  1. 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
  2. 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
  3. 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.
  4. So far WinProp can be used up to 100 GHz. Basically at higher frequencies the diffractions will disappear, for the other interaction types the material properties need to be adapted. So it should be feasible to increase the upper frequency limit in the mid term.
  5. Hello, the shapefile should contain the buildings as closed polygons. The polygon should not intersect itself, which means that the sequence of corners is not correct. According to the error message shown from your side this seems be to the reason why the building cannot be imported. If possible we recommend to use the MapInfo format for import in WallMan. But the shapefile format will also work if the buildings are defined correctly. Best regards
  6. Hello, in case the transmitter was modified the results become invalid and need to be re-computed. Please press the RunPRO button for re-computation and in case of a network planning project then also the RunNET button for computation of the network planning results.
  7. Hi, this error means that the network planning simulation cannot be started because of the missing path loss results. Please have a look in the ProMan progress window (Antenna tab) to get more details why the path loss results cannot be computed with RunPro. Just scroll up in this progress window until you will the corresponding error message given in red. Best regards
  8. When having started ProMan (which is the main tool of WinProp) the ProMan manual can be launched via F1 or by using ? => User Manual from the menue.
  9. No the coupling between the antennas is not considered, i.e. the MIMO performance is analyzed evaluating the correlation of the antennas due to the radio channel (multipath situation).
  10. Please wait for the next WinProp update 2018.2 which should solve the reported problems when using OptMan.
  11. Please find attached a simple sample project showing the prediction on prediction planes: When loading an .idb file with prediction planes there is an additional option on the Simulation tab which can be activated (please note that the DPM is not available for the prediction on planes): PredPlanes_2018-09-28_10-29.zip
  12. First you need to convert every .hgt file into the .tdb format. Then there is the following way to combine multiple topo files in ProMan which can then be used for simulations: Load the first *.tdb file in ProMan and combine the second *.tdb file via Edit => Combine Data => Max Value Fill the undefined pixels using Edit => Modify Data in Area => Interpolate Data Save the resulting topo data into a new *.tdb file via Data => Topo Database => Save As For rural scenarios the predictions can be also done for individual Rx points (under the simulation tab you can enter the points). If the maps are in metrical UTM coordinates you need to convert first long/lat to UTM (in ProMan under Data => Convert Coordinate Datum).
  13. The superposition of the individual coverage results can be done automatically in a network planning project by RunNet. For this purpose you would need to define a network planning project in ProMan based on the corresponding air interface (wireless standard definition file *.wst). Without network planning project (i.e. in a propagation project) the coverage of individual Tx antennas/leaky feeder cables can be superposed in ProMan by using the following steps: First load one of the results (preferably *.fpp file) in ProMan via File => Open Result and then superpose the next result via Edit => Combine Data => Max Value (can be done for further results in the same way).
  14. The observered problems with the 3D view indicate that the DirectX DLLs are not correctly installed. Typically this should work using the updater, but as you still have problems I would recommend to download and install the required DirectX package from the following link: https://www.microsoft.com/en-us/download/details.aspx?id=8109 For the commercial version please use the contact sheet under the Altair webpage: https://altairhyperworks.com/ContactUsFormHW.aspx Otherwise please let us know your e-mail address and we will connect you directly with the Altair team in China.
