First Wireless communication across the Atlantic

At the turn of the 20th century, Guglielmo Marconimi, an Italian inventor and electric engineer, began investigating a means to signal across the Atlantic to compete with the transatlantic telegraph cables. Marconi established a wireless transmitting station at Marconi House, Rosslare Strand, County Wexford, in 1901 to act as a link between Poldhu in Cornwall, England, and Clifden in Connemara, County Galway, Ireland. He soon made the announcement that the message was received at Signal Hill in St. John's, Newfoundland (now part of Canada), on 12 December 1901, using a 500-foot (150 m) kite-supported antenna for reception—signals transmitted by the company's new high-power station at Poldhu, Cornwall. The distance between the two points was about 2,200 miles (3,500 km).
