10 MHz
64.8 Kbps
11 Mbps
VHF and UHF both have advantages and disadvantages, usually the advantages for one is the disadvantage for the other and vise versa.
1 Mbps
5 MHz
54 Mbps
12.5 KHz

10. QAM Modulation
Conveys 2 digital bit streams by modulating the amplitudes of two carrier waves
2 carrier waves (sinusoids) are out of phase by 90 degrees = Quadrature
The modulated waves are summed, and the resulting waveform is a combination of both phase-shift keying and amplitude-shift keying
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.
QAM (Quadrature Amplitude Modulation)

11. QAM Modulation 4-QAM, 16-QAM, 64-QAM
Constellation points are arranged in a square grid with equal vertical and horizontal spacing
Higher order Constellation = more bits per second
Requires constellation points be closer together
More susceptible to noise and corruption
Higher order QAM delivers more data at expense of reliability
Affected by RF noise and multipathing
QAM (Quadrature Amplitude Modulation)
