Indoor wireless channel characterization in the W band for the planning of 6G communication systems

This work presents a wireless channel characterization based on an extensive campaign of massive multiple-input multiple-output (mMIMO) measurements conducted under line-of-sight (LOS) conditions. These measurements focus on the 94 GHz band (W band), and the results are compared to the same positions measured at 60 GHz. The values of the relative received power, root mean square (RMS) delay spread, maximum excess delay (MED), and coherence bandwidth in an indoor laboratory environment are analyzed. The results of this study can contribute to a better understanding of the propagation channel behavior in the 94 GHz band, and can be used to assess the potential of this band for the upcoming sixth-generation (6G) networks in laboratory environments.
