- Abstract
With the rapid development of China's high-speed railway network, the relocation of existing base stations and repeaters caused by new line construction is inevitable. The relocation of existing GSM-R equipment will often bring changes in wireless network coverage, especially in some complex sections such as cross and parallel lines, and the network problems are likely to occur to cause CTCS-3 wireless connection timeout. This paper expounds the multipath interference problems and subsequent treatment process after the relocation of base stations and repeaters caused by the connection of Hangzhou-Wenzhou high-speed railway with Yiwu station of Hangzhou-Changsha high-speed railway, and summarizes the troubleshooting and treatment methods of repeater multipath interference, so as to help reduce the impact of the subsequent new line construction on the existing GSM-R network.
