Two-Ray Model Analysis for Overwater Communication at 28 GHz with Different Heights
Ref: CISTER-TR-231203       Publication Date: 6 to 8, Dec, 2023

Abstract:
This research aims to assess the signal propagation behavior of millimeter waves (mmWaves) over maritime environments. It focuses on the path loss performance of shore-to-vessel and vessel-to-vessel overwater communication at 28 GHz when considering line-of-sight conditions. The study is conducted by means of synthetic simulations at four different receiver antenna heights with respect to the water surface, representing emerging maritime Internet-of-Things application scenarios. Simulation results are shown concerning the path loss and the excess path loss – additional path loss relative to that in free-space – for each particular antenna height, over different TX-RX separations. We also show the cumulative distribution function of the excess path loss. The outcomes reveal variations of up to 10 dB in path loss performance depending on the height-distance setup. The results also reveal an initial distance range for all antenna heights in which the excess path loss is below 3 dB with 90% probability.
