Accessible, Affordable Internet for All Act This bill reauthorizes through FY2026, revises, and establishes grants and activities to promote access to broadband internet and other telecommunication services. The bill addresses digital equity and inclusion through grants and by requiring studies on barriers to adoption of broadband services and related matters. The bill addresses broadband affordability and access. It (1) reauthorizes and expands various programs that subsidize or otherwise support broadband services for eligible households, schools and libraries, and tribal lands and populations; and (2) establishes a program for expanding broadband service for underserved areas and community support organizations (e.g., schools and religious organizations). Additionally, the Federal Communications Commission (FCC) must award grants and take other actions to expand programs that verify an individual's eligibility for subsidized services. The bill addresses broadband data collection, disclosure, and sharing. The FCC must (1) issue rules regarding the collection of pricing data and labels that disclose information about broadband plans to consumers, and (2) collaborate and share data with federal agencies and other stakeholders. The bill makes financing (e.g., low-interest loans) available to communities and public-private partnerships for broadband infrastructure investments. Additionally, the Department of Transportation must require states to install conduits for broadband cables as part of certain highway projects. The bill also sets up a task force on nationwide dig once requirements (i.e., policies or practices to minimize excavations of highway rights-of-way when installing telecommunications infrastructure). Further, the bill preempts state laws that prohibit certain telecommunications service providers (e.g., public providers) from providing high-speed broadband services.
