WCDMA Wireless Network Construction Planning And Engineering Optimization Of Yangquan Of China Unicom

With the issuance of 3G licenses, China Unicom and other operators, WCDMA technology in the global technology most widely used and most mature, the business end is the most abundant. Unicom need to use the advanced nature of the WCDMA, the difference operation in the mobile communications market place. But the current WCDMA network coverage, capacity can not meet the rapid development of the user. Unicom needs to be improved WCDMA network coverage, capacity and quality. This article is in this context, the the Yangquan Company 2010 WCDMA radio network planning and construction in order to provide users with high-quality 3G network.The authors are now employed in the the Yangquan Unicom network optimization center, as the province of technical experts, has long been engaged in the mobile network first-line maintenance and network optimization, to accumulate and master a large number of network planning and optimization of practical experience in this project, the organization and participate inthe needs analysis, building programs, guidance and participate in the completion of the optimization, the overall tracking control to optimize the effect. Summary of the monitoring resource optimization, performance indicators and data services TOP plot analytical processing, 2/3G interoperable optimized the application of the six scenes, by actual cases and data, able to deal with various problems have emerged in the network, and achieved good results.The thesis is divided into seven parts, introduces the research background and research, the first WCDMA network systems were introduced, and focused description of the WCDMA network to take four key technology for duplex technology, multiple accesstechnology, RAKE receiver, fast power control to do a detailed exposition. Secondly, the the Yangquan WCDMA radio network building needs a comprehensive analysis, from Yangquan geographical overview of the current network coverage to the current situation and existing problems, several aspects of the users and the development of business volume forecast, to finalize the planning ideas of the current project and scale. On this basis, the existing network from both the robustness and low cost of wireless network design and planning, perfect the current network coverage of planning programs. Network building network is put into use, the organization of the network optimization of the current project. Optimize the effect of the 2010 running of a network of wireless network construction engineering and engineering evaluation tests, papers not only from the assessment indicators of the entire network breakdown each of the test compared Yangquan the main city of the key business areas, Yuxian peace given field road test the effect of contrast, the current project can be seen by the large amount of test data and the tracking and detection coverage to achieve the desired effect. Network complaints have decreased significantly improved network quality. Finally, combined with the current engineering experience gained on the project summary, further outlook of future work.
