| Along with the wide spread of3G network business in China, as well as the increasing development of social economy, there will be more and more chances to use communication devices in high-speed mobility environment for purpose of voice and data services. Therefore, it is of great importance to conduct research on communication network construction planning in high-speed environment. By special planning and construction on wireless network coverage along high-speed railways, it is highly desired to enhance the network coverage level on high-speed trains, improve the quality of mobile communication, and meet the demand of smooth communication.On the other hand, the majority of high-speed rail passengers are business people, who have high demands and quality requirements of voice and data services. However, due to their special manufacturing materials and good encapsulation, the bullet trains and high-speed trains may cause a significant attenuation of wireless signal. When a high-speed train reaches a speed of300km/h, problems such as Doppler Effect and frequent switch start to emerge.As a result, the accurate coverage of high-speed railways is very crucial for CDMA network, which not only provides high-end customers with network supports, especially in high-speed data services, but also helps promote China Telecommunication’s brand competitiveness.In this thesis the author has analyzed the difficulties in network coverage along high-speed railways, and compared respective advantages and disadvantages of various network coverage plans. The purpose of this thesis is to explore an effective coverage plan for Huaian Telecom Corporation by integrating the practical situations of Huaian telecommunication. By the proposed coverage plan, it will be possible to establish a stable high-speed communication network similar to regular network for steady communication, to provide reliable communication, and to enhance the quality of CDMA network by Huaian Telecom Corporation. |
