Abstract

The influence of rain induced electrical conductivity and other environmental factors on millimeter wave propagation have been looked at. From the analysis, it is evident that in majority of the surveyed sites, the predicted and measured power loss values exhibited remarkable agreement, with deviations remaining within a narrow margin (< 3dBm). Power loss predictions using the Beer-Lambert Law and its implications for millimeter wave propagation also revealed the influence of rain induced absorption and other environmental factors on signal attenuation. The Beer-Lambert Law serves as a fundamental tool for estimating power loss due to absorption. The power loss (attenuation) due to absorption reflects the trends observed in conductivity-related loss. It is an established fact that the absorption of millimeter propagation waves usually leads to a reduction in the intensity, and consequently, their effective range. The study revealed that high electrical conductivity particularly in raindrop environments results in substantial millimeter wave attenuation. This attenuation is mainly due to increased loss of transmitted power as radio waves interact with raindrops. Power losses due to electrical conductivity in these regions were found to be great with measured values approximating 71dBm to 85dBm.
