Research On Key Technologies Andapplications Of NB-IoT In Xishuangbanna Branch Of China Telecom

In recent years,with the rapid development of computer Internet technology,people have more and more demands on the Internet of things.IoT business involves various aspects,especially the technical principles and business application development of iot,which are the key to the future development of operators.As one of the three major operators in China,China telecom attaches great importance to the development of the Internet of things,and nb-iot technology happens to be one of the most important and widely used IoT technologies.As the application of the Internet of Things technology is in the transition from the 4G era to the 5G era,it is of landmark significance.As 4G enters the commercial scale stage,the fifth generation mobile communication oriented towards 2020 and the future has become a global research and development hotspot,and the Internet of things business is the main application scenario in the future 5G era.In this thesis,the key technologies of narrow-band Internet of Things(NB-IoT)service are analyzed and studied,and the service of NB-IoT is realized by using the access point name(APN)dedicated line form of the Internet of Things.Combining with my work on the NB-IoT project in the network Department of Xishuangbanna Branch of China Telecom Co.,Ltd.,and aiming at the current situation of NB-IoT,this thesis studies the business process of NB-IoT,completes the face recognition project of Banna Branch of China Southern Power Grid,which is applied in many scenarios,such as indoor access control,intelligent business hall and so on.
