WCDMA Radio Network Planning For Jiuquan China Unicom Of Gansu Province

Aiming With the rapid development of mobile communication technology, types of mobile communication services enrich, the traditional and low-speed data services with voice-based second-generation terrestrial mobile communication system has been increasingly unable to meet people’s requirements, The world has entered a third-generation mobile communications research and some commercial operations. WCDMA system as the three major 3G standards is one of the most current standards of commercial networks, but also the highest standards of prospective users, A direct impact on the wireless network planning, network construction cost and operating performance of the network construction process in a very important part, so WCDMA radio network planning study has important practical significance. This article start to introduce to the 3G system, the basic concepts and the main parameters of WCDMA systems, technical characteristics, the network structure, and WCDMA radio network planning idea is illustrated, On this basis, summed up the characteristics of WCDMA radio network planning and processes, and the main elements of its network planning and analysis of key technologies to study the spread of WCDMA radio network planning model for correction, link budget, the base station capacity calculation, the base station interference and isolation requirements of several core issues, Then focused on analyzing the WCDMA network planning and optimization methods, including link budget, coverage and capacity planning, base station set up and station site surveys and so on, from the coverage and capacity of both studies, Then, take Jiuquan City, Gansu Province WCDMA radio network planning project as an example First of all pairs of Jiuquan City area user capacity of WCDMA networks were predicted and the combination of Jiuquan City area WCDMA network coverage and quality objectives and requirements of the Jiuquan City area carried out a detailed zoning. Then according to WCDMA radio network planning process with a preliminary calculation of the actual situation of Jiuquan out of Jiuquan for wireless network planning results and the simulation results of the planning has been adjusted. Finally gives the Jiuquan city of WCDMA radio network planning of the base station settings, capacity allocation, RNC settings, transmission requirements, etc. In short, the papers described in full WCDMA wireless technology based on WCDMA radio network planning of the various technical aspects of the research, analysis and discussion, and in Jiuquan City, WCDMA radio network planning, project background, a systematic summary of WCDMA radio network planning principles and methods, with a view to the future of Jiuquan City, WCDMA wireless network in the construction of the network planning can make a good program to create the best network operational efficiency. Finally we summarize this paper and show the developing trend and give an object for further analysis.
