ITU-R

The ITU Radiocommunication Sector (ITU-R) is one of the three sectors (divisions or units) of the <a href="/facts/International_Telecommunication_Union/Yn8UKKkw">International Telecommunication Union</a> (ITU) and is responsible for <a href="/facts/Radio_communications/XFr909M2">radio communications</a>. 
Its role is to manage the international <a href="/facts/Radio-frequency_spectrum/aWku7h4R">radio-frequency spectrum</a> and <a href="/facts/Satellite_orbit/nD2TPySG">satellite orbit</a> resources and to develop standards for <a href="/facts/Radiocommunication/XFr909M2">radiocommunication</a> systems with the objective of ensuring the effective use of the <a href="/facts/Spectrum/wPUjkpqI">spectrum</a>.
<a href="/facts/ITU/xnT5QSEl">ITU</a> is required, according to its constitution, to allocate spectrum and register <a href="/facts/Frequency_allocation/cFsWaXvF">frequency allocation</a>, orbital positions and other parameters of <a href="/facts/Satellites/PTX8c68t">satellites</a>, "in order to avoid harmful interference between radio stations of different countries". The international <a href="/facts/Spectrum_management/etDs5EYB">spectrum management</a> system is therefore based on regulatory procedures for <a href="/facts/Frequency_coordination/taQ9UtdW">frequency coordination</a>, notification and registration.
ITU-R has a permanent secretariat, the Radiocommunication Bureau, based at the ITU HQ in <a href="/facts/Geneva/14gXxjcq">Geneva</a>, <a href="/facts/Switzerland/LcGuxeTe">Switzerland</a>. The elected Director of the Bureau is Mario Maniewicz; he was first elected by the ITU membership to the directorship in 2018.
