The Marconi Wireless Corporation operated Ship to Shore, Spark gap, VLF, and Trans-Oceanic wireless telegraph stations. Since the 1890s, numerous pioneering radio stations were located in Canada, Ireland, Newfoundland, the United States, the United Kingdom and a number of other locations around the world.
Ship based stations managed by Marconi Company provided communications between ships and coastal stations for navigation and to pass commercial messages between passenger ship clients and coastal stations.
Coastal Stations provided navigation and weather service and relayed communications from ships to other coastal stations and through telegraph systems.
Trans-Oceanic Wireless Telegraph stations were large facilities with huge antenna structures capable of continuously sending automatic Morse code messages across vast distances. Communications across the Atlantic and Pacific Oceans were of this type.
In 1906, the Marconi Company constructed an experimental station at Queenscliff, Victoria, successfully communicating between the Australian continent and Devonport, Tasmania. This station operated on a temporary basis; subsequent Australian wireless efforts would be undertaken by Amalgamated Wireless Australasia, established in 1913 under ownership of Marconi, its commercial arch-rival Telefunken and Australian local business interests.
The Marconi Company has owned or operated Canadian coastal radio stations since 1902, either as trans-Atlantic radiotelegraph links or as marine radio stations. While eastern Canada's ship-to-shore coastal stations were government-owned after 1915, the Marconi Company had been paid to continue to operate the facilities. Canada's west coast had been served by government-operated stations since 1907; many stations in the Canadian Arctic were military operations.
