摘要
对地面无线通信信号覆盖地铁进行了分析 ,提出了相关应吸取的经验和可以采取的方式。在地铁站厅、站台 ,采用天线列阵覆盖即可满足要求。而在隧道区间 ,特别是长隧道区间 ,用泄漏同轴电缆辐射覆盖较优。
With an analysis of how the ground wireliss signal covers metro and some experiences gained from practice, the author argues that a combined aerial installed in the station and platform shall satisfy this demand. But in tunnels, especially in long tunnels, it will be better to use leaking coaxial cable.
