本文介绍了毫米波（mmWave）的穿透损耗测量和分析，在73 GHz的宽带滑动相关器信道探测器在室内办公环境。使用仔细控制的测量装置测量许多常见室内建筑材料的渗透损失，例如玻璃门、玻璃窗、壁橱门、钢门和白板书写墙。使用窄波束发射器（TX）和接收器（RX）喇叭天线进行测量，这些天线与天线之间的测试材料对准。总体而言，对6种不同材料的21个不同位置进行了测量，以便在至少两个位置对相同类型的材料进行测试，以表征具有相似成分的材料的渗透损失的影响。如图所示，对于共极化天线，通过普通材料的衰减范围在0.8 dB/cm和9.9 dB/cm之间，而对于大多数材料，交叉极化天线表现出类似的衰减，但对于其他材料，衰减高达23.4 dB/cm。这里提供的穿透损耗结果对于特定于站点的规划工具非常有用，这些工具将对室内毫米波网络进行建模，而无需进行昂贵的测量活动。
This paper presents millimeter wave (mmWave) penetration loss measurements and analysis at 73 GHz using a wideband sliding correlator channel sounder in an indoor office environment. Penetration loss was measured using a carefully controlled measurement setup for many common indoor building materials such as glass doors, glass windows, closet doors, steel doors, and whiteboard writing walls. Measurements were conducted using narrowbeam transmitter (TX) and receiver (RX) horn antennas that were boresight-aligned with a test material between the antennas. Overall, 21 different locations were measured for 6 different materials such that the same type of material was tested in at least two locations in order to characterize the effect of penetration loss for materials with similar composition. As shown here, attenuation through common materials ranged between 0.8 dB/cm and 9.9 dB/cm for co-polarized antennas, while cross-polarized antennas exhibited similar attenuation for most materials, but up to 23.4 dB/cm of attenuation for others. The penetration loss results presented here are useful for site-specific planning tools that will model indoor mmWave networks, without the need for expensive measurement campaigns.
