摘要
提出了利用现有移动通信系统的功能,综合建立山区公路移动通信网的方案,分析了山区公路基站选址、天线应用与无线信号场强衰耗的关系,计算了山区公路中不同环境下移动通信电波传播的场强衰耗,对解决山区公路移动通信网建设与投资的关系进行了分析,给出了实现山区公路移动通信系统的方案。
Through the discussion on the location for base station, antenna application, and signal weakening, the calculation for the loss of the electromagnetic wave in the mountainous highway region was presented, the necessity and general idea of mountainous highway communication system construction by combining the advantages of several mobile communication systems were put forward. Based on the relationship between network construction and investment, the general concerns in the course of setting up the mobile communication system in mountainous highway region was analyzed, a workable solutions was developed.
