My first experience was at a NOC (Network Operating Center). Before going into details of that I would like to give a brief on 2G and 3G.
GSM is used to describe technologies for Second Generation (2G) digital cellular networks. First Generation (1G) is an analog cellular network. In 2G standard originally described a digital, circuit switched network optimized for full duplex voice telephony. It was further developed for packet data transfer via GPRS (General Packet Radio Services). EDGE (Enhanced Data rates for GSM Evolution) gives more increase in data transfer. Later 3G was introduced.
