The '''ITU Radiocommunication Sector''' ('''ITU-R''') is one of the three sectors (divisions or units) of the [[International Telecommunication Union]] (ITU) and is responsible for [[radio communications]]. 

Its role is to manage the international [[radio-frequency spectrum]] and [[satellite orbit]] resources and to develop standards for [[radiocommunication]] systems with the objective of ensuring the effective use of the [[spectrum]].<ref>{{cite web|title=Radiocommunication Sector|url=http://www.itu.int/net/about/itu-r.aspx|publisher=[[International Telecommunication Union]]|access-date=2011-03-20|archive-date=2009-05-05|archive-url=https://web.archive.org/web/20090505205254/http://www.itu.int/net/about/itu-r.aspx|url-status=dead}}</ref>

[[ITU]] is required, according to its constitution, to allocate spectrum and register [[frequency allocation]], [[orbital positions]] and other parameters of [[satellites]], "in order to avoid harmful interference between radio stations of different countries". The international [[spectrum management]] system is therefore based on regulatory procedures for [[frequency coordination]], notification and registration.

ITU-R has a permanent secretariat, the Radiocommunication Bureau, based at the ITU HQ in [[Geneva]], [[Switzerland]]. The elected Director of the Bureau is Mario Maniewicz; he was first elected by the ITU membership to the directorship in 2018.

== History ==
{{Anchor|CCIR}}
The '''CCIR'''—'''Comité consultatif international pour la radio''', '''Consultative Committee on International Radio''' or '''International Radio Consultative Committee'''—was founded in 1927.

In 1932 the CCIR and several other organizations (including the original [[ITU]], which had been founded as the International Telegraph Union in 1865), merged to form what would in 1934 become known as the International Telecommunication Union.  In 1992, the CCIR became the ITU-R.
