# mesh-plans

Meshtastic / Meshcore research and plans.

## Basic plan

I want to build an off-grid, movable, solar-powered station for LoRa based mesh networking and ADS-B receiving.

### Functional requirements

The system should be able to:
- Receive and decode 1090MHz ADS-B signals
- Send and Receive 868MHz LoRa Signals for Mesh networking
- Be maintainable from a remote position
