| Abstract: | It constructs an evaluation system of the NB-Io T network and demand satisfaction. This system is based on the A-GPS MR data of 4G coverage area and simulation prediction of no coverage area. Considering the coverage difference factor of network format,coverage difference factor of different typical scenarios and coverage difference factor of different carrying frequencies,it forms a 20×20 m,iteratively updated underlying NB-IoT network coverage database. The minimum investment algorithm is used to realize the evaluation of NB-IoT network and market satisfaction,as well as the evaluation of minimum startup scale,so as to maximize the network coverage and investment benefits,speed up 5G m MTC scenario application business promotion. |
