Since it has a great bandwidth that supports gigabit communication, it is considered to use the millimeter‐wave (mmWave) band in the fifth generation (5G) wireless communication. Therefore, an efficient, reliable, and accurate channel model is of vital importance in mmWave bands for indoor environments, especially in the 31.8 to 33.4 GHz band allocated by ITU for 5G communications. In this article, we performed modeling and characterization campaign at the 32 GHz in a typical indoor office environment on fourth floor of the Engineering Faculty in University of Karabuk, Turkey. The obtained results provide large‐scale fadings such as path loss, shadowing, root mean square (RMS) delay spread, RMS angular spread, power angular spectrum, number of clusters, and Ricean K‐factor in an open‐plan indoor environment. Power angular spectrum is used to comprehend the propagation structure. We propose that the results obtained in this study will play a key role in simulating and planning systems at 32 GHz for 5G wireless communication.

室内办公室用于5G网络的32 GHz毫米波传播建模和表征

由于它具有支持千兆位通信的巨大带宽，因此被认为在第五代（5G）无线通信中使用毫米波（mmWave）频段。因此，对于室内环境的毫米波频段，尤其是在ITU分配给5G通信的31.8至33.4 GHz频段中，高效，可靠和准确的信道模型至关重要。在本文中，我们在土耳其Karabuk大学工程学院四楼的典型室内办公室环境中，以32 GHz的频率进行了建模和表征活动。在开放式室内环境中，获得的结果提供了诸如路径损耗，阴影，均方根（RMS）延迟扩展，RMS角扩展，功率角谱，簇数和Ricean K因子之类的大规模衰落。功率角谱用于理解传播结构。我们建议在这项研究中获得的结果将在模拟和规划用于5G无线通信的32 GHz系统中发挥关键作用。
