Wireless communication based train control system to operate in LTE installation smooth shaded area by analyzing the communication and optimal installation location for the RU, antenna type, intensity, and spread it aims to analyze. Analysis by taking advantage of the Cell Planning and program analysis was performed cover, 2.6GHz LTE with different specifications and directional, isotropic antenna configurations were analyzed by classifying shaded area. Radio communication based train control system can enhance the headway and safety of train in the manner of using radio communications instead of the wayside equipment such as the track circuit installed in the track. we analyzed wireless environments of Daebul Line which was selected as the test section, and in this paper, we measured the performance of radio communication device to be applied to the radio communication network and selected a optimized location which has no shaded area.
