This report from the Government Accountability Office (GAO), published in September 2021, explains the steps the FCC is taking to improve the accuracy of its broadband deployment mapping, as required by the 2020 Broadband DATA Act. The GAO reviewed relevant statutes, regulations, FCC documents, and its own work on broadband mapping; interviewed federal officials and representatives from the telecommunications industry; and researched how all states and territories are gathering their mapping data.
