摘要
为了解决移动通信信号分布不均匀的现象,采用调整基站天线参数和多基站天线联动的方式,对区域内通信信号覆盖情况进行研究。针对信号覆盖情况,通过车载无线测试设备反复对同一区域进行测试,对比天线参数调整前后信号地增强情况,确定最优化调整方案。测试结果表明:对于空旷无遮挡的区域,通过调整发射天线的方位角,可以改善该区域的无线信号分布质量;对于有遮挡而又不能直接增加信号强度的地区,通过对周围基站天线极化方向的联动调节,平衡区域内的信号差异,也可以有效的增强区域内的信号质量。该测试地开展可以为信号传输与分布的理论模拟提供一定的数据支持。
In order to solve the undistribution of mobile communication signal,the coverage was investigated by adjusting the parameters of a single base station antenna and multi station linkage.The drive test was taken to detect the difference before and after adjustment for the optimal scheme in a particular area.The results show that the signal can be balanced by adjusting the azimuth angle of the transmitting antenna in an open area.While in the covered area,signals can be reinforced by coordinating of multi antenna to enhance the quality of the signal instead of raising the power of the signal directly.The development of this test can provide some data support for the theoretical simulation of signal transmission and distribution.
