摘要
基于窄带物联网(NB-IoT)的技术特点、组网方法及潜在应用场景,指出了其发展过程中面临的关键问题,包括NB-IoT的数据安全与传输可靠性,NB-IoT向宽带物联网(WB-IoT)演进的问题,以及物联网设备连接需求的低、中、高速率共存的问题。认为多速率物联网设备的研究将是下一阶段NB-IoT发展的重点方向。
In this paper,according to the technical features,networking methods,and potential application scenarios,we point out the key problems of narrowbandInternet of things(NB-IoT),such as the data security and transmission reliablity forNB-IoT,the evolution of the NB-IoT to wideband IoT(WB-IoT),and the coexistenceof low,middle and high data rates for IoT devices.The multirate devices areproposed as the direction of NB-IoT research in the next stage.
