[Abstract] In this paper, according to the technical features, networking methods, and potential application scenarios, we point out the key problems of narrowband Internet of things (NB-IoT) , such as the data security and transmission reliablity for NB-IoT, the evolution of the NB-IoT to wideband IoT(WB-IoT), and the coexistence of low, middle and high data rates for IoT devices. The multirate devices are proposed as the direction of NB-IoT research in the next stage.
