      I'm new to this forum, and I've seen people mention cell sites with specific ID's (for example, SF33XC664). Is there any significance to these ID's, and is there a way to decode them? Also, how do I figure out what the cell site ID's are for towers near me?
      Thanks! I'm excited to start talking on this site more¬†ūüėÄ

      Hi guys,
      like the title says, I am travelling to the Netherlands and am curious about people's experience with the international roaming passes. 
      Firstly, are they unlimited data, or are they limited with deprioritization?
      Secondly, what are the speeds like?
      I have asked around but have gotten mixed answers.
      Thanks!

      I figured since Verizon's 5G-NR network officially launched it would make sense for there to be a thread for it.

      Samsung Network Vision equipment are highly distinct and fairly easy to spot compared to the equipment that other vendors are deploying. Sprint is Samsung's first extremely massive American contract (baring Clearwire) so there  should be no issues in confusing these equipment for another carrier which happens often with Ericsson NV equipment.

      Below are images of Samsung equipment which includes antennas, remote radio units, base stations, and their mounting configurations.

    • You obviously didn't see my second screen shot. Also M-MIMO has been great with cell edge performance especially on uploads.
    • But he posted a second screenshot that showed that his upload speeds were consistently around 20Mbps no matter the time of day while his download speeds fluctuated a lot more.
    • Like I said, anecdotal. All of those speeds tests where done in the span of 10 minutes past midnight, in (which is safe to assume) the same location and with extremely great signal strength/LOS. The problem with upload speeds in the 2.5 Ghz band is that the UL speeds dramatically fall off whenever you move away from the tower. Good speeds are possible, but on a few select areas near towers.
    • If your talking the Adjust LT timing Advance, no it's not on. I will give you some samples over the next few days.
    • Do you have the TA correction option enabled under Preferences? What I really need to do is get a decent sample size of B41 TA reports without the correction factor enabled, and record what the app shows and what the correct distance is. That would allow me to calculate what the proper correction value would be. TA is a funny beast on TD-LTE, I have always had a correction factor applied to the raw value.. so with the option enabled it's applying a correction to the correction..¬†ūü§Į
