In addition to the 60-GHz band, there are other very interesting and potentially high-volume millimeter-wave bands.
Licensed E-band
This band is for point-to-point communications, useful for telecommunications backhauls or point-to-point local-area networks. In the US, bands have been set aside at 71-76, 81-86 GHz, and 92-95 GHz. As compared to 60 GHz, the benefits of licensed E-band are (1) the license itself which protects a registered link from interference and (2) operation in a band free from oxygen absorption. An overview article of licensed E-band can be found here.
Vehicular Radar
The 76-77 GHz band is allocated to forward-looking vehicular radar. Such radars are also called “adaptive cruise control” or “collision avoidance” radars, and would provide drivers useful warnings about obstacles in their path. These radars would be an evolutionary step towards intelligent traffic systems.
94-GHz Band
The 94-GHz band could be used for imaging or wireless communications. This band is included in the licensed E-band allocation. Regarding imagers, the wavelength at 94 GHz provides excellent resolution, while many materials, clothes included, are transparent to 94 GHz. This provides an opportunity for various security applications, such as airport screening, provided privacy rights are maintained.
