Of course, this bandwidth trade-off requires modifications in the radio's modulation and coding scheme. Figure 1 illustrates the trade-off between system gain and bandwidth in terms of distance vs.

Figure 1: Architecture for a typical GSM/GPRS/EDGE system EDGE enhances the data throughput by a combination of different techniques: EDGE's 8-level phase-shift keying (8PSK) modulation scheme allows ...
