Late 2017 China announced their intention to use the 4.8 to 5 GHz for 5G services, along with studying 4.4 to 4.5 GHz band for future 5G applications. The 4.4 to 4.8 GHz band is also of strong interest to Japan, consequently 3GPP standardised n79 (4500 MHz) to harmonise requirements of China and Japan.

In April 2019 Japan completed its auction of the 4.5 GHz band, locking in the n79 band for national 5G deployments.
