Definition
LoRaWAN is an open, royalty-free networking protocol standardised by the LoRa Alliance that sits on top of Semtech's LoRa radio modulation. Where LoRa defines how bits travel through the air, LoRaWAN defines the media-access and network architecture: how thousands of battery-powered end devices share airtime, authenticate, encrypt payloads, and route messages through gateways to a network server.
Star-of-stars topology
A classic LoRaWAN deployment is not a peer mesh. End devices broadcast to any gateway in range; gateways forward those packets over IP backhaul to a central network server, which de-duplicates and decrypts them. This star-of-stars design keeps the end nodes extremely simple and power-frugal, often running years on a coin cell. Devices are grouped into Class A, B, and C profiles that trade downlink responsiveness against battery life.
Security and sovereignty trade-offs
LoRaWAN provides AES-128 end-to-end encryption by default, which is attractive for sovereign telemetry. However, its reliance on internet-connected gateways and central servers means a public LoRaWAN network reintroduces an infrastructure dependency. Sovereign builders often prefer self-hosted private LoRaWAN servers, or skip LoRaWAN entirely in favour of fully peer-to-peer mesh firmware that uses the same LoRa radios without any central coordinator.
Compare LoRaWAN's gateway model with the decentralised approach described under mesh routing, and review the underlying radio at LoRa.
