Because the modern urban architecture frame structure, and large scale on the mobile communication signals have very strong shield effect. In the bottom of the large buildings, and underground shopping malls, underground parking lot environment, and the mobile communication signal is weak, formed the mobile communication of blind area; In the middle of the floor, due to the different from around the base station signal overlap, produce table tennis effect, cell phone frequent switching, and even drop the words, serious impact on the mobile phone use; In the high-rise buildings, as the base station antenna height limit, cant normal coverage, also is the amount of mobile communication; In some buildings, although cell phones can normal conversation, but the user density, base station channel crowded, the mobile phone Internet difficult. Visible, indoor coverage and optimize the urgent problem. This paper mainly studies the GSM network distribution of indoor design (also called the indoor coverage, hereinafter referred to as indoor coverage) and optimization, based on indoor coverage system optimization for simple research and on the basis of analysis, combined with the actual conditions of the library of predominant the survey analysis, we give complete design. Finally using his mobile phone and test software to the scene test, this paper design indoor coverage system is tested and analyzed. 【Key words】ndoor Coverage Network Optimization 目 录 前 言 1 第一章 GSM网络的室内覆盖的意义和现状 2 第一节 GSM网络的室内覆盖的意义 2 第二节 GSM与室内分布系统现状分析 3 一、GSM系统概述 3 二、室内分布系统现状 4 第三节 本章的主要工作 5 第二章 GSM移动网络室内分布系统概述 6 第一节 概念 6 第二节 IDS的类型及其特点 6 一、信号源的分类和特点 6 二、分布系统的分类和特点 7 三、IDS系统结构 10 第三节 本章小结 13 第三章 GSM室内
