Communication revolutionized Marconi’s idea of sending messages through electromagnetic waves without a wire mesh. And established the roots of radio broadcasting.
Story Behind Invention Of First wireless Communication
It was the era of sending messages from the telegraph machine invented by Samuel Morse. Morse’s script, developed in 1844 with the help of dot (.) And dash (-), revolutionized the world of communication. By the time Moses died in 1872, a total of 10,50,00 km of telegraph cables had been established between the world and other countries. Another 50,000 kilometers of cables were laid at the bottom of the oceans, with about 20,000 cities and villages around the world able to exchange messages based on Morse code, but that communication was only possible by wire. There was still time to find the telephone.
Italian researcher Guglielmo Marconi, meanwhile, was scouring for a seemingly impossible piece of research. This scientist wanted to exchange electromagnetic waves and messages without the help of a wire. He and his two companions camped in December 1901 in St. John’s, the capital of Newfoundland in the North Atlantic. Marconi, a 6-year-old, set up a wireless receiving service in a military hospital on the coast. Jenny’s antennae kite was hovering in the sky with the help of a separate balloon, but the stormy wind was holding back her success.
The weather was also so bad that they did not succeed in capturing the required wavelength. A few more days passed in the same way. Five days later, on Wednesday, December 11, I made my first attempt to catch Marco’s signal. He thought he heard something in the earphones but he couldn’t believe it because of the thunder in the sky. Unfortunately, the balloon’s string attached to the antenna broke and it was time to drop the experiment.
Thursday, December 12, 1901, was to be an important day in the history of communications, not only for Marconi’s research. The antennas of the wireless receiving centers were tied to a giant kite and hoisted about 200 feet above the ground. Even in constant embarrassment, he tried to listen intently by putting earphones on Marco’s ears. He was waiting for a message from 48 kilometers away from the other side of the North Atlantic Ocean. At 12:30 Marconi heard a slow but clear sound of 3 dots. According to Samuel Morse, the message of 3 dot showing S was sent to John Ambrose Fleming, the manager sitting in a power station at Cornwall, England. To confirm the message, Marconi’s app called his assistant George Camp and asked, ‘Can you hear anything, Mr camp?’ The answer was a resounding no, so Marconi was determined to do more research.
However, many researchers did not accept Marconi’s claim that the successful transmission of Bintari’s message was not a “neutral” witness to the incident. People were adamant that a communication link could not be established without a Morse code message flowing over the wire. Marconi’s success in sending wireless messages across the Atlantic was completely denied by the American scientist Thomas Addis.
But the newspapers, which called Marconi’s successful experiment a “revolutionary achievement,” proved to be superior to enough researchers.
The newspapers’ faith in Marconi was not entirely unfounded. Marco did a small rehearsal of the St. John’s Experiment 15 years ago. The experiments of the German scientist Hentick Haz, who proved that electromagnetic waves could be transmitted into the atmosphere, became the basis for Marconi’s research. Is. In 1885, in Italy, 4 km from his farm. Marconi successfully sent a wireless message to a distant farm. A few years later, he succeeded in transmitting wireless messages across a 60-kilometer English channel, and by the end of the eighteenth century, sea-going ships began to communicate with land using Marconi’s equipment. Is. In 1899, wireless messaging was first used to rescue a shipwreck.
(Years later, in 1912, the wireless operator of the Titanic, which sank in a collision with an iceberg in the North Atlantic, was to send a final message of help to the ship Carpe Thea. The department rejected Marconi’s offer to use ‘wireless’, as Samuel Morse’s telegraphic communication system, which was considered reliable at the time, was more favorable to the government.
Marconi’s dream of transmitting the message over long distances with the help of electromagnetic waves came true, but he had to provide some concrete proof to silence the critics. In 1902, Marconi sailed from England to New York on a Philadelphia steamer to prove the evidence. An aerial was built along the steamer’s well pillar. Any sign of the Morse code coming through the magnetic waves instead of the wire was to be recorded by Ariel using a special printer. As the steamer moved forward, regular messages kept coming from Polu on the coast of England, about 2,500 miles [2,500 km] away. Even after covering a distance of about 3,200 km, the steamer clearly marked ‘S’. Wireless broadcasts were sealed with the signing of the Philadelphia canon on a message that had been recorded so far.
The discovery of wireless messaging was intended to give Marconi the title of “Pioneer of Radio Broadcasting” in addition to the 1909 Nobel Prize. The invention of the wireless transmission for the purpose of communication was to go far beyond Marconi’s expectations and was to become the foundation for radio broadcasts, which began in 1909, in the true sense of the word. A two-minute silence was observed in honor of the researcher.
The date after the turning point
- The first wireless radio connection between England and Australia was made in 1918. The first F.M. (Frequency Modulation) Transmitted.
- 18 became the first radio telescope.
- Sony made the first transistor radio in the 19th century.
- The 14th communications satellite ‘Telstar’ was launched into space. The transmission of the wireless message became faster.
- The Voyager and Pioneer spacecraft, launched by the United States on its 14th visit to the Solar System, is still sending wireless messages to Earth from a distance of 10.5 billion kilometers. To this day, the boundaries of the direction of progress that Marconi opened for mankind by transmitting the first wireless message about 2,500 kilometers away have not come to an end.
