The fifth-generation(5G) mobile communication technology,as the next generation wireless mo-bile communication technology following the 4G communication,is now intensively researched and devel-oped ,thus to meet the rapid popularization of intelligent terminals and the fast development of mobile inter-net,and furthermore,to meet the information requirement of human society after 2020. The basic concep-tion,application prospects and performance of 5G are described firstly in this paper. Then, the key tech-nologies of 5G are illustrated emphatically, such as high frequency transmission, multi-antenna transmis-sion, point-to-point communication and dense networks. Finally, the challenges faced in the development of 5G are discussed in detail.
