PedroDaGr8 Posted October 20, 2020 Share Posted October 20, 2020 Found a third n41 along that same powerline. A new T-Mobile B41/n41 signal has appeared at the 405/522 interchange. I discovered that the powerline tower at 47.7798189, -122.1750665 has been upgraded to B41/n41. It is broadcasting 40MHz of B41 and 60MHz of n41. I was able to pull around 400 Mbps from it when I was close by. 1 Quote Link to comment Share on other sites More sharing options...

Sent from my SM-N986U using Tapatalk After over a month, they finally turned on n41 on this tower. Previously I could connect to B41 but could never get an n41 signal. 1 Quote Link to comment Share on other sites More sharing options...
PedroDaGr8 Posted November 6, 2020 Share Posted November 6, 2020 Some more towers have been moved over to 1910/1990 for B25 this morning. I am starting to wonder if the towers on 1910/1990 are ones which will potentially be kept. It seems like at this point, the only ones left on 1907.5/1987.5 are towers which will obviously not be kept. 1 Quote Link to comment Share on other sites More sharing options...

RAvirani Posted November 10, 2020 Share Posted November 10, 2020 Some network updates in downtown Bellevue: SE03312B on top of Greg's Bicycle is broadcasting 2500. This will be a huge capacity boost for T-Mobile around Lincoln Square/Bellevue Square Mall. New build SE03939D on top of Centre 425 is also live with everything except 2500 (as the permits for this site were submitted before the merger). New build SE03338I on top of the North Civica building has been built (similarly with everything except 2500) and is currently undergoing call testing. OA is expected late this month. 1 Quote Link to comment Share on other sites More sharing options...

No backhaul upgrade yet, though. 1 1 Quote Link to comment Share on other sites More sharing options...

Went by there today and was able to connect. Has anyone seen the 312-250 PLMN in the metro Seattle area? I see that one tower was broadcasting it out by Port Orchard, WA but nothing else in the state. Quote Link to comment Share on other sites More sharing options...

You'll be able to catch it at Westwood Village shopping center in West Seattle. The Sprint site in Startup as well as the Sprint site at Snowqualmie Pass are some other examples of 312-250 sites. 3 Quote Link to comment Share on other sites More sharing options...

T-Mobile expanded from 10x10 to 15x15 here, but they were using existing T-Mobile spectrum. Sits right next to the G Block, but don't expect them to take that over any time soon.

It would allow a PCS C+G carrier to be simultaneously broadcasted as a 15x15 B2 C carrier and a 20x20 B25 C+G carrier based on device compatibility. 4 Quote Link to comment Share on other sites More sharing options...

That's Multiple Frequency Band Indicator (MFBI) and has been a part of the LTE spec since 2015. https://www.phonescoop.com/glossary/term.php?gid=551 Sounds like it will be primarily a 20x20 B25 carrier broadcasting a 15x15 B2 MFBI so that older or foreign devices that lack B25 support will be able to use part of the spectrum. I bet they'll do this in all markets where they have contiguous C+G holdings. 2 Quote Link to comment Share on other sites More sharing options...

I bet they'll do this in all markets where they have contiguous C+G holdings. The MFBI spec does not support simultaneously different IBWs/center frequencies. For example: 15x15 C block carrier could be simultaneously broadcasted as B2 (1125) and B25 (8565) with MFBI. However, MFBI does not support simultaneous broadcast of 15x15 B2 (EARFCN 1125 in the PCS C block) and 20x20 B25 (EARFCN 8590 in the PCS C+G block) that overlap by 15 MHz. Achieving the latter is a much more complex problem due to the fact that guard bands would be of different widths and thus, the physical resource blocks and LTE subcarriers wouldn't necessarily line up. These challenges require careful timing, real-time PRB blanking, dynamically served handoff parameters, etc. to solve. 2 Quote Link to comment Share on other sites More sharing options...

So far, confirmed in Bellevue, Bothell, Kingsgate, Kirkland, Lynnwood, Shoreline, and Woodinville. The user in Shoreline is reporting notably better signal overnight as well (from 1 bar to 3-4 bars). 1 Quote Link to comment Share on other sites More sharing options...
PedroDaGr8 Posted December 14, 2020 Share Posted December 14, 2020 The site in downtown Juanita Beach is now equipped with n41. It's got a pretty good backhaul, I was able to hit around 470 down (n41+B2+B66). 1 Quote Link to comment Share on other sites More sharing options...
