摘要
针对高速铁路的移动信号覆盖问题,从影响高速铁路WCDMA网络的车体穿透损耗、多普勒效应等因素进行分析,并结合武汉—广州客运专线高速铁路的工程实践,详述网络规划和组网方案,提出了网络覆盖解决方案.
The WCDMA mobile cellular network coverage of high-speed railways is analyzed,including the path loss of train body,Doppler effects,and so on. With the help of the practice in the Wuhan-Guang- zhou High Speed Railway project,a coverage approach and optimized network planning are discussed and proposed.
