I mean, your smartphone already knows how to talk on 600 megahertz, 700 megahertz, 800 megahertz, 1.7 gigahertz, 1.9 gigahertz, 2.1 gigahertz, 2.4 gigahertz, 3 gigahertz, 5 gigahertz, 6 gigahertz, etc. I see absolutely no reason it would be unable to talk on 915 megahertz.
I’m just learning about, but their website saying it connects through “[…] Wi-Fi or Tor” left me a bit upset.
The way I understand it is that it can connect to local devices with Bluetooth. It can connect to local devices on the same Wi-Fi network or it can connect over the internet using Tor. What it seems like meshtastic has over Briar is the fact that LORA is much longer range than Wi-Fi or Bluetooth.
