The Very First Generation (1G) of wireless communication is an analog form of technology wherein the signals are modulated to higher frequency to transmit signal from a cellular device to another via base station. Distinct standards were developed in distinct areas, to identify a few – AMPS (Advanced Mobile Phone System) in US, NMT (Nordic Mobile Telephone) in Eastern Europe, TACS (Total Access Communications System) in Great Britain.
Nevertheless, the golden age of wireless mobile application development began in the year 1980’s, that the technology GSM (General System for Mobile Communications), a European standard, first established and intruded on the market. This 2nd Generation (2G) digital communication system has brought regarding the major landmark in innovative technology, making longer space communication potential and simpler to work with. Both cellular equipment vendors and telecommunications operators gained using the growing demands from mobile users.
In GSM, the exchange of voice calls and SMS (Short Messaging System) through a portable or cellular apparatus became widely used worldwide. Its realtime and reliable transfer of information caught the interest of several users, that even the price of services, where voice calls were billed per minute and SMS per message sent, as well as the hardware conditions, for example SIM card and mobile phone, are insignificant for the consumers longing for efficient and dependable communication technology. As an outcome of additional study, GPRS (General Packet Radio Service) came understood in 1990’s.
