In LPWAN,NB-IoT and eMTC technologies have been widely used in remote wireless Internet of Things communications since their introduction.The key to their application design is to select a cost-effective NB-IoT/eMTC chip or module programming to implement protocols such as UDP/COAP/LwM2M/MQTT.When developing products,terminal devices containing NB-IoT/eMTC can access the software system,either through intermediate cloud service platforms such as OneNET,or through flexible structure analysis based on protocols such as COAP,to complete the reporting of collected data and the orderly distribution of control data. Distinguishing between different application scenarios and adopting different data transmission and low-power strategies can bring the excellent performance of NB-IoT/eMTC into play.
