Introduction
Meshtastic® 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 it works
Meshtastic utilizes LoRa, a long‑range radio protocol that is widely accessible in most regions without the need for additional licenses or certifications, unlike ham‑radio operations.
These radios rebroadcast messages they receive, forming a mesh network. This setup ensures that every group member, including those at the furthest distance, can receive messages.
A Meshtastic radio can be paired with a single phone, allowing friends and family to send messages directly to that radio. Each device supports a connection from only one user at a time.
