What is a mesh network?
In a mesh network, nodes relay data for one another so the network can cover long distances without centralized infrastructure. This improves resilience, privacy, and community ownership.
Several ecosystems are active: Meshtastic and MeshCore both use LoRa on ISM bands (e.g., 868 MHz) for long‑range, low‑bitrate links; MeshCom explores interoperable routing; Freifunk focuses on community Wi‑Fi at 2.4/5 GHz.

Luxembourg focus
We document groups, clubs, nodes and gateways across Luxembourg’s communes. Submissions are welcome in LU/FR/DE/EN. If you run a group or deployment, please submit your details.
Regulatory note: Some uses may require an amateur radio license in Luxembourg. See ILR ↗; clubs: LARU ↗, RL ↗.
