If it was not for it for these channels of communication and data transmission, we would probably still be in an era where technology is not as advanced as it is today. Right from that point of time, the concept of communication using a telephone has evolved into first long distance telephone calls (at a distance of 6 miles) in 1876, Motorola’s first handheld mobile phone or cell phone in 1973, 1G or first generation analogue cellular network in 1979 in Japan, 2G or the second generation digital cellular network based on GSM technology in 1991, 3G or the third generation mobile communication based on UMTS and CDMA technologies in 2001 and the currently used 4G or fourth generation mobile communication technology based on LTE standard in 2009. We all talk about the speed of 4G
