摘要

随着电信市场竞争的日益加剧，移动通信的网络覆盖、容量、质量是运营商获取竞争优势的关键因素。而网络覆盖、网络容量、网络质量从根本上体现了移动网络的服务水平，是所有移动网络优化工作的主题。室内覆盖系统正是在这种背景之下产生的。

随着城市现代化建设的不断发展，高楼大厦日益增多，这些大规模的建筑群和复杂的结构，对移动通信信号有很强的屏蔽作用，使得这些新建建筑和受影响的建筑中出现移动通信信号的盲区，迫使移动用户不能进行正常的通信及其他服务。在大型建筑物的低层、地下商场、地下停车场等环境下，移动通信信号弱，手机无法正常使用，形成了移动通信的盲区和阴影区；在中间楼层，由于来自周围不同基站信号的重叠，产生乒乓效应，手机频繁切换，甚至掉话，严重影响了手机的正常使用；在建筑物的高层，由于受基站天线的高度限制，无法正常覆盖，也是移动通信的盲区。另外，在有些建筑物内，虽然手机能够正常通话，但是用移动户密度大，基站信道拥挤，手机上线困难，由此可见室，内覆盖迫在眉睫。

本课题就邮科院图书馆为例，通过了解室内覆盖设计的理念、直放站的室内覆盖接入方式、图书馆建筑物的特点及设计图工具的使用等诸多方面，设计一套室内覆盖的方案，从而优化图书馆内的盲区，提高用户的通话品质。

Abstract

As the telecommunication market competition is intensifying, the mobile communication network coverage, the capacity, the quality are the operation business gain competitive advantage key aspect. While the network coverage, the network capacity, the network quality fundamentally have manifested the mobile network service level, is all mobile network optimization work subject. Indoor coverage system is precisely generated in this background.

With the continuous development of city modernization, and the increase of skyscrapers, these large-scale buildings and its complex structure, it has the very strong shielding effect to the mobile communication signal, it makes these new buildings and affected buildings appear to the blind area of mobile communication signals, forcing the mobile subscriber can not carry out normal communication and other services. Under the environment of in the lower layer of large buildings, underground shopping mall, underground parking and so on, mobile communication signal is weak, mobile phone cannot be used normally, the formation of a mobile communication blind area and the shadow area; in the middle floor, because around the different base station overlap, from the formation of ping-pong effect, frequent switching of mobile phone , and even lost, serious influence normal use of the mobile phone; in the building of high-rise, due to the highly restricted by the base station antenna, is unable the normal coverage, but also the blind area of mobile communication. In addition, in some buildings, although the mobile phone can communicate normally, but the mobile user density, base station channel congestion, difficulty of mobile phone line, therefore, indoor coverage is imminent.

This topic takes the WRI library as example, through the understanding of many aspects of the characteristics of indoor coverage design concept, the repeater indoor coverage access mode, library building feature and design tools, design a set of indoor coverage solution, so as to optimize the blind area, and improve communication quality of users.
