Wired communication refer to transmission over a wire communication channel like fiber optic. On the other hand, communication technologies that don't use wire like wifi is known as wireless.
In 1793, Claude Chappe invent the first long-distance semaphore (visual or optical) telegraph line. In 1821, Joseph Wheatstone, invented the first microphone. In 1831, Joseph Henry invented the first electric telegraph. In 1835, Samuel Morse invented Morse code. In 1843, Samuel Morse invented the first long distance electric telegraph line. At the same year, Alexander Bain patents the first fax machine. In 1876, Alexander Graham Bell patents the electric telephone. In 1889, Almon Strowger, patents the direct dial telephone or automatic telephone exchange. In 1894, Guglielmo Marconi, improves wireless telegraphy.
In 1898, the first telephone answering machine was invented. This allows automatic phone call answering while receivers were away. In 1902, Guglielmo Marconi transmits radio signals from Cornwall (UK) to Newfoundland (North America). This is the first radio signal sent across the Atlantic Ocean. In 1906, Lee Deforest invents the electronic amplifying tube or triode. This allowed all electronic signals to be amplified improving all electronic communications. For example, telephones and radios. In 1914, the first cross continental telephone call made. In 1916, First radio with tuners was discovered by using different frequency to communicate with different station. In 1925, John Logie Baird, transmits the first experimental television signal. In 1927, NBC start 2 radios networks and the first television broadcast in England. In 1930, US had its first television broadcast.
In 1949, the first network TV starts in US. In 1966, Xerox invents the Telecopier, the first successful fax machine. In 1969, the first Internet, ARPANET started. In 1972, HBO invents pay-TV service for cable. In 1976, Apple 1 home computer invented and the First nationwide programming via satellite and implemented by Ted Turner. In 1979, the first mobile phone starts in Japan. In 1994, US government releases control of internet and WWW is born.
The future of telecommunication is on the way and changing. The two most visible changes in our telecommunication networks within the foreseeable future will be increase speed and access. With the growth and incresing dependability of wireless network, land lines and the use of copper coaxial cabling will eventually become a thing of the past. Telecommunication industry will soon undergo a shift of wireless and fiber optic technologies which will increase the potential for technology and the services that will be offer by telecommunication company. In addition price will also decrease.Links:
