The Wi-Fi standard 802.11ah (a.k.a. Wi-Fi HaLow) has not played much of a role in Europe thus far, even though the 802.11ah standard uses a frequency that makes it quite suitable for long-range networking. However, the available bandwidth differs significantly across regions.
You can run 5g on unlicensed spectrum too, and there are fully open source 5g stacks. The primary issue there is that most phones don’t have the hardware to connect to those networks. But the same is true right now of wifi on 900 MHz.
Right, but ah to ah mesh, then ac WAPs at opportune locations. This will allow communities to connect to one another, and have local access to current devices. This ah looks pretty amazing tbh
