    Re: Beamforming antenna import in Atoll

    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...

    Re: [Download] GENEX OMStar and FMA

    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.

    Re: UL TBF Access Fail

    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...

    Re: Atoll DTM resolution

    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.

    Re: Atoll DTM resolution

    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.

    Re: DL 4x4MIMO is not working

    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...

    Re: DL 4x4MIMO is not working

    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...

    What you say about diversity is generally true, but has nothing to do with MIMO mode directly. For example if you have an 8T8R TD-LTE system (like we do), you can configure it as the following:

    Re: MIMO 2x2 to 4x4 Change

    To add to that, the fixed CRS overhead of your network will rise form 11-12% (2x2 MIMO) to almost 25%.

    In my opinion, 4x4 MIMO only worth it where:

    1. The amount of 4x4 capable UEs is high (at...
