The Siping City's WCDMA Wireless Network Planning And Simulation

As the 3G license issuance, various carriers have in the original 2G network based on 3G network, active in a variety of new business applications. How was the development of 3G, network quality is the most important, without good support network quality to do, no matter how good business can not achieve or can not be better achieved. Early network planning largely determine the structure of the network, on network investment, and quality play a decisive role in the future network development.3G network planning, including the core network planning and wireless network planning, including planning for wireless networks to provide high cost, improve service and first-class network quality plays an important position. For the WCDMA system this complex, many factors and mutual coupling, WCDMA radio network planning is comprehensive and diversity, the theoretical capacity of the error is larger cover predictions. The use of system simulation, simulation systems are able to work through the process, are based on model-based analysis of system capacity coverage to rational design of network scale and the scale of investment.This article describes the WCDMA radio network planning of the research background and technical status; Analysis of the WCDMA network structure and technical characteristics, and WCDMA radio network planning of the content, features and analysis processes, the need for the system simulation and simulation processes and tools are introduced; Overview of the city of Siping and the urban environment is described, the analysis shows the regional division of the city, given Siping WCDMA wireless network coverage in the preliminary planning design and capacity design; Determined by analysis of wireless propagation model, and gives the detailed planning of distribution planning site; Wireless network planning system simulation results to analyze the feasibility and make amendments, mainly pilot coverage, communication quality, pilot pollution, cell load, cell capacity, outdoor mobile phone transmit power, switch performance, network quality of simulation results analysis; Finally, the paper summarized the research results, discuss the WCDMA radio network planning of further research space, and the 3G development.In this paper, the subject of today's communications industry has a positive meaning and the construction of WCDMA networks has practical significance. With commercial WCDMA network, network planning and optimization is a long-term problem.
