Articles by Heinrich Rudolph Hertz died prematurely in 1894, he takes the field in the idea of \u200b\u200bbeing able to transmit and receive waves 'Hertz' long-distance, starting with his studies and experiments to create new and modify existing equipment. "It was my intention to follow in the production of electric oscillations via a completely opposite from that of scientists who were forced to demonstrations in which they were intent to make the character as far as possible equal to that of light waves." At the end of August 1895 Marconi transmits at a distance of 2400 meters of the Morse letter 'S', showing the exact analytical predictions of James Clerk Maxwell (1831-1879 philosopher, mathematical and physical).
