Super high frequency (or SHF) refers to radio frequencies (RF) in the range of 3 GHz and 30 GHz. Also known as the centimeter band or centimeter wave as the wavelengths range from ten to one centimeters.

[edit] Description

The International Telecommunication Union (ITU), an international civil organization established to standardized worldwide telecommunications, have stated that the superhigh frequency is encountered between 100 mm to 10 mm. Super high frequency electromagnetic waves are relatively short for radio waves. This frequency is used for microwave devices, WLAN, most modern radars. The commencing Wireless USB technology will be using approximately 1/3 of this spectrum.

[edit] Uses

Some uses are IEEE 802.11a wireless LANs, satellite uplinks/downlinks and terrestrial high-speed data links which are sometimes referred to as "backhauls".
