LoRa, LoRaWAN, and Meshtastic are often confused, but they operate at different layers of the communication stack. LoRa is a physical-layer radio modulation scheme defining RF signal conversion and spectral spreading. It handles transmission but lacks addressing or routing. Success depends entirely on RF physics like path loss and antenna placement—no network protocol can overcome a poor link budget.

Above LoRa sits LoRaWAN, a managed MAC and network layer protocol. It creates a centralized "star-of-stars" network with gateways and servers, handling device identity, join procedures, and regulatory compliance. This makes it ideal for telemetry and asset tracking but unsuitable for peer-to-peer coordination or decentralized messaging.

Meshtastic operates at the application and mesh routing layer. Using LoRa radios for transport, it adds multi-hop routing, peer-to-peer messaging, and channel encryption without needing gateways. Its reliability is topology-dependent, contrasting with LoRaWAN's centralized management. Understanding these distinct layers is critical for avoiding common deployment failures.
