I am really curious how to do this. And I have no doubt that others are interested in it as well.
The AAU is 32T32R, which has 8 columns of 12 cross polarized elements, which adds up to 96 cross polarized, 192 total antenna elements. Each antenna column has two independent RF channels.

Hi Slava,
I much appreciate your help, but I cannot create 3D beamforming antenna with the limited data I have about the AAU. I only have broadcast beam patterns, no traffic beam patterns.
...
Can you elaborate on how and where to do that? This is TD-LTE not NR by the way, but from a broadcast beam coverage point of view, that should not matter. I am using Atoll 3.4.0 15641
In regards...
Interesting: changing the "Number of antenna ports" from 2x2 to 4x4 under Transmitter tab does increase the RSRP DL coverage prediction (as expected), but changing it from 4x4 to 8x8 or from 8x8 to...
This is the one I want to use.
The problem is the underlying config: the cell is 32T32R, CRS2 (2x2 MIMO), and it is totally unclear in Atoll, where to set which parameter.
The "number of...
Just to keep this topic afloat: the "3D Beamforming Antennas" section of the Atoll manual does not contain any useful information about how to import a massive mimo antenna... The whole 1300 page...
Would you care to share it please?
I am also trying to import a Huawei AAU but there are a lot of unclear things.
I have the broadcast beam file, but under conventional BF antenna the max...
Can someone please share an up to date version of the Hedex Lite app? Mine (from 2017.) produces weird issues with latest hdx files. Thanks in advance!
Thanks, much appreciate your help!
Do you happen to have access to the SW as well?
I am looking for the latest SW and product documentation for Huawei OLT SmartAX MA5600T:
V800R018C10 (as much as I was able to find out V800R018C10SPC200 seems to be the latest version):
...
Well that is no true, V500R017 has 9.3.0 PostgreSQL, while 6.5.0 has version 11, and the installation of Postgres 11 is where the install usually fails.
Will dig in when I have a bit more time.
I tried to install 6.5.0 with the complete uninstall of previous OMStar, but I always got "Database corrupted please try to reinstall" message, and during install there is a clear problem with...
Yes. A single uplink timeslot can only be split 8 times, and this is not going to be shown as a PDTCH issue. You should have KPI(s) for UL TBF separately. The "other" casue is not very helpful for...
No. If you have UL TBF issues, that is not necessarily related to PDTCH issues. A single timeslot can be divided into 8 times max if my memory servers me good enough. If you have more UL TBF requests...
And you are sure you dont have a UL TBF exhaust scenario? Lately with a lot of networks removing 3G and shrinking 2G capacities, on GPRS/EDGE you will see UL TBF exhaust scenarios, even when the...
Yes, 1 meter is the lowest with this method. 0.9, 0.5, 0.1 meters are all fail to load to Atoll.
I am already at 1 meter resolution, why would I try 5 meters? Question is how to go below 1 meter so that Atoll accepts it.
The LiDar scan is in TIF format, that is imported into Global Mapper. Then it is exported from Global Mapper in Vertical Mapper Grid file (GRD), which is imported to Atoll.
This phone does not support 4x4 on band 20 or 28 for sure.
Non the less, the fact the modem is Cat4, that does not mean it cannot have 4 receive chains. It can, but not for MIMO (spatial...
The diff is huge. The original DTM is 490MB, the output is 64MB. Same exact area. The input is a TIF file.
If I lower the Sample Spacing in GlobalMapper from the current 1 meter to 0.5 meters, the...
Hi,
I am using this guide to create maps for Atoll: https://tholeibrahim.wordpress.com/2012/08/01/using-earth-explorer-digital-map-for-coverage-prediction-in-atoll/
Works flawlessly, the only...
I have not seen a single UE that has 4x4 below band 3. Sub-1GHZ is definitely 2x2, but on the RAN side it is similar. Even the dual or triple-band RRUs (ZTE for example) has 4 RX, but only 2 TX per...
I managed to get the portable version (Atoll.Std.x64.3.4.0.15641.MxBNET.Portable), but it gives a "sx32w.dll" error message popup. The recommended "AccessDatabaseEngine_X64" is already installed.

Based on the RRU/Antenna used, you can enable Rx diversity and IRC. Both of them are licensed in our case, not sure whats with Nokia in that regard. A more advanced version of IRC is something called...
