无线通信室内覆盖设计
摘要
3G它的全称是3rd Generation,中文含义就是指第三代数字通信。3G是向未来个人通信演进的一个重要发展阶段,具有里程碑和划时代的意义。1995年问世的第一代模拟制式手机(1G)只能进行语音通话;1996到1997年出现的第二代GSM、TDMA等数字制式手机(2G)便增加了接收数据的功能,如接受电子邮件或网页;第三代与前两代的主要区别是在传输声音和数据的速度上的提升,它能够在全球范围内更好地实现无缝漫游,并处理图像、音乐、视频流等多种媒体形式,提供包括网页浏览、电话会议、电子商务等多种信息服务,同时也要考虑与已有第二代系统的良好兼容性。
室内覆盖是针对室内用户群、用于改善建筑物内移动通信环境的一种成功的方案。本文比较详细的介绍了室内覆盖的具体环节及实施过程。阐述从理论的设计方案到网络优化工程的竣工。室内覆盖原理是将基站的信号通过有线方式直接引入到室内的每一个区域,再通过小型天线将基站信号发送出去,从而达到消除室内覆盖盲区、抑制干扰的目的,为楼内的移动通信用户提供稳定、可靠的室内信号,使用户在室内也能享受高质量的移动通信服务。 室内覆盖系统的建设,可以较为全面地改善建筑物内的通话质量,提高移动电话接通率,开辟出高质量的室内移动通信区域;同时,使用微蜂窝系统可以分担室外宏蜂窝话务,扩大网络容量,从整体上提高移动网络的服务水平。

ABSTRACT
The full name of 3 G is the 3 rd Generation, which of Chinese is third generation of digital communication. 3G is an important of developing stage of gradual progress of personal communication of future and have molestone and epoch-making meaning. first-generation analog mobile phone system (1G) can only be making voice calls since it came out in 1995 the second generation of GSM, TDMA digital mobile phone standard (2G) increase the function of receiving data,such as receiving E-mail and web pages. the biggest defference between the third generation and the first two generations is the promotion at the speed of transmitting sound and data. it can at the global level to better achieve seamless roaming, and to deal with images, music, video streaming and other forms of media provided, including web browsing, conference calls, e-commerce and other information services, we must also consider the second-generation system has a good compatibility.
Indoor coverage interior user groups are targeted for improvement in building mobile communications environment, a successful program. This article describes in more detail the specific aspects of indoor coverage and the implementation process. Explained from a theoretical design of the network optimization project completed.The principle of indoor coverage is that the base station's signal through the cable directly into the interior of each region and then through the small base station antennas to send signals go out, so as to achieve the elimination of interior blind spot coverage, the purpose of interference suppression for the building of mobile communication users to provide a stable, reliable signal of the interior, so that users can enjoy high-quality interior of the mobile communications services. Indoor coverage systems, can provide a more comprehensive manner to improve call quality buildings, enhance the mobile phone through rate and open up the interior high-quality mobile communications region; At the same time, the use of micro-cellular systems can be shared outdoor macrocell traffic, and expand network capacity, improve the overall mobile network service levels.
