摘要
3G 的魅力在于高速数据与多媒体业务,而视频电话、视频流、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。对运营商而言,大量使用室内覆盖系统,可以争夺室内的话务量。室内覆盖还可以用于分散过密地区的网络压力,解决高端用户密集城区覆盖问题,减少室外基站的数量和配置, 降低室外网络的整体干扰水平,从而提高整个系统的容量,更好地满足用户对质量的要求, 其性能的好坏将直接影响到运营商的客户体验及收益,是其取得成功的关键因素之一。
本文对室内覆盖技术进行了研究,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。TD-SCDMA 是 3G 三大主流技术之一,TD-SCDMA 室内分布系统将是 TD-SCDMA 整个网络建设的重点之一。本文对 TD-SCDMA 室内覆盖系统规划与设计要求进行了分析,给出了 TD-SCDMA 室内覆盖常用组网方案。从一些工程经验出发, 分析 TD-SCDMA 室内分布系统设计的特点,对各类典型场景实现方法进行了研究,并结合具体的案例总结出一些方法和技巧。

Abstract
The charm of 3G is high-speed data and multimedia services, and video telephony, video streaming, gaming and other high-speed data services are usually occurred in fortable indoor environment, these business functions require a work of system capacity and good quality. For the operators, the extensive use of indoor coverage system pete for the indoor telephone traffic. Indoor coverage can also be used to disperse the pressure over work density areas, dense urban settlement covering high-end users, reduce the number of outdoor base stations and configured to reduce the overall interference level outside work, thereby enhancing the capacity of the entire system to better meet user quality requirements, the performance is good or bad will have a direct impact on the operator's customer experience and revenue, is the key factor for ess.
This thesis studies the technology of indoor main way to solve indoor coverage is to build indoor coverage distribution system. The basic principles of indoor distribution system is to outdoor signal through wire introduced into the room, then through a small antenna to send out the signal so as to enhance the level of indoor coverage.
