Mesh communications

[Larry Caldwell]

There is a new 900 mhz texting platform that is just getting started. I just ran across it, so don't know much more than videos. There are two architectures that run on the same hardware. The primary advantage of Meshtastic is that it is fully peer-to-peer text forwarding with no recourse to cell towers. Meshcore requires repeaters, which can be solar powered, are cheap, and have to be user installed.

Meshtastic uses peer-to-peer nodes, which work best for local conversations with few hops. Maximum hops 7, default 5.

Meshcore, uses a router architecture, requires router setup, but then can bounce messages hundreds of miles.

No question that the spooks will be monitoring any and all communications, more than likely able to decode encrypted messages or at least know who is communicating with whom.

@Larry Caldwell Thanks for posting this.

A friend built something similar to this to solve a problem he and his neighbors had during several nearby fires that took out cell, internet, and landlines. They have used it to message evacuation warnings and required evacuations. It has worked really well for them.

LoRa is a pretty neat standard, enables some interesting applications, of which this is one.

All the best,

Peter
