ITU-R Recommendations Used by spectrum planners and system designers Some referred to in the Radio Regulations Over 900 Recommendations in 16 series The ITU-R Recommendations constitute a set of international technical standards. 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 broadcasting; radiowave propagation; systems and networks for the fixed-satellite service, the fixed and the mobile services; 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.

ITU-R Handbooks Tutorial in nature Liaison with ITU-D (and ITU-T) Continuing Handbook programme in ITU-R Over 30 Handbooks published ITU-R Handbook is a text which provides a statement of the current knowledge, the present position of studies, or of good operating or technical practice, in certain aspects of radiocommunications, which should be addressed to a radio engineer, system planner or operating official who plans, designs or uses radio services or systems, paying particular attention to the requirements of developing countries. It is self-contained, require no familiarity with other ITU Radiocommunication texts or procedures, but does not duplicate the scope and content of publications readily available outside the ITU.
