摘要
重载铁路双洞单线长大隧道的场强覆盖是GSM-R覆盖领域的难点,通过对比分析提出此种隧道类型GSM-R覆盖的解决方案,解决列车沿上下行不同线路驶入双洞单线隧道可能出现的掉话问题,并给出洞内逻辑基站洞外放置原则。
There are lots of difficulties in GSM-R covers technology of the long separated tunnels. This paper gives a cover solution of this type of tunnels in GSM-R technology, and solves probable problem of dropped calls, especially when train gets into tunnel on different track direction. And it＇s illustrated a principle of setting up base stations out of this type of tunnels.
