V band
band of frequencies in the microwave portion of the electromagnetic spectrum
The V band ("vee-band") is a standard designation by the Institute of Electrical and Electronics Engineers (IEEE) for a band of frequencies in the microwave portion of the electromagnetic spectrum ranging from 40 to 75 gigahertz (GHz). 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 600–1,000 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 the frequency band from 57 to 71 GHz for unlicensed wireless systems. These systems are primarily used for high capacity, short distance (less than 1 mile or 1.6 km) 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.
Uses
On December 15, 1995 the V band at 60 GHz 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.
The public source identifies “V band” as band of frequencies in the microwave portion of the electromagnetic spectrum. This brief keeps that definition visible, then builds a research path around band, frequencies and microwave.
Why this record matters
A short description can identify a subject without explaining its stakes. For “V band”, the useful work is to connect “band of frequencies in the microwave portion of the electromagnetic spectrum” to the records capable of establishing context and consequence.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Dec 11, 2025. The linked authority identifier is Q2882172. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1995.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
