| Abstract: | Against the backdrop of the need for rail-land wireless communication network regarding the current rail transit operation and security, this thesis put the technical solutions of WLAN and TD-LTE into comparison and the analyses showed that the latter is more suitable for rail transit. By combining a real project, the 1st phase of Line One for Zhengzhou rail transit, the thesis has verified that TD-LTE can achieve massive broad-band transit and technical multi-tasking under high-speed mobility, thus the elimination of rail-land communication bottleneck in rail transit and the realization of operation. |
