In this paper, the key technologies of 4G mobile communication are briefly discussed, the significance of 4G network communication is studied, the network structure of 4G and the key technologies of 4G are analyzed. Based on this, the advanced network of 4G technology in China is discussed Signal technology, and finally predict the future of 4G. The significance of the fourth generation of mobile communication Fourth generation mobile communication technology Even though we often mentioned 4G network technology is based on the previous 3G network technology, combined with WLAN technology, resulting in faster download speeds and higher quality Pictures, audio and video file transfer. At this stage we have developed the fourth generation of communication technology has many characteristics. In general, the first is to increase the speed of communication. 4G communication technology
