Research On The Planning And Implementation For High-Speed Railway In WCDMA Network

In recent years the rapid development of China’s high-speed railway construction business, a number of inter-city express railway and high-speed passenger dedicated line opening and operation of high-speed rail in the next few years will become the mainstream of China’s ground passenger. Went-Fu, the Fuzhou-Xiamen high-speed railway will be built north Changing River Delta economic blocks south of the Zhujiang River Delta in the developed areas, Fujian West Coast Economic Zone with convenient traffic conditions, will fundamentally solve the southeast coast of China Railway "bottleneck constrained problems, will attract a large number of high-end passenger traffic, the customer base of high-speed rail is a relatively high-income population-based, such as business travel or high-speed rail tourism, diverse high-speed rail passenger demand for communication services, voice services, data services addition to the video phone service and high-speed data services demand will be strong. Therefore, Went-Fu, the Fuzhou-Xiamen railway network coverage in respect of Unicom the company’s brand image. Went-Fu railway complex geological conditions, accounting for78.84%of the total length of the line, bridge and tunnel, bridge and tunnel proportion of the country existing and construction of a railway. Complex geographical network coverage along the project a huge challenge and pressure.The authors for high-speed rail WCDMA radio coverage of the special scenes, such as high-speed train running, cross-coverage network of large body penetration loss, more bridges and tunnels, the line and the surrounding complex, at the train station across the urban area staggered coverage areas, and public and private networks, regional span large and complex terrain, resulting in a variety of difficulty in-depth study, the specific analysis of the causes of these problems and find solutions; private network networking solutions proposed WCDMA coverage overlapping coverage area of the distance calculation, and the corresponding link budget process to solve the problems encountered WCDMA radio coverage of high-speed rail.
