高话务楼宇TD-SCDMA室内分布系统的设计与实现(硕士)(论文38000字)
Design and Implementation of TD-SCDMA Indoor Distribution System in High Telephone Traffic Building
摘  要
长期以来室内一直是无线通信业务量发生的主要场所,室内话务量至少占70%,随着移动互联网时代的到来,这种趋势更为明显。室内无线通信系统已经成为移动通信产业链上的重要环节,室内网络覆盖和容量越来越难以满足日益增长的用户需求。室内分布系统是移动通信网络的自然延伸,运营商需要重点打造承载高速数据业务的网络,增强室内深度覆盖和话务吸收能力。
本文基于TD-SCDMA(Time Division-Synchronous Code Division Multiple Access)技术基础,介绍了高话务楼宇的室内分布系统。室内分布系统的建设是一项十分复杂的系统工程,涉及规划、勘测、涉及、工程实施、验收、测试、优化、维护等多个环节,信源、直放站、无源器件、天馈系统以及参数优化都会对室分系统的网络质量产生直接影响。作者主要完成的工作如下:(1)立足于具体的工程案例,对现场进行勘测,根据该案例的勘测信息选取采用BBU(Building Baseband Unit)+RRU(Remote Radio Unit)光纤分布覆盖方式。根据设备厂家提供的平面分布图,确定BBU、RRU、各层天线的位置和数量以及具体的走线路由,并指出室内分布系统覆盖工程实施中的注意事项。(2)针对本工程案例的性质,设计出独有的测试方案。根据覆盖测试、容量与链路质量测试、切换测试、覆盖效果测试的实际测试结果,有针对性的对该工程案例进行优化。(3)立足本工程案例,详细说明室内分布系统干扰排查和定位思路,以及如何采取针对性的干扰处理措施。 [版权所有:http://DOC163.com]
本文运用TD-SCDMA技术,结合具体高话务工程案例,从设计到实施,从测试到优化,做出一套完整的室内分布系统解决方案。室外3G网络已经足够先进,现在最需要继续发展的就是室内3G网络,高楼大厦的建设给城市带来经济发展的同时也带了许多全新的挑战,希望能够做到优异的网络覆盖面、高标准的信号质量、超大的信号容量。

Abstract
For a long time, indoor places have been major sites for wireless communication business and indoor telephone traffic takes up at least 70%. With the coming of mobile Internet era, this tendency has become increasingly obvious. Indoor wireless communication system has become an important link in mobile communication industry chain, and indoor network coverage and capacity is becoming more and more difficult to satisfy the ever-increasing users’ demands. Indoor distribution system is a natural extension of mobile communication network, so operators need to make special effort to create network which bears high-speed data traffic and strengthen indoor deep coverage and telephone traffic absorbing capacity.

This thesis is based on TD-SCDMA(Time Division-Synchronous Code Division Multiple Access)technology basis and it introduces indoor distribution system of high telephone traffic building. Construction of indoor distribution system is a complicated systems engineering, involving multiple links such as planning, survey, design, project implementation, acceptance check, testing, optimizing, maintenance and so on, and information source, RPT (Repeater), passive device, antenna feed system as well as parameter optimization will all have direct influences on network quality of indoor distribution system. The author has completed the following work: (1) establishing on specific project cases, surveying the scenes, choosing and adopting BBU(Building Baseband Unit) +RRU (Remote Radio Unit)optical fiber distribution mulching method according to the survey information of the cases; determining location and number of BBU, RRU and antennas on each level as well as specific wires and routes according to the plane distribution provided by manufacturers and pointing out matters needing attention of indoor distribution system coverage projection implementation. (2) Aiming at properties of this project case, designing unique testing project. According to actual test results of coverage testing, capacity and link quality testing, switch test and coverage effect testing, optimizing the project case with pertinence. (3) Based on this project case, elaborating indoor distribution system interference investigation and positioning thinking as well as how to adopt targeted interference treatment measures.

This thesis makes use of TD-SCDMA technology, combines specific high telephone traffic project case and makes a set of integrate indoor distribution system solution projection from design to implementation and from testing to optimization. Outdoor 3G network is advanced enough, so currently what needs development most is indoor 3G network. Construction of high-rise buildings has brought whole new challenges to cities when it brings economic development, hoping to make excellent network coverage, high-standard signal quality and super-maximal signal capacity.
