At 12:30 on December 12, 1901, in Newfoundland, eastern Canada, Marconi obtained three light morse strokes, signaling “s” from an antenna hanging from a kite. This is the first message to be transmitted across the Atlantic, from a radio station in Poldhu in Cornwall, England.
Italian inventor, Guglielmo Marconi, the director of this utopian experiment, went down in history as the “father of radio technology”. All modern telecommunications equipment, including radios, televisions, mobile phones and satellites all share this wireless communication team.
This year, the 118 th anniversary of the first transatlantic radio signal will be marked by the opening of a Marconi memorial museum and his achievements.
Dawn of the radio
On December 11, 1901, the first attempt to communicate across the Atlantic from Poldhu was done, but failed. Marconi, who is in Newfoundland, via an underwater telegraph cable, sent a message back to England, asking Poldhu signalers to send information to Canada. He received a weak signal, but the wind was so strong that the aerial aerial balloon was blown away.
The next few days, Marconi continued to experiment with a more firmly mounted antenna. This time, the signal from Cornwall was heard by both Marconi and George Stephen Kemp, his assistant. “My biggest concern is whether radio waves can be blocked by the earth’s curve. And then, I was convinced that it was impossible. At 12:30, I received the first reply :”… dot … dot … dot. “Marconi recounted.
At a time when the radio and television broadcast across the Atlantic became normal, Marconi’s success seemed to be unnoticed by anyone. But it is a scientific turning point that has changed the way communication is global. Marconi has proved what scientists now suspect – that a signal from thousands of kilometers away can be obtained. At that time, it was thought that radio communication over long distances was never possible, because electromagnetic waves, which only travel in a straight line, would be reflected into the universe or absorbed by the curved surface.
