Advancing Innovation and Reinvigorating Widespread Access to Viable Electromagnetic Spectrum Act or the AIRWAVES Act This bill requires the Federal Communications Commission (FCC) to complete auctions by December 31, 2020, that will grant priority access broadcast licenses for specified frequency spectrum bands. The FCC and the National Telecommunications and Information Administration are directed to identify frequencies in specified spectrum bands that may be utilized for non-federal unlicensed use and commercial licensed use. The FCC must allocate 10% of proceeds from each of the spectrum band auctions specified in the bill to expand wireless infrastructure in rural areas that are underserved or unserved. The FCC shall conduct a study on how unlicensed frequency spectrum bands can be utilized for: (1) the provision of healthcare in rural areas, (2) distance learning, and (3) facilitating innovations in agriculture.
