  1. 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
  2. Hello everyone, I notice that, for 802.11n 5GHz air interface, max data rates in DL and UL in 64 QAM High Transmission Mode (MCS) is 62.68 KBit/sec. This value seems very low. I understand from literature that 802.11n has a max theoretical data rate of 450 Mbps. I request forum members to please guide me which settings in MCS or anywhere in network planning tool which I need to change to increase this data rate to real world values. Please advise. Thanks Balaji
  3. Hi All, I have been exploring weather WinProp (ProMan) can be used for real time applications. The main obstacle for real time performance is the time winprop takes to provide heat maps. I think, if we could query winprop to provide point to point values instead of a entire prediction plane of many points, then we can unlock its real time potential. Would you please advise if there an API or something through which can accomplish this. Thanks Have a great day Balaji
  4. Thanks a lot reinerh, your advise worked very well. I sincerely appreciate your help Best regards Balaji
  5. Hi all, Please advise if there is a way in which I can obtain difference heat maps for more than 1 antenna in the prediction rectangle. for Example, firstly load 4 antennas into the prediction rectangle using Edit --> Combine data --> Max value. Then, subtract this combined heat map with another combined heat map with 4 antennas which were already loaded using Edit --> Subtract --> Value (File, Linear) . So Its basically 4 antennas - 4 antennas. Is it possible in ProMan. Please advise Thanks Have a great day Balaji
  6. Hi all, The ProMan simulation that am currently working on has close to 30 antennas. It feels tedious and frustrating to do 'Edit--> Combine data --> Max value' manually for each antenna every time I run the simulation. Please help me find out if there is a way where all antennas heat maps can be loaded at one go. Thanks Have a great day Balaji
  7. I got the above dialogue (message) when I did try to compare time variant with non time variant. I needed to compare at time instant t=7 and t=13 for example for my application so current time step of t=0 doesn't work. I used DPM propagation model for my analysis.
  8. In my analysis, I observed that, the time variant and non-time variant simulation results are not exactly identical in the entire prediction area (As we would usually expect). I observe sharp differences especially towards the edges of the prediction area. - I tried to view the 4D prediction to confirm whether the models and transmitters are exactly identical. However, my ProMan hanged responding very very slowly. - I also tried to export results and compare, However the time variant simulation's ASCII file is huge (~700-800 MB). This could be because time variant model is exporting data for all time instances. Please advise if there is a way I can find out the reason for differences am observing between time variant and non time variant (exactly identical to time variant) ProMan simulations. One way to understand this is to find out if we can extract data only for the single time instant and/or if we can 3D view to compare the prediction plane (time variant and non time variant simulations) without ProMan hanging. Your help is highly appreciated. Thanks Balaji
  9. in my analysis I observed that, Time variant and non-time variant simulation results are not exactly identical (as we would usually expect) in the entire prediction area. I see sharp contrasts especially towards the edges of prediction area. I tried to view the prediction in 3D, however time variant 3D view is responding very very slow. I tried to export results and compare, however the time variant ASCII file is very huge (~700-800MB). It could be because time variant model Is exporting data for all time instances which I don't need. Please advise if there is a way I can extract data only for single time instant? Also, please advise if I can 3D view the time variant simulation result without hanging my ProMan. Please advise Thanks Balaji
  10. In continuation to the procedure explained above, The Edit window provides multiple options to superimpose the heat maps. for example, heat maps can be added, subtracted, multiplied and combined too with max value, min value and mean value as options within combine dialog.
  11. Dear reinerh, mvogel, my apologies, I stand corrected, in my previous comment above, I mentioned that both time variant and non time variant results look identical visually. However, those are not exactly identical in the entire prediction area. I see sharp contrasts especially towards the edges of prediction area. I tried to view the prediction in 3D, however time variant 3D view is responding very very slow. I tried to export results and compare, however the time variant ASCII file is very huge (~700-800MB). It could be because time variant model Is exporting data for all time instances which I don't need. Please advise if there is a way I can extract data only for single time instant? Also, please advise if I can 3D view the time variant simulation result without hanging my ProMan. Please advise Thanks Balaji
  12. Thanks a lot for your kind responses. I can visually interpret that the time variant and non time variant results are identical. However, I plan on exporting results into ASCII and re-compare. I sincerely appreciate your contribution towards my queries. Thanks Balaji
  13. Reposting in India specific forum. apologies for cross posting Hi all, I intend to compare the ProMan results of time variant simulation to those of the non time variant results for every time step. I want to do this to better understand the time variant simulation results. when I perform, Edit >> Subtract data >> Value (file, linear), I get the following error message. "The currently displayed data contains values at the following time steps 0.0000s, 1.0000s, 2.0000s, 3.0000s, 4.0000s, 5.0000s, 6.0000s, 7.0000s, 8.0000s, 9.0000s, 10.0000s, 11.0000s, 12.0000s, 13.0000s, 14.0000s. The data in the selected file contains values at the time step 0.0000s. Currently time step 1.0000s is displayed! but no matching time step found in selected file! Time steps do not match. No operation possible!" please help me compare the results Thanks Balaji
