北京联通建设大厦WCDMA室内分布系统的研究与实施
摘 要
WCDMA是3G中最成熟,最被重视,也是开通网络最多的技术标准。随着WCDMA网络技术的日益成熟,终端性能的改进和提高,终端价格的日趋合理,数据业务需求的快速增长,全球WCDMA网络迈入了一个良性发展的阶段,用户数量和收入都呈现快速增长的趋势。随着移动通信网络的发展,室内覆盖是实现无线覆盖、优化网络容量分布和基站配置、增加话务收入、提高用户满意度的一个重要手段
从2009年开始,中国联通也大规模的进行WCDMA网络建设,为了带给用户更好的服务体验,有利于激发宽带市场的潜在需求。北京联通的新增网络采取先宏站、后微站的建设策略,在保证覆盖的前提下,逐步实现重点楼宇的深度优化。
本论文结合WCDMA的室内分布系统的特点,结合北京联通三区WCDMA的网络建设实际项目,通过介绍室内分布系统的有关知识。结合实际案例的应用将室内分布建设进行一定分析,对室内分布系统的设计标准和规划设计的有关知识,无线网络的建设以及系统建成后的测试和优化,进行了系统的研究。

The Design and Construction of WCDMA Indoor Distilbution System
ABSTRACT
With the increasingly mature WCDMA network technology, and improve the performance of disruption, the price is reasonable, the interruption of rapid growth data business needs, global WCDMA network entered a benign development stage, the number of users, and both the fast growth the tendency. Along with the development of mobile communication network, indoor coverage in wireless coverage, optimize network capacity distribution and station configuration, increase traffic income, improve customer satisfaction, one of the important means
At present,the domestic and international operators are set Off a building and the promotion of 3G to a climax.According to the experience of advanced foreignoperator,3G network construction focuses on indoor coverage,and built a goodindoor performance.the distribution system is a key to the success of 3G construction.
WCDMA is the 3G the most mature and the most attention.is the 1argest open network of technical standards.In this Paper'with the construction of ChinaUnicom WCDMA for WCDMA indoor distilbution system planning,design,construction and optimization of the entire process was comprehensive and systematic study.
In this Paper’first the general knowledge and characteristics of WCDMA mad
