The V band (vee-band) of the electromagnetic spectrum ranges from 40 to 75 GHz. Provision No 21 of the ITU Radio Regulations states 21 The Radio spectrum shall be subdivided into nine frequency bands which Very low frequency or VLF refers to radio frequencies (RF in the range of 3 KHz to 30 KHz. Low Frequency or LF refers to Radio Frequencies (RF in the range of 30 kHz&ndash300 kHz Medium frequency ( MF) refers to radio frequencies (RF in the range of 300 kHz to 3000 kHz High frequency (HF radio frequencies are between 3 and 30 MHz. Very high frequency (VHF is the Radio frequency range from 30 MHz to 300 MHz. Super high frequency (or SHF) refers to radio frequencies (RF in the range of 3 GHz and 30 GHz Extremely high frequency is the highest Radio frequency band.

Super high frequency (or SHF) refers to radio frequencies (RF in the range of 3 GHz and 30 GHz Extremely high frequency is the highest Radio frequency band. Radio waves are electromagnetic waves occurring on the Radio frequency portion of the Electromagnetic spectrum. This is article is about the wireless term For other uses see A band (disambiguation. The B band is the range of radio frequencies from 250 MHz to 500 MHz in the Electromagnetic spectrum. C band is a name given to certain portions of the Electromagnetic spectrum, as well as a range of Wavelengths of Light, used for communications D band is the range of radio frequencies from 1 GHz to 2 GHz in the Electromagnetic spectrum. The NATO E band is the range of radio frequencies from 2 GHz to 3 GHz in the Electromagnetic spectrum. The F band is the range of radio frequencies from 3 GHz to 4 GHz in the Electromagnetic spectrum. NATO G band The G band in the modern (NATO/EU sense is the range of radio frequencies from 4 GHz to 6 GHz in the Electromagnetic The H band is the range of radio frequencies from 6 GHz to 8 GHz in the Electromagnetic spectrum. The I band is the range of radio frequencies from 8 GHz to 10 GHz in the Electromagnetic spectrum. The J band is the range of radio frequencies from 10 GHz to 20 GHz in the Electromagnetic spectrum. NATO K band The NATO K band is defined as a frequency band between 20 and 40 GHz (7 NATO L band The NATO L band is defined as the frequency band between 40 and 60 G[[Hertz Hz]] (5–7 The M band is the range of radio frequencies from 60 GHz to 100 GHz in the Electromagnetic spectrum. Radio waves are electromagnetic waves occurring on the Radio frequency portion of the Electromagnetic spectrum. High frequency (HF radio frequencies are between 3 and 30 MHz. Very high frequency (VHF is the Radio frequency range from 30 MHz to 300 MHz. NATO L band The NATO L band is defined as the frequency band between 40 and 60 G[[Hertz Hz]] (5–7 The S band ranges from 2 to 4 GHz, crossing the (artificial boundary between UHF and SHF at 3 C band is a name given to certain portions of the Electromagnetic spectrum, as well as a range of Wavelengths of Light, used for communications The X band is part of the Microwave region of the Electromagnetic spectrum. The Ku band ( pronounced "kay-yoo") is a portion of the Electromagnetic spectrum in the Microwave range of frequencies NATO K band The NATO K band is defined as a frequency band between 20 and 40 GHz (7 The Ka band (Pronounced "Kay-A Band" covers the frequencies of 26 The W band of the Microwave part of the Electromagnetic spectrum ranges from 75 to 111 GHz. The electromagnetic (EM spectrum is the range of all possible Electromagnetic radiation frequencies The V band is not heavily used, except for millimeter wave radar research and other kinds of scientific research. It should not be confused with the 600–1000 MHz range of Band-V (band-five) of the UHF frequency range.
The V band is also used for high capacity terrestrial millimeter wave communications systems. In the United States, the Federal Communications Commission has allocated frequency at 60 GHz for unlicensed point-to-point fixed wireless systems. These systems are primarily used for high capacity, short distance (less than 1 mile) communications. In addition, frequencies at 70, 80, and 90 GHz have been allocated as "lightly licensed" bands for multi-gigabit wireless communications. All communications links in the V band require unobstructed line of sight between the transmit and receive point, and rain fade must be taken into account when performing link budget analysis. Rain fade refers primarily to the absorption of a Microwave Radio Frequency (RF signal by atmospheric rain snow or ice and losses are especially prevalent A link budget is the accounting of all of the gains and losses from the transmitter through the medium (free space cable waveguide fiber etc
Notable Uses
On Dec. 15, 1995 the V band at 60Ghz was used by the world's first crosslink communication between satellites in a constellation. This communication was between the U. S. Milstar 1 and Milstar 2 military satellites. [1]
