Will the max interaction number have an influence on the power distribution with 3D ray tracing in urban simulation in winprop?

XW

May I ask if the max interaction number has an influence on the power distribution with 3D ray tracing in urban simulation in WinProp? I tried different max interaction numbers in Proman in my 3D IRT simulation, and found a little difference in the power distribution with more rays. So may I ask if the principle of power distribution in WinProp with 3D IRT is a kind of summing of power for each receiving ray? Many thanks for answering.

Hi XW,

For ray tracing models in WinProp, the received power is calculated by the superposition of all contributions. Nevertheless, depending on the scenario, adding more interactions may not lead to big differences in rx power. Actually, in many urban scenarios, we observe that the main contribution to the received power comes from one main path, what we call a dominant path. This is implemented in the UDP method (Urban dominant Path) in WinProp.

You can try to compare for example simulation results from your IRT simulation, and those from a re-run with the UDP model and check for your case.

I hope this is helpful!

Best,
