The history of telecommunication began with the use of smoke signals and drums in Africa, Asia, and the Americas. In the 1790s, the first fixed semaphore systems emerged in Europe . However, it was not until the 1830s that electrical telecommunication systems started to appear.
Human communication was initiated with the origin of speech approximately 100,000 BCE. [1] Symbols were developed about 30,000 years ago. The imperfection of speech allowed easier dissemination of ideas and eventually resulted in the creation of new forms of communication, improving both the range at which people could communicate and the longevity of the information.
Earth station at the satellite communication facility Raisting Earth Station in Raisting, Bavaria, Germany. Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies.
RCA Electronic Music is the first synthesizer prior to the creation of artificial electronic sounds. 1952 Reintroduction of regular television broadcasts in Germany after the Second World War. 20th Century Fox developed with "Cinemascope" the most successful wide-screen process to better compete with television. Only some 50 years later pulls ...
Electronic modulation was developed between 1832 and 1927 and was a crucial development in the history of telecommunications. Electronic multiplexing, which allowed for the transmission of multiple signals over a single channel, was first developed in 1853 using a technique called time-division multiplexing (TDM). [12]
During 1790–1795, at the height of the French Revolution, France needed a swift and reliable communication system to thwart the war efforts of its enemies. In 1790, the Chappe brothers set about devising a system of communication that would allow the central government to receive intelligence and to transmit orders in the shortest possible time.
A broadcasting antenna in Stuttgart. Broadcasting is the distribution of audio or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. [1]
This article details the history of electronics engineering. Chambers Twentieth Century Dictionary (1972) defines electronics as "The science and technology of the conduction of electricity in a vacuum, a gas, or a semiconductor, and devices based thereon".
