    Hello, depending on the option selected under the ray tracing settings either the power contributions of the individual rays are added or the phase is considered (coherent superposition): Results from different transmitters can be also combined in ProMan by loading the first result (.fpp file) and then superpose the second result file .fpp via Edit => Add Data. Please have a look in the WinProp user manual.

    Hello, please use the attached .wst file for the definition of 5G TDD network planning projects in ProMan for frequency range FR2. 5G TDD n257 100MHz.wst
  3. Hello, ProMan can be started with additional arguments passed in the command line in order to load and execute existing projects automatically. The first required parameter, which has to be passed to the command line is the path and the name of the ProMan project file to be loaded. Afterwards the prediction mode has to be specified. Please have a look for further details in the WinProp user manual. The alternative way would be using WinProp via API which is also included in the installation, e.g. under C:\Program Files\Altair\2019_2\feko\api\winprop. Please have a look in the corresponding WinProp API documentation.
  4. Hi, often the files on the C drive are protected, so you should either install the WinProp API package on the D drive or run Visual Studio as administrator.
  5. As far as I see you defined a time-variant box and transmitter in your ProMan project. Which version of WinProp do you use? Please send your project (after export via File => Export => Export to zip) via e-mail (to reiner.hoppe@altair.de) and we will have a look. Generally the time-variant simulation is done as a loop over stationary snapshots (after having moved all the time-variant objects to the current position), so as workaround you can also save the stationary approach and define one project per time step in ProMan with the corresponding .idb file.
  6. Hello, the results on prediction planes can be exported to the ASCII line format via File => Export => Export Data (Planes), such ASCII files can be visualized in other software tools. In ProMan the results on (arbitrary oriented) prediction planes are only shown in the 3D view, here you can define by zooming etc. a nice view so that the prediction plane is fully visible and then save this view using the "Store" button on the upper right. For the next result (e.g. after having changed the project settings and rerun the simulation) you can then switch to the same view from the "Camera" drop down list in the upper right. Furthermore you can use the button "Save View to Image" to save the picture as .bmp, .jpg, or .png. All these buttons are only shown in the 3D view.
  7. Hello, the WinProp results are generally deterministic and consider the defined environment, so the results are also reproducible, i.e. if you run the simulation twice you will get two times the same results. The radio channel is generally subject to slow and fast fading. The slow fading represents the average signal levels, e.g. if you are behing a wall you get on average a lower signal level because of the shadowing due to the wall. The fast fading represents the "random" fluctuations due to changes of the phases for the individual propagation paths (rays) which are then either superposed contstructively or destructively at the receiver antenna. The fast fading can be reproduced in WinProp by using the standard ray tracing and activate the coherent superposition under the ray tracing settings. Then you will see the "random" fluctutaions of the signal level over short distances. Nevertheless also in this case the results are reproducible, but you might change the transmitter position slightly or analyze the signal levels at different receiver positions to see the fast fading and the random impact.
  8. Hello, after having defined the time-variant vector database (.idb file) in WallMan you can also check using the "time control" panel if the time-variant objects are moving as expected. Then you define a new propagation study in ProMan and select the "time-variant scenarios" and the corresponding .idb file. Under "Project => Edit parameters" Simulation tab then the field to define start time, end time and interval should be available. Generally we recommend to use the latest version of WinProp which is 2019.2.
  9. All the WinProp binary result files can be exported to ASCII formats (grid or line) in ProMan under File => Export => Export Data (Area). Alternatively the results can be directly written during the simulation in the ASCII grid format by activating the option "Additional output of results in ASCII files" under the Propagation tab of the project parameters in ProMan.
  10. Hello, using a network planning project in WiinProp you can consider the noise power (which depends on the bandwidth and noise figure of the receiver) as well as the co-channel interference from neighboring cells. Both will limit the signal-to-noise-and-interference-power ratio (SNIR). Please have a look in the ProMan manual for further details about defining and running network planning projects in WinProp. Best regards
  11. In ProMan under Edit => Convert unit it can be changed:
  12. Via File => Export => ASCII
  13. Please find attached your .odb file saved with a previous version of WallMan, so that it can be loaded in the 2019 version. However you will need to rerun the preprocessing for the urban IRT model (creating the .oib file) in case you want to use the IRT model. Otherwise you can continue with the DPM model. Which version did you use to create the original .odb file? Laurentides12_3.odb
  14. Hello Terry, the .add file with additional data from open street map can be loaded in ProMan (just for display, i.e. not considered in the wave propagation simulation) by using the following steps: Load in ProMan the project (.net) based on the corresponding .odb file Then in the menue select Display => Additional Data: Layer Management Select "Load" in the shown dialog: Press OK and all the loaded layers from the .add file will be displayed in ProMan: Best regards, Reiner
  15. Hello, in order to create a urban building database based on a scanned bitmap please select the following options after File => New Database: Next there will be a dialogue to enter the UTM zone (e.g. 32 for Germany) and then another dialogue will allow to load the bitmap. The detailed steps are described in the WallMan manual chapter 3.4.4. Alternatively to the manual drawing based on imported bitmap you might try to use another format for the import, e.g. MapInfo or DXF/DWG if QGIS allows you to save the building data in one of these formats which are also supported by WallMan.
