  1. How can I change the measurement unit for Field Strength, from [dB uV/m] to [mW/cm^2], in WinProp?
  2. Hello, I have a 3D antenna pattern that was designed in CST Studio Suite 2018 and I want to use it in WinProp ProMan. What is the easiest way to convert the data? Because CST exports 3D patterns in certain formats but none of them is supported by WinProp (AMan and ProMan). Thanks.
  3. In the help file it says that "The user can either select a predefined air interface file (*.wst) which is available from AWE Communications for most of the common wireless technologies ", but I cannot find nor download the wst files to use with ProMan
  4. Hello For a real implementation, I am running simulations of a certain area (parking garage) where the antenna is only 15 cm above the floor plate. I noticed that the results of my measurements differ very strongly from the values I find in the simulation. To check if I had made a mistake I tried to recreate the 2-ray path model using a floor plate with normal material properties (for example concrete). This was successful because the resulting power (and field strength) values decreased with 40 dB per decade as we expect from the theoretical explanation. This of course after the oscillations stop (> critical distance). However, when I rerun this simulation with lower antenna heights (coming from 5 m to 0.5 0 or even 0.15 m) the results get worse and worse. The lower I place my antenna (but still above the floor obviously) the worse my results get. At 0.15 m antenna (and resulting prediction height) I get just over 20 dB/decade. I have graph where I simulated the exact same plate, exact same antenna location, but with adjusted antenna and prediction heights where you can see this trend. I feel as though there is something wrong with either the interaction between the antenna and the floor (incorrect resulting radiation pattern) or that the separate rays don't add up correctly at the resulting point when they are this close together. I have tried this with several material properties but I still get this result. Any help would be much appreciated. Kind regards Publi PS: to recreate the results: Step 1: create database in WallMan, long plate (>2km) of a certain with with 5.5 relative permittivity and 0.01 S/m conductivity. Step 2: Make SRT project and load this into ProMan. Step 3: Place an antenna with normal gain and isotropic radiation pattern and arbitrary transmitted power at the start of the plate. Choose for example 10 m height (also for prediction plane). Step 4: Simulate it and plot the resulting power from the transmitter to the end of the plate. Step 5: Confirm that you have 40 dB/decade power loss. Step 6: Repeat starting from step 3 but now choose a lower antenna height and prediction plane. Confirm that you power loss is now lower than the first case. 2Ray-AntennaHeights.eps
  5. Hello everyone I had some trouble understanding the transmission matrix that ProMan generates. However I found some explanation on this forum which helped me a lot. There is still something i do not understand about this. This other post said the matrix was made independent of the antenne's polarization. But then what does ProMan use to generate these values, how are they calculated? Do they take into account the material properties (for example when there is a reflection)? Thanks in advance for any help! Kind regards Publi
  6. Hello everybody I have been using ProMan for a while now but for certain simulations I get some serious deviations from the theoretical values that I calculated. To identify the reason for this difference I wanted to see the phase of every wave that contributes to the field strength of a point. However the log files that are generated only contain information about the path, transmission matrix, delay, field strength components and so on. I can calculate the phase difference between several paths (for example one direct path and a reflection) based on the delay and path length difference between them but i can't seem to find exact phase information for each path. Is there a way to gather the phase from a path, wether indirect or direct, or does ProMan not have such a mechanism? For the simulation I checked that the superposition of contributions is coherent and considers the phase. These mismatches are mainly present when there are reflections. Thanks in advance. Publi
  7. Now I can just get some terrain information from the prediction result like field strength and LOS If I want to get measurement like RSS、TOA and AOA for each point and export as a txt file How can I do it ?
  8. In MIMO simulations, how does WinProp take the Envelope Correlation Coefficient (ECC) into account? If I specify antenna gain patterns and antenna locations, is that enough or do I need to specify more details? What happens if I specify the same location for two antenna of a MIMO system?
  9. When one simulates Network Planning in ProMan, how does the tool decide on cell assignment? What are the criteria?
  10. In ProMan, when I define a receiving antenna under RunMS, how can I tell in which direction it is pointing? Note that I'm replacing the omni-directional antenna by an imported antenna pattern when I define the properties of the receiving antenna in ProMan.
  11. How theorically ProMan combines data using the command Combine Data - Max Value? Thank you.
  12. Hello, How can I implement my own optimization algorithm in winprop? It is worth to mention that I want to use the algorithm for sites placements depending on several factors like Power, Data Rate, Capacity... etc. I tried using OptMan but there are no resources in that on how to use it. Thanks.
  13. Hi All, Please advise whether we can obtain process reports or run logs for the ProMan propagation runs, WallMan Preprocessing, WallMan Simplification etc., Specifically, am looking to note down the simulation times (start time, end time) and RAM status etc., Thanks a lot Balaji
  14. Hello everyone As a part of some simulations I am running, I tried to simulate a 2-ray path model in ProMan. To achieve this I approximated a PEC in WallMan ( εr =1 (lowest possible), µr = 1, σ = 6e+006 (highest possible)) as a floor plate. In ProMan I simulated an antenna at one end (height 4.5m) and I plotted the received power vs the distance at height 4.5m. Everything about this graph is correct, the locations of the oscillations are exactly where I would suspect them theoretically and once Δ R drops below λ /2 the oscillations stop and I get a constant slope. However due to the small incidence angle and the relative height of the transmitter and respective receiver, I would predict the path loss of this slope to be 4 (40 dB/decade decrease, which I should get regardless of material properties because the angle is so small and I only have the direct ray and the reflected ray). But I never get this value from the simulations. The lower I place my transmitter, the lower the path loss gets. The path loss from every simulation has been lower then the expected value. Does anyone know the reason for this deviation or is someone struggling with the same phenomena? I tried to look for an answer in the manual and found a possible cause for my mismatch. I suspect that my tolerance for the angle of incidence is to low. Therefore ProMan has trouble correctly interfering these two rays. I found a page in the manual, from which I have included a print screen, where oen could adjust this value. However I haven't been able to locate this menu for my simulations. Thanks in advance! Kind regards Publi
  15. Dear All I recently encountered the error from the picture, "Error 953: Not enough interactions (total number) specified". I have had this error before without any actual problems in my simulation. However this time it seems that my simulation stopped calculating way before my prediciton area was filled. I have a long and small prediciton area (1 m wide and 50 km long) but it stops showing values for received power or field strength after 1020 m. Is this just the limit for how many points ProMan can simulate? I have the resolution at 10m so it has the same amount of data points as my previous predictions which are shorter but at a higher resolution (for example 0.2m resolution). Is this related to the error or do I have 2 seperate breaches of conditions? Thanks in advance! Publi
  16. Hi, I have an algorithm for the assignment of mobile stations in WinProp and I am struggling in adding this algorithm to the software. I have read the part of the manual where it shows the API Functions (which by the way I cannot find the NetManTrafficCore.pp file), that are used in Visual Studios but I still don't understand how to implement my own algorithm in WinProp. Also, where can I find the Visual Studio library that will help me in writing the algorithm? Can anybody help with details please? Thanks.
  17. Using Proman I want to create a site with an antenna that is connected to the network as in a default site/antenna. Then, a second antenna/site must be created but this site does not get the data to transmit from the network but instead, it must have a wireless backhaul connection to the first antenna created. How could I go about doing this in Proman if it is possible?
  18. Hi! There is someone who knows how to export all the ray paths after the Propagation Simulation using the Dominant Path Model?
  19. I am trying to create a simple indoor scenario with network planning. I am trying to implement a 2x2 MIMO in an LTE air interface conditions. My question is where can I define the modes that my MIMO is using? For example: is the MIMO being used for Spatial Diversity or Spatial Multiplixing? What type of diversity is it using (Spatial Diversity, Polarization Dicersity., Frequency Diversiy or Time Diversity)? is it an open-loop or closed-loop MIMO? As far as I know, I can only modify the Signalling Overhead, Beamforming and the Interference between the streams, but can I can modify the modes such as the ones I mentioned above? If no, what are the defaults that ProMan is using? Thanks.
  20. Dear Members, I am required to view all LOS servers serving a receiver pixel in the prediction area using network modelling tool. I understand that DPM considers the dominat path and it need not necessarily the line of sight path. Is there a setting which I can change for DPM or any other solver in ProMan to perform only LOS coverage. Please advise. Thanks Balaji
  21. Under the project parameters, on the Air Interfaces tab, there is a mobile station/subscriber station settings option. I would like to know how to implement this in my simulations as i can't seem to see an option to add mobile stations into my simulation
