The first transmission received on the continent of North America by Marconi was at Signal Hill, St. John's, Newfoundland and Labrador in 1901; Glace Bay, Nova Scotia was the site of the first such two-way transmission, in 1902. [2] One of the station's most notable roles occurred with the sinking of the RMS Titanic in April 1912.
A list of early wireless telegraphy radio stations of the Marconi Wireless Telegraph Co. Guglielmo Marconi developed the first practical radio transmitters and receivers between 1895 and 1901. His company, the Marconi Wireless Telegraph Co, started in 1897, dominated the early radio industry.
Guglielmo Giovanni Maria Marconi [11] [12] was born in Palazzo Marescalchi in Bologna on 25 April 1874, the second son of Giuseppe Marconi (an Italian aristocratic landowner from Porretta Terme who lived in the countryside of Pontecchio) and his Irish wife Annie Jameson (daughter of Andrew Jameson of Daphne Castle in County Wexford, sister of Scottish naturalist James Sligo Jameson, and ...
An iron and mercury variation on this device was used by Marconi for the first transatlantic radio message. An earlier form was invented by Jagdish Chandra Bose in 1899. [ 13 ] The device consisted of a small metallic cup containing a pool of mercury covered by a very thin insulating film of oil ; above the surface of the oil, a small iron disc ...

Marconi's experiments demonstrated the feasibility of a wireless telegraphy network across a desert terrain lacking in infrastructure, as was the case in places such as Libya. During the following months the WT detachment would set up a network that was controlled from a 1.5 kW spark transmitter on the quayside of the Turkish fort at Tripoli.
The German inventor and physicist Karl F. Braun demonstrated beamforming for the first time in 1905. Braun created a phased array by positioning three antennas to reinforce radiation in one direction and diminish radiation in other directions. [1] Guglielmo Marconi experimented with directional antennas in 1906. [2]
