From the discussion above it can be concluded that, for a given signal-to-noise/ interference ratio, a certain combination of modulation scheme and channel-coding rate is optimal in the sense that it ...

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 ...

Also, it’s important to pick a device that supports a higher modulation index. 802.11ac supports 256-QAM (quadrature amplitude modulation) that enables higher throughput in 802.11ac devices ...
