• 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

Spectrum Regulation

• Frequency Ranges Allocated By – Geographic Region – Radio Service

• 34 different types • Radar (Radiolocation) • Fixed • Mobile • Broadcasting • Various satellite services

– Additional rules as needed (footnotes)

• Allocations continually evolve to meet evolving domestic and international needs
