The IEEE V Band refers to a specific range of frequencies within the electromagnetic spectrum, designated by the Institute of Electrical and Electronics Engineers (IEEE). This band spans frequencies from 40 GHz to 75 GHz. It is primarily used for high-capacity, short-range communication systems, such as point-to-point wireless links, mmWave radar, and advanced imaging systems. In the context of telecommunications, the V Band is notable for its ability to support high data rates due to the large amount of available bandwidth. However, it is also characterised by higher atmospheric attenuation, particularly due to oxygen absorption, which limits its effective range. This makes it ideal for applications requiring high bandwidth over relatively short distances.
The IEEE V Band range of 40 to 75 GHz should not be confused with the term "E Band" as commonly used on 60 GHz technologies such as mmWave and WiGig. E Band in this context refers to the Waveguide E-Band, a frequency range corresponding with the dimensions of the WR12 waveguide.
