Hurricanes are a problem here in Florida and communication can be though during the outage or hours after. My neighbors and I use a specific channel with cheap BaoFengs to check on each other and make sure we are all stocked, but it would be nice to have the ability to text within a group chat (not everyone understands radios, unfortunately).

How can I setup a local area network over radio? I've tried transferring data over the BaoFengs with adapters and a custom app, but it was very slow.



There are lots of tutorials on how to do this with an Arduino and a Lora shield. It just appears as a serial device to the PC. Some friends and I use this type of setup in our car for telemetry in a low budget endurance racing series. It has been pretty bulletproof.


That's sweet, do you have a link to a tutorial?


Here's one: http://wiki.lahoud.fr/doku.php?id=simple_lora_prototype

The radiohead library seems to be the most common. It exposes a reliable datagram API that has worked really well.


Thanks!


We've really become accustomed to the centralized internet. If you aren't on it most of the apps people are used to using don't work.

Using a LAN effectively probably takes more effort than radios.


Look into some LoRa modules with Bluetooth and Meshtastic
