Abstract:

With the deepening of industry digital transformation, there are two modes of 5G industry applications worldwide: public network mode and private network mode. The public network mode entirely or partially relies on the operator's frequency or network, while the private network mode relies on dedicated frequencies and private 5G network. At present, Japan, Germany and other countries are promoting 5G industrial applications by the private network mode. Japanese regulators proposed a mode of local 5G private network and issued industry and frequency-related policies. The key demonstration projects were collected to promote local 5G network application. The development of local 5G network in Japan provides a certain reference for the development of private 5G network in China.

Key words: local 5G, middle band, microwave band, 5G industrial application
