Td-scdma Wireless Network Planning And Optimization Of Yan'an

With the development of TD-SCDMA mobile communication technology, and a variety of key technologies successfully resolved,and the commercialization of TD-SCDMA system, terminals, base stations and wireless controller and so on, network planning and optimization is increasingly important. For the TD-SCDMA network operators in future, they are paying more attention to cost-effectively building a TD-SCDMA network and to ensuring network construction high cost. Generally speaking,the purpose of network planning is, with the support of a variety of multimedia services and certain Qos conditions,to obtain good network capacity and to meet certain requirements of wireless coverage, and by adjusting the capacity, coverage, quality and balance between relationship to provide the best link service. The main goal of network optimization is to improve the overall performance of the network. One is to provide more excellent services to users in present system, The other is to increase the system capacity in order to accommodate more users in future system. Thus network optimization should be to attached importance, and become increasingly important for the network operation and maintenance, network planning and construction.In this thesis, the main topic is about TD-SCDMA network planning concept, the basic principle and the basic processes such as network planning. Based on the analysis of theory of knowledge in the natural environment and China Mobile in Yan'an development forceast, we take part in Yan'an TD-SCDMA wireless network planning and specific implementation and the early TD-SCDMA wireless network engineering optimization. Some questions in TD tests are found, and corresponding optimal adjustment programs are given. Through reasonable network planning and optimization, the TD-SCDMA network in Yan'an is cost-effective constructed to meet the demand of future customers.
