On another note, it appears that T-Mobile upgraded backhaul on my home site. Over the last few months, specifically post-iPhone 13 launch, I watched speeds on my home site decline a little. I went from hitting 600/100 regularly to seeing speed of 575/80 at all hours of the day. But this week I noticed that speeds are back up again. I just ran a speed test and got 660 down and 120 up on my site. LTE quickly shoots up to 220 Mbps but flattens out at 180Mbps.

I don't think its a backhaul upgrade; I think they have either adjusted the routing of data, or network optimizations. Same thing happened to me; -120 n41 + -118 B66 was <=150 down and 5 up a few months ago, and now its 230 down and 8 up. Tested the site at 5am last week, and it was gig cap which I found out since it got n41 late 2020. Haven't tested LTE in a while though, so I don't know how good/bad that is, but I would assume its pretty good since it has a 3246 on it.

Went up to Middletown again and found two keep sites. 

1. Sprint eNB 6325 (Location: 41.4311701118526, -74.35960489915462)
2. Sprint eNB 6324 (Location: 41.47101083500609, -74.37163722479815)

Also Sprint eNB 75141 in Staten Island is broadcasting the keep PLMN.

Add them all. I also adjusted the default map view so its easier to reach the ones in Middletown, since its quite a way north.

T-Mobile eNB 40982 is a flagpole site in Canarsie that apparently recently got n71 added to it according to Cellmapper. I'm wondering if n41 was also added and also how they managed to add other bands to it given that the current n71 antennas are a bit larger both in length and width than existing Band 12 antennas. It may give a bit of insight into how they plan to handle flagpole upgrades in the metro area and signal that T-Mobile may begin upgrading them in mass. I'll try to visit this weekend to take some pics of it.

Sprint eNB 73954 nearby, the one which @thisischuck01 found, has been converted. I would assume some of the other sites in Canarsie have been upgraded, but the towers aren't passed by often enough to update them.

I still have some 312-250 data to add to the map, as I have finished looking for 8xxxxx eNBs, I'll summarize the changes when I finish.

Found another mmWave small cell, again outside of the specs the city approved. This time in Brooklyn, corner of Winthrop Street and Albany Avenue.

My guess is it's a B48-capable AIR 6449 variant deployed in the Bronx (similar to this deployment), not C-Band.

I agree, and like you said in the comments on the post, T-Mobile's C-band doesn't open up until Dec 2023, and they said they want to do a "one and done" rollout with C-band and 3.45 GHz, so this probably an updated CBRS panel. Some folks have already ran with it as T-Mobile installing C-band though...

Pretty sure eNB 895044 in the Bronx is a fully converted Sprint site. I'll confirm this weekend but I've marked it on Cellmapper already and the trails look correct.

Location: 40.82639148703134, -73.84100143796987

Added! T-Mobile seems to have a knack for poor Home Depot coverage that Sprint sites are filling in now wonderfully. I haven't been to the Bed-Stuy Home Depot recently to check if the Sprint site is being kept, as that one also has poor indoor coverage from T-Mo which the Sprint site fills in.

Sprint eNB 5820 is switched to Converted on the map. This time, I can confirm there is a Sprint panel left up on one of the sectors, but besides that, full rip and replace. Sprint eNB 6786 is still rocking its AAHF, so it hasn't been touched yet.

I'm not the only one who has added data across NYC to the 312-250 PLMN across NYC, so I'm taking another glance across the city for 8xxxxx eNBs and checking what can be added to the map from the 312-250 data.

Going through the data that I mapped, I found plenty of convert sites.

T-Mobile eNBs 894574/894577 are from a convert site, located at 643 Cauldwell Avenue.

T-Mobile eNBs 895003/895005/895006 are definitely from a convert site, but I only mapped one sector. I think its the 1116 Tinton Avenue Sprint site, but it needs more data.

T-Mobile eNBs 889284/889288/899289 are from Sprint eNB 75262. The city's streetview car caught it in August 2021. 

T-Mobile eNBs 895031/895032 are most likely from the Sprint site on top of 1501 Allerton Avenue. RSRP is quite low, so I doubt it's anywhere else.

T-Mobile eNBs 895008/895011 I think are from the site at 719 East 233rd Street, but it needs more data.

T-Mobile eNBs 894570/894572/894573 are most likely from the site on top of 2750 Olinville Avenue. The Google streetview car seems to have caught it in November 2021, but I'm not 100% sure about it. The 2nd panel from the right looks like a 6449. I realize my devices made a mess of the cells, so the data up isn't helpful. I think the location that oldsoulbenny located those Sprint eNBs is an AT&T site, not Sprint. Really weird uptilt on this sector, sometime in between August and October 2019 the change was made.

Something is strange about Sprint eNB 838411. The train was moving when my J5 roamed onto it, so I screenshotted Cellmapper as by the time I went to service mode, the device handed off. I'm not 100% sure its a 312-250 macro/small cell, but if it is being kept, its using the same spectrum T-Mobile towers are using for LTE, which usually doesn't happen. I have held off on adding a pin for it, as I need more data for it first.

--

In the Bronx, I think I found 3 sites where B41 was on 311-940 instead of 310-120. The Cell organization is totally different from the usual on 310-120, so that's fun.

The small cell in front of eNB 894588 is still live, quite amusing to watch my device flip between the tower and the small cell to anchor n41. It has been 2 months since the converted site has gone live, no need to shut down the small cell yet, it still serves a valid purpose lol.

I'll need to double check, but B2 seems to be widened to 20 MHz on the subway DAS at one station, 125th St/Lex (4,5,6 trains).

Verizon eNB 81005 has a small little panel next to its C-band panel, anyone have an idea what it is for?

There's a T-Mobile site on the building, DOB Job #320012008. Hard to link to the old DOB permit site but here's the job description:

"CREATING TELECOMMUNICATIONS ROOM WITH RELATED HVAC ON 1ST FLR AND CONDENSER ON ROOF RELATED ANTENNAS MOUNTED TO FACADE OF BUILDING"

Ah, it's in the facade of the building, thanks! I'll leave it alone.

I think this might be a leftover Sprint antenna? Hard to tell but it kinda looks like what was there the last time Streetview rolled through.

Definitely a possibility, you said the same thing for a picture of eNB 894640. Both sites have all bands expect 41 under 1 eNB, so it is probably a pattern.

Surprised to see T-Mobile decided to invest in deploying the spectrum! Pull any good speeds or are they all backhaul limited?

I don't have a CBRS capable device, so I don't know how the speeds are. I spotted the panel from the window of the bus, and a quick Google street view scan made me realize it was a neighborhood buildout, as if you go too far north or south the towers don't have the panel, only the 6449. I would expect 1G+ backhaul, as the tower in Manhattan with CBRS is a 1G+ site, but I have no idea.

Seems like he's seeing:

B2+B66 +n41+n41
n71+n41

While the article was updated to say Segan didn't find n41+n41 only n71+n41, I think T-Mobile has it planned anyway, as I found 20 MHz n41 in Brooklyn. I was looking for where eNBs 891645/891646 are to locate them, and stumbled upon on it. Didn't have enough time to circle back and find out where it is coming from, as the PCI matches the B41 cell found on 891646. What I find strange though is why they would do 80+20 when they could do 100+20 while Sprint B41 is still active along with their own B41. Probably will have to wait until June for 100 MHz n41.

--

For eNB 41177, I passed by the area and I didn't see any panels on top of the buildings, so I restored its location, but its been located back. Is there something I'm missing? T-Mobile has blanketed the area with small cells, and I think this eNB is part of it, but don't have enough data to be certain.

Starrett City

T-Mobile has had fun in Starrett City. Not only are all sites upgraded with n41, they also converted a Sprint site there. From the north going south:

eNB 49434 not only got the full setup, but they also added an AIR 3246 to the site.

New convert site: eNB 875360. I was excepting this once I first saw it, especially since Sprint eNB 73854 over in Canarsie is being kept. Not sure what the 4th panel is, and I don't think the pic I took is helpful.

One more site confirmed from the map, eNB 894967 located at 40.6817830451255, -73.90405504592015

Looks like Google Street View last drove by in December 2021 and it's all T-Mobile gear now.

I went and visited this site, and the downtilt is extreme for the 6449 panel on the 3rd sector that the Google car didn't catch. I'm surprised they even did a 3rd sector, with how close the site is to the others nearby.

I took a trip up to the Bronx and added a few towers/splits to the map. I still haven't fully gone through all the data I added yet, but I know I found a few convert sites. Also, if anyone is looking for T-Mobile CBRS to speedtest/check out, the Morrisana neighborhood is the hotspot for it. In addition to the tower Chuck located, the surrounding eNBs 53408, 53747, and 41098 have the CBRS panel up.

This convert site is funny to me. T-Mobile reserved a pole at this same intersection for a small cell in Dec 2017, finally installed it in July 2020, only for the small cell to be planned for decommissioning a little less than 1 and a half years later thanks to a convert site.

It looks like the roof was rebuilt/re-enforced for the new setup too. The roof line is a little higher at the front of the building with new bricks.

Thanks! Seems like the Upper East Side is a gold mine for gig+ towers just like the East Village is, as this isn't the first tower they posted, I have 1 previously from them. I may need to plan a trip there soon to add some more, as speedtests seem to be whitelisted again, as I should have hit my deprioritization cap already.

The article has been updated, and Segan found some C-band in Bed-Stuy and Cypress Hills neighborhoods. I don't know the towers in Cypress Hills, but for Bed-Stuy the eNBs are most likely 81272 and 81408. 81408 is the one I know has it, as I walked past it and saw the panel when I was trying to locate T-Mo eNB 128069. First and last time I tower hunt at dusk/night lmao.

For all the hemming and hawing Verizon did about how dire the need for C-band spectrum is they really didn't seem to focus on NYC, like, at all. It's really weird. I guess they are content with the service delivery as it is for the time being. Why rush to 500 Mbps when 100 Mbps is fine.

From the way I see so many C-band panels up around Brooklyn, I would have thought it would be very easy to find and connect to it in any part of NYC. Really surprised everyone is having so much trouble finding C-band live.

On 1/16/2022 at 5:28 PM, Paynefanbro said:

Got around to confirming a bunch of sites on @T-MoblieUser207's keep site map.

Thank you very much! Added and modified all of them.

On 1/16/2022 at 5:28 PM, Paynefanbro said:

Edit: Also wanted to add that n41 in southern Brooklyn is still at 40MHz and Sprint's Band 41 is at 15MHz. I'm not sure what T-Mobile's Band 41 is running at unfortunately.

Sprint should be 15(2599)+10(2645.8) unless things have changed. The 10 MHz is hard to map since they try to keep devices off the 10 MHz. T-Mo B41 is the same 2538.2 found "citywide" (Staten Island is the only one different, 2680 instead), with only one tower in the 40 MHz NR area so far with 2xB41, eNB 131646.

On 1/3/2022 at 10:16 PM, Paynefanbro said:

I'm glad you said this because location 2 and 3 are the locations of two small cells that according to the NYC DoITT were installed in late 2010/early 2011 by Extenet and they actually belonged to Clearwire. They were super rare WiMax small cells that got converted to LTE.

The only reason I wasn't sure if I was actually connected to them was because I noticed that I maintained a strong Band 41 signal while indoors (which is rare for small cells) and also because I wasn't aware that T-Mobile was even broadcasting the keep PLMN on small cells.

Wow, didn't know Clearwire had small cells! I will adjust the data for them. I guess it is time to pay more attention to the small cells now.

On 1/3/2022 at 10:16 PM, Paynefanbro said:

Now I'm wondering what that means for those small cells. Is T-Mobile only temporarily broadcasting the keep PLMN from them because they provide great infill coverage and capacity? Or do they actually plan on replacing those Band 41 small cells with Band 2/46/66/etc. small cells down the line? I don't see T-Mobile keeping them indefinitely since eventually they're gonna need to turn off Band 41 LTE if they plan on expanding n41 beyond 100MHz.

Excellent questions, as I have the same ones too. They can move to 100 MHz n41 without touching the small cells, as it seems like they own 2518-2690 MHz across most of the city, and they dropped the small cells down to 10 MHz everywhere. I fully expect B41 to be the first band shut down for when 140+ n41 happens though, but I would guess its a wait and see to know what happens with these small cells.

Sprint macro conversion at the corner of 15th and 4th (40.63335129349775,-73.98596029635993). Job # B00473152 from the DOB.

I'd guess this is another Sprint macro conversion, they have a site at the corner of 4th and 78th (40.628675236201104,-74.0256740184973). eNB 9387. That's just a guess, though.

Thanks! Updated both of them!

Dual six-port RFS APXVARR18 antennas. I've seen these pop up a few times (example 1, example 2). Not really sure why they go this route for some upgrades.

They have twice the midband capacity of the APXVAR18. So, capacity-wise, this setup should be similar to two APXVAR18s and an APX16.

Ah, thanks! I have been spending quite of bit of time in the area recently, and B2 seems to have recently turned on compared to when I first mapped it, or at least can finally be mapped, I'll try and map B66 for it eventually.

Well I didn't know the edit limit was 30 mins, today I learned.

eNB 78037 | 78038

1. I was unable to confirm the location of this site. I picked up both of these eNBs in separate locations.  I'm guessing that both of these eNBs belong to the same site giving Sprint's eNB numbering scheme. There is an eNB 78039 but it's near West 12th and 6th Avenue according to Cellmapper whereas 78037 and 78038 are in SoHo.

Both of these eNBs lean towards small cells instead of a macro, as both have a Cell 49 found; if it was a macro, only one of the 3 consecutive numbers would have Cell 49, and like you realized, eNB 78039 should have been closer. With Sprint usually leaning to Mobilitie for small cells, I thought locating them at the nearest Mobilitie small cell would be better, but the data up on Cellmapper isn't helpful, so I picked the first location you mentioned for them both until more data for them is available.

Happy New Year to everyone!!

Here is the current number of Sprint sites on the map: 26 planned, 9 confirmed, 10 estimated (need more data), and 4 unknown locations.

T-Mobile eNBs 894592 and 894595, along with 875917, have been confirmed on Cellmapper. 894592 along with its splits center around Sprint eNB 5836, while T-Mobile 875917 centers around Sprint eNB 842901.

I took spin around the city on Cellmapper checking the unconfirmed eNBs for any 8xxxxx eNBs, as they are likely to be converts depending on the bands found. All of them except 2 in Brooklyn I am highly certain of; eNBs 894596 and 875844. Both of these could be small cells, as 891880-891884 are a set of small cells, not conversion sites. They both don't have enough data to be 100% sure, but I added them in case they are.

Found a couple of keep sites.

Sprint eNBs 73932 and 6917 both have T-Mobile gear up, 73932 with the 3 panel setup, 2 slim RFS+6449, with 6917 I'm not sure what the setup is

Both are converted! Sprint eNBs 73932 and 6917 are now T-Mobile eNBs 894580 and 874550 respectively. Did my usual walk around the site while band locking to map the bands for them both. Mapping 874550 was easy, even though the small cell is still live, but something is very strange with 894580, as I was kicked over to other towers/nearby small cells when I band locked 2/66.

894580 pics. I thought it was 2 slim RFS panels, but it's not. I think it is 2 wide RFS panels, but it doesn't make sense to put up 2, so I took multiple photos.

874550 pics. This one is definitely the setup I recognize, 2 slim RFS + 6449.

I see Sprint eNB 5882 has been moved, its coverage spread had me second guessing if I located it right. That means eNB 6854 has been decom'd, with the panels still up as of yesterday. Sprint eNB 5882 also has Verizon and AT&T on that rooftop too?

Finally added all the gig+ towers I found in the East Village, plus one in East Flatbush: eNB 41362. I was unable to take a site pic, but its the same setup that is seen in August 2021 streetview; no LAA or mmWave, just 2/12/41/66/71. I was surprised I passed 800 since I'm de-prioritized, plus a few months ago n41 speeds were awful on this tower.

T-Mobile is moving with conversions. Sprint eNBs 73932 and 6917 both have T-Mobile gear up, 73932 with the 3 panel setup, 2 slim RFS+6449, with 6917 I'm not sure what the setup is, just spotted the slim RFS panel while driving. I'll get pics for them soon, until then they are moved to "conversion in progress" on the map.

Sprint eNB 6898 had its sectors adjusted, so eNBs 253849 and 253848 are closer together compared to the way I located them on Cellmapper/streetview shows them. Here is a pic facing north along Schenectady Avenue taken recently. I expect conversion for this one to happen soon.


In Gowanus/Greenwood Heights, the Sprint keeps eNBs 253785 and 899327 have been updated with their B25/26 eNBs, 5862 and 6832 respectively, both on Cellmapper and on the Google map. Looks like 899327 improves coverage at Lowes, while 253785 does the same for Home Depot. I picked up B41 depending on where I was inside, fully expect B2/66 to reach. I think eNB 6856 is the Sprint eNB for the unknown site at Smith and 5th Streets, but more data is required IMO. I mapped the eNBs under the 312-250 PLMN on Cellmapper for some reason, and I still have no idea what triggers Cellmapper to map under 312-250 instead of 310-120.

Within the Home Depot, the A71 wanted to put me back on T-Mobile signal, even though T-Mobile signal is miserable inside (for now). While the device was trying to find T-Mobile signal, I think it found another convert site. The data that is already up on Cellmapper for the eNB leads me to believe its the former Sprint site on top of the building on the east side of 4th Avenue between 23rd and 24th Streets. Its been added to the google map, as I wouldn't be surprised if it is.

Not sure when this was turned off, but it has been (at least in my neighborhood). All this messing around with n41 could certainly explain all the recent complaints about it in the subreddit.

Earlier this year when the A71 had SA n41 enabled, that is exactly how it was. It was like playing a game with it; some areas had it, then it turned off, and turned on somewhere else, and then turned off again. Must be a lot of testing going on with the way n41 SA and now NR CA shows up and disappears so fast.

I think eNB 5890 has been converted, and if it is, it would be number 5.

#5 is confirmed! I think a valid assumption is there are more converted sites live than we know of. Google maps caught the site mid conversion in July.

eNBs 894592 and 894595 are probably another convert site too, but I don't have any plans to head over to the area to see what is going on anytime soon.

I took a trip to Manhattan during the weekend, and I found a few more gig+ sites, plus confirmed eNB 45463 as one. Kinda hard to tell what sites have/don't have >1G with the A71 since it doesn't take advantage of all the spectrum most macros have, but it's still nice to see 1.1 Gbps with only B66+n41. Most of them were in the East Village, I'll add them to the map over the next few days.
 

Added all 3 sites! I also added 5 sites from my trip yesterday; 2 confirmed (5820, 6898), 3 have unknown locations (6786, 5782, and 6877). 34 sites (24 confirmed, 4 converted, 6 unknown) found so far!

On 12/4/2021 at 2:08 PM, thisischuck01 said:

Yeah, that was my guess. I'm expecting to see a lot of sector azimuth shifts as T-Mobile integrates all these new macro sites into their network.

Same expectations I have, but this one isn't an azimuth change at all, just a location shift on the tower. I was expecting them to move into the middle of Sprint's location if they were changing locations, like they have done on the conversion sites, especially since Sprint's equipment is dormant now.

I should really get a map going of all these keep sites...

Funny enough, I'm currently building it. Still a work in progress, and gig+ towers have also been added on a separate layer since they are still rare to find. I have a list of eNBs, including the ones mentioned in this thread. Currently adding the keep sites, if I missed any gig+ towers let me know.

eNB 5900 is the one that has been fully converted. I'm not sure what happened with the Cellmapper data here, but I think other towers were picked up instead, as nothing has updated the way I expected it to, plus its height means I was probably wasn't connected to it when I thought I was. I couldn't flip through band locking, nor was the time of the day helpful for taking a spin around it.

So I did flip through band locking as the data updated, I forgot I did that. Site has been located, and its the 2 eNB setup; 1 for B41, another for everything else. T-Mobile is moving too fast for me to keep up over here, as I think eNB 5890 has been converted, and if it is, it would be number 5. Might come close to double digits before 2022.

Verizon eNB 81005 has the C-band panel for a few weeks now, finally got a pic of it.

I don't think NR CA is available on the iPhone 13 just yet but I did connect to SA n41 in Brooklyn as recently as Tuesday. I spotted this in my basement with my phone flipping between n41 and n71.

Ah thanks! The iPhone 13 should definitely support NR CA, if it is live. I don't know if Apple has the feature unavailable for use until a carrier(s) want it active though.

I may need to switch from the TMB to XAA CSC sooner than later to bring back the n41 SA option then...

There are a few others which I think T-Mobile may keep, Sprint eNBs 15946, 9727, and either 17822 or 81319 (or both with the moves they have been making), but I haven't verified them yet.

All 5 are being kept, plus eNB 5882, which I didn't expect to be kept. This is going to be an extremely hyper dense macro network. Also to add to the keep list: 5826 and 15941. Album of screenshots past and present here.

I have a sneaky suspicion on where to find #4; it might be Sprint eNB 253934. eNB 5900 is a possibility too, as T-Mobile eNB 894620 has to come from either one of them, and 894620 matches the current Sprint conversion numbering scheme.

253934 has been wiped clean, and eNB 5900 is the one that has been fully converted. Not what I expected at all as eNB 127922 has n41 installed. I wanted a pic from the north (127922 in focus, former 5900 in the background), but did the south instead. You can see a pixelated 127922 if you look very closely, and here are both circled if you can't. I'm not sure what happened with the Cellmapper data here, but I think other towers were picked up instead, as nothing has updated the way I expected it to, plus its height means I was probably wasn't connected to it when I thought I was. I couldn't flip through band locking, nor was the time of the day helpful for taking a spin around it.

The structure at the far left of Sprint's equipment is new. Nov 2020 streetview doesn't have it. If it is Dish, I wonder why they made a new rack instead of using the recently dormant Sprint rack, as this tower is offline. Could also be T-Mobile shifting locations, as I know of a few towers they have with that style of antenna holders.

It's T-Mobile shifting locations.

Kuoppamaki insists that low-to-mid-band carrier aggregation (n41/n71) is already live, but won't tell me where it is. I have been having a lot of trouble finding this mysterious feature in the real world. Other sources tell me that it's live on the network, but no consumer phones have gotten the firmware update needed to enable it on the device side.

PC Mag has a new T-Mobile 5G article here, and I would love to check if n41 SA is live across NYC, as it being live means NR CA is probably also live, but they removed the n41 SA option from my A71. @thisischuck01 have you seen any NR CA since you last saw it, as I have heard the S21 is one of the few, if not the only T-Mobile branded Samsung device that still has the n41 SA option.

I'll have to come back here to remap the site for Cellmapper at some point, so I'll try and get a better picture then.

It's my lucky day, I don't have to remap it, as the eNB has shown up. Shockingly, 2/12/66/71 are all under one eNB, 894640, no split for 12/71; 41 is the only split on the site. Still will revisit to try and get a better side antenna pic.

eNB 55916 is finally fully mapped. Definitely was a midband only site pre-5G upgrades.

The amount of fully converted sites is up to 3 now, as I stumbled into one in Sheepshead Bay; eNB 894600/894602/894603. Google Streetview shows Sprint panels up as of Oct 2019, and the eNB numbering scheme matches the first convert site I mapped. The bus moved too fast for me to realize what I was passing and snag a photo, so I quickly flipped through band locking instead. I have a sneaky suspicion on where to find #4; it might be Sprint eNB 253934. eNB 5900 is a possibility too, as T-Mobile eNB 894620 has to come from either one of them, and 894620 matches the current Sprint conversion numbering scheme.

Very confused how the frequency is 2590-2690, yet the NR EARFCN says differently (2550-2650). Very happy nonetheless, can't wait to hit the gig cap with 100 MHz n41 versus 80 MHz n41, unless the bump to 100 comes with a remote switch to flip on the 10G links too. Still wonder what plans they have for the 40 MHz areas, unless those areas no longer count as parts of NYC and count as suburbs instead /s

I think you mentioned that a conversion you found was in a similar situation - have you stopped by again to see if they decomm'd those when the conversion went live?

Yes, eNB 894588 (conversion site) is on the same intersection as Cells 1/7 of eNB 49470. When I past by the area on November 1st the small cell was still live, same for Nov 20th. I'll pass by it again and see if the situation is still the same.

Dang!! Something I am wondering is if any of these instances with extreme density will result in the nearby T-Mobile site being (eventually) decomm'd. In this situation, at least, I don't really think that that will be the case - unless there's something I don't know, the native site makes more sense to retain.

This one baffled me too. 6853 is much taller than T-Mobile eNB 41532, so I'm guessing they are going for the same setup they have with 42854 and 56208, both of which are walking distance away.

Interesting conversion here - the antenna just right of the 6449 doesn't appear to be the stereotypical APX16. Kinda looks like legacy Sprint gear?

I have no idea, as it was windy so the pic has a slight blur in it. I think its an AIR32, same like with the other conversion site, but I'm not sure. I'll have to come back here to remap the site for Cellmapper at some point, so I'll try and get a better picture then. The one thing I am sure of now though is converted sites broadcast the old Sprint eNB for B25 G block, as both this site and the other one still have Sprint B25 live.

Ugh, this is annoying the hell out of me. Hope they're not just going to lose a weeks worth of data again.

Same here. The Sprint data I mapped showed up with no issue, including the trails that usually take weeks, but T-Mobile's data didn't, yet the data for both carriers were uploaded within seconds of each other. The annoying thing is, the data is there, but its not being pushed to the public, as 2 T-Mobile towers that were on the map months ago, didn't adjust based on the latest data, but updated with the recent mapped data once I moved them.

Apparently there are also keep sites in Lower Manhattan. That's a surprise since both Sprint and T-Mobile had pretty high macro density there pre-merger.

I fully expect sites T-Mo isn't co-located on with Sprint, or on the building immediately next door, they will keep in Manhattan. The macro density will probably be a bit more insane than it currently is.

The structure at the far left of Sprint's equipment is new. Nov 2020 streetview doesn't have it.
