An accurate design of the fading margin in wireless communication networks requires good modeling of the relationship between the rain rate and the attenuation. In this paper, we discuss the effect of the wet antenna (WA) on the fading margin. We claim that this effect is not negligible in commercial $E$ -band (i.e., 60–90 GHz) technologies, where the microwave links are relatively short and the...
A common way to describe the relation between rain-rate R [mm/h] and attenuation A [dB] in radio signal is the Power-Law A = aRb, where a and b are the Power-Law parameters, which depend on the radio signal (frequency, polarization) and on some properties of the specific environmental conditions. These parameters are usually set off-line using special purpose equipment and are used from existing tables...
