The topology and deployment scheme of the LoRaWAN network have a significant impact on its performance and coverage. The following is a detailed introduction to the LoRaWAN network topology and deployment:
1. LoRaWAN network topology
The LoRaWAN network mainly adopts a star topology. The specific topology includes the following components:
1.1 End Devices
Features: These devices communicate with one or more gateways via the LoRa wireless link. The end device can be a sensor, actuator, etc.
Communication mode: The communication between the end device and the gateway is single-hop, that is, data is sent directly to the gateway via the wireless link.
1.2 Gateways
Features: The gateway receives the LoRa signal sent by the end device and forwards the data to the network server via the IP network.
Multi-gateway reception: The data sent by the same end device can be received by multiple gateways, which increases the redundancy and reliability of the network.
1.3 Network Server
Function: Responsible for data deduplication, device management, data routing, security control, etc.
Redundant processing: The network server will process redundant copies of the same data packet to ensure data integrity and reliability.
1.4 Application Server
Function: Receive data forwarded by the network server and execute specific application logic, such as data analysis, processing and storage.
