The Advancing American Wi-Fi Against Foreign Adversaries Act requires the Secretary of Commerce to develop a comprehensive plan within 180 days on how the United States will promote Wi-Fi and other unlicensed wireless technologies globally, particularly ahead of the International Telecommunication Union's World Radiocommunication Conference scheduled for Shanghai in October-November 2027. The bill reflects congressional concern that countries like China are pushing policies at international forums to undermine Wi-Fi technology and force reliance on foreign-controlled telecommunications infrastructure, and it aims to ensure the United States maintains its technological leadership in this sector, which contributes over $1 trillion annually to the economy. The plan must include strategies to counter efforts by adversaries to undermine unlicensed technologies and should promote global harmonization of specific Wi-Fi spectrum bands, with coordination among the Commerce Department, Federal Communications Commission, State Department, and other relevant federal agencies. The legislation also requires a follow-up report within 90 days after the 2027 conference concludes, detailing how well the implementation plan succeeded. The bill does not specify new funding or create new budget authority.
