    I think they might try to get 20x20 of contiguous PCS (possibly at the cost of some AWS spectrum) everywhere because that can be immediately deployed on all modern (600/700/1900/2100) and legacy (1900 only) T-Mobile sites as well as all Sprint sites.

    I began to notice this yesterday. Hopefully they’ll finish whatever they’re doing quickly—this lack or reliability is a bit disappointing.

    The new Sprint site on Microsoft building 43 is finally live with L1900. I have not been able to connect to L800 or L2500 yet, though, and CDMA does not appear to be live either…

    Oh sorry—I was looking at the rack above the Sprint rack. That appears to be a standard Sprint Ericsson setup.
  5. RAvirani
    Looks like a Verizon setup to me.
  6. RAvirani
    Yeah—that’s pretty exciting! No movement yet in Samsung and Alcatel Lucent markets yet, though, right?

    Do you have 256QAM live for downlink? If you have a phone with NSG, you can check MIMO information there... Is it live in the city as well?

    Nice find! What market is this in? On a related note, does anyone know if the iPhone 8/8+/X support UL CA?
  9. RAvirani
    Has anyone been able to use it yet?
  10. RAvirani
    Do you know who the manufacturer(s) is or how well they perform?
  11. RAvirani
    Does Sprint already have these 8-port antennas in stock?
  12. RAvirani
    Yes, their PCS spectrum is leased to GCI. Are we seeing any movement in the SMR band in Alaska?
  13. RAvirani
    This.
  14. RAvirani
    Are they adding PCS-capable equipment to these sites for CDMA? If so, why not fire up L1900 as well?
  15. RAvirani
    Hopefully that will be soon. I am very unimpressed by the 16-port antennas’ range and propagation.

    Why do they not run 3x3 L800 throughout border region 2? It seems bizzare to me that they change from 3x3 L800 to 1x800 at Rochester...

    That’s a bummer. Qualcomm chips are of noticeably higher quality than Intel chips. Apple just keeps falling farther and farther behind in the RF department...

    8T8Rs can only broadcast 3 carriers at 8x8 MIMO. Dual antennas/RRUs will allow them to broadcast up to 6 carriers at 8x8 MIMO. Physical split sectors are also a possibility although I don’t know if that’s something Sprint is actively pursuing...

    Future proofing. Since 800 is just now rolling out in the Seattle market, all sites are in the process of being upgraded, and all sites capable of supporting the weight are getting a hexadecaport antenna along with an 8T8R. Also, from my observations, in these setups, the 8T8R antenna is only actually hooked up to a radio about half the time. The other half of the time, the antenna is installed but remains inactive and radio-less (with L2500 only broadcasting from the hexadecaport antenna).
  20. RAvirani
    Yes. A higher-resolution picture is definitely needed to be sure.
  21. RAvirani
    Judging from the panel sizes, I’d guess it’s a hexadecaport alongside an 8T8R.
  22. RAvirani
    Very interesting. Does the device jump back to Sprint LTE when it is available? And if so, aggressively or not?
  23. RAvirani
    I believe this is what they are attempting. What PRL/carrier version are you on?
  24. RAvirani
    There are a lot of cases where wifi calling is not feasable—assume you have satellite home internet (and accordingly an unreliable ping), or your office’s enterprise network blocks VoIP, or wifi doesn’t reliable cover your house (because MBs provide much better coverage than a single wifi router/AP almost always). These are just a few of the many cases a MB is really useful.
  25. RAvirani
    Neville Ray has mentioned he will try to migrate people from L2500 to L2100 rapidly in order to make room for NR2500. The future of MBs will probably depend on whether 1-2 L2500 carriers are left live long term or not. If L2500 remains, I don’t see any reason why they would decommission already functional and working MBs—that would only upset customers who have one (which is a lot of customers).
