根据西宁站铁路枢纽各线路走向、线路等级、地形地貌、覆盖和性能指标,通过该地区基站容量计算、切换控制、频率规划,进行基站覆盖仿真、同频干扰仿真、临频干扰仿真,以仿真为基础对西宁站铁路枢纽地区GSM-R无线网络规划研究。对GSM-R无线网规划进一步分析,GSM-R系统受到窄带频率资源和体制缺陷的制约,不能满足铁路宽带移动通信需求,提出研究发展下一代铁路移动通信的迫切需求。
According to the line direction, line grade, topography, coverage and performance indexes of Xining Railway Station, base station coverage calculation, co-channel interference simulation and PIM interference simulation are carried out through base station capacity calculation, handoff control and frequency planning in this area. Based on GSM-R Wireless Network Planning in Xining Railway Station Area. The further analysis of GSM-R wireless network planning, GSM-R system is limited by narrowband frequency resources and system defects, can not meet the demand of railway broadband mobile communications, and put forward the urgent research and development of the next generation railway mobile communications.
