Historia de las telecomunicaciones

From radio systems, patent 7777 and communications in the times of the Great War to the electronic revolution of the 19th century, television or mobile communication. What were the first forms of telecommunication? How did the French Revolution influence the development of information technologies? What was the impact of electricity on telegraphy systems? Did you know that a painter, Samuel Morse, motivated by the slow arrival of news after the death of his wife, was the inventor of a telegraphy system and the immortal code that would bear his last name? What was the epic of submarine telegraphy? How was the magic of voice transmission achieved?... The history of telecommunications is the exciting story of how technology gave new tools to human beings so that, without having to travel, they could reach greater distances and interact with others similar to those he had never seen before; It is the story of the creation of instruments that allowed us to achieve the dream of being in contact with other environments without having left our own. And, at the same time, feeling the limitations of space and time vanish. In this work, José Antonio Martín Pereda masterfully immerses us in the fascinating world of telecommunications, linking technological development, its characters and great achievements, with the progress of societies until reaching the present day, in what continues to be be the prologue of what will come later.
