GSM Radio Technology Evolution Path

• The new mobile datacom services will differ from the second generation GSM data services in several ways. Perhaps the most essential changes take place in the radio access technology. For example, they support much higher bit rates over the air interface, which is basically made possible by more efficient channel coding and the ability to use multiple time slots. In addition, General Packet Radio Service (GPRS) will bring packet switched communication to GSM. The following chapters describe the GSM Radio Technology evolution steps.
