History of Telecommunication

Introduction

Since ancient times, long-distance communication has become a need and a necessity. Thus, one sees bright lights and torches in Greece, drums and trumpets on the battlefield and drums in the bush, the smoke among the Indians, the horn on the outskirts of castles or singing in Tyrol.

Telecommunication is the transmission of information over significant distances to communicate. In earlier times, telecommunications involved the use of visual signals. For example, in the modern age of electricity and electronics, telecommunications now also includes the use of electrical devices such as telegraphs, telephones, and teleprinters, the use of radio and microwave communications, as well as fiber optics and their associated electronics, plus the use of the orbiting satellites and the Internet.

Discussion and analysis

History of telecommunication

The first telecommunications processes were smoke signals used by the Native Americans of North and South, and the drums, which used by the peoples of Africa, New Guinea and South America. These signals allow the transmission of information can be complex. The Yagan, for example, used smoke signals to indicate beached whales, so that more can take the meat from the carcass before it decomposes.

In the middle Ages, towers placed on the tops allowed to transmit orders and strategic information, but the information limited to the equivalent of a bit modern as "the enemy is in sight." One example is the transmission of Plymouth to London by the arrival of the "invincible armada". In 1791, the French engineer Claude Chappe made ??the first optical telegraph system semaphore between Paris and Lille. They asked for skilled operators and expensive towers spaced ten to thirty kilometers, but allowed to transmit messages within hours all over France (Brown, 2004).

Official definition of "Telecommunications"

The term telecommunications formally defined, for the first time, at the international conference in Madrid in 1932. In fact, to date, there were two different legal entities, the International Telegraph, first (the oldest: it created in 1865 in Paris) and the International telegraph (the first meeting) It held in Berlin in 1906). In 1932, these two conferences met again, but together in Madrid. After discussions and exchanges of view, we finally heard the name International Telecommunication Union (ITU). As the exact term telecommunications defined at the Madrid Conference as follows:

"Any telegraph or telephone communication of signs, signals, writing and sounds of any nature by wire or other radio systems or processes or visual electric signal (semaphore)".

Prehistory Telecommunications

The history of modern telecommunications is relatively recent. It begins, in fact, there's a century and a half, exactly with the invention of the electric telegraph by Samuel Morse in 1837. The invention of the telephone by Alexander Graham Bell is even more recent, in 1876, that is to say a little more than a century. However, the origin of telecommunications is much older. Traditionally men have sought to overcome the barriers of time and space, and for this, they have tried to improve their communication and, more particularly, the transmission speed of information ...
