Analysis on Human Blockage Path Loss and Shadow Fading in Millimeter-Wave Band

الملخص EN

Millimeter-wave (Mm-w) is the trend of communication development in the future; users who carry mobile communication equipment could be blocked by others in a crowded population environment.

Based on Shooting and Bouncing Ray (SBR) method and setting up different orientation receivers (RX), population density, and people fabric property at 28 GHz and 38 GHz, simulating experimental scene similar to station square by Wireless Insite software, we use least square method to do linear-regression analysis for path loss and build path loss model.

The result shows that the path loss index has a certain change in the different frequency, orientation receivers, population density, and people fabric.

The path loss index of RouteC1 and RouteA2 has an obvious change in the central transmitter (TX).

Each route shadow fading obeys Gaussian distribution whose mean is 0.

This paper’s result has a theoretical guiding for designing the communication system in a crowded population environment.
