The Federal Highway Administration warned that some foreign-made inverters and battery management systems used for signs, cameras, EV chargers, and other roadside infrastructure contain hidden cellular radios. Officials advised inventorying devices, running spectrum scans to detect unexpected communications, disabling/removing radios, and segmenting networks. This shifts infrastructure security from software-only checks to detecting covert RF channels in hardware.
— Treating power electronics and batteries as potential comms backdoors reframes supply‑chain security and could drive new procurement rules and audits across critical infrastructure.

Both pieces surface hidden communications‑security risks in critical infrastructure: the article shows satellite backhaul leaking calls, texts, utility and military data without encryption; the existing idea exposes undisclosed radios in deployed highway equipment. Together they underscore governance gaps where paperwork and legacy practices mask real comms vulnerabilities.

Both stories address U.S. policy responses to security risks from foreign-made electronics: previously, FHWA warned of hidden cellular radios in roadside equipment; here, the FCC forces retailers to remove prohibited Chinese devices (e.g., Hikvision cameras) and install processes to prevent re-listing on national‑security grounds.
