Dual Band MIMO deployment


Recommended Posts

It makes a lot more sense if this is basically warranty service being provided by Ericsson. I was operating under the impression that Sprint was paying for the swap when it would have been a much better investment to deploy band 41 and then worry about upgrading the band 25 equipment later.

So they have 2 antennas and are still running at least one in dual mode? Or are you referring to if they decide to add a second antenna to all sites for this? I would assume all high capacity sites have one antenna that's just LTE (and 4x2 MIMO) and another that's just CDMA?

Wait if they have two antennas, couldn't they run one on 1x/3G only and 4x2 MIMO LTE 1900 from the other?

With the upgrade, the new Ericsson radios are far superior and can broadcast at a higher power. Also, this will allow 4x2 MIMO. So really, this isn't so much about added CDMA capacity, it's just one benefit.

 

The first generation Ericsson NV radios were crap. Ericsson is basically having to switch them out free of charge. All this is bonus for Sprint to do this switch. The only thing is it should have been done this way from the beginning. So I'm not sure why people are against this.

Will early adopters of LTE like Houston (that do not have spare spectrum for additional CDMA/LTE carriers) also see these radio replacements?

Yup.

    • The S21U was very spotty with connecting to 6E. It would only see it on a router reboot. I thought it was more the router than the S21U, however my laptop would solidly connect to the 6E network, so it must have been the S21U. Since I'm on WiFi7 with the S24U, I haven't kept track of it. I will flip over and check it out later. 
    • Wi-fi 6e missing (6 GHz on one of two ultras). Perhaps coming from an app?  Wifi analyzer can see the 6ghz, just can't see them to connect.  May try wifi reset, although communications reset could have been the source of this problem.  Others have reported it, so not an isolated issue. Edit: Fixed: Rebooted into safe mode. Wifi 6e worked. Normal boot back. No wifi 6e in available nerworks.  Unistalled Asus Router app. Checked for Wifi 6e being visible in wifi available networks. Nothing. Deleted Netgear Genie app. Then saw networks. of mine I had not connected to in wifi available networks. Forgot the desired 2.4&5&6 SSID that did not show 6E. Connected to it again. 6e now works.
    • I noticed today while I was out and about in Louisville that b30 has been widened back to 10x10. They reduced it to 5x5 back in Sept 2018 presumably due to satellite radio interference. Not sure how long ago the change happened but it couldn't have been too terribly long ago. I noticed the different earfcn in the neighbor list, I don't usually see b30 as pcc much but I wonder if that will change now. I locked my phone to b30 only on my drive home from work and noticed the new(old?) earfcn on every site, so it wasn't just a 1 or 2 site fluke. It also looks like they've been doing some fiber or other cabling work around the b2/b46 small cell nodes, I wonder if they are about to start adding c-band radios to those. 
    • Should trade it for some low-band there or elsewhere. AT&T dominates lowband.
