These two telecom trends answer a more general tendency towards an envisioned world centered on communications, where possibly mobile users are willing to be immersed in a pervasive, ubiquitous, and always-connected environment fully supporting information/service sharing based on community belonging. An arrangement which is made up of two or more station with equal number of transmitter and receiver devices is a telecommunication system. 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. ci>-j$dd&3} 6=~8mire}P;SJgZg?UM5OTR^EAlFpWu1_>0S}QuxR#V!Khi3jgHj18Hl([9|%x/vy-a8L :QfJ$w G)\} Digital transmission is employed in order to achieve high reliability and because the cost of digital switching systems is much lower than the cost of analog systems.
