摘　　要：从电波传播的统计特点出发,针对目前我国GSM-R移动通信场强测试的采样间距进行了分析,在既有GSM-R线路上对国外应用的不同采样间距进行了对比测试,认为GSM-R移动通信系统的场强测试采样间距在小于Lee氏定律的情况下都是可以满足要求的。This paper analyzed the sampling interval of field strength test for GSM-R network in China in terms of the statistical characteristics of radio field coverage. Through comparative testing of different sampling intervals currently applied abroad on our existing GSM-R network, it was concluded that all less than the Lee-law sampling intervals of field strength test can satisfy the requirements.
