  The ITU Radio Regulations (short: RR) is a basic document of the International Telecommunication Union (ITU) that regulates on law of nations scale radiocommunication services and the utilisation of radio frequencies. It is the supplementation to the ITU Constitution and Convention and in line with the ITU International Telecommunication Regulations (ITR). The ITU RR comprise and regulate the part of the allocated electromagnetic spectrum (also: radio frequency spectrum) from 9 kHz to 300 GHz.

  ## Definitions
  
  The Radio Regulations define:
  
  * the allocation of different frequency bands to different radio services;
  * the mandatory technical parameters to be observed by radio stations, especially transmitters;
  * procedures for the coordination (ensuring technical compatibility) and notification (formal recording and protection in the Master International Frequency Register) of frequency assignments made to radio stations by national governments;
  * other procedures and operational provisions.
  
  ## Update
  
  The drafting, revision and adoption of the Radio Regulations is the responsibility of the World Radiocommunication Conferences (WRCs) of the ITU, meetings of which are typically held every three or four years.
  
  Recent WRCs are:
  
  * Geneva, 1995 (WRC-95)
  * Geneva, 1997 (WRC-97))
  * Istanbul, 2000 (WRC-2000)
  * Geneva, 2003 (WRC-03)
  * Geneva, 2007 (WRC-07)
  * Geneva, 2012 (WRC-12)
  * Geneva, 2015 (WRC-15)
  * Sharm el-Sheikh, 2019 (WRC-19)
  
  The most recent published version of the Radio Regulations, the "Edition of 2016" contains the complete texts of the Radio Regulations as adopted and revised by WRC-15, including all articles, appendices, resolutions, and a subset of the recommendations issued by ITU-R (previously known as the CCIR) (those "recommendations" which have a mandatory nature, as a result of being cited in the Radio Regulations).
  
  The "Edition of 2020", adopted and reviewed by the WRC-19, is scheduled for publication in October 2020.
