摘要
对圆心地网的重要性、更新改造的必要性以及场强覆盖进行研究,通过场强覆盖收测数据对比分析和收听评价分析,得出基于圆心地网敷设能够正向影响转播节目的无线网络覆盖,圆心地网敷设提高了无线网络的覆盖区域和场强值,提升了节目收听评价。
The importance of the center ground network, the necessity of renovation and field strength coverage were studied, and through the comparison and analysis of the field strength coverage received data and listening evaluation analysis, it was concluded that the laying of the center ground network can positively affect the wireless network coverage of the rebroadcast program. The laying of the center ground network improves the coverage area and field strength value of the wireless network, and improves the program listening evaluation.
