电网5G链路预算关键项分析

Key Elementary Analysis of 5G Network Link Budget for Power Grid

现有5G链路预算分析主要针对移动用户和大带宽业务,而电网的通信终端形态、业务特征、终端位置分布等均同传统的移动用户存在较大差异,因此无法直接套用。文章基于5G新空口关键技术原理及电网业务应用特点,对基站和终端的发射功率与载波配置、天线设备、解调门限和接收机灵敏度、衰落余量、穿透损耗等链路预算关键项对基站有效覆盖半径的影响进行分析,并结合典型传播模型给出电网5G无线网络覆盖规划站间距建议。结果表明:分析结果更贴合电网业务的需求,可为电网5G覆盖规划提供更好参考。

Current link budget analysis of 5G network normally focuses on seamless area coverage for eMBB services of mobile users,which is not suitable for communication network planning of power grid due to different terminal types,service features and geological distribution of terminals.Based on the theory of 5G new radio key technologies and features of power grid service applications,key parameters which have vital influence on cell effective coverage radius such as transmission power of base station and terminal and carrier bandwidth,massive MIMO antenna configuration,receiver sensitivity and related demodulation threshold,fading margin and penetration loss are analyzed in this paper,advices of inter base station distance is given according to typical propagation model and suitable for power grid service so as to provide a reference for 5G network coverage planning of power grid.
