Path Loss Model Parameters
Hello, I have a question about the path loss model. I checked the documentation of winprop and found that the winprop simulation software only provides the setting of the path loss exponent, but does not mention other parameters of the path loss model. Where can I find other parameters （except path loss exponent） to the path loss model? Or I can only set the path loss index, and other parameters can only be obtained by calculation？
(Figure 1 shows the path loss model)

I was not able to find the equation you show. Maybe you can tell me in which section and on which page you found it. Maybe it was in a very general mention of path loss.
In general, WinProp offers many propagation models, each with their own parameters. The parameters are accessible via a Settings button that accompanies the selection of the propagation model, and the meanings of the parameters are described in the manual.
Of course, if the parameters in the equation you show are not explained, we need to improve that part of the manual.

Hello, thank you for your reply, the path loss model in the picture I uploaded is the path loss model in most of the literature, I did not see about the shadow fading factor in the winprop manual, in addition, the description and setting of the parameter alpha in the model Didn't mention it, do you have any solution?

If the picture is still not visible, please read the path loss formula I described in text directly：

The problem was not that the picture wasn't visible. The problem was that I could not find the equation in the WinProp manual. That's why I asked in which section and on which page (of the manual) you found it. I don't know what the alpha and the X in the equation are. The interaction losses at reflections and diffractions must be contained in one of them. Those depend on the particular propagation model. Every propagation model is described in the manual, and interaction losses for ray-based models and for the dominant-path model depend on the material parameters. If there is a general offset term in the path loss, maybe such a parameter is part of some of the empirical propagation models.
