WCDMA Indoor Distributed System Design And Realize

In2009,3G network construction is China’s first year. China Mobile, China Telecom and China Unicom3G network-building three carriers have invested heavily. WCDMA is one of the global standard33G and most mature industry chain, business application-rich, developing maximum number of users, opening the network up to technical standards.Along with the increasing maturity of the WCDMA network technology, and terminals to improve and enhance the performance of the Terminal prices become more reasonable, rapid growth in the demand for data services, global WCDMA network has entered a stage of healthy development, and rapid income growth in number of users. Especially as represented by the iPhone’s Smartphone promotion and universal, also the WCDMA technology thoroughly, has attracted a large number of high-end users to network, facilitate the development of the WCDMA business. Indoor coverage as an important part of the construction of the mobile Web, is covered for wireless base station configuration and distribution, optimizing network capacity, increase traffic revenues, an important means of improving user satisfaction, for the operators to improve the quality of mobile networks, improving service quality and brand are of vital importance.This paper begins with a brief introduction to WCDMA and related concepts, principles and techniques of indoor distribution system characteristics, elaborated on the necessity and urgency of the construction of indoor coverage, as well as the composition of indoor distribution system and the current difficulties encountered. Followed by a detailed study of indoor distribution system planning and design principles, objectives, design principles, construction processes, and selected, highlights the different sizes of indoor distribution system design, this is of great guiding significance in the actual design. Design, antenna design, and pilot traffic Prediction algorithm, link budgets, an in-depth study and detailed. Finally using this theoretical knowledge, to design a building of indoor distribution system, and a variety of technical indicators after the completion of the test.
