WCDMA是第三代移动通信系统的主要无线传输技术标准之一,与窄带CDMA相比,传输信号采用了宽带扩频技术。首先就WCDMA的接入网UTRAN结构进行分析,进而讨论了CDMA与GSM网络规划设计上的区别,并详细探讨了WCDMA无线网络规划,包括话务模型分析、链路预算分析和网络容量估计等。
WCDMA is the third generation of mobile communication system, one of the major wireless transmission technology standards, compared with narrowband CDMA, the transmission signal using broadband spread spectrum technology. First, we analyze the UTRAN structure of WCDMA access network, then discuss the difference between CDMA and GSM network planning and design, and discuss the WCDMA wireless network planning in detail, including traffic model analysis, link budget analysis and network capacity estimation.
