History of radio upon the idea of grounding his transmitter and receiver. With these improvements the system was capable of transmitting signals up to and over hills. Marconi's experimental apparatus proved to be the first engineering-complete, commercially successful radio transmission system. Marconi's apparatus is also credited with saving the 700 people who survived the tragic "Titanic" disaster. In 1896, Marconi was awarded British patent 12039, "Improvements in transmitting electrical impulses and signals and in apparatus there-for", the first patent ever issued for a Hertzian wave (radio wave) base wireless telegraphic system. In 1897, he established a radio station on the Isle of Wight,
Guglielmo Marconi longwave transmissions travel much farther at night than in the day. During the daytime, signals had been received up to only about , less than half of the distance claimed earlier at Newfoundland, where the transmissions had also taken place during the day. Because of this, Marconi had not fully confirmed the Newfoundland claims, although he did prove that radio signals could be sent for hundreds of kilometres, despite some scientists' belief that they were limited essentially to line-of-sight distances. On 17 December 1902, a transmission from the Marconi station in Glace Bay, Nova Scotia, Canada became the world's first
