室内覆盖系统和直放站在移动通信网络优化中的应用

Application of Indoor Antenna Distribution System and Repeater in Optimizing Mobile Network System

随着上海城市建设不断发展,高楼及大型建筑越来越多,这些建筑规模大、结构复杂,对移动通信信号有很强的屏蔽作用,导致建筑群区域内形成信号覆盖盲区,用户难以正常通话。移动通信的网络覆盖、容量和质量是运营商赢得竞争优势的关键,它们从根本上体现移动网络的服务水平,是所有移动通信网络优化工作的主题。文中主要介绍网络优化中室内覆盖系统和直放站的工作原理、功能和应用,以及对网络覆盖、容量和质量产生的影响。

With the continued development of urban construction in Shanghai, more and more high-rise buildings and large scale structures are being constructed. The scale of construction is getting larger and the structure getting more and m ore complex. These structures have very strong shielding effect on mobile commun ication signals forming blind areas of signal coverage within building lots such that it is quite difficult for subscribers to make calls normally. Network cove rage of mobile communication, its capacity and quality are the key factors for o perators to gain competitiveness. These basically reflect the service level of t he mobile network and are the theme of mobile communication network optimization . This paper mainly describes the principle of operation, function and applicati on of indoor antenna distribution system and repeater equipment and the effect o f optimization on network coverage, capacity and quality.
