The concept of telecommunication encompasses all forms of communication from distance. The word includes the Greek prefix TV, what does it mean “distance” or “far”. Therefore, telecommunication is a technique which consists of the transmission of a message from one point to another, usually with the added feature of being bidirectional. The telephony, the radio, the TV and the transmission of data through computers they are part of the telecommunications sector.
Within the field of telecommunications, it is important to know the importance of the variety of physical material used in them. The success of the process depends on it, its quality and its benefits, and in this sense this leads to the need to study a series of guidelines and criteria to bet on the most appropriate material. Specifically, experts in this area have to proceed to carefully analyze what are the costs, the security, the capacity it has, the errors that it can bring with it or also the ease of use that it has.
The English Physicist James Clerk Maxwell was responsible for laying the foundations for the development of telecommunications, by introducing the concept of electromagnetic wave to describe through mathematics the interaction between electricity and magnetism. Thus, Maxwell announced that it was possible propagate waves through free space when using electric shock, something that checked Heinrich Hertz on 1887.
The history of telecommunications began to develop in the first half of the 19th century, with the electric telegraph (that allowed to send messages with letters and numbers). Later the telephone, which added the ability to communicate using voice. With the radio waves, wireless communication came to complete a true revolution in the habits of mankind.
Of course, technological innovations in the field of telecommunications never stopped. The modem enabled the transmission of data between computers and other devices, which was the starting point for the development of Internet and other computer networks.
In the field of education and training, it is important to emphasize the fact that, at the university level, there is a Degree in Telecommunications Technology Engineering in Spain. A degree is that, in turn, is made up of two areas (Sound and Image, and Telecommunication Systems) and that allows students who do it to get a job as a Telecommunication Technical Engineer.
Such is the importance of telecommunication technologies in today’s society that this profession has become one of those with the greatest prospects for the future. And it is that experts in the field will be able to find a job both in network operators and in telecommunications equipment manufacturers, through broadcasting companies and even in television operators. And all this without forgetting that another of the most popular professional opportunities is in the area of configuration, installation and maintenance of mobile and optical communication networks.
Today, telecommunications make up an industrial sector that moves millions of dollars per year around the world.
