摘　　要：地铁是大城市主要公共交通工具之一,5G覆盖需求迫切。提出一种优化频段组合的泄漏电缆覆盖方案,在保证网络覆盖的基础上,不但可大幅降低3家运营商5G信号接入带来的互调干扰,而且可显著降低建设成本;此外提出一种泄漏电缆斜射覆盖的方案,可实现已运营地铁隧道的5G覆盖。2种方案均在广东地铁得到应用,效果良好。Subway is one of the major public transportations in big cities,and 5 G coverage is in urgent demand. An optimized leakage cable coverage scheme is proposed. On the basis of acceptable network coverage,this scheme can not only significantly reduce the intermodulation interference caused by 5 G signal of three operators,but also effectivity reduce the construction cost. In addition,it proposes a leakage cable oblique incidence coverage scheme,which can meet the need of 5 G coverage of the subway tunnel in operation. Both schemes have been applied in Guangdong subway with good results.
