The Beijing-shanghai High-speed Rail In Cangzhou WCDMA Wireless Network Optimization

With the business operation of the Beijing-Shanghai high-speed rail,A newrequirements for WCDMA network optimization witch cover rail on the desk.High-speed rail trains run fast, and a high degree of compartments sealed. Thewireless signal fading fast, accompanied by the Doppler effect produced by thehigh-speed mobile and high sealing bodywork for signal attenuation are required forhigh-speed rail WCDMA network optimization is different from the conventionaloptimization ideas and ways.References of the Zaozhuang segment of the Beijing-Shanghai high-speedrailway, Shanghai-Nanjing high-speed rail and the Wuhan-Guangzhou high-speed railWCDMA optimization experience, Combined with the network planning method，analysis of the base station layout, antenna set, wireless parameters for optimizing theimpact of the work, sorting out the principle of optimization of high-speed rail. Inaccordance with the present mesh condition analysis, basic information verification,network structure combing, problem identification and optimizing the processingoptimization process, combined Cangzhou actual circumstances were several roundsof optimization, testing, adjusting work, achieve and exceed the Unicom Group, forhigh-speed rail network of the indicators requirements. For the mobile terminalsfound in the test for the influence of the test results were related analysis. TheBeijing-Shanghai high-speed railway Cangzhou stable operation of WCDMA network.By the Cangzhou paragraph summary of the optimization, also provide experienceand data support for the upcoming Beijing Wu optimization of the Hebei section ofthe high-speed rail.
