ITU-R stands for International Telecommunication Union, Radiocommunication Sector (translation: Internationale Fernmeldeunion - Funkkommunikation) and is one of three sectors of the International Telecommunication Union (ITU) with responsibility for international matters in the field of radio communication . The forerunner organization until 1992 was the International Advisory Committee for Radiocommunications (fr: Comité Consultatif International des Radiocommunications CCIR).
assignment
The ITU-R sector is tasked with carrying out studies and issuing recommendations on technical and operational issues that specifically affect radio communication, without restrictions on the frequency ranges. As a rule, economic issues are not considered in these studies, but in cases where the studies require comparisons between several technical solutions, economic factors may also be taken into account.
The responsibility of this sector includes the areas of space radio services , terrestrial radio services and the regulations for radio services (VO radio), including the associated study groups.
Space communications services
The area of space radio services includes international coordination (coordination of the orbit position of the space station and frequency coordination), coordination and verification management for space radio systems and earth stations . This includes engineering studies and reviews of frequency allocations of spectrum management (ITU member countries) and the processing of applications, for receiving frequency assignments in the International Frequency main tab ( English - Master International Frequency Register (MIFR) ).
Terrestrial radio services
These areas include international coordination, coordination and verification for terrestrial radio systems. This also includes the engineering investigation and evaluation of frequency assignments by the frequency administrations (from ITU member countries), the processing of applications for the inclusion of frequency assignments in the MIFR and the relevant frequency allotment plans or channel distribution plans.
The division also has administrative regulations regarding the allocation of international means for identification (call sign series, MIDs) and for safety-relevant (en: safety of life) applications. This also includes the specialist publication service with the associated online services.
VO radio
The VO Funk (en: Radio Regulations [RR]) contains the decisions of the world radio conferences , including the appendices, resolutions, recommendations and ITU-R recommendations to which reference is made.
The ITUR-R rules of procedure have been approved by the Radio Regulations Board (RRB), which are part of the Radio Regulations. It creates legal certainty with regard to the application of special regulations and leaves room for discretion, unless a practicable solution is provided in individual cases.
ITU-R study groups
Worldwide, more than 5,000 experts from telecommunications organizations, information and communication technology (ICT) organizations and frequency administrations participate in study groups for radio communication (en: Radiocommunication Study Groups). Her responsibilities include the field professionally sound preparation of World Radiocommunication Conferences , Development of ITU-R Recommendations (standards for radio communications) and Gutachte and the publication of manuals for radio communication (s: radio communication Handbooks). The ITU-R sector has various study groups (SG) with the associated working groups (AG), which are exemplified below.
These also deal with specific radio applications such as International Mobile Telecommunications (IMT) and wireless access in the field of fixed radio service , amateur radio service and amateur radio service via satellite .

historical development
The International Advisory Committee for Radio Services (CCIR for short) - Comité consultatif international pour la radio , Consultative Committee on International Radio or International Radio Consultative Committee - was founded in 1927.
In 1932 the CCIR was merged with other organizations, such as the original ITU , which was founded in 1865 under the name International Telegraph Union . From 1934 the new organization was given the name International Telecommunication Union , which is still valid today , while retaining the abbreviation ITU . In 1992 the CCIR was renamed ITU-R.
Today, the ITU-R sector has a permanent secretariat - the Office for Radiocommunications (s: Radiocommunication Bureau) - in the ITU headquarters at Geneva in Switzerland . The current director of the office is the French François Rancy, who was an elected ITU member and was appointed in 2010.
