Millimeter wave spectrum is already in use in 5G networks in the U.S., and is expected to see wider use around the world in the coming years. According to a November 2020 report from the Global mobile Suppliers Association, there are 120 operators around the world which hold spectrum licenses for airwaves above 24 GHz, and only two dozen have thus far used that spectrum to deploy 5G networks. Meanwhile, 19 countries have specific plans to assign spectrum above 24 GHz between now and the end of 2022.
