Description The International Telecommunication Union (ITU), an international civil organization established to standardized worldwide telecommunications, have stated that the superhigh frequency is encountered between 10 cm to 1 cm. Microwaves are part of this frequency, but also include ultra-high frequency (UHF) and extremely high frequency (EHF) signals. Super high frequency electromagnetic waves are relatively short for radio waves. This frequency is used for microwave devices, mobile phones (W-CDMA), WLAN, most modern Radars. The commencing Wireless USB technology will be using aprox. 1/3 of this spectrum. Uses Some uses are IEEE 802.11a Wireless LANs, Satellite uplink/downlinks and terrestrial high-speed data links which are sometimes referred to as "backhauls". External articles ---- | ||||||||
