These frequencies are typically used for short-haul connectivity. The higher bands within the range often make wider channels available – 112 MHz and even 224 MHz.

Engineering-wise, millimeter waves reside in the 30-300 GHz range. When discussed in the context of wireless transmission, these refer to bands of 57 GHz and above.
Millimeter waves have evolved as an extremely cost-effective solution for ultra-high-speed connectivity for short ranges.
The 57–66 GHz band is referred to as V-Band. The 71–76 and 81–86 GHz bands are referred to as E-Band.
W-Band refers to the spectrum around 100 GHz, and D-Band refers to the frequency range of 130-175 GHz.
Different uses of V-Band and E-Band are based on the propagation characteristics of the two bands and the available distance derived from them.
V-Band has a much shorter range and is typically used for intra-campus connectivity, surveillance camera infrastructures or small-cell backhaul.
E-Band has a significantly higher range and can be used for business customer access, cell site connectivity or fiber backup.
Generally, the higher the frequency band and the wider the channel, the greater the throughput. In E-Band, wide channels are available, with channel spacing ranging from 62.5 MHz up to 2000 MHz (or 2 GHz). It can handle 10 Gbps using a single 2 GHz c hannel.

E-Band implementation is more challenging for longer links due to high attenuation, which results in reduced availability. Multiband resolves this challenge by combining a microwave carrier with an E-Band carrier, thus achieving both high capacity and high availability for longer distances.
