International Telecommunications Union

A specialized agency of the United Nations with responsibilities for developing operational procedures and technical standards for the use of the radio frequency spectrum, the satellite orbit, and for the international public telephone and telegraph network. There are over 160 member nations of the ITU. The Radio Regulations that result from ITU conferences have treaty status and provide the principal guidelines for world telecommunications. In the case of the U.S., they are the framework for development of the U.S. national frequency allocations and regulations.

The ITU has four permanent organs:

  • the General Secretariat,
  • the International Frequency Registration Board (IFRB),
  • the International Radio Consultative Committee (CCIR),
  • the International Telegraph and Telephone and Consultative Committee (ITTCC).
