A French ship-to-shore radio station in 1904. The invention of radio communication was preceded by many decades of establishing theoretical underpinnings, discovery and experimental investigation of radio waves, and engineering and technical developments related to their transmission and detection. These developments allowed Guglielmo Marconi ...
Guglielmo Giovanni Maria Marconi, 1st Marquis of Marconi GCVO FRSA (Italian: [ɡuʎˈʎɛlmo marˈkoːni]; 25 April 1874 – 20 July 1937) was an Italian [1][2][3][4] inventor, electrical engineer, physicist, and politician, known for his creation of a practical radio wave –based wireless telegraph system. [5] This led to Marconi being ...
A regular transatlantic radio-telegraph service was finally begun on 17 October 1907 [33] [34] 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. [35]
1898: Marconi opened the first radio factory, on Hall Street, Chelmsford, England, employing around 50 people. 1899: Bose announced his invention of the "iron-mercury-iron coherer with telephone detector" in a paper presented at Royal Society, London. 1899: Tesla experiments with wireless power in Colorado Springs.
Radio is the technology of communicating using radio waves. [1][2][3] Radio waves are electromagnetic waves of frequency between 3 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates oscillating electrical energy, often characterized as a wave.
The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. [5] It continued to be the only type of radio transmission during the first few decades of radio, called the "wireless telegraphy era" up until World War I , when the development of amplitude modulation (AM) radiotelephony ...
History of broadcasting. The Marconi Company was formed in England in 1910. The photo shows a typical early scene, from 1906, with Marconi employee Donald Manson at right. The British Broadcasting Corporation's landmark and iconic London headquarters, Broadcasting House, opened in 1932. At right is the 2005 eastern extension, the John Peel wing ...
The monopole antenna was invented in 1895 and patented in 1896 [7] by radio pioneer Guglielmo Marconi during his historic first experiments in radio communication. He began by using dipole antennas invented by Heinrich Hertz consisting of two identical horizontal wires ending in metal plates.
