In C program, convert frequency bands in radio spectrum to codes

Radio frequency (RF) is the oscillation of AC current or AC voltage or any other oscillating body in the frequency range of 20KHz to 300 GHz. p>

The radio spectrum of a device is the range of frequencies that a device can capture, process, or reproduce. The general frequency range is 20Hz to 20KHz.

The frequency band is the frequency range divided from extremely low frequencies to extremely high frequencies. These bands are small ranges of frequencies used to provide a small portion of the spectrum.

Frequency bands in the radio frequency spectrum

Frequency range is a continuous range with an upper frequency limit. In the radio spectrum, there are several frequency ranges that are different from each other.

In the radio spectrum, the following ranges are defined based on their frequency range, applications, etc.

Basically used for communication, these play a huge role in wireless communication.
