Guglielmo Marconi in the context of "Ferdinand Braun"

Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electrical or electronic means, typically through cables, radio waves, or other communication technologies. These means of transmission may be divided into communication channels for multiplexing, allowing for a single medium to transmit several concurrent communication sessions. Long-distance technologies invented during the 20th and 21st centuries generally use electric power, and include the electrical telegraph, telephone, television, and radio.

Early telecommunication networks used metal wires as the medium for transmitting signals. These networks were used for telegraphy and telephony for many decades. In the first decade of the 20th century, a revolution in wireless communication began with breakthroughs including those made in radio communications by Guglielmo Marconi, who won the 1909 Nobel Prize in Physics. Other early pioneers in electrical and electronic telecommunications include co-inventors of the telegraph Charles Wheatstone and Samuel Morse, numerous inventors and developers of the telephone including Antonio Meucci, Philipp Reis, Elisha Gray and Alexander Graham Bell, inventors of radio Edwin Armstrong and Lee de Forest, as well as inventors of television like Vladimir K. Zworykin, John Logie Baird and Philo Farnsworth.

Bermuda rig, Bermudian rig, or Marconi rig is a type of sailing rig that uses a triangular sail set abaft (behind) the mast. It is the typical configuration for most modern sailboats. Whilst commonly seen in sloop-rigged vessels, Bermuda rig is used in a range of configurations, for instance, a cutter or a schooner (where it may be used in conjunction with gaff rigged sails on other masts), and several other types.

Bermuda rig takes its name from Bermuda, where it was developed in the 17th century. The term Marconi, a reference to the inventor of the radio, Guglielmo Marconi, became associated with this configuration in the early 20th century, because the wires that stabilize the mast of a Bermuda rig reminded observers of the wires on early radio masts.

Wireless telegraphy or radiotelegraphy is the transmission of text messages by radio waves, analogous to electrical telegraphy using cables. Before about 1910, the term wireless telegraphy was also used for other experimental technologies for transmitting telegraph signals without wires. In radiotelegraphy, information is transmitted by pulses of radio waves of two different lengths called "dots" and "dashes", which spell out text messages, usually in Morse code. In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code.

Radiotelegraphy was the first means of radio communication. The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. 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 allowed sound (audio) to be transmitted by radio. Beginning about 1908, powerful transoceanic radiotelegraphy stations transmitted commercial telegram traffic between countries at rates up to 200 words per minute.

The Marconi Company was a British telecommunications and engineering company founded by Italian inventor Guglielmo Marconi in 1897 which was a pioneer of wireless long distance communication and mass media broadcasting, eventually becoming one of the UK's most successful manufacturing companies.

Its roots were in the Wireless Telegraph & Signal Company, which underwent several changes in name after mergers and acquisitions. In 1999, its defence equipment manufacturing division, Marconi Electronic Systems, merged with British Aerospace (BAe) to form BAE Systems. In 2006, financial difficulties led to the collapse of the remaining company, with the bulk of the business acquired by the Swedish telecommunications company Ericsson.

Vatican Radio (Italian: Radio Vaticana; Latin: Statio Radiophonica Vaticana) is the official broadcasting service of Vatican City.

Established in 1931 by Guglielmo Marconi, today its programs are offered in 47 languages, and are sent out on short wave, DRM, medium wave, FM, satellite and the Internet. Since its inception, Vatican Radio has been maintained by the Jesuit Order. Vatican Radio preserved its independence during the rise of Fascist Italy and Nazi Germany.

Fascist architecture encompasses various stylistic trends in architecture developed by architects of fascist states, primarily in the early 20th century. Fascist architectural styles gained popularity in the late 1920s with the rise of modernism along with the ultranationalism associated with fascist governments in western Europe. Fascist styles often resemble that of ancient Rome, but can extend to modern aesthetics as well. Fascist-era buildings are frequently constructed with particular concern given to symmetry, simplicity, and monumental size, especially for public buildings.

Benito Mussolini utilised several styles of architecture, incorporating classical elements into modern Rationalist architecture to convey a sense of continuity with ancient Rome.
