WASHINGTON: U.S. Sens. Olympia J. Snowe (R-Maine) and Mark Warner (D-Va.) have re-introduced legislation to inventory the airwaves. The pair have resurrected the “Radio Spectrum Inventory Act, which directs the National Telecommunications and Information Administration and the Federal Communications Commission “to create a comprehensive inventory of each spectrum band,” how it’s being used and by whom. It would also create a central website “that would include relevant spectrum and license information accessible by the public.”
