Meshtastic – an open-source mesh networking platform redefining communication. From decentralized, long-range capabilities to versatile applications in emergency response, outdoor adventures. Discover the diverse hardware options, step-by-step setup guide, and the remarkable range of 5 KM - 10 KM.
What exactly could I use this for? I know how LoRaWAN works, but it requires entrypoints into the internet. Does Meshtastic need these? Do I have to set up two nodes to use it for anything? Does it use existing LoRaWAN infrastructure?
Its a totally separate thing from LoRaWAN. Its useful for messaging across town (if you live in an area with enough nodes), and it can do things like report on temperature an humidity or when a sensor is tipped, some devices support GPS too.
You wouldn’t need internet access for these to work, although there is a public community WAN server you could join to operate under MQTT (which is their internet facing WAN function). They function off of LoRa RF on the 915mhz band in the U.S. (and other bands elsewhere) to do the bulk of the communication. BLE is also utilized for management.
These do need more than 1 node to operate properly, but since it works off the concept of a public mesh (with options to privatize), you don’t need two of your own devices in a developed location.
However, if no one is around or within line of sight… then you’ll have to work a little harder to get contacts/connections going.
For now, yes. There are certain extensions and 3rd party plugins that are seeking to expand on that by adding BBS capability or JS8call (for expanded text & basic audio).
There’s limited bandwidth to work with on just the 915mhz band but you’d be surprised what you can push downstream.
