  1. T-Mobiles 5G requires a lower frequency carrier along with the 2.5Ghz channel(s), though they plan to release standalone 5G in the future. Tmobiles 5G is supposedly more efficient than sprints too. Sent from my LG-LS998 using Tapatalk
  2. Came across a strange small cell broadcasting on only low B41 EARCFNs. It's on top of the Overlake Sprint store in Redmond. At first I thought it was the tower right behind the store but that has the usual tri-band setup (which used to be on the Sears nearby). I nearly missed this antenna, it's a small white fully enclosed small sell. You have to be far from the sprint store to see it. It only has these two cells unlike the old clearwire sites. Not the first time I've seen these EARFCNs, they seem to be used a lot in the Georgetown district. Edit: Checking back, most of those in the Georgetown district are also small cells but at least one is on a regular tower. Not sure why the Georgetown district has so many of these.

  3. Actually more than that since Sprint/T-Mobile controls the entire 2.5Ghz block (all 194Mhz) for the entire metro Seattle region. This allows them to use the J and K guard bands as well, since they control the blocks around them in their entirety. The K guard band (2614-2618) in particular was why the B41 20Mhz channels started at 2628MHz (until yesterday). As such, that would leave 130MHz for 5G communication if they wanted. Relevant License Links: B413 - TDI Acquisition Sub, LLC (shell company of Clearwire) L000002361 - Clearwire Spectrum Holdings II (shell company of Clearwire) L000007381 - Clearwire Spectrum Holdings III (shell company of Clearwire) L000007382 - Clearwire Spectrum Holdings III (shell company of Clearwire) L000007383 - Clearwire Spectrum Holdings III (shell company of Clearwire) L000031135 - American Telecasting of Seattle - Sprint acquired this spectrum in 2018.
  4. That gives them 100-120Mhz for NR based on my estimates. Sent from my LG-LS998 using Tapatalk
  5. Since the T-Mobile version already supports B25/B26/B41 as well as the usual T-Mobile bands including 5G, I imagine they didn't need to resubmit to the FCC. It wouldn't surprise me if they don't even switch out the boot screen.
  6. I looked through a bunch of permits and they use a variety of antennas over the years. The most common in recent years are the Commscope FFHH-65C-R3, Commscope SBNHH-1D65B, and Nokia AAFIA. Usually, the Comscope FFHH and Nokia AAFIA are used together. I included the ones I encountered in some quick searches below. I have also included links to pages or pdfs which show the antenna. Commscope: TMZXX-6516-A2M - 2 port: 1710-2155MHz (B2, B4, B66?) HBXX-6517DS-A2M - 4 port: 1710-2180MHz (B2, B4, B66?) SBNHH-1D65C - 6-port: 2x 698-896Mhz (B5, B12) and 1695-2360Mhz (B2, B4, B66) FFHH-65C-R3 - 8-port: 4x 617-806Mhz (B12, B71) and 4x 1695-2460Mhz (B2, B4, B66) Nokia: AAFIA - 16T16R - B25 and B66
  7. A quick hint, if your city has an online permit portal: If there are multiple towers in a small area, online permits are a great way to figure out exactly which tower is the for which company. I use that often to cross-check towers I believe are correct.
  8. You don't define cheap, but the LG v30 and v40 work well, can be rooted, and can be found for pretty cheap(<$100-150). As expected, the v30 is cheaper than the v40 and I can attest the v30 works very well. That being said, it lacks bands 28, 40, and 71 and has the drawback that Sprint never released Pie for it (the only vendor who didn't). This means some of the 9.0 bandwidth features are not available for SCP, that being said NSG is able to provide this data on 8.0. Sprint LG V30+ (LS998) LTE Bands: 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 20, 25, 26, 41 Sprint Lg V40 (LM-V405UA) LTE Bands: 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 20, 25, 26, 28, 40, 41, 71
  9. You can move them in the app as by long pressing on the tower and dragging it to it's new location. Sent from my LG-LS998 using Tapatalk
  10. I tooed my phone (LG V30+) this weekend and I noticed that the ##data# screen now shows "Enable All" instead of the weird letter salad which it showed previously. Not sure what this means exactly but at least now I can use NetworkSignalGuru. On that note, it confirmed what everyone else stated which was the B25 was 15x15. As for the other details, it appears to also be max 64QAMx64QAM and 2x2 MIMO which is pretty impressive because the numbers I was getting were near the theoretical limit for that combination (112.5/56.3 and I got 112/42.3).

  11. A couple of comments: 1. In the PNW, Sprint roaming on T-Mobile as Sprint still shows up as Clearwire B2, B4, B12 2. Not sure if you are tracking EARFCNs but D/L EARFCN 8615 is B25 15x15 according to this post.
  12. Yeah 15x15 sounds about right. Checking ##DATA#, my phone has 256WAM/64QAM enabled and 4x4 MIMO enable for both B25 and B41
  13. Seems T-Mobile uncapped the u/l on B25. I have never encountered this level of u/l speeds on any band. 5Mhz B25 (256QAM, 4x4 MIMO maybe?) D/L: EARFCN: 8615 (1987.5Mhz) - 112Mbps U/L: EARFCN: 26615 (1907.5) - 42.3 Mbps Previously, in this exact location, I would get Sent from my LG-LS998 using Tapatalk
  14. I noticed on my phone that T-Mobile has reordered the band priority moving B41 from second to third. Previously it went B25->B41->B26; now it goes B25->B26->B41. This explains why I have been connecting to B26 a LOT more often than I used to. My guess is this is part of the preliminary steps to phase out B41.
  15. I had been wondering who used this antenna. They are very distinct compared to the other antennas used. There are a number of them in the Kirkland area and I kept forgetting to ask. Sent from my LG-LS998 using Tapatalk
