Could a mesh network be created on existing WiFi hardware? For example with a firmware refresh / OpenWRT? Then it’s just a matter of mass adoption / critical mass in neighborhoods.

Technically yes, practically no. Half duplex in a shared medium radio hardware just does not scale to neighborhood sized meshes well.

  I'm trying to figure out a way to get small messages to transfer over P2P radio: http://radiomesh.org http://radiomesh.org

    I've been having great success with https://www.crowdsupply.com/ronoth/lostik https://www.crowdsupply.com/ronoth/lostik It has both a Lora mode and raw radio mode, I've been utilizing the raw radio mode.

      Ok, neat! What language are you programming in? I'm going to use Java, the tricky parts will be to build the frequency hopping (for me 410-525MHz) + power lowering (-1-+14/+20dBm) parts so that densely populated areas can function properly.

        Largely NodeJS with https://www.npmjs.com/package/serialport https://www.npmjs.com/package/serialport but for some of the more ethernet-centric integrations I've been using C++. I haven't gotten to dynamic frequency setups yet, I've actually been lazy and using 2 of these on each side to act as separated TX/RX in different frequency bands. Certainly doesn't scale past a dozen but it made things a lot easier to get started. I'm curious on your choice of optimization algorithm to balance cell size/interference with relay congestion.
