The furthest maritime broadband transmission (no satellite) is 19.4 nautical miles (35.92 km) and was achieved by Arnaud Disant and SEA-Tech (both Ireland) in Cork, Ireland, on 6 June 2018.
This record was set to raise awareness on alternative marine data-communication, crew welfare and the possibility to give a second life cycle to lighthouses across the world.
