What is Meshtastic?
Overview
Meshtastic is an open-source, decentralized communication system that uses LoRa (Long Range) radio to create off-grid mesh networks. It allows devices to exchange messages, location data, and telemetry without relying on cellular service, Wi-Fi, or the internet.
Meshtastic is designed for resilience. Each node can relay messages for others, allowing the network to grow organically and continue functioning even if individual nodes fail.
How It Works
- Uses LoRa radios (typically 915 MHz in the US, 868 MHz in EU)
- Devices form a self-healing mesh
- Messages hop from node to node until they reach their destination
- Encrypted end-to-end using modern cryptography
- Managed via mobile apps (Android/iOS) or desktop clients
Common Use Cases
Emergency & Disaster Communications
When traditional infrastructure fails
Outdoor Recreation
Hiking, hunting, off-roading
Rural & Remote Messaging
Areas without cell coverage
Community Resilience Networks
Tactical, preparedness, and hobbyist projects
Strengths
- Extremely low power consumption
- Long communication range (miles, line-of-sight)
- Mature ecosystem and active community
- Wide hardware support (Heltec, RAK, LilyGO, etc.)
- Strong encryption and privacy
Limitations
- Low bandwidth (text and small data only)
- Not designed for high-speed or real-time data
- Performance depends on node density and terrain
