The close-in free space reference distance model
CI can be extended to account for the channel shadow fading SF and rain attenuation factors as a different time probability
function. Robustness and performance motivated the adoption
of combining rain fade and shadowing using the CI model at
exceedance probability (0.001%≤P%≤1.0%) and weighing
the path losses using a probabilistic distribution of rain fade
shadowing as a function of link distance. A probabilistic CI
model is proposed considering rain attenuation and shadowing
at different probabilities. The mean estimated path loss in this
new "hybrid" path loss model is probabilistic. The model can
give a close prediction compared to path loss analytically
estimated from measured data at 38 GHz at 300m (χσ = 5.22 dB). The difference between path loss predicted from the proposed probabilistic model and path loss analytically estimated from measured path loss at 38 GHz over 300 m at (0.001%≤p%≤1.0%) has been calculated at the tropical region. The findings show a 20 dB per decade loss in signal strength in the equatorial region more than in the temperate areas by considering rain fade for 300 m at 38 GHz. The proposed hybrid probabilistic path loss model can be used as an alternative to conventional propagation path loss models to calculate the directional path loss by increasing the prediction accuracy. The effect of log�normal shadowing, which essentially accounts for the randomness in the shadowing factor around the cell because of the large obstacles, has also been analysed. Additional transmit power is proposed to maintain the fade margin during the rains. Probbilistic path loss models are commonly used in the design
and evaluation of millimeter wave wireless systems, which
operate at high frequencies and are highly sensitive to the
propagation environment. By accounting for the probabilistic
nature of the path loss, these models can help to improve the
accuracy of predictions and reduce the risk of unexpected
performance degradation in real-world deployments. |
