The multiplexed signal is then sent into a multiple-access transmission channel. Telecommunications is the merging of voice, data (WAN), LAN, video, image, and wireless communications technologies with PC and microelec- tronic technologies to facilitate communications between people or to deliver entertainment, information, and other services to people. 0000003281 00000 n

But ordinary voice communications taking place by way of a telephone are not in binary form; neither is much of the information gathered for transmission from a space probe, nor are the television or radio signals gathered for transmission through a satellite link. The telecommunications infrastructure in a building consists of two systems: Telecommunications spaces and pathways ( e.g. Telecommunications, also known as telecom, is the exchange of information over large distances. All forms of telecommunications use different types of electro-magnetic energy and the principle types of transmission media are: Electrical signals over metallic wires; Radio waves through the air and space; Since ancient times, human beings have sought means to communicate at a distance.
