摘要
在LPWAN中,NB-IoT和eMTC技术一推出便在远程无线物联网通信中获得了广泛应用,其应用设计的关键是选择好性价比高的NB-IoT/eMTC芯片或模块编程实现UDP/COAP/LwM2M/MQTT等协议。开发产品时,含有NB-IoT/eMTC的终端设备接入软件系统,可以通过OneNET等中间云服务平台,也可以基于COAP等协议直接进行灵活构造解析,完成采集数据的上报和控制数据的有序下发。区分不同应用场景采取不同的数据收发和低功耗策略,可以发挥NB-IoT/eMTC的优良性能。
Abstract
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.
