Wireless telegraphy or radiotelegraphy is the transmission of text messages by radio waves, analogous to electrical telegraphy using cables. [ 1 ] [ 2 ] Before about 1910, the term wireless telegraphy was also used for other experimental technologies for transmitting telegraph signals without wires.
The signals broadcast by the aeroplane carrying the Rouzet system were the only ones received unbroken. The military demanded another test, but war was on its way, and the test was not carried out. As a result, the French air squadrons had no wireless telegraph. However, the Rouzet system was used by the allied forces.
Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to transmit wireless data for telecommunications or computer networking. "Free space" means the light beams travel through the open air or outer space.
The Wardenclyffe Power Plant prototype, intended by Nikola Tesla to be a "World Wireless" telecommunications facility.. The World Wireless System was a turn of the 20th century proposed telecommunications and electrical power delivery system designed by inventor Nikola Tesla based on his theories of using Earth and its atmosphere as electrical conductors.
Radio resource management (RRM) is the system level management of co-channel interference, radio resources, and other radio transmission characteristics in wireless communication systems, for example cellular networks, wireless local area networks, wireless sensor systems, and radio broadcasting networks.
The following outline is provided as an overview of and topical guide to telecommunication: . Telecommunication – the transmission of signals over a distance for the purpose of communication.
Telecommunications engineer working to maintain London's phone service during World War 2, in 1942. Telecommunications engineering is a subfield of electronics engineering which seeks to design and devise systems of communication at a distance.
In 1908, students at Columbia University formed the Wireless Telegraph Club of Columbia University, now the Columbia University Amateur Radio Club. This is the earliest recorded formation of an amateur radio club, collegiate or otherwise. [7] In 1910, the Amateurs of Australia formed, now the Wireless Institute of Australia.
