    The advantage of LoRaWAN is that it can cover a wide geographical area, while supporting the connection of a large number of devices, low power consumption, high capacity, low cost, flexibility and scalability, no carrier charges, etc., for smart cities, industrial automation, environmental monitoring, smart agriculture and other scenarios is very ideal choice. .pusr.com - 6 -...

  • Page 7: Lorawan Apology

    End devices in a LoRaWAN network come in three classes: Class A, Class B and Class C. While end devices can always send uplinks at will, the device’s class determines when it can receive downlinks. The class also determines a device’s energy efficiency. The more energy efficient a device, the longer the battery life. .pusr.com - 7 -...

  • Page 8: Parameters Introduction

    End devices in Class C mode are used when extremely low power consumption is not an issue and latency needs to be minimized. The server-side application determines that it is managing class C devices during the join procedure. Note: USR-DR206 supports class C mode only for now. 3. Parameters introduction 3.1.
