摘要
随着3G时代的到来，移动通信系统得到了越来越广泛的应用，同时，人们对通信的质量和范围提出了越来越高的要求。由于大量高速数据与多媒体业务，如视频电话、游戏等高速数据业务一般都发生在舒适的室内环境中，这些业务功能都需要较大的系统容量和良好的网络质量，才能满足用户对质量的要求，因此良好的室内无线信号覆盖技术日益受到重视并广泛应用。
解决室内覆盖的主要方法是建设室内覆盖分布系统．室内分布系统的基本原理是将室外信号通过有线方式引入到室内，再通过小型天线将信号发送出去，从而提高室内覆盖水平。
本文将在TD-SCDMA室内分布系统建设的分析基础上，借助实习单位的工作内容，对一个实际室内覆盖分布系统建设的进行方案实施，从中总结出一些工程经验。

ABSTRACT
With the age of 3G coming, mobile communication system has been applied widely. However, people put forward higher requirements on the quality and scope of communication. Since a large number of high-speed data and multimedia services, such as video telephony, gaming, are generally happened in a comfortable indoor environment. Only there is a large network of system which has capacity and good quality, that can meet user requirements of quality. So, technology of good indoor wireless coverage is widely used and paid attention more and more.
The main way to solve indoor coverage is to build indoor coverage distribution system. The basic principles of indoor coverage distribution system is putting the outdoor signal through the wire introduced into the room, then sending out the signal through a small antenna so as to enhance the level of indoor coverage.
Based on the theoretical analysis of indoor distribution system, this paper shows the implementation of the actual project on the indoor coverage distribution system. And some experience gained may be useful to similar projects.
Key words：3G; TD-SCDMA; Indoor coverage
