• International Spectrum Regulation – International Telecommunications Union (ITU)
• ITU-R - Radiocommunication Sector - manages use of RF spectrum • ITU-T - Telecommunication Standardization Sector • ITU-D - Telecommunication Development Sector
• National Spectrum Regulation – Federal Communications Commission (FCC)
• Established 1934 by Title 47 of the U.S. Code • Broad regulatory authority in wire-line and wireless
– National Telecommunications and Information Administration • Section 305 powers of President • Assistant Secretary of Commerce for Communications and Information • Federal Government • Foreign embassies in Washington, D.C.
– Interdepartment Radio Advisory Committee (IRAC) • Coordination and liaison
