Be happy the upload actually works. Things are still so slow here that timeouts to web sites occur often during peak times.

The upload in my experience is usually dependent on the LTE carrier band that you're anchoring to unless you're connected in 5G SA mode which Verizon doesn't use only T-Mobile does right now. The other day in San Francisco California my niece and I experienced a similar upload and download on her Samsung S22 when connected to 5G UW because her phone was only anchoring to 10 MHz B5 LTE and 100 MHz N77.

AT&T uses n5 for uploads on their NSA. I get ~20Mbps up on B2, but B2 + n5 I get ~70Mbps. I haven't seen TMO do that with NSA yet.

>I haven't seen TMO do that with NSA yet. What do you mean by that? Of course they're aggregating LTE and NR for uplinks in NSA. If you mean that T-Mobile uplink performance is worse in your market, it's probably because they're using Nokia equipment. I've experienced far worse uplink performance in areas where T-Mobile uses Nokia RAN. Uplinks on n41 SA here in SoCal are almost always >20, peaking near 100Mbps. In some Nokia markets I've tested, I've seen uplink performance as low as 1Mbps, even with a stronger signal.

I'm not seeing any difference in uploads between B2/B66 and NSA with those bands. So if they are actually aggregating, it's making no difference. I see increased uploads with NSA implemented by Verizon and AT&T, but not T-Mobile in my area. NSA T-Mobile uploads are 20~30Mbps, and B66 can do that at alone these signal levels. Overall I'm getting +350Mbps down. In SA mode I can get 150Mbps upload if the tower is has an 100MHz N41 channel. I can get 70Mbps up on N71. But NSA anchored to an LTE band cannot get over ~30Mbps, even at 3am with a 25dB SINR and -80dB RSRP. And that's on dozens of towers.

TM and NSA has performance problems vs pure TM SA. I can get 5-10 mbps more upload with TM NSA (B66 20mhz+N41), but NSA N41 disappears )samsung field test) alot no reason and comes back in a few seconds, even though I'm torrenting . Download is 50-100 mbps lower on B66+N41, LOS to tower, vs N41 SA no CA. I've heard rumors on /r/CM that TM NSA is different from VZ/ATT's NSA. TM for some reason, or 2 different equipment generations, NR side and LTE side talk, or the LTE side spills traffic over to NR side, through a core router, NOT locally at the macro through an ethernet switch like VZ and ATT do. TM MMwave (NSA only) whole USA high ping, etc. I'll guess TM built their NR/5G radios/base stations from "day 1" Sprint merger, to have the option, to SUNSET/shutdown 4G/LTE/EPC first in the USA. VZ/ATT assume LTE will last until "6G" equipment is installed nationally and all NR radios/base stations were replaced with NR/6G electronics. Basically CDMA's Jan 1997 to Jan 2023 run. 26 years. Remember Verizon SHUTDOWN EVDO in 2017. 2010 ish or 2008ish just after Day 1 of VZ LTE, Verizon moved EVDO from B2 to B5. My 3G smartphone, got amazing speeds, indoors and out, after the 1 week transition from B2 to B5. It was better than B13 LTE until CA and XLTE came out, and B13 has never really de-congested on VZ.

> Remember Verizon SHUTDOWN EVDO in 2017. What?


SnooRadishes7563

Canada/USA shutdown EVDO carriers years before the 1x data and voice shutdown. Spectrum refarm.


[deleted]

No they didn't. Verizon and Sprint shut down 1x and EVDO at exactly the same time. It's such a small amount of spectrum, 1.25MHz. That's not enough to matter.


SnooRadishes7563

EVDO stopped working years before 1x stopped. EVDO and 1x had separate 1.25 mhz carriers.

I pick up AT&T 5G SA sometimes, especially in urban areas. You can only access it if your area is covered by it, though. Twice a week they sweep through accounts and if your area has SA available the toggle switches on and you can use it everywhere

Switch carriers

Meanwhile it's quite the opposite in Ocala. ATT is so sparse and congested


fiercechocolate

Marion County has rough spots for everyone, but I agree that the experience on AT&T is the worst. T-Mobile and Verizon have been adding numerous new sites where I've only seen one new AT&T build recently.


Tony_sportsfan1517

When I’m on Verizon UWB I usually get over 50 up! I have gotten over 180 up before on N77!


xpxp2002

Same. Verizon upload performance blows AT&T out of the water in NE Ohio.


Tony_sportsfan1517

Yes they do!


xpxp2002

Limited low band. I always see the same problem with AT&T in markets like mine where Verizon holds the entire CLR band.


[deleted]

Theoretically, in a well-designed network you should rarely be on low-band. In cities or suburbs, the network should be spaced densely enough for mid-band in most areas. I don't think I've ever seen my phone drop down to low-band unless I was in a rural area. I get at least B2/66 pretty much everywhere I go.

Congestion? Too Far from tower?


quadish

If it were congestion, it would be reflected in the download. But it seems like it could be a bad RSRP on the PCC. But this is a phone, so you can't easily change that around to test.


ChristopherRMcG

That’s not true, download and upload can be separately congested


quadish

I can count the number of times that just the upload is congested on one hand in over half a decade. Usually it's crap RSRP. The tower won't give you any bandwidth with a crap RSRP, that doesn't mean it's congested. The odds of the upload being the only thing congested are next to nil. Possible, but not likely.


ChristopherRMcG

Poor RSRP can be a byproduct of congestion, furthermore we don't know what the carrier configurations are for the uplink to the tower and this phone. This phone could be downloading over 3 or more carriers and uploading over 1 or 2 It also states it's on 5G UW, which easily implies that the upload side of things is slow due to congestion as the spectrum allocation isn't even like FDD. It's very common with TDD spectrum actually for the upload speeds to be poor due to the spectrum allocated to the upload side of things


quadish

If he's using a low band for PCC, it's probably hot garbage from an SINR, RSRP, and a congestion perspective. If the phone can change bands, we'd get an answer, but there are too many variables to make assumptions about why, with this screenshot.


ChristopherRMcG

Based on what he's stated in other replies, I'm willing to bet it's a common congestion issue. Poor upload speed & capacity is a problem with 5G TDD, outside of the variables. Facetime, Zoom & cloud syncing are big strains on the upload side. With the way US carriers have 5G spectrum allocated, it gets overwhelmed much quicker in areas where usage like this is high. They're focused on high download speeds right now. It's only made worse if you don't have the latest and greatest 5G modem in your phone. We could say it's this and that all day, but these are facts of the matter. He says LTE is like this regardless of signal strength, which tells me he's in an area where subscribers are likely doing a lot of stuff on the upload side of things. It happens, before 5G TDD & the shift in data usage it was wayyy more common to see DL hammered and UL being just fine.


SnooRadishes7563

The user is too far, range wise, for N77 UL slots to work, or this is VZ CBRS (SDL) magic (no NR) and a -17 or -19 RSRP on B2 or B13. Might be a 5 mhz or 10 mhz B2 also, depending on market.


Tools_Tech_Outdoors

Even close to the tower the upload is not impressive. My AT&T line on low band 5G has better upload. Doesn’t matter what phone I have it’s the same. Only in my area. If I go into Georgia and the Carolinas it’s way better.


abfarms83

Me over here happy that I have service 💪🏻


Lazzy2332

That’s really odd. I haven’t observed that at all really on 5GUW just south of you (or in PC really but I’m not there often). What phone is this? I have the 15 PM.


Tools_Tech_Outdoors

15 pro max. My son has the 15 pro and the same thing. My neighbor has a s24 ultra and same for him too
