Non‑Negligible Influences of Rain on 5G Millimeter Wave Terrestrial Communication System

Abstract

The impacts of rain on millimeter wave (mmW) terrestrial links, which are inev‐ itably affected by ground-objects-induced multipath propagation, are presented based on the signal time series data measured at 35 GHz. We analyze the coupled influence mecha‐ nism of rain-induced and ground-objects-induced multipath propagation on mmW terres‐ trial links. It can be deduced that the rain-induced impacts on millimeter wave terrestrial links cannot be neglected. The results given in this paper are significant for developing 5G millimeter wave terrestrial mobile communication links.
