shaped the FCC's agenda over the past several years.

For equipment buyers, the program has effectively reallocated demand toward the remaining major radio and core suppliers — Ericsson, Nokia and Samsung among them — since carriers receiving reimbursement must purchase from the FCC's approved list.

The auction proceeds also land amid broader pressure on spectrum supply. US carriers have repeatedly warned that commercial 5G capacity depends on more mid-band airwaves being released, and congressional negotiations over spectrum pipeline legislation have dragged on over how auction authority — which lapsed in March 2023 — should be restored and what share of proceeds should fund priorities like rip-and-replace and next-generation 911.

Reuters did not report a detailed breakdown of which bidders secured which licenses, nor the specific spectrum bands involved, in the auction tally.

The funding arrives at a consequential moment for the replacement program. The FCC has flagged continued cost overruns, and some rural carriers have said they may shut down service in parts of their footprints if reimbursement gaps persist. How far $3.5 billion stretches against the outstanding claims will determine whether the rip-and-replace effort concludes on schedule or drags into another funding fight on Capitol Hill.
