  1. No. Massive MIMO panels are significantly smaller than those and do not have separate radios. That looks like Verizon equipment.
  2. Permitting to swap from 8T8Rs to M-MIMO antennas is surprisingly easy. On many sites in my market, Sprint replaced the 1900-only antenna with a hexadecaport and left the 8T8R antenna unconnected to an RRU. This is so that they can easily one-to-one swap that antenna for a M-MIMO antenna when they're ready.
  3. There are many cases where L2500 or L1900 signal is too weak to provide a reliable uplink, even though downlink still works well. In these cases, instead of placing users on L800, wouldn't it be convenient if L1900 or L2500 could be primarily used for downlink while L800 was used for uplink? This would save L800 capacity for real edge-of-cell scenarios where L800 is the only available LTE network. I don't think L800 should be aggregated with other carriers in areas with strong signal strength, though. This would be unnecessarily wasting the little capacity it can provide. A setup where L800 could be the PCC but not an SCC would be ideal.
  4. How is signal propagation compared to before and other bands now?
  5. Yes, I've seen Band 7 bear the Canadian border. EARFCNs are between 2750 and 3450.
  6. E-UTRA stands for Evolved UMTS Terrestrial Radio Access. It is just the LTE air interface. An E-UTRA neighbor is just a neighbor LTE cell/sector that your phone is measuring (possibly for cell reselection).
  7. It's likely Field Test just being buggy as usual.
  8. Any device with an ISIM can be updated with an IMS profile for VoLTE.
  9. I'm headed back home in a week. I'll definitely be able to get high resolution photos of the new 8 port dualband antennas. Some of them might have C4s.
