THE PATH TO 5G series - Episode #1 - The Ground Work

In 1894, Guglielmo Marconi started engineering a wireless telegraph system which used radio were known about since proof of their existence in 1888 by Heinrich Hertz, but discounted as a communication format since they seemed, at the time, to be short range.

Marconi began experimenting with radio waves as a student at the Livorno Technical Institute. Incorporating the earlier scientific work of Henry R. Hertz and Oliver Lodge in electromagnetic radiation, he was able to develop a basic system of wireless telegraphy. Though not a scientist, Marconi recognized the value of wireless technology and was adept in putting the right people together to invest in it. In 1897 he received his first patent in England.

His initial transmission only traveled a mere mile and a half but on December 12, 1901, Marconi sent and received the first wireless message across the Atlantic Ocean, from Cornwall, England, to a military base in Newfoundland. His experiment was significant, as it disproved the dominant belief of the Earth's curvature affecting transmission.

In 1902, Marconi worked on experiments that stretched the distance that wireless communication could travel, until he was finally able to establish transatlantic service from Glace Bay in Nova Scotia, Canada, to Clifden, Ireland. For his work with wireless communication, Marconi was awarded the Nobel Prize in Physics for it in 1909.

( Interesting fact ) Not long after his award Marconi's wireless system was used by the crew of the RMS Titanic to call for assistance. This technology may have been the most important factor in the survival of the 706 people who lived through this horrific event known as the Titanic.

Marconi held several positions in the Italian Army and Navy during World War 1, starting the war as a lieutenant in 1914 and later finishing as a naval commander. He was sent on diplomatic missions to the United States and France. After the war, Marconi began experimenting with basic short wave radio technology. On his yacht, he conducted experiments in the 1920s proving the efficacy of the "beam system" for long-distance communication. (The next step would lead to microwave transmission.) By 1926, Marconi's "beam system" had been adopted by the British government as a design for international communication.

In addition to his groundbreaking research in wireless communication, Marconi was instrumental in establishing the British Broadcasting Company which was formed in 1922. He was also involved in the development of radar. Marconi continued to experiment with radio technology in his native Italy until his death, on July 20, 1937, in Rome, from heart failure.

In 1943, the U.S. Supreme Court ruled that some of his patents’ source of discovery was questionable and as a result restored some prior patents to other scientists, including Oliver Lodge and Nikola Tesla, predated some of his findings. The Court’s decision had no effect on Marconi’s claim that he was the first to produce radio transmission, he just couldn’t claim credit for the groundwork.
