The idea of telecommunication is linked to distance communication.
The concept of telecommunications encompasses all forms of distance communication . The word includes the Greek prefix tele , meaning "distance" or "far."
Therefore, telecommunication is a technique that consists of the transmission of a message from one point to another , usually with the additional characteristic of being bidirectional . Telephony , radio , television , and data transmission through computers are part of the telecommunications sector.
James Clerk Maxwell and telecommunications
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 performance, and in this sense this means that it is necessary to study a series of guidelines and criteria to choose the most appropriate material. Specifically, experts in this area have to thoroughly analyze the costs, the security, the capacity it has, the errors it may bring, or also the ease of use 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 waves to describe the interaction between electricity and magnetism through mathematics. In this way, Maxwell announced that it was possible to propagate waves through free space by using electric discharges , something that Heinrich Hertz verified in 1887 .
Telephony is part of the telecommunications sector.
Historical tour
The history of telecommunications began to develop in the first half of the 19th century, with the electric telegraph (which allowed messages to be sent with letters and numbers). Later the telephone appeared, which added the possibility of communicating using voice. With radio waves , wireless communication came to complete a true revolution in the habits of humanity.
Of course, technological innovations in the field of telecommunications never stopped. The modem made it possible to transmit data between computers and other devices, which was the starting point for the development of the Internet and other computer networks.
Telecommunications Technology Engineering
In the educational and training field, it is important to emphasize the fact that, at the university level, there is a Degree in Telecommunications Technology Engineering in Spain. This degree is, in turn, made up of two areas (Sound and Image, and Telecommunications Systems) and allows students who complete it to obtain a job as a Telecommunications Technical Engineer.
Such is the importance of telecommunications technologies in today's society that this profession has become one of those with the most future prospects. And experts in the field will be able to find a job both in network operators and in telecommunications equipment manufacturers, through radio broadcasting companies and even television operators. And all this without forgetting that another of the most in-demand 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 a year around the world.
