The 60-80 GHz ITU wireless band, as defined by the ITU Radio Regulations ITU-R F.2006 and ITU-R F.1497, is a frequency band allocated for wireless communication within the range of 55.78 to 85.875 GHz. This band, also known as the E-band, is particularly suited for high-capacity wireless networks due to its large bandwidth and small wavelength. The ITU-R F.2006 outlines the technical characteristics of the band, while the ITU-R F.1497 provides guidelines for sharing the band between different services. The regulations aim to ensure efficient use of the spectrum and prevent harmful interference. The 70-80 GHz band is often used for applications such as fixed wireless access, high-speed wireless local area networks, and backhauling for mobile networks. Many countries offer this spectrum under a "light licence" framework.
