The Design And Optimization Considering Wireless Coverage For Umts900

The Ministry of industry and information technology on January7,2009to China Mobile,China Telecom, China Unicom respectively issued the licence,including the basic telecommunication business license and the third generation of mobile communication business licence is a3G license,China mobile access to China’s own intellectual property rights of the TD-SCDMA license, China Telecom was the CDMA20001icense, China Unicom WCDMA operating license.China telecom industry officially entered the era of the3G,construction and operation of three operators according to their sector3G network, competing independently.Three operators are in accordance with their respective plate construction and operation of3G network, the independent competition. Since commercial, China Unicorn’s WCDMA network,users have maintained stable growth.To further enhance the user perception, is imperative to expand network coverage.But China has a vast territory, facing huge amounts of money into improving the coverage of the, especially in Xinjiang one-sixth per cent of total national land area, improving of cost-effective network covers the problems to be solved urgently.This paper primarily for Xinjiang Unicom WCDMA network optimization design and initial implementation of UMTS900wireless coverage scheme, main working papers include:1,to research on UMTS900technology discussions, research on UMTS900technology features and functions.2, Discusses the various ways to network, combined with the network status, explore the deployment of UMTS900applicable scenarios.3,Design experimental implementation of UMTS900.4, Studies in the existing network through the GSM900M frequency compression,frequency planning and implementation of UMTS900network construction impact on network, confirm that the original frequency and can be deployed in the region between regional reserve protect, through geographic isolation to overcome interference problems between networks.5,Organizes research on UMTS900network analysis of tested after construction work,develop effective network optimization solutions. UMTS900networks test analysis, develop an effective network optimization solution.UTMS900experimental construction in the process of implementing wireless coverage, I have mainly involved in experimental cutting of access networks, testing, analysis and system maintenance.
