MeshCore is an open-source, decentralized mesh radio platform that
enables secure, text-based communication without cell towers or the
internet. It uses "Long Range" (LoRa) radio hardware to send messages
over miles by routing them through a network of neighboring repeaters,
making it ideal for off-grid, emergency, or remote communication.

- Off-Grid Communication: Operates independently of infrastructure,
using low-power, long-range (LoRa) radios.
- Secure & Private: Messages are encrypted end-to-end.
- Structured Routing: Unlike some other mesh networks, MeshCore
is optimized for large-scale meshes, often utilizing fixed repeater
nodes on high points for better coverage.
- Role-Based Firmware: Devices can be configured for specific roles,
such as a "companion" (paired to a phone) or a "repeater" (to extend
the network).
- Compatibility: Works on over 50+ different LoRa-enabled devices.
- Most hardware is affordable and off-the-shelf.
- You will want a radio configured as a "Companion"
- Free Companion apps for Android, iOS, macOS, Windows, Linux, and Web.
- Setup takes only about 15 minutes for first node. Local help available!
