The development of wireless communication that led to the Alexanderson alternatorNot much has changed in human nature in the last two centuries. When we want something, we want exactly what we want without deviation and we want to have it quickly. This is as evident in modern times as it was in the late 19th and early 20th centuries. It is difficult for modern man to imagine, but there was a time when messages and information had to be delivered by hand, on horseback or by vehicle. . This was a big problem in a world that was rapidly expanding and evolving and was filled with growing local and international unrest. The more the world began to expand, the more difficult it became to transmit messages and information, and the more innovative and unstable society became, the greater the need to transmit information became. The first major innovation in long-distance information transfer came in the use of the telegraph. The telegraph was a device that transmitted electrical impulses along a wire. This allowed a person at one end of the cable to transfer an electrical signal from one location to another. By varying the pulse of the electrical signal, the first rudimentary messages were sent by Samuel Soemmering in 1809. “He used 35 wires with gold electrodes immersed in water and at the receiving end at 2000 feet the message was read by the amount of gas caused from electrolysis.” [4] Basically, Soemmering created pulses of electricity at one end of his cables and 2000 feet away at the end of the cable, different concentrations of gas were emitted depending on the strength/duration of the pulse sent, an information relay on 2000 feet thanks to the use of electricity.A huge revolution in the field of electronic communication……medium of paper……as one of the first devices to produce continuous waves. To carry a human voice, Fessenden needed a pure sine wave on a single frequency. Spark gap technology was too noisy to allow this, but Alexanderson's alternator made this task possible by generating a pure continuous wave. On Christmas Eve 1906, Fessenden realized his dream and transmitted the first human voice along with the music of a violin to naval fleets across the Atlantic and to other receivers tuned to hear it. This innovation was revolutionary in the field of AM radio broadcasting. It also enabled long-distance wireless communication during the world wars of the early 20th century. It is safe to say that radio and the entire field of wireless communication would not be where they are today without the work of Fessenden and Alexanderson and the invention of the Alexanderson alternator..
