What types of devices does the LoRaWAN protocol support

The LoRaWAN protocol supports three main types of devices (i.e. terminal categories), namely Class A, Class B and Class C. Each category is suitable for different application scenarios, and the main difference lies in how they communicate with the gateway and their ability to receive downlink data.

Three main types supported by LoRaWAN protocol

(1)Three main types supported by LoRaWAN protocol

Working method: After completing an uplink communication (i.e. sending data to the gateway), the Class A device will open two short receiving windows. This method ensures that the device can receive a response from the server, but the receiving window is only open briefly after sending data.

Features: This mode has the lowest power consumption and is very suitable for terminals that rely on battery power.

Applicable scenarios: Suitable for low-power, intermittent communication scenarios, such as environmental monitoring, remote meter reading, etc.

(2)Class B (regular reception)

Working method: Class B devices add the function of periodically opening receiving windows to the basic Class A mode. The device opens these receiving windows by receiving synchronization signals (beacons) from the gateway, so that the server can send data to the device within a predetermined time.

Features: Class B devices consume slightly more power than Class A devices, but have higher receiving flexibility.

 Applicable scenarios: Applicable to application scenarios with high latency requirements and the need to receive control information regularly, such as smart lighting, device control, etc.

(3)Class C (maximum reception)

Working method: The receiving window of Class C devices is almost always open, and the receiving window is only closed briefly when the device is sending uplink.

Features: This mode consumes the most power because the receiving window is almost always open, but it provides minimal latency and the server can send commands at any time.

Applicable scenarios: Suitable for applications that are not limited by power consumption and have high real-time requirements, such as industrial automation, real-time control, etc.

(4)Conclusion

Class A: Low power consumption, occasional reception, suitable for battery-powered, intermittent communication.

Class B: Periodic reception, suitable for applications with certain requirements for latency.

Class C: Real-time reception, suitable for devices with high real-time requirements, but with high power consumption.

In a LoRaWAN network, different types of devices can coexist, so you can choose the appropriate device type according to different application requirements.
