| China General Administration of Sports requests China Mobile Group to give the Mount Everest mountaineering way normalizing service, moreover, Beijing Olympic Organizing Committee will hold "Olympic flame cross Mount Everest" in Tibet in 2008 from April to June. On May 22 2007, the Chinese Mobile Group has been clearly taken "Olympic flame cross Mount Everest "as a turning point, solves the Mount Everest supreme headquarters to the Mount Everest prominent peak GSM network service cover normalizing problem. Our project group started the Mount Everest GSM cover engineering construction in June, 2007.In order to safeguard the Olympic flame to surmount Mount Everest smoothly,we must cover the whole mountaineering way and Mount Everest supreme headquarters with networks. The goal is to build some base station along the way, undertakes the Olympic flame to surmount Mount Everest's communication support. This engineering design mainly includes the wireless base station, the transmission, the power source, the solar energy platform and so on.This paper contains six chapters. The first chapter is the outline, mainly includes the design basis of this project, the project background and the implementation natural environment, mountaineering route, design scope and division of labor, total amount. The second chapter introduced the wireless network design plan, including the wireless network construction plan, the wireless network construction principle, the base station construction plan, the choice of the unit type and the target, the base station monitoring, the base station establish,the base station establish selecting location, the compatible battery and the battery radiation. The third chapter introduced the transmission network construction plan, the primary coverage includes: transmission solution way choice, Mount Everest supreme headquarters base station microwave transmission plan, 6500 meters battalion base station satellite transmission plan. The fourth chapter introduced the necessary power source design, including: 5200 meters and 5800 meters cocurrent power supply system and the equipment disposition, 6500 meters base station power supply system and the equipment disposition, the direct current system voltage parameter setting, the electric surge protection and so on. The fifth chapter for the base station construction design, included: base station construction design information, construction design proposal. The sixth chapter for the project summary and the budget mainly includes the test reports and the technical difficulties and the key points and the innovation of the implements in this project. The integrity, reliability, rationality and the usability of this design proposal have been verified strictly by Olympic flame cross Mount Everest on May 8, 2008. It proved in this plan that the network plan, the product performance, the install craft, the technical specification fully completely defer to the design theoretical value to realize, it has served the engineering construction purpose, safeguarded the Olympic flame to reach smoothly Mount Everest, and realized the Chinese Mobile Group to Beijing Olympic Games Organization committee's pledge!... |
