  1. 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
  2. The formerly separate open mobile network is something to take into consideration as well. Sent from my Pixel 3 using Tapatalk
  3. Negatory. They're shorty antenna panels stacked on top of other. Sent from my Pixel 3 using Tapatalk
  4. 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
  5. 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.

  6. 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
  7. 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.

  8. 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
  9. 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.
  10. 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
  11. 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
  12. 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.
  13. 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.
  14. 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.

  15. 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
  16. 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
  17. If it doesn't get a WAN green light then it's likely a faulty unit. Get a replacement on that case. Sent from my Pixel 3 using Tapatalk
  18. Verizon is / was deploying the Ericsson 5GTF backend systems which is their proprietary 5G pre NR standards setup. The M-mimo equipment on cell towers / light poles are dual mode 5GTF and NR capable. So it's fairly simple for them to just "flip the switch" (simple terms). They had built a completely new standalone system for 5GTF that doesn't really interact with their extensive LTE EPC hence why they can go full stack NR rather than mixed which most carriers will be going with.

  19. Typically Antenna size restrictions. I've seen a few of them in socal where they used a 4' midband and a 4' lowband to satisfy regulations. Sent from my Pixel 3 using Tapatalk
  20. Only Sprint uses these type of All in one mini macros. You'll predominately find standalone mini macro on macro setups as part of Clearwire site replacements since it's a cheap drop in replacement.
  21. Unfortunately They are currently actively building out a spectrum protection network to meet build it requirements.......... Sent from my Pixel 3 using Tapatalk
  22. Buy it at the price they wanted. The whole calculus has changed since 2018 when Softbank has shown its hand on how desperate they want to offload Sprint. There's many sharks swimming around the bleeding body that is Sprint ready to snap at the right moment which would be post merger failure and devaluation of the Sprint stock pricing and credit rating.

  23. Got the PM. Responded with a one request but I''ll be forwarding yours and another individuals S/N and status to the relevant folks to troubleshoot in a bit.
