Meshtelastic is an app that enables devices to send text messages over long distances without requiring Wi-Fi or cell service, using Long Range radio (LoRa) nodes to pass messages along over free radio frequencies.
Messages are end-to-end encrypted, can be sent to groups or individuals, and the network has the added option of location-tracking.
Most devices currently on the market need to be paired with a phone over Bluetooth to function, but some are standalone gadgets that are a radio, antenna and battery, with the expectation that users make the housing themselves.
The software is open source, but it has some limitations, such asraw bandwidth, the need to have the device in range of at least one other radio for it to work, and that it’s unlikely to “replace the internet” as it can only send text messages.
