本文根据无线网络忧化的专业知识和实际经验着重介绍了无线网络优化中对空中接口的优化工作，说明了该部分的优化是通过对空中接口进行测试和数据采集，然后分析无线网络状况，再进行优化，不断改进，最终达到优化目的。在交流优化体会的同时，介绍一个优秀的网络优化工具：ＵｍＳｔａｒ产品，并给出了几个使用ＵｍＳｔａｒ进行无线网络优化的困片加以说明。 This article focuses on the optimization of air interface in wireless network optimization based on the professional knowledge and practical experience of wireless network mitigation. It shows that the optimization of this part is through testing and data acquisition of air interface, and then analyzing the status of wireless network. Then Optimize, improve continuously, and finally achieve the purpose of optimization. While exchanging and optimizing the experience, introduce a good network optimization tool: UmStar products, and give out a few to use UmStar to carry on the radio network optimization to prove.
