History of radio a system for transmitting intelligence and wireless power using the earth as the medium. Others, such as Amos Dolbear, Sir Oliver Lodge, Reginald Fessenden, and Alexander Popov were involved in the development of components and theory involved with the transmission and reception of airborne electromagnetic waves for their own theoretical work or as a potential means of communication. Over several years starting in 1894 the Italian inventor Guglielmo Marconi built the first complete, commercially successful wireless telegraphy system based on airborne Hertzian waves (radio transmission). Marconi demonstrated the application of radio in military and marine communications and started a company
Italian cruiser Carlo Alberto the fleet review at Spithead on 16 August. On the return voyage Marconi conducted more long-range experiments with his site in Poldhu, Cornwall. The King then loaned "Carlo Alberto" to Marconi in September for more testing. She then ferried Marconi across the Atlantic to Glace Bay, Nova Scotia for further experiments transmitting radio messages across the ocean. After 15 December, when Marconi successfully transmitted messages from Glace Bay to Poldhu, "Carlo Alberto" was sent to Venezuelan waters during the Venezuelan crisis of 1902–03, when an international force of British, German, and Italian warships blockaded Venezuela over the country's refusal to
