2.5 generation (mobile communications) (2.5G)

Mobile communications networks and their technologies are divided into generations. While the 2nd generation(2G) networks are based on the Global System for Mobile Communications( GSM) and the 3rd generation( 3G) networks are formed by UMTS, the 2.5th generation networks are about migration from GSM to UMTS. For this reason, mobile networks with data packet switching were inserted between the 2nd and 3rd generations. These are General Packet Radio Service( GPRS) and Enhanced Data Service for GSM Evolution( EDGE), both of which use the infrastructure of the GSM standard.
