文档介绍：毕业设计中文摘要
随着社会的发展,城市中移动通信用户的飞速增加以及高层建筑越来越多,话务密度和覆盖要求也不断上升。由于现代城市建筑都是框架结构,而且规模越来越大,对移动通信信号有很强的屏蔽作用,室内信号覆盖有待提高。
本文主要是为邢台丰南联通分公司附属楼做室内信号覆盖,提出了比较完善的覆盖方案。包括站点勘测,场强和通话等级分析,信源的选取,信号分布系统的选取,室内分布系统中天线的选取,室内覆盖中场强的计算和工程实施,最终完成了对该站点的室内信号覆盖。

Title Research for indoor coverage based on work
Abstract
With the development of society, the city's rapid increase in mobile users and more and more high-rise buildings, traffic density and coverage requirements are also increasing. As the modern urban buildings are frame, and the increasing scale, the munication signal has a strong shielding effect.,indoor coverage has e one of the problems solved.
This article is to do indoor coverage for the sub floor, Xingtai Branch Fengnan and makes a plete coverage of the program. It includes site investigation, field and call level analysis, source selection, the selection of signal distribution systems, the selection of antennas of indoor distribution system, calculation of field strength and implementation of the project pleted for this building indoor signal coverage at last.
Key Words :Indoor coverage 、Source、 Field strength
