上海移动的TD-SCDMA试验网从07年开始建设至今已近2年,网络已经覆盖了整个上海的市区、交通干线及一些重要的市政工程场点。随着TD网建设的不断推进和深入,TD网与2G网一样,同样会面对上海这个重要港口城市的海面边际覆盖问题。本论文将结合作者在上海的东海大桥及洋山深水港的TD网规划和设计工作中所学习到的相关TD网络规范知识,从TD网无线信道时隙的规范标准上对TD网的远距离覆盖的允许范围及不同覆盖距离对无线容量和质量的影响情况作了分析和讨论,并对洋山港局基站的TD网远距离覆盖的站点设置要求等提出了初步的想法和观点,对实际的站点建设具有一定的指导意义。
Shanghai Mobile’s TD-SCDMA trial network has been under construction for nearly two years since 2007. The network has covered the entire downtown area of Shanghai, major traffic routes and some important municipal engineering sites. As TD network construction continues to advance and deepen, TD network and 2G network will also face the issue of Shanghai’s marginal coverage of the sea in this important port city. This paper will combine the knowledge of relevant TD network standard learned by the author in TD network planning and design work of Shanghai Donghai Bridge and Yangshan Deepwater Port from the normative standards of TD channel wireless channel time slot to the long distance of TD network The coverage of the coverage and coverage of different wireless capacity and quality of the impact of the situation were analyzed and discussed the Yangshan Port base station TD network long-distance coverage of the site set requirements put forward the initial ideas and views on the actual Site construction has a certain significance.
