随着网络的发展,运营商对深度覆盖的投资越来越大,用户对网络质量的需求也越来越高,而传统的宏站加室分建设的覆盖方式已不能满足高质量网络的覆盖要求。4G牌照发放后,LTE室分的建设既是重点,也是难点,如何让LTE MIMO技术优势在室分落地,如何更好地开展LTE室分的新建及改造,保证建设进度、投资效益、网络质量、用户体验和竞争优势,是运营商和业界关注的重点。基于此背景,新型的光纤分布系统应运而生。本文将从光分布的定义、工作原理、适用场景及其与传统室内分布的对比几个方面,对新型室内覆盖方式-光分布的应用进行探讨和研究。
With the development of the network, operators are increasingly investing in deep coverage and users’ demands for network quality are getting higher and higher. However, the coverage of the traditional macro-station plus room construction can not meet the requirements of high-quality network coverage Claim. After the 4G license is issued, the building of the LTE cell points is not only the key but also the difficult point. How to make the LTE MIMO technology advantages fall into the floor and how to better develop and transform the LTE cell points to ensure the construction progress, investment benefits, network quality, User experience and competitive advantage, is the focus of operators and industry. Based on this background, a new type of optical fiber distribution system came into being. This article will discuss and study the application of the new indoor coverage method - light distribution in terms of the definition of light distribution, working principle, applicable scenarios and its comparison with the traditional indoor distribution.
