The Application Prospect of 4G Communication Technology in Smart Grids

Abstract

At first, this paper analyzed the key technologies of the 4G communication system and the main advantages in comparison with the 3G communication system in communication rate, time-delay, spectral efficiency, etc. And then, it analyzed the smart power grids’ demand for communication technology and the limitations of traditional electric power communication. By Comparing with the traditional electric power communication, it demonstrated that the 4G communication system is suitable for smart power grids. At last, this paper prospected the application fields of the 4G communication system in the smart power grids, and also raised the issues and challenges that electric power enterprises will face.
