摘要
随着3G移动通信技术的发展,无线网络规划及优化变得越来越重要。在WCDMA系统中,由于引入了不同的数据业务,加上WCDMA系统本身的特点使得WCDMA系统在规划时有许多不同于GSM系统的地方。文章主要介绍了WCDMA无线网络规划的关键点,包括小区呼吸效应、小区覆盖与容量相互依赖关系、导频功率分配等;说明了网络规划及其流程;最后简单介绍了WCDMA无线网络优化。
With the development of 3G mobile telecommulication technology, radio network planning and optimization is becoming increasingly important. The planning process of WCDMA radio network is different from that of GSM network due to the introduction of various data services in WCDMA system and the characteristics of the WCDMA itsetf. This paper emphasizes the key points of the WCDMA radio network planning including cell breathing, the relation between coverage and capacity, pilot power distribution. The network planning and its flow are explained. Finally, the WCDMA radio network optimization is discussed simply.
