Fun fact you can build a mesh without dedicated hardware via the Batman protocol using soup cans and home wifi routers ✌️

🌐 Bridging Bitchat + MeshCore: Resilient communication when infrastructure fails Bitchat = Bluetooth mesh on phones you already have (~100m range) MeshCore = LoRa long-range mesh (km+ with cheap hardware) The bridge connects them. Your phone talks to the city-wide mesh network. Perfect for disasters, protests, internet shutdowns.

And you can use WiFi HaLow to get LoRa like ranges with a much higher throughput.

You can use something like @BitSatRelayHQ to get global connectivity and you can use something like @TollGate to transfer the cost of said connection to the user of the infracture

Yes, this is very cool. I've been a fan of freifunk. This will be a fairly small network though, we've done 400km with Meshcore cross country with just a handful of repeaters.
