National Security Risks from Chinese Cell Phone Modules

A recent report from the Foundation for Defense of Democracies highlights a significant national security threat posed by cell phone modules produced by Chinese companies, specifically Quectel and Fibocom. These companies dominate nearly half of the global market for these components, which are integral to connecting smart home devices to cellular networks. Their market control raises serious concerns about potential espionage and sabotage that could seriously impact U.S. national security and infrastructure.

The report discusses how these modules are deeply embedded in everyday smart devices like doorbells, refrigerators, and thermostats, as well as critical infrastructure systems including ports, hospitals, and transportation networks.

One of the main worries is that these manufacturers retain remote access for firmware and software updates. This access could allow them to collect personal data or disable the devices. Given China’s national security regulations, which permit government access to corporate data for surveillance, there is a real risk that the Chinese authorities could gain access to sensitive information about Americans.

“If China tightens its control over U.S.-based modules, it could disrupt U.S. military mobilization in the event of a crisis, such as a potential invasion of Taiwan,” the report warns. The authors also suggest that China might even leverage this dependency to threaten substantial economic disruption in the U.S.

However, the report notes that eliminating the use of these cellular modules isn’t practical, as they are vital for automation and integrating artificial intelligence into our environments. These modules serve as critical links to 4G or 5G networks when Wi-Fi is unavailable.

One report author stated, “The primary concern is that a cellular module within a Wi-Fi modem could gain access to all the information passing through that modem. If this information reaches a Chinese manufacturer, it could be obtained by the Chinese Communist Party.” This is troubling, especially considering previous congressional findings that connect Quectel to China’s military-civil fusion strategy and its ties to the BeiDou satellite navigation system, which supports military operations.

The report raises alarms about how this control could affect U.S. military operations, given the military’s reliance on securely functioning critical infrastructure. “China’s influence over these modules could potentially disrupt systems essential for projecting military power overseas,” another expert noted.

To mitigate these risks, the report puts forth three recommendations. First, Congress should mandate the Department of Defense to audit its infrastructure to identify any embedded Chinese modules. Second, it should bar the Department from acquiring Chinese mobile modules. Lastly, the Federal Communications Commission should place Chinese cellular module manufacturers on a target list, preventing their licensing or sale within the United States.
