Contributions and Achievements

Marconi was convinced that communication among people was possible via wireless radio signaling. He started conducting experiment in 1895 at his fathers home in Pontecchio, where he was soon able to send signals over one and a half miles. During this period, he also carried out simple experiments with reflectors around the aerial to concentrate the radiated electrical energy into a beam instead of spreading it in all directions.In 1896 Marconi traveled to England in order to get a patent for his apparatus. Later that year he was granted the worlds first patent for a system of wireless telegraphy. After successfully demonstrating the systems ability to transmit radio signals in London, on Salisbury Plain and across the Bristol Channel, he established the Wireless Telegraph & Signal Company Limited in July 1897. This company was renamed as Marconis Wireless Telegraph Company Limited in 1990.

In 1899 he established a wireless link between Britain and France across the English Channel. Further he established permanent wireless stations at The Needles, Isle of Wight, Bournemouth, and later at the Haven Hotel in Poole, Dorset. The following year he received his patent for tuned or systonic telegraphy.During December 1901 Marconi proved that wireless signals were unaffected by the curvature of the earth. He transmitted the first wireless signals across the Atlantic between Poldhu, Cornwall and St, Johns, New Foundland, a distance of 2100 miles.The next year he demonstrated daylight effect relative to wireless communication and also he patented his magnetic detector, which was the standard wireless receiver for many years. In December he successfully transmitted the first complete message to Poldhu from stations at Glace Bay, Nova Scotia and Cape Cod Massachusetts.In 1905 and 1912 Marconi patented his horizontal directional aerial and patented a timed spark system for generating continuous waves respectively.
