Telecommunications

The first milestone in the discovery of modern telecommunications was given in the 1800s, with the idea, that electricity can be used to transmit a signal.

The telegraph was the first media who provides an opportunity to send messages worldwide, faster than any other media in the mid-1800s. On 27 July 1866, the first transatlantic telegraph cable was runned, so the opportunity could be used. In 1876 a new form of telecommunication was born. The Scottish inventor Alexander Graham Bell created a prototype telephone. The modern telecommunication gets faster, sound messages can be transmitted now. Telegraphs and telephones used the technology to create modulated electrical impulses, send them by wire, receive and decode them, so the human could understand it.

The next step was to enable it to send messages wireless. In 1895 the Italian inventor Guglielmo Marconi showed, that messages can be cast broadly (broadcast) through space, by sending a message over 3 km to a device that wasn’t linked by wire with the sending device.  The radio was born. In 1884 the German inventor Paul Nipkow succeeded to transmit an image, by using his mechanical system “The rotating Nipkow disk”, but the “electronic tube system” established itself as a better system.  The television was born.

In 1940, George Stibitz was able to transmit problems to his Complex Number Calculator and receive the computed results back, by teletype. So researchers created methods, to connect computers to a network. -> The internet was invented.

Today, there aren’t really new inventions. The former inventions are improved and the wireless communication gets more and more important. In future, they will do what they are still doing: improving the state of the art and getting the internet even more important.
