论文摘要
未来的蜂窝系统将利用毫米波（MMWave）频带。这些乐队中的许多用户都位于室内，即内部建筑物，房屋和办公室。这些高频范围内的典型建筑材料衰减对于链路预算计算很感兴趣。在本文中，我们报告了一项协作测量活动，以发现三个潜在的MMWave乐队（28、73、91 GHz）中的几种典型建筑材料的衰减。使用定向天线，我们使用窄带和宽带信号在多个位置进行了多次测量，并平均残留的小规模褪色效果。材料包括透明玻璃，石膏板（石膏板），胶合板，声学天花板和煤渣块。特定的衰减范围从28 GHz的天花板瓷砖约0.5 dB/cm到91 GHz的透明玻璃的大约19 dB/cm。
Future cellular systems will make use of millimeter wave (mmWave) frequency bands. Many users in these bands are located indoors, i.e., inside buildings, homes, and offices. Typical building material attenuations in these high frequency ranges are of interest for link budget calculations. In this paper, we report on a collaborative measurement campaign to find the attenuation of several typical building materials in three potential mmWave bands (28, 73, 91 GHz). Using directional antennas, we took multiple measurements at multiple locations using narrow-band and wide-band signals, and averaged out residual small-scale fading effects. Materials include clear glass, drywall (plasterboard), plywood, acoustic ceiling tile, and cinder blocks. Specific attenuations range from approximately 0.5 dB/cm for ceiling tile at 28 GHz to approximately 19 dB/cm for clear glass at 91 GHz.
