World Radio Day

Marconi began to build high-powered stations on both sides of the Atlantic to communicate with ships at sea. In 1904, he established a commercial service to transmit nightly news summaries to subscribing ships, which could incorporate them into their on-board newspapers. A regular transatlantic radio-telegraph service was finally begun on 17 October 1907 between Clifden, Ireland, and Glace Bay, but even after this the company struggled for many years to provide reliable communication to others. Marconi's apparatus is also credited with saving the 700 people who survived the tragic Titanic disaster .

Radiotelegraphy equipment was first installed on the Eiffel Tower in paris. But his equipment did not convey comprehensible messages. Photograph of Guglielmo Marconi radio equipment, c.1902.

12 December: Marconi makes the first transatlantic wireless transmission , using Morse code , between Poldhu in Cornwall (U.K.) and St. John's Newfoundland.

  Marconi obtains a patent for a process enabling a operator to select a wavelengh . (The first receivers picked up all frequencies at the same time.) Febryary: the first commercial wireless station is set up, on the island of Borkum (Germany).

 Eugène Ducretet (France) experiments with wireless telegraphy ; Guglielmo   Marconi founds the Wireless Telegraph and Signal Company Ltd ., in London. Karl Ferdinand Braun (Germany) invents a device which completes '' the tuned circuit '', matching the wavelengt of transmitter and receiver, a procedure discovered by Sir Oliver Lodge (U.K.).

 2 June : In England, Guglielmo Marconi files a patent for a system of wireless communication , and later transmits and receives Morse code signals over a 3 km distance.
