Part one and part two of this series covered how Reticulum and MeshCore actually move a sensor reading: LXMF’s delivery methods and Propagation Nodes on one side, a purpose-built sensor role and CayenneLPP encoding on the other. Both are genuinely decentralised, no shared infrastructure required beyond the nodes themselves. This closing part asks the question that decides whether that matters for a given deployment: what does the alternative, LoRaWAN, actually require to do the same job?
