  1. As I have stated over and over , devices with no volte current that was launched pre volte soft launch last fall will get it in a software release once the national launch occurs. Sent from my Pixel 3 using Tapatalk
  2. SIMOLW416TQ or 516TQ from the byod Sim kit Sent from my Pixel 3 using Tapatalk
  3. If that information is available, I'll have the spreadsheet updated this evening when I am off and back home. Sent from my Pixel 3 using Tapatalk
  4. Yeah they were definitely optimized for low mid bands plus they're much newer designs than most of the dual band NV hex ports. I wonder how the new octoports would compare in terms of low mid propagation... Sent from my Pixel 3 using Tapatalk
  5. I relay feeding Most likely an Airharmony 4400 that does 2t4r which goes into the 4 port sector antenna. Sent from my Pixel 3 using Tapatalk
  6. Strand mount small cells of the tmobile flavor. Supports LAA or LTE-U Sent from my Pixel 3 using Tapatalk
  7. Mixing and matching Samsung and Ericsson macro cells aren't always the smoothest things. Definitely work to do. Sent from my Pixel 3 using Tapatalk
  8. The formerly separate open mobile network is something to take into consideration as well. Sent from my Pixel 3 using Tapatalk
  9. Negatory. They're shorty antenna panels stacked on top of other. Sent from my Pixel 3 using Tapatalk
  10. Sprint has been purchasing roaming access to T-mobile sites for in market roaming. Helps them increase capacity and coverage for sprint users without resorting to building new cell sites. Sent from my Pixel 3 using Tapatalk
  11. The S8 was one of the Volte test devices that engineers were running around with for more than a year before the soft launch. The S9 were released a half a year before the soft launch and was not. Therefore it's considered an older device that predates volte while devices that came out after (2019) are considered newer devices which have volte Enabled out the box.

  12. It and most others were slated and actually prepared for VoLTE in January when the decision was made. It's funny because Google actually included the sprint IMS settings for sprint volte but sprint didn't block the Pixel 3s access capabilities. Hence why force enabling it works on all sprint eNBs (macro + A4/3/MB OG - Gen3). Sent from my Pixel 3 using Tapatalk
  13. 1- should be at least on par with the more common rfs/ commscope ones they use. I'm not too sure about the JMA ones though. Supposedly they're ridiculously good which is why Verizon has been replacing older sets with those non stop. 2. Woops typo. I should've said same antenna model series. Its 8 low band ports.

  14. Do not just zoom in on one device. Sprint stopped the volte updates for ALL older devices in mid December after the iphones and LG v30. They will start releasing those after the full national launch which is not far from now. Sent from my Pixel 3 using Tapatalk
  15. In terms of radios, Ericsson actually has the most modern radios for 1.9 as the NV RRUS11s were ripped out literally right after they were installed. Penalties for doing a shit job in NV.... It's the same generation as the RRUS32s the other three are still deploying to this day which are very good designs. Antenna wise you do have a point. I've seen ATT and VZW swap out their antennas for newer high gain and performance ones thrice already (LTE B12/13 --> B2/4 --> B5/14/29/66/71 etc) At the bright side they're being very proactive in many regions and going back and changing them to brand new RFS / KMW / etc 8 port antennas that add 4T4R 800 MHz capability while increasing 1.9 coverage patterns / range. My home Clear NV site 800/1.9 antenna was turned on a few days ago and I've been very impressed at its coverage pattern at a 40' elevation. Newer antennas can make a lot of difference! (10-20% perf improvements in same cases) Edit: I've seen pics of those new T-mobile low band antennas. They're the same octoport low band model series from RFS that Sprint is now using.
  16. I mean for a lot of urban areas it's still not going to be available til 2020-2021. Time sure did fly by though. We're past the halfway point of 2019 already!!! It feels like it was just yesterday when I first began looking at my local cell sites in 2012 waiting for NV to begin. Sent from my Pixel 3 using Tapatalk
  17. First two digits indicate region code, next two is cascade 4 is site type with the last three being unique site identifier. So something such as SF72XC would be a northern California cell site macro class. Something like SF90XS would be a northern California small cell mini macro site. XC is macro, XS usually denotes small cell. XR is repeater. XM is microwave. Xt is toy cell (internal usage). XD is DAS. Sent from my Pixel 3 using Tapatalk
  18. B46 is LAA unlicensed LTE on 5 GHz. I believe LTE-U is as well (Band 252? or around there). As far as I can see it's mostly 1 PCC of FDD type + multiple LAA carriers. The newest specs for it has 1 lowband PCC + 1 midband SCC + SCC LAA's. There is no B66-2-46 standard config i can find at glance but feel free to find it and let me know.
  19. FDD-TDD limitations due to different radio technologies. Samsung phones has the most advanced radio configs and thus supports the most carriers but have limitations on MIMO streams as in no 4x4 MIMO on any component carriers. Most other devices are FDD+TDD and some are FDD+TDD+TDD but again there are limitations on MIMO streams. Most of Sprints 1.9 network has 4x4 or 2x4 now live and a large portion on 2.5 is 4x4 so that's a chunk of downlink capacity being traded off. It's a large balancing act and with the turnaround inside of Sprint and with the rudderless leadership, we can see why many projects do not come to fruition. FWIW, FDD+TDD was identified early in the industry on as one potential solution to slow uplink speeds years ago alongside uplink CA using higher order MIMO. It is not the end all solution but a very useful tool in the toolkit if they can figure out how to use it.
  20. Sprint calls in Ericsson for site work ==> Ericsson assigns available local peons of varying quality to work ==> some time later ==> Ericsson worker arrives on site ==> worker connects to Ericsson employees in India to do the actual work ==> worker verifies work is "done" and calls it a day ==> tells sprint all good. TLDR of Ericssons network management work. TLDR2: Remember the 65 MHz PCS project? Ericsson completely ripped out the entire PCS NV ERC network in 2014+ for brand new radios for basically free while ALU and Samsung NV era PCS radios are still in use.

  21. Yep! You're going to see a lot of them. Lots of carriers now upgrading to these units to support 4x4/2 low band configurations! Sent from my Pixel 3 using Tapatalk
  22. Not really. It's the same type octoport (not same model) with 2x800 radios + 2x1.9 (plus RF combiner) feeding it. Sent from my Pixel 3 using Tapatalk
