I see some 5G New Radio routers shipping with 12 volt 1 amp power supplies, and others with 12 volt 2 amp power supplies, so 12 to 24 watts at most.

Its impressive that you can get a gigabit, WiFi 6 capable router with a new Qualcomm 5G/LTE chipset to fit in such a small power envelope!

Outside (and not that far outside) metro areas in Australia, this wire you speak of is unknown.

In places I’m looking to live, your choices are 5G, “Fixed Wireless NBN” which tops out at around 60-80Mbps and Starlink. I know starlink takes a lot of power.
