The next-generation high-speed, large-capacity communication standard 5G has been in service in Japan since March, but the problem is that the area where it can be used is limited.
Under these circumstances, the Ministry of Internal Affairs and Communications approved a plan to provide 5G services using the current 4G base station to two mobile phone companies, KDDI and Okinawa Cellular Telephone, which is headquartered in Naha City, on the 9th.
In August, the Ministry of Internal Affairs and Communications changed the system so that 5G services can be provided at the frequencies used in 4G, and this is the first time that a plan has been approved under this system.
When providing 5G services using 4G frequencies, the communication speed remains 4G, but the area where 5G can be used can be expanded at an early stage, many terminals can be connected at the same time, and there is a delay when exchanging data. It has the advantage of being almost nonexistent.
The Ministry of Internal Affairs and Communications wants to support the spread of 5G by having 4G base stations utilized.
