| Abstract: | With the large-scale construction of urban rail high-speed lines (above 120 km/h), the traditional WLAN technology has difficulties in meet the requirements of high-speed switching and high-bandwidth wireless network for high-speed line vehicles. By analyzing the characteristics of the TD-WiFi technology, system scheme, operational test data, and experimental test data of authoritative organizations, combined with the innovative application on the Wuhan Metro Line 11, a networking solution based on TD-WiFi technology is proposed for high-speed line vehicle wireless network. The solution provides an important technical reference for the construction of lines above 160 km/h. |
