RRU与天线一体化设备在TD-LTE网络建设中的应用研究

内容简介：在TD-LTE网络建设中，由于TD-LTE采用的频段较高（2GHz以上），使得新建网络需要增加较多站点。然而对于部分天面资源匮乏的站点，采用传统的新建抱杆、新增RRU+天线的方式将面临诸多困难。介绍了RRU与天线一体化的新形态设备用于解决天馈紧张站点的TD-LTE网络建设方案，并详细对比分析了RRU天线一体化与传统RRU+天线方案的差异，最后对RRU与天线一体化设备的应用场景提供了详细的建议，用于指导TD-LTE网络建设。

Abstract：Due to the high frequency band(2GHz or more) of TD-LTE, new network needs more sites in TD-LTE network construction. The traditional way by building new derrick or increasing new RRU and antenna will face many difficulties for some sites short of antenna resources. A new RRU integrated antenna equipment used to solve the insufficiency of antenna feeder in TD-LTE network construction is introduced. The differences between integrated proposal and the traditional proposal are compared in detail. At last, detail advice for application scenarios of the RRU integrated antenna equipment is provided, guiding the TD-LTE network construction.
