Description

LoRa is an interesting technology. MeshCore/Meshtastic are 2 incompatible firmwares that use cheap and accessible LoRa boards to provide off-grid communication between devices in case of blackout, natural disaster, in case of GSM/LTE signal and internet connection lost. In EU it uses 868MHz free band. The communication is limited to text messaging due to low bandwidth. The nodes can be used as stationary or as mobile trackers. Telemetry can include GPS data or some enviromental sensors.

Goals

Set up 2-3 static nodes with good antennas and coveredge. Use 2 portable nodes to check if they can communicate with each other and what are the limits.

Resources

4 LoRa boards, one Mikrotik Omni 868 v.2 antenna for the main node/repeater, 3x Gizont 10dB antenna.
