Plural form of telecommunication.
Telecommunication is communication at a distance by technological means, particularly through electrical signals or electromagnetic waves. Early telecommunication technologies included visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, and optical heliographs. Other examples of pre-modern telecommunications include audio messages such as coded drumbeats, lung-blown horns, and loud whistles. Electrical and electromagnetic telecommunication technologies include telegraph, telephone, and teleprinter, networks, radio, microwave transmission, fiber optics, communications satellites and the Internet. A revolution in wireless telecommunications began in the 1900s with pioneering developments in radio communications by Nikola Tesla and Guglielmo Marconi. Marconi won the Nobel Prize in Physics in 1909 for his efforts. Other highly notable pioneering inventors and developers in the field of electrical and electronic telecommunications include Charles Wheatstone and Samuel Morse, Alexander Graham Bell, Edwin Armstrong, and Lee de Forest, as well as John Logie Baird and Philo Farnsworth. The world's effective capacity to exchange information through two-way telecommunication networks grew from 281 petabytes of information in 1986, to 471 petabytes in 1993, to 2.2 exabytes in 2000, and to 65 exabytes in 2007. This is the informational equivalent of two newspaper pages per person per day in 1986, and six entire newspapers per person per day by 2007. Given this growth, telecommunications play an increasingly important role in the world economy and the global telecommunications industry was about a $4.7 trillion sector in 2012. The service revenue of the global telecommunications industry was estimated to be $1.5 trillion in 2010, corresponding to 2.4% of the world’s gross domestic product.
