Abstract

With the development of the communications market and the progress of communication technology, LTE which as gradually become standard for mobile broadband network is the standard of 3 GPP R8. With the development of the Chinese market, LTE is bound to be widely used in China. This article mainly introduces simple knowledge related to LTE, let the reader a better understanding of this new type of mobile broadband wireless access technology. At the same time some analysis and research on some related problems, seek LTE larger development space, make its application more widely.

This paper firstly introduces the characteristics of LTE technology and some key technology.Then it introduces the process of the LTE evolution. Through the analysis of LTE and HSPA+ technology comparison, this paper expounds the performance and advantages of the technology of LTE. And, looking forward to the 4G LTE - A evolution direction on this basis
