The Trump administration is debating whether to ban Chinese-made “cellular modules” as the Federal Communications Commission (FCC) intensifies its broader crackdown on Chinese communications and consumer electronics technologies over mounting national security concerns, the Financial Times reports. The claim comes ahead of this week’s meeting between US President Donald Trump and Chinese President Xi Jinping in Beijing, where the two leaders are expected to discuss trade tensions, technology restrictions, and the fragile truce reached after their October summit in South Korea.
Cellular modules are small, embedded communication components that enable devices to connect to mobile networks such as 4G and 5G without relying on Wi-Fi. They are used in everything from smart home devices, industrial sensors, routers, drones, and medical systems to connected cars, logistics trackers, and factory equipment. A ban would therefore extend far beyond smartphones and telecom infrastructure, potentially affecting huge portions of the global IoT and connected-device supply chain.
According to the report, the administration’s debate centers on whether Chinese module makers should eventually be added to the FCC’s “Covered List,” which bars products deemed to pose national security risks from obtaining FCC authorization to be sold in the United States.
The potential move would mark the latest escalation in a years-long U.S. campaign of managing potential risks from Chinese communications technology firms. Under FCC chair Brendan Carr, the agency has increasingly positioned itself as one of Washington’s most aggressive regulators on China-related technology security issues.
Just last month, the FCC voted to proceed with a proposal banning Chinese laboratories from conducting mandatory testing required for consumer electronics certification in the US. The proposal could affect everything from smartphones and routers to baby monitors and Bluetooth devices. According to the report, roughly 75% of testing for the approximately 40,000 devices certified annually by the FCC is currently conducted in China. The FCC has also recently moved against Chinese-made drones and internet routers, arguing that Chinese communications hardware could pose espionage and surveillance risks.
The concerns surrounding cellular modules are particularly significant because the components require periodic firmware and software updates, creating what some security experts believe could become potential pathways for remote access, surveillance, or tampering. According to the report, Chinese companies, including Quectel, Fibocom, China Mobile, Sunsea, and MeiG, collectively control more than 70% of the global cellular module market.
The FCC seems to be pushing ahead with restrictions despite the broader US-China trade truce reached after Trump’s October meeting with Xi, even as other agencies had reportedly slowed or paused some China-related actions in recent months to avoid destabilizing negotiations.
According to the report, Carr created a national security council within the FCC last year specifically to address threats from “foreign adversaries,” particularly China. FCC officials cited in the report argued that modern communications devices — including Wi-Fi and Bluetooth-enabled consumer electronics — increasingly represent both technological and geopolitical attack surfaces.
While no formal ban on cellular modules has been announced, its actualization could have a tremendous impact on the electronics industry, given how deeply Chinese-made connectivity components are embedded across global supply chains. Eventual restrictions could force manufacturers to redesign products, shift suppliers, or rebuild certification and sourcing pipelines at an enormous scale.
