Who uses mmWave?

Though mmWave can be readily used in stationary scenarios such as indoor hotspots or backhaul, it is challenging to use mmWave in mobile networks, where the transmitting/receiving nodes may be moving, channels may have a complicated structure, and the coordination among multiple nodes is difficult .

Millimeter-wave (mmW) frequencies (30–300 GHz) are being used for many applications in the modern world. These applications include,but not are limited to, radio astronomy, remote sensing, automotive radars, military applications, imaging, security screening, and telecommunications.

The three U.S. carriers use different names for the 5G services that utilize mmWave technology: AT&T’s mmWave 5G is named 5G Plus (5G+), Verizon launched 5G Ultra Wideband (5G UWB) using mmWave, while T-Mobile uses Ultra Capacity 5G as the name for the combined service using both its mid-band and mmWave networks, but …

Millimeter wave (mmWave) communication systems have attracted significant interest regarding meeting the capacity requirements of the future 5G network . The mmWave systems have frequency ranges in between 30 and 300 GHz where a total of around 250 GHz bandwidths are available.
