World Radiocommunication Conference

The World Radiocommunication Conference (English World Radiocommunication Conference, WRC) decides on the international level on the needs of the airwaves. The World Radiocommunication Conference Held since 1995 every two to four years; the usual also in the German abbreviation for a particular conference is eg WRC -07 for the World Radiocommunication Conference 2007.

Agenda

To a world radiocommunication conference the definition studies to be undertaken is as much as the definition of radio operating procedures, establishing qualification requirements for radio personnel, as well as the allocation of frequency bands to the various radio services, such as maritime mobile, aeronautical radio service, broadcasting service or the amateur service.

Organizers of the World Radiocommunication Conference is the International Telecommunication Union ( ITU ), an agency of the United Nations. Participants are the ITU Member States. In Germany, the agency responsible for the Radiocommunication authority is the Federal Ministry of Economics and Technology (BMWi ) and the Federal Network Agency in the business. The Economics Ministry has set up in preparation for the WRC, the self-directed by the BMWi National Group in preparation for the World Radiocommunication Conference ( NG). The WRC also at a participating stakeholders of radio spectrum users or industry, such as NATO, EBU or IARU, have no voice.

The overall result of World Radiocommunication Conference is the Radio Regulations Radio Regulations ( Radio Regulations ), which is updated by.

History

At the beginning of the use of radio equipment in the year 1900, the operators subject to any conditions or restrictions. With the widespread use of radio equipment and the ability to bridge long distances by radio, soon resulted in the need for international coordination.

Preparatory Funktelegrafiekonferenz, Berlin 1903

At the invitation of the German government, representatives of the countries Germany, Austria, Spain, United States of America, France, Hungary, Russia, Italy and the United Kingdom in Berlin held a preparatory Funktelegrafiekonferenz (Preliminary conference on wireless telegraphy ) met. This conference, which was not an official event of the International Telecommunication Union, had the goal to provide a fundamental basis for radio- telegraphic arrangements, which should then enter into an international agreement later. Subject of the conference were agreements on the marine radio. Today, this gathering is generally regarded as the first conference in the series of World Radiocommunication Conferences. The adopted on August 13, 1903 Final Minutes of the conference included eight articles on two sides. The UK delegation entered a reservation against the basic outcome of the conference, the Italian delegation had reservations about some articles of the Final Protocol. These reservations are designed to protect the interests of the companies operated by the Italian Guglielmo Marconi Marconi Company in England, which held as Seefunkdienstleister a virtual monopoly.

International Funktelegrafiekonferenz, Berlin 1906

At this second international radio conference, which was held in Berlin from October 3 to November 3, 1906, delegations participated from 27 countries already. The Parties to the Preparatory Funktelegrafiekonferenz 1903, now representatives of Argentina, Belgium, Brazil, Bulgaria, Chile, Denmark, Greece, Japan, Mexico, Monaco, Norway, the Netherlands, Persia, Portugal, Romania, Sweden, Turkey and Uruguay had been joined. Like the previous conference in 1903 was also the conference is still no official Conference of the International Telecommunication Union. The result of the conference, which in turn dealt with marine radio, namely, adopted on November 3, 1906 International radio telegraph contract was the first international radio treaty (English International Wireless Telegraph Convention ). Apart from the actual contract, the Conference adopted a Final Protocol (Final Protocol), an additional agreement (Additional Agreement) as well as provisions on the radio traffic (Service Regulations ).

An economically important outcome of the conference, included in the supplementary agreement was binding agreement on a non-discriminatory implementation of the radio traffic, regardless of which radio system ( Marconi or other ) was used in each case. For the safety at sea, the introduction of the SOS distress character was an important step. The internationally standardized and thus expeditious handling of Seefunkverkehrs served the agreement known as traffic signs, which marked the beginning and end, for example, a press release or the other station transmitted the request to send. The wavelengths were 300 m (corresponding to a frequency of 1 MHz, primarily for use by ships) and 600 m set (corresponding to a frequency of 500 kHz) than that to be used for the public messaging wavelengths.

The International Telecommunication Union celebrated on 30 October 2006 in a ceremony to mark the centenary of the conference and the one hundred anniversary of the Radio Regulations Radio Regulations.

Third Administrative Radio Conference, London 1912

The third conference was dominated by the sinking of the RMS Titanic / Titanic. In the investigation of the sinking material deficiencies in the operation of the ships were detected with radio equipment with each other, there was no uniform operating times, etc. Thus, for example, was the subject of the equipped with Marconi equipment stations to associate only with each other. This was necessary because the public telegraphy was a legal monopoly of the British Post Office.

The conference brought together 45 states and dependent territories in part: Argentina, Australia, Belgium, Belgian Congo, Bosnia - Herzegovina, Brazil, British India, Bulgaria, Chile, Denmark, Germany, Formosa, France and Algeria, French Equatorial Africa, French Indochina, French West Africa, Greece, Great Britain, Italy, Japan and Korea, Japanese Sakhalin and Kwantung, Canada, Madagascar, Morocco, Monaco, New Zealand, the Netherlands, Dutch East Indies and Curacao, Norway, Austria, Persia, Portugal, Romania, Russia, San Marino, Sweden, Siam, Spain, the Union of South Africa, Tunisia, Turkey, Uruguay and the United States.

The new treaty contained 23 articles, the protocol had dreri paragraphs and the Service Regulations contained 50 articles, including the International Morse Code, Q - groups and many useful provisions.

The predecessor of the WRC until 1982, the World Administrative Radio Conference (WARC ).

WARC SAT -77

WARC SAT -77 from January 10 to February 13, 1977 in Geneva, the participants adopted a worldwide broadcasting satellites plan. For 112 applicant countries the geostationary orbital positions were set for the future broadcasting satellites in space. January 1, 1979 was an agreement with a term of 15 years, which provided that could radiate five television programs or more radio programs directly from the satellite to each participant country. The Direct Broadcasting Satellite ( DBS ) should be positioned at 36,000 km with a spacing of 6 ° (approx. 4415 km ) above the equator. A common position 19 ° West has been allocated and used, inter alia, through TV SAT Belgium, the Federal Republic of Germany, France, Holland, Italy, Luxembourg, Austria and Switzerland.

WARC 1979

At WARC- 79 the amateur radio service three new shortwave bands ( WARC bands ) have been allocated.
