This bill tells the Assistant Secretary of Commerce for Communications and Information to review how federal agencies use the electromagnetic spectrum and report the findings to Congress within 18 months of the law taking effect. The report must be unclassified (with an optional classified annex) and be available to any Member of Congress who asks.

The report has to list each specific band used by each agency, what it’s used for and how much, where it’s used, whether it’s used only by that agency or shared with others, and which parts aren’t being used at all. The Assistant Secretary must also coordinate with the Department of Transportation so this work doesn’t duplicate a separate audit required by the infrastructure law.

• Who is affected: The Assistant Secretary of Commerce for Communications and Information and all federal agencies that use spectrum.
• What changes: A one-time audit of federal spectrum use and a detailed report to Congress, with information on usage, location, sharing, and unused portions.
• When: Report due within 18 months after the law is enacted.
