Overwater point-to-multipoint radio pathloss characterization and modeling

This paper presents experimental results of overwater radio path loss in the 4.4 to 5.0 GHz band. These measurements involve horizontal and vertical polarizations. Based on electromagnetic theory, a deterministic two ray model that mimics measurements is developed.

The model can predict the received power level for all distances lower and higher than the critical distance. The model is consistent with measurements in MIMO modes using any kind of linear polarized antennas.
