Telecommunication is the transmission of information by various types of technologies over wire, radio, optical, or other electromagnetic systems. It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field.
The transmission media in telecommunication have evolved through numerous stages of technology, from beacons and other visual signals (such as smoke signals, semaphore telegraphs, signal flags, and optical heliographs), to electrical cable and electromagnetic radiation, including light. Such transmission paths are often divided into communication channels, which afford the advantages of multiplexing multiple concurrent communication sessions. Telecommunication is often used in its plural form.
Other examples of pre-modern long-distance communication included audio messages, such as coded drumbeats, lung-blown horns, and loud whistles. 20th- and 21st-century technologies for long-distance communication usually involve electrical and electromagnetic technologies, such as telegraph, telephone, television and teleprinter, networks, radio, microwave transmission, optical fiber, and communications satellites.
A revolution in wireless communication began in the first decade of the 20th century with the pioneering developments in radio communications by Guglielmo Marconi, who won the Nobel Prize in Physics in 1909, and other notable pioneering inventors and developers in the field of electrical and electronic telecommunications. These included Charles Wheatstone and Samuel Morse (inventors of the telegraph), Antonio Meucci and Alexander Graham Bell (some of the inventors and developers of the telephone, see Invention of the telephone), Edwin Armstrong and Lee de Forest (inventors of radio), as well as Vladimir K. Zworykin, John Logie Baird and Philo Farnsworth (some of the inventors of television).
According to Article 1.3 of the Radio Regulations (RR), telecommunication is defined as « Any transmission, emission or reception of signs, signals, writings, images and sounds or intelligence of any nature by wire, radio, optical, or other electromagnetic systems.» This definition is identical to those contained in the Annex to the Constitution and Convention of the International Telecommunication Union (Geneva, 1992).
The early telecommunication networks were created with copper wires as the physical medium for signal transmission. For many years, these networks were used for basic phone services, namely voice and telegrams. Since the mid-1990s, as the internet has grown in popularity, voice has been gradually supplanted by data. This soon demonstrated the limitations of copper in data transmission, prompting the development of optics.
Burton upon Trent, also known as Burton-on-Trent or simply Burton, is a market town in Staffordshire, England, close to the border with Derbyshire. In 2011, it had a population of 72,299. The demonym for residents of the town is 'Burtonian'. Burton is 11 miles (18 km) southwest of Derby, 27 miles (43 km) northwest of Leicester, 28 miles (45 km) west-southwest of Nottingham and 20 miles (32 km) south of the southern entrance to the Peak District National Park.
Burton is known for brewing. The town originally grew up around Burton Abbey. Burton Bridge was also the site of two battles, in 1322 when Edward II defeated the rebel Earl of Lancaster and 1643 when royalists captured the town during the First English Civil War. William Lord Paget and his descendants were responsible for extending the manor house within the abbey grounds and facilitating the extension of the River Trent Navigation to Burton. Burton grew into a busy market town by the early modern period.
The town is served by Burton-on-Trent railway station. The town was also the start and terminus of the now defunct South Staffordshire Line which linked it to Lichfield, Walsall, Dudley and Stourbridge.
