The concept of telecommunications encompasses all forms of remote communication. The word includes the Greek prefix tele, which means “distance” or “far.” Therefore, telecommunication is a technique that consists of transmitting a message from one point to another, normally with the additional characteristic of being bidirectional. Telephone, radio, television and computer data transmission are part of the telecommunications sector.
In the field of telecommunications, it is important to know the importance of the variety of physical materials 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 opt for the most suitable material. Specifically, experts in this field must carefully analyze what the costs are, the security, the capacity it has, the errors it can cause or also how easy it is to use.
The English physicist James Clerk Maxwell was in charge of laying the foundations for the development of telecommunications, by introducing the concept of electromagnetic wave 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 using electric discharges, something that Heinrich Hertz verified in 1887. The history of telecommunications began to develop in the first half of the 19th century, with the electric telegraph (which allowed the sending of messages with letters and numbers). Later came the telephone, which added the possibility of voice communication. With radio waves, wireless communication has come to complete a true revolution in the habits of mankind. Of course, technological innovations in the field of telecommunications have 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. In the educational and training field, it is important to note that, at the university level, there is a Degree in Telecommunication Technology Engineering in Spain. The degree is, in turn, made up of two areas (Sound and Image and Telecommunication Systems) and allows students who take it to access the position of Technical Telecommunications Engineer.
Such is the importance of telecommunications technologies in today’s society that this profession has become one of the most promising for the future. And it is that the specialists in the matter will be able to find work both in network operators and in manufacturers of telecommunications equipment, going through radio broadcasting companies and even in television operators. And all this without forgetting that another of the most sought-after professional opportunities is in the area of configuration, installation and maintenance of mobile and optical communications networks. Today, telecommunications is an industrial sector that moves millions of dollars a year around the world.
