Meshtastic is a mesh networking protocol that uses LoRa radios to enable long-range, low-power communication without relying on existing infrastructure.

Meshtastic devices communicate by forming a mesh network where each node relays messages to others, extending the reach across kilometers. This approach bypasses cell towers and WiFi, making it ideal for off-grid or disaster scenarios. The system encrypts messages for privacy and allows users to connect via Bluetooth to control nodes using smartphones or computers. This design empowers decentralized communication in places where traditional networks fail.
