This router can handle up to 4G. A 5G router would be for example this model here. 5G routers have a higher bandwidth. With such a router and e.g. external antennas, you can improve reception and increase the range compared to most end devices. However, the connection quality depends on the region and on how many devices are connected to the antenna and how many interfering factors are present between the router and the antenna mast, etc.
