    900MHz WiFi, 20-40Mbps at “10 miles” (what’s that, 16km?). I mean I love the vastly simpler authentication part of the protocol but isn’t it just a mobile cell band at that point?

      Yes and no, it’s true it can get similar distance and somewhat similar data speeds as a cell tower

      But, at 900MHz you don’t need a license to run it so you can do cool things, like a community WiFi mesh kinda like meshtastic, but with real speeds where hosting mesh-only websites and services become realistic

        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.

    I actually just bought my first meshtastic node and of course it uses LoRa and so I’m now diving into the encoding rates and shit like that. The very long slow seems to use 62 kHz of bandwidth and offers a transverse beat of 0.09kbps. However, you get a link budget of -157dB of decoding on that, which is insane.
