Spectrum is the distribution of wavelengths and frequencies.

In scanning and radio frequency uses, we often refer to a bandwidth of spectrum as a "band". These "bands" are frequencies that exist in a continuous range and usually have a common characteristic which identify it as a type of band.

These bands are divided by the area of the spectrum in which they are located. Those "bands" are commonly accepted to conform to the following table:

Abbreviation Name Spectrum
ELF Extremely Low Frequency < 3 kHz
VLF Very Low Frequency 3 - 30 kHz
LF Low Frequency 30 - 300 kHz
MF Medium Frequency 300 kHz - 3 MHz
HF High Frequency 3 - 30 MHz
VHF Very High Frequency 30 - 300 MHz
UHF Ultra High Frequency 300 MHz - 3 GHz
SHF Super High Frequency 3 - 30 GHz
EHF Extremely High Frequency 30 - 300 GHz
