How is LoRaWAN network architecture structured?

The LoRaWAN network architecture and its working mode are the key to achieving these characteristics. This article will analyze the network architecture and three main working modes of LoRaWAN in detail.

The LoRaWAN network is mainly composed of four parts: end device, gateway, network server and application server. They each have different functions and roles and together build the entire LoRaWAN network.

End Device:

The end device is a sensor node or actuator in the LoRaWAN network, usually referred to as a node. These nodes can be a variety of sensors or actuators, such as environmental monitoring sensors, smart metering devices, etc. The end device communicates with the gateway through LoRa wireless technology and is responsible for collecting data and sending it to the gateway.

Gateway:

The gateway is a bridge connecting the end device and the network server. It is responsible for receiving the data sent by the end device and forwarding it to the network server.

The gateway is usually installed at a high place to provide the best coverage. Each gateway can cover a range of several kilometers, which enables LoRaWAN to achieve wide-area coverage.

Network Server:

The network server is responsible for managing the terminal devices and gateways in the entire LoRaWAN network. It processes the received data and forwards the data to the application server or other network servers as needed.

The network server is also responsible for functions such as authentication, encryption and decryption, data deduplication and network management of the terminal device.
