According to the IEEE nomenclature, two different frequency bands are designated for the V-band: The frequency range between 40 GHz and 75 GHz and the frequency band from about 180 GHz to 280 GHz. The wavelength range for the lower frequency band is between 0.85 cm and 0.4 mm.
This frequency range alsoincludes the 60 GHz band, which is increasingly used by IEEE for radio networks and radio transmissions. The frequency range has a high free space attenuation because the electromagnetic waves experience molecular scattering due to humidity and are strongly attenuated by the atmosphere. It is 108 dB at 60 GHz at a distance of 100 m.
The V-band lies above the Q-band, whose frequency range overlaps parts in the Ka-band and the V-band. Both bands, the Q-band and the V-band are jointly referred to as the Q/V-band in satellite communications. No V-band is listed in the nomenclature of the International Telecommunication Union( ITU).
