The Radio Regulations is an intergovernmental treaty text of the International Telecommunication Union (ITU), the Geneva based specialised agency of the United Nations which coordinates and standardises the operation of telecommunication networks and services and advances the development of communications technology. The International Telecommunication Union (ITU; French: Union internationale des télécommunications, Spanish: Unión Internacional de Telecomunicaciones) is an international organization established to standardize and regulate international radio and telecommunications. ... For other uses, see Geneva (disambiguation). ... UN and U.N. redirect here. ...


Covering both legal and technical issues, it serves as a supranational instrument for the optimal international management of the radio spectrum. Radio frequency, or RF, refers to that portion of the electromagnetic spectrum in which electromagnetic waves can be generated by alternating current fed to an antenna. ...


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.

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: World Radiocommunication Conference (WRC) is organized by ITU to review, and, if necessary, revise the Radio Regulations, the international treaty governing the use of the radio-frequency spectrum and the geostationary-satellite and non-geostationary-satellite orbits. ...

The 2004 edition contains the complete texts of the Radio Regulations as adopted and revised by WRC-03, 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). Istanbul (Turkish: , Greek: , historically Byzantium and later Constantinople; see other names) is Turkeys most populous city, and its cultural and financial center. ... The ITU Radiocommunication Sector (ITU-R) is a standards body subcommittee of the International Telecommunication Union (ITU) relating to radio communication. ...

Amateur radio - Wikipedia, the free encyclopedia (5367 words)
In fact, amateur radio's role in public service and international relations is such an integral part of the hobby that the United States Federal Communications Commission has gone so far as to codify some of these items in its amateur radio regulations.
Amateur radio operators who are doctors, engineers, educators, lawyers, entertainers, electricians, farmers, bankers, and government employees (to name a few) have frequently found practical on-the-job applicability to ideas learned through the study of electronics and communications in amateur radio.
The propagation of radio waves at these frequencies, especially during anomalous conditions, is poorly understood, and amateurs lead the way in learning about these, although high absorption of water and oxygen molecules in this region of the electromagnetic spectrum often limits practical uses to kilometres or tens of kilometres.
