MeshCore Europe - Off-Grid Kommunikation für Alle
MeshCore ist Open-Source Mesh-Netzwerk-Firmware für LoRa-Geräte. Kommuniziere ohne Internet oder Mobilfunkmasten in ganz Europa mit verschlüsseltem, Peer-to-Peer-Funk.
What is MeshCore?
MeshCore is open-source firmware that runs on small, inexpensive LoRa radio devices. It creates a decentralized mesh network where messages hop from device to device until they reach their destination. No internet connection or cellular service is required.
Private by Design
All messages are encrypted end-to-end using AES-256. No accounts, no phone numbers, no data collection. Your conversations stay between you and the people you talk to.
Works Anywhere
MeshCore operates on the license-free 868 MHz LoRa band in Europe. It works in forests, mountains, at sea, and in urban areas. Typical range is 1 to 10 km line of sight, extended further through repeaters.
Community-Powered
The network grows as more people join. Every device can relay messages for others. Dedicated repeaters, often solar-powered and placed at elevation, extend coverage across entire regions.
Why MeshCore?
No Monthly Costs
Buy a device once (EUR 15-80) and communicate for free, forever. No SIM card, no data plan, no subscription.
Works Without Infrastructure
When cell towers go down, when internet fails, when you are out of range of any infrastructure, MeshCore keeps working.
Open Source
The firmware, the protocol, and the companion app are all open source. Anyone can inspect, modify, or contribute to the code.
Privacy by Design
End-to-end AES-256 encryption. No accounts, no tracking, no data collection. Your messages stay private.
Efficient Routing
Managed flood routing protocol that is more bandwidth-efficient than naive flooding. Messages reach their destination with less congestion.
Community Powered
Operators across Europe build networks together. Local communities coordinate deployments, share knowledge, and welcome newcomers.
How It Works
Get a Device
Purchase a LoRa radio device such as a Heltec V3, LilyGo T-Beam, or RAK WisBlock. Prices range from EUR 15 to EUR 80 depending on the model. Make sure you buy the 868 MHz version for Europe.
Flash the Firmware
Use the web-based flasher at flasher.meshcore.co.uk to install MeshCore firmware on your device. It takes about five minutes.
Start Communicating
Download the MeshCore companion app on Android or iOS. Pair your device via Bluetooth and start sending messages. Join a local room server to connect with other operators in your region.
