Should companies be allowed to retire older copper phone networks in favor of fiber or wireless?
FCC Chairman Brendan Carr has proposed federal preemption of California's carrier of last resort regulations to allow AT&T to proceed with decommissioning its copper network. This follows a lawsuit from the company aimed at overriding state requirements that currently impede its transition to fiber and wireless infrastructure.
Why it matters
The conflict highlights a growing national divide between federal efforts to accelerate the retirement of aging copper-based telecommunications infrastructure and state-level mandates designed to protect legacy service requirements for rural and vulnerable populations.
AT&T is targeting the retirement of 360 copper wire centers across California, a move that affects only 1% of its total customer base currently utilizing legacy copper-based voice technology. The company intends to replace these systems with IP-based wireless or fiber alternatives, including its AT&T Phone-Advanced platform designed to maintain support for legacy hardware.
The players
AT&T
A major telecommunications provider currently transitioning its infrastructure stack from legacy copper to fiber-optic and wireless broadband networks.
Brendan Carr
The Chairman of the Federal Communications Commission who is currently seeking to expedite network modernization by limiting state regulatory oversight.
Communications Workers of America
A labor union representing telecommunications workers that is actively opposing the removal of legacy service obligations in California.
The details
AT&T is shifting from copper-based Plain Old Telephone Service (POTS) to IP-based delivery, which uses packet-switched data networks to carry voice traffic. The transition involves decommissioning physical wire centers and replacing them with fiber-to-the-premises or fixed wireless setups. For users reliant on legacy hardware like alarms or medical monitors, the company uses a digital conversion device, AT&T Phone-Advanced, to emulate the signaling of the legacy network while operating on the new fiber backbone.
Timeline
October 22, 2026: Various organizations filed formal opposition to the AT&T petition with the FCC.
June 1, 2027: The earliest possible date for AT&T to initiate decommissioning of California wire centers.
2030: The company’s target date for completing the decommissioning of the bulk of its national copper network.
The Tech Race
The push to decommission copper networks is a national industry shift, with AT&T already having retired services across 500 communities in 18 states. California represents a significant regulatory hurdle in a larger race to finalize the transition to all-fiber and wireless infrastructure by 2030.
Customers in affected California wire center areas may see services migrated to fiber or wireless alternatives if the proposal is approved. Those currently utilizing legacy copper-based equipment should monitor for service transition notices, as the decommissioning process is set to begin no earlier than June 1, 2027.
The takeaway
The FCC's proposal represents a decisive federal attempt to override state-level legacy service requirements in favor of modern fiber networks. Readers should watch for a final FCC ruling following the opposition filed by stakeholder groups on October 22, 2026.
