MapInfo在CMMB路测分析中的应用研究

摘要

通过对中国移动多媒体广播(CMMB)路测系统和路测数据的简单分析,提出了一种CMMB无线网络分析的方法.在该方法中,首先将测试得到的大量CSV格式数据转化为Excel格式,然后通过MapInfo软件、平面地图和卫星地图制作分析数据用的电子地图,通过Maplnfo软件分析路测的数据,在实际分析中进行了应用,最后给出了无锡某区域CMMB无线网络测试分析的实例,为该区域CMMB网络的优化提供了可靠依据.从应用中可以看到,该方法不仅节约网络测试分析的成本,还能很好的得到CMMB网络优化的关键参数.%Through the analysis on the road test system and road test data of China Mobile Multimedia Broadcasting(CMMB), a method of analyzing the CM MB wireless network is proposed. Firstly, a large number of test data in the CSV format is converted to Excel format. Secondly, the electronic map used to analyze data is made by Map Info software, planar maps and satellite maps, and the road test data is analyzed by MapInfo software. Finally, an example of test and analysis on CMMB wireless network in some area in Wuxi is given, which provides a reliable basis for network optimization in this area. The method can not only save the cost of test and analysis on wireless network, but also get the key parameters of network optimization in CMMB.
