The Radio Frequency (RF) spectrum is a limited natural resource. The set of radio frequencies is called the 'RF spectrum.' Theoretically the RF spectrum extends from 9 KHz to 3000 GHz. However, the limitation of the RF spectrum comes from a few critical factors. First of all, various radio frequencies have different propagation characteristics, and hence, their suitability for different types of requirements.
