GPRS : Main ImprovementsGPRS : Main Improvements Higher transmission rates
four new coding schemes allow different data rates ofCS-1 9.05 kbit/s, CS-2 13.4 kbit/s (in 10/00)
CS-3 15.6 kbit/s, CS-4 21.4 kbit/s (in E/01) channel combining
Increased radio resource efficiency radio resources will be used only during data transmission shared access of the same channel
Connection of GSM and IP world Volume dependent charging Faster session set-up Always connected
