radio spectrum pollution
Radio spectrum pollution is the straying of waves in the radio and electromagnetic spectrums outside their allocations that cause problems for some activities. It is of particular concern to radio astronomers.
Radio spectrum pollution is mitigated by effective spectrum management. Within the United States, the Communications Act of 1934 grants authority for spectrum management to the President for all federal use (47 U.S.C. 305). The National Telecommunications and Information Administration (NTIA) manages the spectrum for the Federal Government. Its rules are found in the "Manual of Regulations & Procedures for Federal Radio Frequency Management". The Federal Communications Commission (FCC) manages and regulates all domestic non-federal spectrum use (47 U.S.C. 301).〔(【引用サイトリンク】title=FCC: Wireless Telecommunications Bureau: Rules and Regulations )〕 Each country typically has their own spectrum regulatory organization. Internationally, the International Telecommunications Union (ITU) coordinates spectrum policy.
