无线网络通信是先进的通讯技术，利用无线网络开展的信息化应用具有显著优势，在地震观测与测震台网建设中，选用无线网络通信，组网便捷，既能实现数据传输，也能节约成本。CDMA有多种组网方式，进行高效组网，要根据不同环境来规划。简述CDMA无线传输技术在乌江数字地震台网的应用，找出影响传输质量的原因。

With the development of the society and the application of the modern communication technology, the social informationization level has been greatly promoted. We can exchange messages whenever and wherever. The wireless has been one of the advantaged techniques in communication application. We apply the CDMA wireless communication in earthquake observation to transmit data rapidly and build network expediently according to the different conditions. Here we discuss the application in the digital seismic network in Wujiang drainage area.
