TD-SCDMA/LTE展览馆室内覆盖系统的设计 摘要 本文通过对TD-SCDMA及TD-LTE原理进行分析，参照有关设计依据及技术指标，分析完成了宁波会展中心2号馆平层及电梯的信号覆盖设计。 室内无线覆盖是针对室内用户以改善建筑物内无线通信环境的一种方案，近些年在全国各地运营商中得到了广泛应用。室内覆盖系统通过需求分析效果预测，全面改善建筑物内的通话质量，提高移动电话接通率，不仅扩大网络容量，更从整体上提高移动网络的服务水平。 论文首先通过对会展中心2号馆信号情况的勘测，完成对会展中心2号馆话务量需求的分析，然后分析信源功率，最终确定了所选用的信号源，同时也确定了所选用各种无源器件。之后对该设计进行覆盖效果的理论预测，确定设计结果达到了相关的技术指标，解决了该馆的手机用户需求，实现了移动通信的无缝覆盖。在设计的最后，进行了施工规范及工程施工流程的说明，列出所用工程材料清单，以便于工程具体实施。 关键词：　TD-SCDMA，LTE，室内覆盖，信源，分布系统 Abstract The design analysis the Principle of TD-SCDMA/LTE, reference to the design basis and technical indicators, analysis of the Convention Center Hall floor and elevator design of the signal coverage. Indoor coverage for indoor users to improve the building environment of a mobile communication program in recent years across the country mobile operators has been widely used. Indoor coverage systems, can provide a more comprehensive manner to improve call quality in buildings, it also improve the mobile phone through rate and open up high-quality indoor mobile communication areas; At the same time, the use of micro-cellular system can be shared outdoor macrocell traffic and expand network capacity, to increase the overall level of service for mobile networks. Through investigation, completed an analysis of traffic demand for Convention Center Hall II, and then Analysis of the power source, ultimately determine the selection of the signal source. Then determine the choice of a variety of passive components. After the design of the cover effect, I determined the design of this technology to meet the relevant indicators. Solve the building needs of mobile phone users; achieve seamless coverage of mobile communications. In the final, I analysis the construction specifications and construction processes. List the materials which were used in engineering, in order to facilitate the implementation of project specific.
