| 摘 要： | 与2G系统相比,TD-SCDMA无论在技术组成、业务支持及工作频段上均有重大差异,因此2G的组网经验在多数情况下不能直接应用到TD-SCDMA上来,比如隧道场景下存在着空间受限,弯道衰减大,隧道内及隧道口切换不稳定,链路预算模型复杂,天线位置不易确定等特点.TD-SCDMA实现在隧道中的良好覆盖具有重要的意义,本文通过实例对该场景下一些普遍性的问题做了具体研究,得出了TD-SCDMA隧道覆盖的一般性解决方案. |

| Abstract: | The experiences we possessed in GSM cannot be directly used in TD-SCDMA network, because there has tremendous difference at the wireless technique,service providing,and work band. Some scenes,for example tunnel, has its special character, like space restricted,curved conduit attenuation,handover instability,complicated link budget and also, antenna position's confirm is not easy. In this article, we discussed some universal principles under tunnel coverage in TD-SCDMA, and provided a general covering soluti... |
