ITU-R Recommendations

The ITU-R Recommendations constitute a set of international technical standards developed by the Radiocommunication Sector (formerly CCIR) of the ITU. They are the result of studies undertaken by Radiocommunication Study Groups on:
  • the use of a vast range of wireless services, including popular new mobile communication technologies:
  • the management of the radio-frequency spectrum and satellite orbits;
  • the efficient use of the radio-frequency spectrum by all radiocommunication services ;
  • terrestrial and satellite radiocommunication broadcasting;
  • radiowave propagation;
  • systems and networks for the fixed-satellite service, for the fixed service and the mobile service;
  • space operation, Earth exploration-satellite, meteorological-satellite and radio astronomy services.

The ITU-R Recommendations are approved by ITU Member States. Their implementation is not mandatory; however, as they are developed by experts from administrations, operators, the industry and other organizations dealing with radiocommunication matters from all over the world, they enjoy a high reputation and are implemented worldwide.

Free online access to all current ITU-R Recommendations and Reports is now provided to the general public.
