基于会展中心模型的4G双路由室内分布设计——以南宁国际会展中心为例

摘 要

室内覆盖还可以用于分散过密地区的网络压力，解决高端用户密集城区覆盖问题，减少室外基站的数量和配置，降低室外网络的整体干扰水平，从而提高整个系统的容量，更好地满足用户对质量的要求，其性能的好坏将直接影响到运营商的客户体验及收益，是其取得成功的关键因素之一。

　解决室内覆盖的主要方法是建设室内覆盖分布系统，室内分布系统的基本原理是将室外信号通过有线方式引入到室内，再通过小型天线将信号发送出去，从而提高室内覆盖水平。4G双路由是4G三大主流技术之一，4G双路由室内分布系统将是4G双路由整个网络建设的重点之一。本文将从一些工程经验出发，分析4G双路由室内分布系统设计的特点，并总结出一些方法和技巧。

Abstract

4G is the charm of high-speed data and multimedia services, and video teInc., the implementation of telephone traffic within the building indoor coverage increased 1.43 times. Indoor coverage can also be used to disperse the pressure over the network density areas, dense urban settlement covering high-end users, reduce the number of outdoor base stations and configured to reduce the overall interference level outside the network, thereby enhancing the capacity of the entire system to better meet user quality requirements, the performance is good or bad will have a direct impact on the operator's customer experience and revenue, is the key factor for success.

The main way to solve indoor coverage is to build indoor coverage distribution system, the basic principles of indoor distribution system is to outdoor signal through wire introduced into the room, then through a small antenna to send out the signal so as to enhance the level of indoor coverage. 4G is one of the three 4G mainstream technology, 4G indoor distribution system, 4G will be one of the major construction of the entire network. Some works from this experience, analysis of 4G indoor distribution system design features, and summarize some of the methods and techniques.
