Sub-THz Bands | Sub-THz Frequencies

This page mentions Sub-THz Bands and Sub-THz Frequencies. These bands and frequencies are used in various sub-terahertz (Sub THz) systems.

About Terahertz (THz) : The term terahertz refers to frequencies in the range 1012. One THz equals 1012 Hz (i.e. Hertz). The frequency spectrum from 100 GHz to 10 THz (i.e. 10000 GHz) is referred as terahertz spectrum. The terahertz wavelength is from 3 mm and 30 µm. Terahertz radiation is non-ionizing in nature and it has lower photon energy compare to X-ray.
About Sub-THz : The frequency spectrum ranges between 90 GHz and 300 GHz is referred as sub-THz spectrum.

Terahertz in EM sepectrum

The sub-THz spectrum enables very high data rate (~1 Tbps) wireless communication system. It offers higher bandwidth which is several tens of GHz.

The sub-THz radio spectrum has been used for various scientific applications such as satellite services, astronomy, earth exploration, meterology etc. Now-a-days sub-THz is being explored for wireless communication systems to deliver higher data rates. The sub-THz frequency range from 90 to 275 GHz is used in fixed and mobile radio communication services.

Sub-THz Frequencies and Sub-THz Bands

Following are the sub-THz bands which covers range of sub-THz frequencies for various applications.
W-Band : The sub-THz frequency range from 92 to 115 GHz is referred as W-Band.
D-Band : The sub-THz frequency range from 130 to 175 GHz is referred as D-Band.
