Spectrum Innovation Act of 2022 This bill addresses auctions of, and other matters related to, portions of the electromagnetic spectrum allocated for federal use. The bill also establishes grants for and otherwise modifies provisions concerning next generation 9-1-1 systems (i.e., interoperable Internet Protocol-based systems for receiving 9-1-1 calls). The bill extends to March 31, 2024, the authority of the Federal Communications Commission (FCC) to auction and license electromagnetic spectrum. (Under current law, the authority expires on September 30, 2022.) Additionally, the bill establishes a process for auctioning specified parts of the spectrum currently allocated for federal use. The Office of Management and Budget must transfer certain funding to federal entities for planning activities related to reallocating and auctioning spectrum while the National Telecommunications and Information Administration (NTIA) and the Executive Office of the President must oversee the planning. The Department of Commerce must, informed by the planning, identify the spectrum to auction. Further, the bill addresses shared use of spectrum bands by federal and nonfederal users. For example, the NTIA must implement an incumbent informing capability system to manage harmful interference when nonfederal users and incumbent federal entities share spectrum. The bill also establishes the Public Safety and Secure Networks Fund and directs a portion of spectrum auction proceeds to the fund for, among other purposes, reimbursing telecommunications providers for replacing equipment that poses risks to national security and safety.
