摘要
2014年是国内4G真正意义上实现商用的元年,后4G时代的通信技术被命名为5G.相对于4G,5G在传输速率、用户峰值速率、传输时延、连接设备密度、流量密度、移动性等方面均有较大提高.目前被关注的5G关键技术主要包括了超密集异构网络部署、大规模MIMO技术、毫米波的使用以及新的无线接入技术等.5G移动通信系统的定义目前仍然不明确,但是5G必然成为未来移动通信领域的主导技术.
As for communication society in China,the year of 2014 stands for the first commercial year.The technology of post-4G age is called 5G. Compared to 4G in terms of the user peak rate,transmission delay,density of the connected devices,traffic density and the mobility,5G has a significant improvement.What is highly concerned about 5G at present mainly includes ultra dense network,large scale MIMO,new technology of wireless access,and new frequency bands. Though 5G is not clearly defined now,it is bound to play a dominant role in the coming mobile communication.
