Load antenna pattern in Proman from WinPropCLI

Hi,

I am trying to run a particular Proman project with different Tx antenna patterns using WinPropCLI. A simple code to run the project and save the results worked with: WinPropCLI.exe -F "C:\Users\Documents\indoor_winprop_test.net" -A --results-pro "C:\Users\Documents\Results\Run".

But it did not work when I tried to load a pattern using, eg: WinPropCLI.exe -F "C:\Projects\MyScenario.net" -A ^
--results-pro "C:\Results\Run1" ^
--antenna "C:\Antennas\Pattern1.ffe". Could you suggest any modifications or any other resources? Thank you.

Regards

Saurav

Hi @Saurav_Roy , sure, here are my answers:

The option you used is for array antennas. And not for simulating two different independent Rx receivers in the same project. What you are looking for can either be done by running the project twice, once with each MS antenna pattern defined, or creating two separate projects, one with each Rx. Another way, is to use the Propagation Postprocessing incl. Tx and Rx. feature (from the Computation Menu) . In this workflow, you first run the propagation computations without any MS defined. You then use this postprocessing option for each MS. This will save the postprocessed results in the output directory.
In the Edit Project Parameters window, under the Simulation tab, you can switch from Rectangular Area to Multiple Points or even Trajectories. You can then set the coordinates of the points of interest:

Hi @Saurav_Roy

The power results you see displayed in the GUI depend on which output you have selected to view in the result tree: Power, Power MS or Total power. These are the results you have requested in the Propagation tab. On another hand the Ray Data file *.ray contains multiple outputs, including the real/imag field components. You can use this to compute the phase of the received single or any other output.
You can display the rays for any computed pixel, whether in a 2D area simulation or from a multiple points simulation from the Display Rays button shown below.

For this you need to activate the computation of the Propagation paths in the Propagation tab
Note that all the computed path per pixel are also reported in the output files saved on your machine. You can activate the saving of output files in ASCII format.

@Saurav_Roy , can you please report the error you are getting when running the command?

On the other hand, - - antenna is not part of the available options. Can you please point out to where you saw that?

Hi @Zeina, I was able to solve this problem by directly editing the .net project file. But I have two follow-up queries with Proman simulation set-up, It will be very helpful if you can help me with them.

I have a receiver antenna with two output ports giving two patterns. I was able to add them in Edit project parameter > Consider Antenna of MS > individual location offset for each element - I added 2 Rx antennas with two patterns at the same location. But when I run the propagation, I get only one result. How do I get two results from two different Rx antennas from the simulation?
Instead of calculating the results for the entire domain can I set 5 Rx grid points, simulate only them?

Hi@Zeina, Thanks a lot. I will try these.

Hi@Zeina, I was able to solve the previous issues with your suggestions. I have two more queries, could you please help me here?

From the proman simulation, I want a complex Rx signal output (or the complex channel coefficient). From the simulation results, I get power [not sure if this is the same as edit project parameter > superimposed received power > Coherent Superposition (Phase considered) ] and the delay time and path loss. I am using the 3D Standard
Ray Tracing model, where I do not know how the delay time and path loss are related. Can I take the power as the overall power, and is there any way to calculate the total phase of the coherent received signal?
Currently, the power output shows a 2D/3D color plot of the signal strength. For the discrete Multiple Points of the Rx, is it possible to observe all the ray-paths individually?

With regards

Hi@Zeina

I have two follow-up questions from the previous discussion:

a) I have added a Rx antenna pattern in Edit project parameter > Consider Antenna of MS as in the attached picture. Then I run the simulation, but to my surprise, the output Rx power and field strength remains same. Is there any mistake here?

b) I can change the orientation of the Tx antenna by any amount of azimuth shift but elevation shift is limited to 20 degrees only. Is there any other way of tilting the pattern to any angle or aligning the pattern to a certain coordinate axis?

Thank you and regards

Saurav

Hi @Saurav_Roy ,

a) The difference should be observed between Power and Power (MS). Have you compared these together? Of course, the difference will also depend on the gain pattern you have used for the receiver, and the values of the gain. Without the project I cannot comment much.

b) You can normally go beyond 20 degrees of down-tilt, where are you seeing/facing this limit? In any case, another way is rotating your pattern before using it in ProMan (depending on the source of the pattern and how you generated it).

Hi@Zeina

Thank you for the reply. I found the MS results in a different folder.

The restriction on down tilt was found in the cell definition as in the attached picture.

Hi @Saurav_Roy ,

I see that you are running full polarimetric analysis. Indeed, for this case the 20 degrees limit is set to guarantee the results when it comes to the H and V polarization after the mechanical tilt is applied. For degrees above this angle the polarization results will diverge as they don't follow the tilt. This might be changed in future releases.

Nevertheless, for now, you should rotate your pattern before using it in ProMan.

Best,

Zeina
