The required bandwidth is related to bit rate and the modulation order M. It is so that the double sided bandwidth w = symbol rate= bit rate rb/ divided by the number of bit per symbol n . The number of bits per symbol is = log 2M with M is the M is the QAM modulation order.

Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies . It is typically measured in hertz, and depending on context, may specifically refer to passband bandwidth or baseband bandwidth.
