5G devices per square mile

In general, you can connect up to 32 devices to 5GHz WiFi simultaneously, but this also depends on your router. Some routers have support for over 250 devices; others only support up to 10. Your Internet speed also affects how many devices can be used practically on the 5GHz band.

5G Supports Lots of Devices At a minimum, 5G must support 1 million devices for every square kilometer (0.386 square miles). This means that within that amount of space, the network is capable of connecting a whopping 1 million or more devices to the internet at the same time.
