基于GSM的敏捷上城国际小区室内覆盖设计

摘要

随着社会的发展和人们对于手机的依赖越来越大，城市中移动通信的用户飞速增加，话务密度和覆盖要求也不断上升。但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。

本文主要是为敏捷上城国际小区做室内信号覆盖，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。

关键词：室内覆盖 场强 信源

THE PLANNING AND DESIGNING OF FIBER ACCESS NETWORK TECHNOLOGY IN AGILE UPTOWN

INTERNATIONAL COMMUNITY

ABSTRACT

Access network technology is a major component of modern telecommunication networks; it is also a hotspot research of modern communication technology. Using fiber access network technology has a large capacity, high speed, long distance and economic coverage and good, it is already the preferred solution of modern access network technology. In this thesis, we completed a design of fiber access network in Agile uptown international community. Firstly, we give the research status for optical access network technology at home and abroad, discuss the importance of the technology. Then we explain the main concepts of optical access network technology, analysis and comparison of the copper access network with fiber optic technology access network technology advantages and disadvantages. In Garden Flower City district, for example, in the case of residential basic user mode with the current situation in the subscriber access network based on fiber access network business development were predicted to discuss and analyze the feasibility and necessity of the technology, studied the PON and EPON technology. Finally, we propose a design of fiber access network technology in the Garden Flower City district. The design focused on the goal of building access networks and ideas are given the choice of network architecture design and equipment, then, for the service carrying capacity and carrying capacity of integrated multimedia service access terminals were analyzed.
