Table 3:
GPRS Coding schemes and maximum network data rates over air interface
Please note that the values listed above are the maximum ratings which, in practice, are influenced by a
great variety of factors, primarily, for example, traffic variations and network coverage.
EDGE is four times as efficient as GPRS. GPRS use four coding schemes (CS-1 to 4, see table 2)
while EDGE use nine Modulation and Coding Schemes (MCS-1 to 9, see table 2.1).
