In earlier times, telecommunications involved the use of visual signals, such
as beacons, smoke signals, semaphore telegraphs, signal flags, and
optical heliographs, or audio messages such as coded drumbeats, lung-blown
horns, and loud whistles.
In modern times, telecommunications involves the
use of electrical devices such as the telegraph, telephone, and teleprinter, as
well as the use of radio, microwave transmission towers, fiber optics,orbiting
satellites and the Internet, which is a vast world-wide computer network.
A revolution in wireless telecommunications began in the first decade of 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 (telegraph), Alexander Graham
Bell(telephone), Edwin Armstrong.
