Wireless: from Marconi's Black-box to the Audion

Wireless: From the black box of Marconi to Audiion Wireless, the initial development of the radiotelephone and the systematic explanation of that possible inventor. Sungook Hong has studied several early major inventions, including Hertz wave and optical element, ammeter, transatlantic signal, Marconi's secret box, Fleming's air blast key and double conversion system, and Rocky's synthetic transmitter did. Receiver, Edison effect, thermoelectric bulb and auditory and continuous wave.

Guglielmo Marconi (1874 - 1937) was an inventor of Italy and acquired the first patent of the radio telegraph system. In 1900, Marconi proved that radio waves are not affected by the shape of the Earth when transmitting a radio signal of 2,100 mile on the Atlantic Ocean. He continued his study of waves, which led to the principle of the beam system for long distance communication, the first microwave radio and radar. He has won many awards, including the Nobel Prize in Physics.

In 1894, Guglielmo Marconi began to develop a radio telephone system using radio waves and was known since Heinrich Hertz proved its existence in 1888, but at that time it seemed a close range. This phenomenon is called communication format. . Marconi immediately developed a system capable of transmitting signals beyond the distance that everyone expected (the reason is that the signal reflected from the ionosphere, but it was unknown at that time). Guglielmo Marconi and Karl Ferdinand Braun won the Nobel Prize in Physics in 1909, thanks to its contribution to this form of radio telegraph.

More than 100 years ago, Guglielmo Marconi was a pioneer in remote radio communications. Before Marconi Wireless appeared, it was impossible for marine vessels to communicate with the coast. Prior to Marconi, physicists were experimenting with radio waves and were keenly interested in this phenomenon. However, no one thought of trying to solve the problem of wireless communication. Marconi experimented infinitely. When physicists try to learn more about the science behind electromagnetism, Marconi is busy trying to solve the problem. He tried various shapes, sizes and antenna arrangements until he could transmit a signal more than two miles. From there, he constantly tried various kinds of metals, various electrical configurations and different power levels until he could transmit throughout the Atlantic.
