    Is ATT (or any carrier) doing 5 CA (carrier aggregation)?

    On my SignalCheck Pro app it shows 5xCA: 10+15+15+5+5 Mhz. But in service mode it's not reflecting the same infoName:  Screenshot_20200316-223440_SignalCheck%20Pro.jpeg

    They most certainly are. I see it on all sites with bands capable of doing so. 4 mid and 1 low.

    Nice. I wonder why it didn't reflect that info in service mode?

    Yeah, have seen on both ATT and VZW.

    You'll see it activate if you run a speedtest.

    Personally I’m most looking forward to seeing mmWave used as supplementary downlink, because a sub-6 GHz uplink will be much more stable (especially once downlink mmWave uses massive MIMO to boost its range).

    Is Massive MIMO still a thing? I thought it was just some made up nonsense from Sprint. Kind of like WiMAX — also from Sprint — when LTE came out.

    Now that Sprint is dead, unless Qualcomm, Ericsson, Huawei, and Nokia embrace this technology (which I’ve not seen widely reported, but may have missed) I don’t see Massive MIMO taking off.

    But I could be wrong. Here are some recent PR pieces from Qualcomm and Nokia

    https://www.qualcomm.com/news/onq/20...le-experiences

    https://www.nokia.com/networks/solutions/massive-mimo/

    Still sounds very Sprint centric (Nokia/Samsung/Quality)

    But this article suggests that Verizon and AT&T might be interested too.

    https://www.lightreading.com/mobile/.../d/d-id/749504

    But given the added cost in equipment it seems like a technology which will likely be limited to ultra high density applications (stadiums / conference centers)

    Carriers are aggressively deploying 5G NR equipment now and it’s NOT of the Massive MIMO variety.

    That same article confirms Massive MIMO is, currently, a niche technology

    “Globally there are at least 87 projects that have involved testing Massive MIMO in the context of 5G, according to the Global Mobile Suppliers Association.”

    “Carriers have been installing Massive MIMO antennas on our towers for a while now. We have around two to three dozen sites where we have received -- and approved -- applications to install such antennas," said Vertical Bridge's Borghei.”

    “Thus, it appears that the rollout of Massive MIMO technology is taking the same kind of bumpy, circuitous route that many new technologies take -- it works in some places, some of the time, for some people, and for others it doesn't.”

    Even without massive MIMO, mmWave downlink is considerably more resilient than mmWave uplink.
