The History of Telecommunication
Transcript of The History of Telecommunication
Telecommunication The use and study of telecommunication began in 1834 when Carl F.Gauss and Ernst H. Weber built the first electromagnetic telegraph. This innovation was the first step to discovering how to make electrical signals travel from one device to another! In 1844 Samuel F. B. Morse demonstrates the Baltimore, Maryland, and Washington D.C. telegraph line. Phillip Reis develops the "telephon" which was the first instrument to ever be capable of transmitting the spoken words of a person's voice in 1860. It's very easy to recognize the closeness between this invention and the telephone. James C. Maxwell actually predicts electromagnetic radiation in 1864, which would later be used to further the use and study of telecommunication. By the year 1851 there were 51 telegraph companies in operation. There was actually an act that same year, 1851 that permitted telegraph companies to form legally. This means all 51 of these new businesses were the first on the market! In the year 1866 the first successful transatlantic telegraph line was installed. Prior to this, sending notifications and messages between the US and Europe took about 11 days! You can imagine how useful this type of communication was later during the world wars. The first Atlantic cable, promoted by Cyrus Field, was laid on July 27, 1867. Cyrus was known as the father of the Atlantic cable and the transatlantic cable. He began knowing nothing about the mechanics of telecommunication but completely understood the commercial power of connecting the US and Europe. Thomas Edison made the next great discovery along the road to reaching today's standards. Edison invented multiplex telegraphy in the year 1870, which would later help another man invent the telephone in the same decade. The Beginning of the Telephone Alexander Graham Bell supports, finalizes, and proves his theory of the telephone through experiments in 1875 on June 2. Alexander Graham Bell invents the telephone in the year 1876. Elisha Gray files a patent application 3 hours after Bell. In the next 11 years over 600 patent suits were filed. Settled in Bell's favor. Bell offers his patent to Western Union for $100,000. On March 7, 1876, the first telephone patent, No. 174,465, was issued to Alexander Graham Bell for his newest invention. A few days later on March 10, 1876, the first complete sentence of speech was transmitted over the telephone in Boston. On June 25, 1876, Bell exhibited the telephone to the judges from the Centennial Exposi-tion, Philadelphia. Bell successfully conducted the first two-way talk over the telephone between Boston and Com-bridgeport, Mass., a distance of 2 miles on October 9, 1876! In 1877 the Bell Telephone Company was created with Bell as "electrician" and Edison as "superintendent." In 1884 the first long distance telephone service, between Boston and New York City, which is 235 miles. The opening of a 950 mile telephone service occurred in 1892 with a line going from New York to Chicago! The longest calls in history open to the public! In 1900 John J. Carty , chef engineer of NY Tel (later AT&T), installs loading coils, invented by Micheal Pupin, to extend range and utilize open wire transposition to reduce cross talk. In 1904, John Ambrose Flemming invented the two element "Flemming Valve". The worlds first transatlantic commercial wireless services is established by Marconi with stations at Clifden, Ireland and Glace Bay, Nova Scotia in 1907 In 1911 a 2,100 mile call was made from New York to Denver by an overhead line. In 1914 the last pole of the transcontinental telephone line is placed in Wendover Utah. Then in 1915 the first transcontinental telephone line was opened from San Francisco to New York, 3600 miles. The first radiotelephone service was opened to the public in 1920! In 1925 the monophone was introduced to the public, the first hand set telephone of modern type. In 1927, Philo Farnsworth introduces the invention of the television by projecting the image of a dollar sign! The first round-world telephone conversation was held in the year 1935! In 1943 the first equipment for the dialing of called telephone numbers in distant cities becomes in service! In 1949"AT&T introduces the famous black rotary Model 500 telephone". On October 4, 1957, the first satellite was launched by the Russians. This was Sputnik. In 1974, the first domestic satellite was launched and began its operation. In 1981 the first cellular mobile telephone service is offered, in Saudi Arabia and Scandinavia. In 1992 the world wide web is born, and the man mainly responsible is Tim Berners-Lee. That same year, the first audio and video multicasts were broadcast over the internet. Today we have so many luxuries with cell phones, computers, the internet, radio, and other methods of telecommunications. Since the mid 1990's, telecommunication has been molded to look as it does in today, 2012. A popular question though, is: Where will it go from here? I think the future of telecommunication will involve not just live video, but things such as holograms and 3-D displays as well as updating all of our technology now to make it as fast as possible. All of this is a feasible goal for the near future, so only time will tell when these inventions will be aroused.
