Super high frequency

The super high frequency or centimeter wave (in English: Super High Frequency, SHF) is a band of the electromagnetic spectrum that occupies the frequency range from 3 to 30 gigahertz, possessing a wavelength of between 10 and 1 centimeter (from which the name of band or centimeter wave is derived).

Description

The International Telecommunication Union, an international civil organization established to standardize telecommunications worldwide, has established that super-high frequencies are located between 10 and 1 centimeter. Microwaves are part of these frequencies, but also include ultra high frequencies (UHF) and extremely high frequencies (EHF). Superhigh frequencies are relatively short for radio waves. These frequencies are used for microwave devices, mobile phones (W-CDMA), WLAN, and the latest generation radars. The Wireless USB standard will use approximately 1/3 of this total portion of the radio spectrum.

Uses

Some uses are IEEE 802.11a/b/g/n/ac Wireless LANs, satellite uplinks and downlinks, and high-speed terrestrial links (sometimes known as "backhauls &#3. 4;).

Super High Frequency Characteristics

In this band propagation by direct optical path occurs.

Systems operating with super high frequency
