LoRa vs LoRaWAN: What's the Difference?
This is one of the most common points of confusion for newcomers. LoRa and LoRaWAN are related but completely different things. MeshCore and Meshtastic use LoRa - not LoRaWAN. Understanding the distinction helps explain why mesh networking is fundamentally different from IoT sensor networks.
LoRa: The Physical Radio Layer
LoRa refers specifically to Semtech's Chirp Spread Spectrum modulation technology. It defines how bits are encoded onto radio waves. Any software protocol can use LoRa as its radio layer - LoRaWAN uses it, and so do MeshCore and Meshtastic.
Think of LoRa as the engine. Multiple different vehicles can use the same engine.
LoRaWAN: A Centralized IoT Network Protocol
LoRaWAN is a specific network architecture built on top of LoRa, designed by the LoRa Alliance for IoT (Internet of Things) deployments:
- Topology: Star - devices talk to gateways; no peer-to-peer relaying (an optional single-hop Relay extension exists but is rarely deployed)
- Infrastructure required: Gateways and backend servers (The Things Network, Chirpstack, etc.)
- Internet dependency: Gateways connect to the internet to reach the network server
- Use cases: Smart meters, asset tracking, environmental sensors, industrial monitoring
- Encryption: AES-128 with separate network and application session keys, managed via the network/join server
- Messaging: Sensors send data to servers - not person-to-person communication
If there is no gateway in range, a LoRaWAN device cannot communicate at all. It cannot mesh - at most an optional single-hop Relay extension exists, which is rarely deployed.
LoRa Mesh (MeshCore & Meshtastic): Decentralized Peer-to-Peer
MeshCore and Meshtastic use LoRa radio but implement their own peer-to-peer mesh networking protocols on top of it:
- Topology: Mesh - every node can relay for other nodes
- Infrastructure required: None - no gateways, no servers, no internet
- Works completely off-grid: Yes, by design
- Use cases: Off-grid messaging, emergency communications, outdoor recreation, community networks
- Encryption: Group channels use pre-shared keys (Meshtastic); direct messages use per-node public-key encryption (Meshtastic v2.5+, MeshCore)
- Messaging: Person-to-person text messages, group channels, GPS position sharing
Side-by-Side Comparison
| Feature | LoRaWAN | LoRa Mesh (MeshCore/Meshtastic) |

| Requires servers | Yes | No |
| Works off-grid | No | Yes |
| Node-to-node relay | No (an optional single-hop Relay extension exists, rarely deployed) | Yes |
| Primary use case | IoT sensors | Off-grid communication |
| Message type | Sensor data to server | Person-to-person text/GPS |
| Managed by | LoRa Alliance | Open-source communities |
| License required? | No (ISM band) | No (ISM band) |
What This Wiki Covers
This wiki covers LoRa mesh networking using MeshCore and Meshtastic. LoRaWAN is a separate topic entirely and is not covered here. If you are reading about "The Things Network," "Chirpstack," or "LoRa gateways," you are reading about LoRaWAN - a different technology from what this wiki describes.
When someone says they have a "LoRa device" that works with MeshCore or Meshtastic, they mean a device that uses LoRa radio with peer-to-peer mesh firmware - not a LoRaWAN end node.
