  • High QAM rate = more throughput
  • Lower modulation allow smaller antenna size.

Quadrature amplitude modulation (QAM) is an analog and a digital modulation scheme, used extensively as a modulation scheme for wireless digital telecommunication systems.  Arbitrarily high spectral efficiencies can be achieved with QAM by setting a suitable constellation size, limited only by the noise level and linearity of the communications channel.

Eband is limited to QAM rate of 64.
