Mitigating People Blockage by Angular Diversity at Millimeter Wave 5G Bands

A measurement campaign was carried out in order to characterize the channel response when people are passing between transmitter and receiver in the 5G Frequency Range 2 and beyond (40 GHz and 60 GHz). We also studied the possibility of using angular diversity to compensate for the resultant fading. After analyzing the data, interesting results are obtained: fading values over 25 dB were measured at both bands; the level crossing rate is very similar in value and distribution at both frequencies, and the average duration of the resultant fadings is almost double at 60 GHz. It was also observed that the fading depth seems to be related to the stature of the person obstructing the radio link. A deeper fading is observing with taller individuals.
