A Study on W-Band Frequency Attenuation in the Presence of Human Blockage

The fifth generation (5G) of mobile communications has been established as the current paradigm. Nevertheless, it has some limitations for cutting-edge applications. The sixth generation (6G) is being conceived to approach these new services. It is expected to reach 1 Tbps with ultra-low latency communications, which will be possible by enabling sub-THz and THz frequency bands. These bands are challenging in terms of propagation since the diffraction phenomenon is degraded by blocking due to the size of the objects in terms of wavelength. Therefore, Non Line-of-Sight (NLoS) condition produced by the human blockage is not negligible for communication reliability. In this work, the signal attenuation and the blockage duration produced by human blockage are analyzed in the W-Band (75 - 110 GHz). The study shows significant differences in terms of the frequency within the W-Band, the distance between antennas, the human blockage orientation, or the blockage human sample.
