Preliminary Conference On Wireless Telegraphy
The Preliminary Conference on Wireless Telegraphy, held in Berlin, Germany, in August 1903, reviewed radio communication (then known as "wireless telegraphy") issues, in preparation for the first International Radiotelegraph Convention held three years later. This was the first multinational gathering for discussing the development of worldwide radio standards. Background The immediate cause for the conference was the previous year's ''Deutschland'' incident. Early that year one of the passengers aboard the SS ''Deutschland'', Prince Heinrich of Prussia, brother of the German Kaiser, attempted to send a wireless telegram thanking U.S. President Theodore Roosevelt for his recent hospitality."Objections to Monopoly" ''History of Communications-electronics in the United States Navy'' by Linwood S.

International Radiotelegraph Convention (1906)
The first International Radiotelegraph Convention (French: ''Convention Radiotélégraphique Internationale'') was held in Berlin, Germany, in 1906. It reviewed radio communication (then known as "wireless telegraphy") issues, and was the first major convention to set international standards for ship-to-shore communication. One notable provision was the adoption of Germany's " SOS" distress signal as an international standard. The resulting agreements were signed on November 3, 1906, and became effective on July 1, 1908. These standards remained in effect until they were updated at the second International Radiotelegraph Convention, held in London in 1912. Background The Convention was initiated by Germany, which three years earlier had hosted a Preliminary Conference on Wireless Telegraphy that called for a subsequent formal conclave to expand on the issues discussed at the original conference.

SS Deutschland (1900)
SS ''Deutschland'' was a passenger liner built in Szczecin, Stettin and launched in 1900 by the Hamburg America Line of Germany. The rival Norddeutscher Lloyd, North German Lloyd line had launched Germany's first four funnel liner, in 1897, and SS ''Deutschland'' was built by Hamburg America as Germany's second four-funnel liner in order to compete. Although ''SS Deutschland'' was able to capture the Blue Riband from ''Kaiser Wilhelm der Grosse'', crossing the Atlantic Ocean in just over five days, she suffered from persistent engine issues, and was withdrawn from transatlantic service in 1910 after just ten years. At this time she was renamed ''Viktoria Luise'' and converted to a dedicated cruise ship. As ''Viktoria Luise'' she saw brief service in World War I. Because of the bad condition of the ship after the World War, it was not seized by the Allies and was for a time the only remaining large steam ship sailing under a German flag. In 1921 she was converted again into an immi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marconi Company
The Marconi Company was a British telecommunications and engineering company that did business under that name from 1963 to 1987. Its roots were in the Wireless Telegraph & Signal Company founded by Italian inventor Guglielmo Marconi in 1897, which underwent several changes in name after mergers and acquisitions. The company was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UK's most successful manufacturing companies. In 1999, its defence equipment manufacturing division, Marconi Electronic Systems, merged with British Aerospace (BAe) to form BAE Systems. In 2006, financial difficulties led to the collapse of the remaining company, with the bulk of the business acquired by the Swedish telecommunications company, Ericsson.

Telecommunication Conferences
Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field. The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. ''Telecommunication'' is often used in its plural form. Other examples of pre-modern long-distance communication included audio messages, such as coded drumbeat ...
