This paper carries out the analysis of potential influences of high-speed mobile on TD-SCDMA network organization

including the doppler frequency shift

smart antenna

power control and synchronization

network switching and re-elected

and train penetration loss. In conjunction with the frequency shift correc- tion algorithm

base stations layout principles are given to meet the quality of coverage and the require- ments of switching. At the same time the two networking methods of private and public network are analyzed and compared.
