Link WAN forwards data to the Alibaba Cloud IoT Platform or a self-built cloud service.
Data is exported to the IoT Platform console using internal interfaces. Link WAN node information is automatically mapped to devices in IoT Platform.
Data is exported to a self-built cloud using Message Queue (MQ). You can subscribe to and consume data over MQTT.
Methods
We recommend different operation methods based on the user type.
If you are a developer new to networking, you can connect LoRaWAN devices from the Alibaba Cloud IoT Platform console. For more information, see Data ingestion to IoT Platform - 1-to-1.
NoteNode group 1-to-1 sync: This method synchronizes Link WAN node groups with the product and device list in the Alibaba Cloud IoT Platform.
The following figure shows the device ingestion flow in the IoT Platform console.
To aggregate data, you can configure node groups in Link WAN. This combines the data streams from these groups into a single product. For more information, see Data ingestion to IoT Platform - N-to-1.
NoteNode group N:1 mapping: This method maps multiple Link WAN node groups to the product and device list in the Alibaba Cloud IoT Platform and to topics in MQ.
N:1 mapping of node groups to a product and device list in IoT Platform
N:1 mapping of node groups to an MQ topic
NoteWhen using N:1 aggregation to an MQ topic, data is forwarded to a self-built cloud service.
