What gets me really excited is the idea of messaging in low internet connectivity areas (aeroplanes (to someone else on the plane)) on the subway/underground
The idea of Bluetooth/WiFi direct mesh, with “internet gateway” devices (maybe those people are rewarded in some way)
In this dream of mine, people can communicate, send data, through non ideal internet conditions (maybe one person on an aeroplane has internet, and they are the gateway for others)
There may be some relay servers running on AWS or whatever, but people could also run their own relays (I guess all devices are a relay)
I’ve tried to get this working myself, using a library called “reticulum” I found in GitHub (good library, but I couldn’t get Bluetooth/WiFi mesh working)
So you want to engineer wireless specifications because internet isn’t always everywhere. Just hook into Amazons sidewalk network this is about your only option. It’s basically LoRa
