ITU-R is the Radiocommunication Sector of the International Telecommunication Union, the United Nations agency responsible for managing the global radio-frequency spectrum and satellite orbits. It coordinates international spectrum allocation, develops technical recommendations and maintains the Radio Regulations treaty that governs cross-border use of radio. ITU-R sets the framework for mobile, broadcasting, satellite and emerging wireless standards, including the IMT specifications that define generations such as 5G.
- ITU-R is the radiocommunication sector of the ITU and a global Standards Organization for radio spectrum.
- It governs international spectrum allocation and the Radio Regulations that underpin Wireless Communication.
- Its IMT recommendations frame mobile generations including 5G and broader Telecommunications.
Overview
- ITU-R exists because radio waves do not stop at borders: without coordinated allocation, transmissions in one country would routinely interfere with services in another. It manages spectrum and satellite orbital slots as shared global resources.
- The sector maintains the Radio Regulations, an international treaty, and issues technical Recommendations covering propagation, broadcasting, fixed and mobile services and satellite systems.
- For mobile networks it defines the IMT family of requirements against which generations such as IMT-2020 (5G) are assessed, giving the industry a common performance and spectrum target.
Key aspects
- Custodianship of the international Radio Regulations treaty.
- Global spectrum allocation and satellite orbital coordination.
- Technical Recommendations for radio propagation and services.
- The IMT framework defining mobile generation requirements.
- World Radiocommunication Conferences that revise allocations.
Applications
- Mobile broadband generation requirements such as 5G IMT-2020.
- Terrestrial and satellite broadcasting allocations.
- Fixed, mobile and satellite service coordination across borders.
