介绍了室内毫米波的传播特性,通过改变发射天线的位置实际测量了37.598GHz和40GHz毫米波在实验室内和走廊的接收功率,并对数据进行处理,得出毫米波室内视距条件下的基于衰减因子损耗模型的传播路径损耗因子n。分析两种频率的毫米波测量结果,对于室内基站位置的选择和无线终端的设计以及40GHzmm-ROF系统的室内覆盖提供依据。
This paper briefly introduces the characteristics of millimeter-wave indoor propagation.We obtained the 40 GHz millimeter-wave indoor propagation path loss factor on the line of sight(LOS)by measuring and processing the received power both in lab and corridor under 37.598 GHz and 40 GHz respectively.The contrast analysis of the above results provides the theoretical foundation for the selection of in-door base station,the design of wireless terminal and the in-door coverage of 40 GHz mm-ROF system.
