GSM-R Network Coverage Scheme for Crossing and Shared Sections of Xi'an-Yan'an HSR
In light of the crossing and shared sections between Xi'an-Yan'an HSR and the existing Conventional Baotou-Xi'an Railway and Zhengzhou-Xi'an HSR,GSM-R network coverage planning is required in both sections.Firstly,according to the design standard of Xi'an-Yan'an HSR,its GSM-R wireless subsystem network adopts a single-network interleaved coverage mode.This paper carries out the demonstration and analysis mainly from the aspects of coverage mode,level requirements and base station capacity calculation.According to different railway train control levels,corresponding network coverage schemes are formulated for the crossing and shared sections of Yan'an Station and Zhengzhou-Xi'an HSR.The actual test is carried out on the co-cell base station.Under the design speed of 350 km/h,the minimum available receiving level of RF signal at the antenna input end of the receiver meets the requirement that the minimum available receiving level is not less than-92 dBm under a 95％time and place probability,which can provide a reference for GSM-R network design scheme in similar complex sections.
