Comment on The Best Meshtastic Devices for Every Use Case: A Comprehensive Guide
termain@programming.dev 1 month agoMeshtastic® is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source!

How does this differ from walkie talkies?
helenslunch@feddit.nl 1 month ago
It is text-based only. And since it’s such a small amount of data, it can be transmitted a much longer distance.
There’s also the Mesh part where if two nodes (radios) are too far apart, and another node is in between, it can act as an intermediary/relay to increase distance. You can use ~4 nodes (3 hops) in this way.
Communications are also encrypted.

Is 4 nodes the maximum able to connect?
helenslunch@feddit.nl 1 month ago
Not sure what you mean by “connect”. You can connect hundreds of them in a mesh network (although the network will eventually become saturated if you don’t adjust), but message delivery is typically electronically limited to 3 “hops” for any particular message.

Oh this is making some sense to me now. Will this replace or augment iMessage one day?
helenslunch@feddit.nl 1 month ago
Hehe no. It is text/emoji only. Best used in places where cell networks don’t exist, go down, or become saturated, or some combination.

By supporting networking.
As I understand “walkie talkie” radios, the spectrum they use (GMRS/FRS/CB/MURS, etc) isn’t permitted to transmit data in a way that’s useful for proper data networking (there’s some allowance for data but not really anything like what lost people think of as networking, and encryption is right out of the question).

They can transmit any kind of data and be hooked to the internet if you like.

The long range part I guess.
