    The original triband antennas had significantly wider beamwidths. In my experience the increase in MIMO does not compensate for the lost coverage between sectors or at elevations drastically different from the elevation of the RAT center.
  2. RAvirani
    That’s very disappointing. Qualcomm modems are far superior to Intel modems of the same class.

    Sprint has been the fastest in Seattle for a while...but that’s a big speed jump!

    A while back Verizon roamed on Sprint in some parts of Texas although I don’t think this is the case anymore... Your phone was probably just scanning bands and happened to display B26 for a few seconds.
  5. RAvirani
    I think that’s a Sprint hexadecaport antenna.

    I think Boston is actually a Samsung market. My question was regarding to @nexgencpu‘s post.
  7. RAvirani
    Ah. What vendor region was this?

    Can anyone clarify what order QAM (both for downlink and uplink) the iPhone 8, 8+ and X support? Also, I believe the iPhone does not support UL CA, but was wondering if someone could clarify that for me as well?
  9. RAvirani
    Awesome to hear. Is 256QAM live yet for downloads?
  10. RAvirani
    Take a trip down to Seattle—I regularly see over 200 mbps down throughout the city .

    The iOS app does successfully log coverage—it just seems update the map quite slowly.
  12. RAvirani
    We’re you able to check if the modulation scheme as well? 64QAM for uploads would be really nice!
  13. RAvirani
    Oh awesome! I actually know which site that is—if I were still in Seattle, I’d definitely drive down and check it out.

    It’s 10x10+5x5 L1900 carrier aggregation.
  15. RAvirani
    Now that looks more interesting... I really wish Sprint would find a way to turn on CA such that L800 could be the PCC and L1900 could be the SCC. I can think of countless cases where the L1900 upload speeds are very slow, but download speeds would really give a boost to a UE that would otherwise only be connected to L800.
  16. RAvirani
    Yup—just realized I read it wrong.
  17. RAvirani
    Hold on is that B41/B25 CA?!
  18. RAvirani
    I have not seen anything yet, but I’m in a Samsung market. Maybe users on other Nokia/Ericsson markets can chime in?
  19. RAvirani
    I’ll take a look when I head over to my local Walgreens today! If only they could ink a deal with Target...

    The network needs a few weeks to optimize the macro-to-small-cell handoff. When small cells first come up, they are usually quite difficult to connect to, but the problem shouldn’t persist for very long.

    15x15 contiguous is not th same as 10x10+5x5. There is apparently a holdup with the Samsung equipment as well. They are running into errors in testing which they still have not resolved.
  22. RAvirani
    That’s because equipment isn’t yet certified for 15x15 operations. As soon a second it is, I’m sure Sprint will switch over to 15x15. I agree that what you’re saying would make sense in cases where Sprint has greater than 20 MHz FDD of contiguous spectrum. But I think those will be few and far between.
  23. RAvirani
    Sprint should not and will not split contiguous spectrum into multiple carriers. Performance is much worse—dozens of studies have been done regarding this.
  24. RAvirani
    Can you get a picture of these new panels?
  25. RAvirani
    You were roaming on AT&T LTE—no other provider really uses B30. The bars all being empty means that you weren’t connected to a network for voice (CDMA). For some reason it looks like you weren’t able to pick up either USCC or a regional carrier...
