What is MeshCore?

INTRODUCTION · OFF-GRID MESH COMMUNICATION

MeshCore — a portmanteau of Mesh (a network of interconnected devices) and Core (nucleus) — is a wireless communication system that operates entirely independently of the internet, mobile networks, or any other existing infrastructure.

It combines LoRa radio technology with advanced mesh networking to enable reliable communication over distances of tens of kilometres.

[!NOTE] Important: MeshCore is a text-based communication system. It is specifically designed for sending text messages, GPS locations, telemetry data, and control commands. Voice calls or video are not supported.

What makes MeshCore unique?

Unlike traditional communication systems, MeshCore requires no central server or access point. Every device in the network simultaneously acts as:

  • A transmitter and receiver — for direct communication
  • A router — forwarding messages on behalf of others
  • An autonomous computer — making decisions without human intervention

This architecture makes the network robust: if one device fails, the network automatically finds an alternative route.

Who is MeshCore for?

  • Families — Stay in touch during travel or emergencies, without depending on a mobile network.
  • Radio amateurs — Digital experiments and emergency communication via LoRa mesh on the 70 cm band.
  • Outdoor enthusiasts — Hikers, campers, and adventurers communicating beyond mobile coverage.
  • Clubs and associations — Morse clubs, hiking groups, or other groups wanting to set up their own mesh.

Open Source with an optional licence

MeshCore is an open-source project under the MIT licence. The core is completely free: mesh routing, end-to-end encryption, room systems, and basic GPS. For advanced features such as remote repeater management, higher zoom levels on maps, and telemetry nodes, a MeshCore Ultra licence (£8, one-time) is available.
