| Abstract: | 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. |
