Millimeter-wave propagation modeling and characterization at 32 GHz in indoor office for 5G networks

摘要

Since it has a great bandwidth that supports gigabit communication, it is consideredto use the millimeter-wave (mmWave) band in the fifth generation(5G) wireless communication. Therefore, an efficient, reliable, and accuratechannel 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 characterizationcampaign at the 32 GHz in a typical indoor office environment on fourth floorof the Engineering Faculty in University of Karabuk, Turkey. The obtainedresults provide large-scale fadings such as path loss, shadowing, root meansquare (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. Wepropose that the results obtained in this study will play a key role in simulatingand planning systems at 32 GHz for 5G wireless communication.
