    Or they are waiting for increased backhaul.

    Don’t forget that there will be 15x15 L1900 plus L2500 stacked on top of that 10x10 L750 carrier.

    They’re really moving everywhere. Lots of upgrades are happening all over and we’re seeing a lot of new small cells and macros entering permitting now too!

    That’s definitely progress! I’ll be on the lookout for it here in Seattle. On an unrelated note, B2/25 MFBI is live for Verizon and I’m hearing B5/26 MFBI is on its way. Interesting, interesting.

    Those antennas are B26/B41 antennas. In combination with the old NV antennas, they should be able to provide 4x4 L800, 4x4 L1900 and 8x8 L2500...it’s very strange you’re not picking up anything but L1900...
  6. RAvirani
    Has the phone stuck on B2 and we’re you able to pass data? Often phones scan bands and will appear to latch onto them for a few seconds although data will not work...
  7. RAvirani
    Still nothing. We’ve got two 1x1900 carriers and an EVDO carrier in the PCS B block as well as a 10x10 L1900 carrier spanning the PCS C5 and G blocks, although the PCS C4 block remains completely unused.

    So I picked up another two new L2500 carriers in downtown Seattle, bringing us up to a grand total of 8 carriers live across the region. Here’s what I’ve noticed: - Most 8T8Rs seem to be running five carriers (40072, 40270, 40978, 41176, 41374) - All mini-macro-on-macro sites are running two carriers (40978, 41176) - All magic boxes run one carrier (39874) - Most small cells/DAS setups seem to be running two carriers (40582, 40780) Pretty neat stuff!

    That’s s really bad photo...can you get a closer/higher res one?
  10. RAvirani
    Probably a mistake by SCP. I’d recommend you check your engineering screens because that data will be much more accurate.

    Do you know if the iPhone 8 supports 256QAM? I’ll go out and test my speeds today.
  12. RAvirani
    Yup—we’ve got tons of sites like this in Seattle. Most in downtown run 5 L2500 carriers plus 10x10 L1900 at 4x4 MIMO. And we’re getting 3x3 L800 (at 4x4 MIMO as well) pretty quickly too. It’s an exciting time for the Sprint network for sure!

    We’ll have to wait and see... A Verizon-like deal is possible too...

    Sprint equipment can serve 1900 MHz by itself, it’s just that T-Mobile doesn’t deploy any AWS equipment that is not also PCS capable. I totally agree that implementing CRAN would be a good move for the combined company. I know it’s been really good for AT&T in Seattle.
  15. RAvirani
    Yes, I did mean per sector, which is not too bad. Almost all Verizon setups in Seattle use 3-4 antennas per sector and almost all AT&T setups use 2-4. Since we are seeing 4x4 800 RRHs coming out soon, I’d guess most future deployments on 800/1900/2500 will only utilize 3 RRHs per sector. Additionally, T-Mobile heavily utilizes active antennas today (antennas with an RRU integrated), so that ought to help a lot too. I’d estimate a full joint T-Mobile and Sprint setup would only require 4-5 RRUs and 3 antennas per sector today. If we see 2100 integrated into T-Mobile 600/700 antennas in the future, we could get all 6 bands into 2 antennas and 4 RRUs per sectors — that’s pretty manageable if you ask me.
  16. RAvirani
    Three antennas per tower easily: Sprint 800/1900/2500, T-Mobile 600/700, T-Mobile 1900/2100. RRHs can be doubled up and reused across both network.
  17. RAvirani
    Do you have a link to a recording of the call or a transcript?
  18. RAvirani
    I don't really think that would be a smart idea... I think the ideal network configuration for a combined company would probably be: ~20x20 NR600 5x5 L700 5x5 L800 A single 1x800 carrier 20x20 L1900 A single U1900 carrier 20x20 L2100 LTE/NR on 2.5 GHz There isn't much benefit to shutting down 1x800 because not much else can be done with that 1.25 MHz FDD slice of spectrum. Additionally, 1x800 provides far greater range than LTE or NR will ever be capable of and would be very useful to keep for edge-of-cell rural cases.

    https://www.wsj.com/articles/sprint-t-mobile-boards-vote-to-approve-all-stock-merger-1525017644 Now we wait for the DoJ’s response.
  20. RAvirani
    PRLs do not affect LTE connectivity — they are only for CDMA. What you are observing must be a coincidence. As Sprint and Open Mobile are still integrating their networks, Band 13 will probably come and go quite a few more times before you’ll be able to properly connect to it. It’s hard to say. Although I may be wrong, I think that if the merger does goes through (which it may or may not), it will go through everywhere.
  21. RAvirani
    They don’t have to — they could just do what they’ve done with AT&T roaming: AT&T LTE for data and 1x fallback (on Verizon or some other regional provider) for voice.
  22. RAvirani
    If the site has B26 RRUs and a capable antenna, no site visit should be necessary to turn it on. Unless they’ve done something really dumb.
  23. RAvirani
    Most upgrades in the Seattle market are completely finished in a day. That being said, I have seen work in a tower drag on. for a few weeks.
  24. RAvirani
    That’s actually a perfect comparison — thanks!
  25. RAvirani
    Do you have the dimensions of this antenna by any chance? Or maybe a picture of it next to NV/next-gen equipment?
