GSM网络室外直放站的设计

Design of GSM outside and special enlarger

为了解决GSM无线网络中由于各种原因影响达不到无缝隙覆盖问题,采用上下行天线接口之间信号耦合的反馈放大方式,设计稳定性和覆盖两个方面兼顾的室外直放站系统。试验结果表明,使用室外直放站解决覆盖盲区和信号弱的问题是一种快捷、经济的好办法,提高了基站边缘地区的信号强度,改善了通话质量。室外直放站设计的关键技术、相关分析及主要步骤能给业内同行在解决网络覆盖问题时提供一些有益的帮助,也能为业内同行在这方面作更深入的研究,探索出更好、更有效的解决方案提供便捷。

To solve GSM wireless Internet ,for some reasons, cannot reach a completely perfect coverage. In some remote cuntrisides for plants and mine industries in blind areas, it's a fast and economic way to take advantage of an outside and special enlarger. THE system of the outside and special enlarger mainly may be designed in steady plan and covering plan. This article mainly introduces the key technology relational analysis and chief procedure of designs in outside and special enlarger. The author hopes it can provide some beneficial help to persons of this occupation to solve problems about coverage of GSM .moreover, it can make persons give to do more research and obtain better and more effective solution.
