Abstract: This paper focused on the environmental characteristics of High-Speed Railway (HSR) and its influence on 3rd Generation (3G) mobile communication networks. Firstly, the technical characteristics of three major 3G communication standards in China were analyzed, especially the two key issues in the construction of HSR communication system: wireless coverage and fast handoff. Then the body loss of serials of HSR, the minimum switching area and the optimization deployment strategies of 3G communication technologies in China were summarized. Lastly, the tendency of HSR's wireless communication technologies was prospected and it was found that the Long Term Evolution (LTE) technologies could provide the technical feasibility for the broadband application services of HSR. Hence, it is suggested that we should strengthen the research for wireless transmission performance optimization of TD-LTE in HSR environment.

Key words: high-speed railway, 3rd Generation (3G) mobile communication, wireless coverage, handoff, Time Division Long Term Evolution (TD-LTE)
