However, the penetration force of the high-frequency signals is poor, and in a region where the buildings are relatively dense or a region where the base stations are not constructed by people, if the number of the base stations is insufficient, the signals have great problems. In addition, a relatively fixed base station is generally required, mobility is poor, and when a 5G signal is weak and cannot be accessed, user data cannot be transmitted, so that disconnection is caused. Current 5G communication technologies face several challenges, including in particular: (1) The number of base stations and coverage limit are that the construction cost of the 5G base station is high, and the coverage range is smaller than that of the 4G base station due to the frequency band characteristic.
