Frequency Band


A frequency band refers to an interval in the radio spectrum denoted by a lower and upper limit. For example, the AWS-1 band consists of 90 MHz in the AWS spectrum ranging from 1710–1755 MHz and 2110–2155 MHz.

The radio spectrum exists in the lower ranges of the electromagnetic spectrum. It’s the medium on which both analog and digital wireless communications systems are based. These include everything from radio to mobile networks and satellite systems.

Below is a table showing the fundamental frequency band designations across the electromagnetic spectrum as classified by the International Telecommunications Union (ITU):

Designation Frequency Wavelength
Very Low Frequency (VLF) 3 kHz–30 kHz 100 km–10 km
Low Frequency (LF) 30 kHz–300 kHz 10 km–1 km
Medium Frequency (MF) 300 kHz–3 MHz 1 km–100 m
High Frequency (HF) 3 MHz–30 MHz 100 m–10 m
Very High Frequency (VHF) 30 MHz–300 MHz 10 m–1 m
Ultra High Frequency (UHF) 300 MHz–3 GHz 1 m–100 mm
Super High Frequency (SHF) 3 GHz–30 GHz 100 mm–10 mm
Extremely High Frequency (EHF) 30 GHz–300 GHz 10 mm–1 mm

Cellular frequency bands exist in the spectrum interval between 3 kHz and 300 GHz. But in general, the Ultra High-Frequency band (UHF) is the most significant frequency band to modern wireless communication systems.

The UHF frequency band is used in Wi-Fi networks, satellite TV, GPS, and mobile communication systems like GSM, CDMA, and LTE.

Example of Frequency Band in a sentence

"Frequency bands beyond 3 GHz are more prone to interference which necessitates a line of sight requirement."

Synonyms: radio band
