摘要
随着城轨高速线路(120 km/h以上)的规模化建设,传统的WLAN技术难以满足高速线路车地无线网络高速切换、大带宽应用要求。通过对TD-WiFi技术特点、系统方案、运营测试数据与权威机构实验测试数据等内容进行分析,结合武汉地铁11号线的创新应用,提出基于TD-WiFi技术的高速线路车地无线网络组网解决方案,为160 km/h以上线路建设提供重要技术参考。
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.
