The International Telecommunication Union (ITU) is the United Nations specialised agency responsible for information and communication technologies, coordinating global use of the radio spectrum and satellite orbits, developing technical standards and working to expand connectivity worldwide. Through its sectors for radiocommunication, standardization and development it produces recommendations that underpin interoperable telecommunications infrastructure. It is one of the principal international bodies governing the global telecommunications system.
Overview
- The ITU operates through three sectors: ITU-R, which manages the international radio-frequency spectrum and satellite orbital slots; ITU-T, which produces telecommunications standards known as Recommendations; and ITU-D, which promotes equitable access and development. Its work coordinates spectrum across national borders, harmonises technical standards for networks and devices, and shapes policy that affects everything from mobile networks to satellite communications.
Key aspects
- Radiocommunication sector managing global spectrum and orbital resources
