针对高速铁路无线通信系统数据交换速度缓慢的问题，给出一种可用于实际的无线WiFi通信系统。该系统以智能天线和无线收发设备为基础，通过分割移动IP在链路层(L2HO)及网络层(L3HO)切换的时间点，从而避免传统无线通信在切换时间点重合时所出现的通信中断问题。由于采用WiFi网络连接，故能提供相对于传统移动网络更为流畅的用户体验效果，可较好的满足用户日益增长的网络带宽需求。

[Abstract]The traditional high-speed railway communication systems met a lowly data exchange problem, this paper proposed a WiFi based wireless communication system. The system used smart antenna and the radio equipment, through separating the mobile IP handovers time in the data link layer (L2HO) and the network layer (L3HO) to avoid fatal communication disruption in the conventional wireless communication. This WiFi based network connection can provide better internet experience compared with traditional mobile network, also can met the growing demand for bandwidth of customers.
