Bands in Radio frequency Spectrum

In the radio frequency spectrum, Band is also called frequency. Band is a specific range of frequencies in which the frequencies is divided from very low frequency to extremely high frequency and each band has their upper and lower frequency limit.

For example, very low frequency, low frequency (with their frequency range 3KHz-30KHz and 30KHz-300KHz respectively) etc.




Frequency Range:
A continuous range or spectrum of frequencies that extends from one limiting frequency to another. There are different type of frequencies in RF which are different from another.

The difference between among them are given below on the basis of their frequency ranges, propagation and their applications (where these frequencies are used) respectively.

Bands Frequency Range Propagation Application
Very Low Frequency (VLF) 3KHz-30KHz Ground Long range radio navigation
Low Frequency (LF) 30KHz-300KHz Ground Radio Broadcasting and navigational locator
Medium Frequency (MF) 300KHz-3MHz Sky Radio Broadcasting, AM Radio, Land
High Frequency (HF) 3MHz-30MHz Sky Citizen band/Aircraft/Ship Communication
Very High Frequency (VHF) 30MHz-300MHz Sky and Line of sight Amateur Radio, Radio Navigation, VHF T.V. and FM Radio
Ultra High Frequency (UHF) 300MHz-3000MHz Line of sight VHF T.V., cellular Phone, Paging, Satellite
Super High Frequency (SHF) 3GHz-30GHz Line of sight Mobile, Radio Navigation, Space and Satellite Communication
Extremely High Frequency (EHF) 30GHz-300GHz Line of sight Radar, Amateur radio, satellite and space exploration
