Later 2G releases, often referred to as 2.5G and 2.75G, include General Packet Radio Service and Enhanced Data Rates for GSM Evolution . GPRS allows 2G networks to achieve a theoretical maximum transfer speed of 40 kbit/s (5 kB/s). EDGE increases this capacity, providing a theoretical maximum transfer speed of 384 kbit/s (48 kB/s).
