The Tangshan City's WCDMA Wireless Networkplanning And Optimization

With the WCDMA network technology increasingly mature, the improvement of terminal performance, the apid growth of high-speed data business, streaming media,video phone and other new business are being accepted by consumers.The quantity of Chinese 3G users and the income of Chinese 3G business present the trend of accelerated growth。Mobile communication network is a dynamic network,in the actual cases tend to emerge many new problems,so it requires operators completing the plan and optimize work for the network,making the network run in the best state,thereby let customers satisfy.And how to conduct the 3G network planning and optimization, called mobile operators major problem.This paper give the evolution process of mobile communication and WCDMA technical features a detailed introduction, and relying on the tangshan CDMA network, give the BS detailed address with software.At the same time WCDMA optimization is described in detail from engineering point of view,and carry on the optimization practice for tangshan WCDMA network, on the whole reach the optimization goal. The main contents include the following respects:Firstly, basic principle of WCDMA system, the key technology and principle explanation involved in WCDMA planning and optimization process;Secondly, combined with the actual situation of tangshan division, give the WCDMA network covering and capacity design and analyse the wireless transmission model, give the detailed map for BS address;Thirdly, Tangshan WCDMA network optimization process, such as material, equipment, working procedure, the process of analysing, etc; Fourthly, analysing and solving methods for the common problem in the implementation of WCDMA network optimization;Finally, combining tangshan specific circumstances solve the actual case in the network optimization by analysing,and summary the optimization experiences.
