Has anyone ever seen 3 way carrier aggregation while using T-Mobile with Pixel XL or Pixel? I called T-Mobile support and they do not have an answer to whether or not it will utilize 3x aggregation. I personally have not seen it myself and I'm in an area where it is enabled. Network signal guru only shows 2x aggregation on my phone. Thanks to those who may know if 3x may be utilized with T-Mobile or possibly in the future

I think that it supports 256 QAM but not 4x4 MIMO. I think I read that the SD 821 is capable of 4x4 but I think it's missing other hardware like an amplifier or something. Im no expert but I try to read up on the tech and understand it. The other thing is that the pixel needs to be updated to activate 256 qam

If I'm not mistaken only the T-Mobile variant of the LG V20 supports this at the moment.

Can you explain how you're getting "Network Signal Guru" to show you current CA status? I've downloaded the app and I see no information on current aggregation status.
To my knowledge, There is no way of seeing active CA status on the Pixel XL. Or any phone for that matter outside of the known samsung field test app.
Using a Pixel XL on T-Mobile I've achieved a max download of about 114Mb/s. Which I suspect is only 2x aggregation.
I've achieved 147Mb/s on VZW with 2x Aggregation (I'm guessing 2x due to my Nexus 6p getting the same speeds. Which only supports 2x CA).

Rooted?
If you give it root access, It's a completely different app. Awesome stuff with root.

Pixel XL without Root
http://cdn.141networks.com/images/NSG-PXL.png
So since you guys turned me on to the Network Signal Guru app I did some testing.
I'm convinced the NSG app can't display Carrier Aggregation if it's on the same band. IE 2x CA 4+4 or 3x CA 4+4+12.
With my TMO sim in my Pixel XL, I got speedtests in excess of 100Mb/s. When those tests were ran, The most the app ever reported was 2x CA, Band 4 + Band 12.
The reason I'm convinced it doesn't display CA when it's on two band 4 channels is I ran speed tests >80Mb/s when it claimed I had one 20Mhz Band 4 channel. Which is a FAR reach for a single 20Mhz channel. With this being said. If you're ripping 100+ Mb/s speedtests, And it's showing 2x CA B4+B12, I'd suspect it's acutally 3x CA of B4+B4+B12. And the app just isn't reporting it correctly. Perhaps someone can post an NSG screenshot of it showing 2x B4 channels to prove me wrong.
Here's a screenshot of 1 B4/20Mhz carrier doing 73Mb/s
http://cdn.141networks.com/images/PXL-TMO.png
I'll further comment to say that while the Pixel XL claims it'll support 256QAM, I never saw anything past 64QAM. So it's either not supported. Or not live in my area (Central Florida). We're all aware 4x4 MIMO is also not supported by the PXL.
While I was out and about. I also ran some testing with my primary SIM (Verizon Wireless).

http://cdn.141networks.com/images/PXL-3CA.png
And finally, The local tower that always gives me dumb speed test results. I always assumed it was 3x CA. It reports 2x (B4+B13). Meaning this serving cell is either super unloaded, Or once again, I'm not seeing a 2nd descrete B4 carrier. And it's actually doing 3x CA.

256 QAM went live nationwide in October. According to Tmo the only devices that can utilize it is the gs 7 and gs7 edge. We know the pixel can do it the problem is we need for it to be able to access it on T-Mobiles network. I'm also central Florida

Interesting! I bet they're doing something IMEI based identification of the S7 / S7E that allows it to run a different IMS barer that will run at up to 256QAM. I also suspect this is downlink path only. As in my testing, I never topped 16QAM on uplink (Both TMO and VZW).
I wonder if they have a different APN. Anyone have an S7/S7E that can confirm they have the normal fast.tmo APN?

According to the article I read support for those devices were coming via software update. And it's only download. Upload was 64 QAM. I'll see if I can find the article.

This is because your average rep has no idea what you're talking about. And their script doesn't have any resources to help them answer. You could call three times and get three different answers. Being that TMO pushed a software update to enable it on the S7/S7E, I would argue they would have to do the same to the pixel/pixel xl. Which probably means they would need a TMO specific build. And I just don't see that happening personally.

I have a location in town that does B2+B4+B4 on a V20. My Pixel will not do 3xCA at that location, just 2xCA of B2+B4 or B4+B4. I will verify the V20 with NSG again when I get my hands on one. I only used the built-in engineering mode on the V20 at the time.

I had a feeling that 3x CA didn't work. Another feature of the phone that's not activated. I'm sure something needs to be updated by Google to access this on Tmos network. I'm having Volte issues on TMO with mine. T-Mobile support just tells me to disable it.

The 2x2 MIMO listed there is in reference to the Wi-Fi capabilities of the phone. The Snapdragon 821 uses the Snapdragon X12 modem which, according to Qualcomm's site supports 3x20 MHz carrier aggregation, 256-QAM, and 4x4 MIMO on one carrier.

It doesn't; While the phones x12 modem DOES support 4x4 MIMO and 256QAM, It lacks the hardware (Something about an amplifier and antenna array for 4x4 MIMO). 256QAM is only supported on one of the foreign carriers to my knowledge right now. But They claim it will be enabled on the phone for use with TMO in some future update.

Don't know what happened to my first reply here. So sorry if this is a double post.
I did find that NSG shows 2xCA of the same channel (Found out with a Sprint SIM, B41+B41). And as in my post above. Apparently the Pixel has 3xCA issues with TMO and TMO only.

I'll admit I'm not well versed in MIMO tech (and have seen the other reply about the Wifi spec), but I have seen others report their device does 3xCA on other carriers: Cricket , VZW/ATT

It would appear that the Pixel is having 3XCA issues on TMO. There's a reddit thread about it right now actually https://www.reddit.com/r/tmobile/comments/5qul7p/3x_carrier_aggregation_on_pixel/
TMO Engineer stated that in the lab, With a TMO SIM in the phone. It doesn't report itself as being 3x capable to the serving cell.

where about in cali are you? I assume you are in a 4x4 MIMO and Carrier aggregation enabled region..
Is there anyway to verify if Carrier Aggregation is being enabled?
I usually use root with LTE Explorer to see if it's connecting to two or more bands but it's not showing me on the p3xl (only shows one band at a time)
Just now in Oldsmar Florida. I don't have any of my other phones with me to make a comparison.

I noticed at certain times my kids iPhones display the 5ge icon. I read that aosp added the icon some time ago but I have never once seen it on my 3XL. Anyone else have it?
AT&T has a new conenction they called 5G evo but actually it is 4G not 5G and only certain phones has capability to recevie this signal(iphone X series and qualcomm X24 modem which is Pixel 4 not 3 unfortunately)
Think of it as a Lte advanced but a bit faster(supposed to be but tests shows it is slower according to tomshardware)

Thanks. I knew it wasn't 5g but saw a considerable speed improvement using speedtest.net app on iPhone. I thought I read that aosp added the 5ge icon but I've never seen it. Furthermore, I'm not sure the pixel has the right radio/hardware to pick up the advanced lte . I guess I assumed it did
I just figured it out I think. 5ge operates on Band 14 . Pixel 3xl does not support that band. Pixel 4 does. So in theory the pixel 4 should be able to pull in the 5ge signal but not my 3.
I bought this phone for several reasons, the great Camera, rootability, but Mainly for 5G and faster data. It's Rooted with .037. Since I had my years old sim in the phone all I was able to manage was about 35 Mb/second on 4G. So I headed to the ATT store and got myself a new sim card for it. On the way home I did a speed test and got 75Mb/second, 5G. Great, I thought. So when I got home I wanted to do some speed tests, and it was on 4G. I have an anntlent booster in the house due to having a metal roof. It has the following bands. each can be adjusted Individually:
LTE Band 12 Uplink (698~716MHZ) Downlink (728~746MHZ)
Band 13 Uplink (776~787MHZ) Downlink (746~757MHZ)
CELL Band 5 Uplink (824~849MHZ) Downlink (869~894MHZ)
PCS Band 2 Uplink (1850~1910MHZ) Downlink (1930~1990MHZ)
AWS Band 4 Uplink (1710~1755MHZ) Downlink (2110~2155HZ)
I turned down all the adjustment screws and took the phone outside. It connected to the PCS band 2, 5G. Took it back into the house, it was showing 1-2 bars. So I turned up the gain on band 2. The signal strength jumped up, but the phone instantly jumped to 4G. I thought it was supposed to go to 5G on a strong signal, then fall back to 4g if necessary. I tried *#*#4636#*#* and setting the phone to "nr only", but you night as well piss up a rope, the phone ignores these settings and resets itself to "unknown"
I fiddled with it some more and got a solid 5G icon. But only 5 Mbps download. For a couple hours messing around, and re pointing my antenna to another tower, I finally got a 4G signal on AWS Band 14 with 15Mbps, less than I was getting with my old 4G Sim.
I would like to see this thread developed with better Radio versions, hopefully ones that can be actually locked to what they are set on, whether it be those who want to avoid 5G or those who want to enforce 5G. 5G IS definitely faster in my rural area. Software I used to help diagnose this, and cell tower locations: Network cell info (an older version from an old phone extracted with apk extractor because the new one on google play kept crashing) Open Signal, and I tried Network Signal Guru, but it did nothing on this phone. Please post any ideas you may have concerning Radio connectivity, Booster (resetting) better software and firmware, etc.
@GivIn2It I've changed the prefix of this thread from "Development" to "General" as it didn't qualify for the first. Please review the stuck guidances at the top of the forum and do not change the prefix back.

Does AT&T even have real 5G (NR) deployment in your area? If so, is it NSA? If so, it probably uses B2 as the LTE agg link. According to the site below, ATT is supposed to be on n5/850mhz. You need to find out how ATT handles it's NSA deployment, but I guess you need to have B2 + n5 at a minimum.

Not sure if the Network Signal Guru betas are fully public yet, but they work great with the Pixel 6. No band locking though.

Thanks for that info. Apparantly, there is some aggregation going on. When the phone switches to 5G, none of the software including the Phone Info page will detect what band it's using. Phone info does show NR Available: True and NR State: Not_Restricted.

OK, then. How am I supposed to obtain that device capability information to upload to Cacombos, I don't have software capable of obtaining all that information from the phone. I'm willing to share information if you're willing to share the software that can obtain the information.

But the reason why we need more data is because one report from one phone only reflects the country they're in and what their carrier supports.
It's like cellmapper, more data is better.
I think I have figured out the problem. The Pixel 6 Pro doesn't like it when I have all my gains all the way up, at least for 5G. When I set the bands CELL Band 5 Uplink (824~849MHZ) Downlink (869~894MHZ) and
PCS Band 2 Uplink (1850~1910MHZ) Downlink (1930~1990MHZ) to a little over halfway, the phone regularly connects to 5G, especially when downloading. The signal icon on the phone varies between 2 and 4 bars. Download speeds about 2- 15 Mb/s, which is about a third of my better 4G speeds. But I get to see a pretty 5G icon on my Phone. Superb! My next step is to buy a honkin Yagi to replace my pathetic one, and do some signal searching to see if I can pull in that 75Mb/second tower. If that doesn't work, It's just wait for ATT to improve their 5G here, as I have determined that the Pixel 6 Pro is (mostly) working correctly out of the box, it is looking for the best signal, and if that's 4G, that is what it will switch to. Being more of a hardware guy, I think I can accomplish more with external equipment than I can monkeying with the guts of the phone. Rooting was scary enough. But I'm still open to flashing a better radio, when someone comes up with one.

According to a report by AndroidPolice, U.S. mobile carrier T-mobile plans to bring even faster lightning 5G connection speeds to the Google Pixel 6 handset, with the arrival of next year.
The speed boost will come to both the Pixel 6 and the Pixel 6 Pro, and was actually first discovered by a fan of the publication who decided to check out the modem log of his own daily driver, the Pixel 6. Both members of the Pixel 6 series carry Samsung's in-house Exynos 5123b wireless connection modem, which was freshly released this year.
The modem log, which he has since submitted and is hosted on 4G/5G Bands & Combos, simply revealed the way that the modem handled both uplink and downlink traffic, employing various channels on multiple different bands of the spectrum. This is known as carrier aggregation, or CA, because use of the available resources is simply optimized to allow for a higher data rate per each cell.
The website 4G/5G Bands & Combos serves to list just such data, which is based on real logs from on-board smartphone modems—since a smartphone or modem maker will never actually tell you their supported combinations for 4G or 5G carrier aggregation as part of your device specs; they simply show you a 4G/5G support category number, and leave it at that.
The new log, when contrasted against the previous one from October, contains a new carrier aggregation combination for two of the 5G bands: n71 and n41. According to AndroidPolice's sleuthing, these are actually a direct match to two of T-Mobile's airwaves, 600 MHz and 2.5 GHZ. T-Mobile has apparently been testing carrier aggregation on these airwaves since 2020, and plans to send it live in 2022.
When T-Mobile finally turns on its 5G network carrier aggregation next year, the Pixel 6 and Pixel 6 Pro—which already feature millimeter wave 5G reception—will be all set to boost their wireless connection speeds to even higher limits than before.

It just depends where you are at. Those speeds are at my home. I've seen speeds of over 800 Mbps in certain areas where I live, and speeds of about 200 Mbps in others. I've seen others, in different places (somewhere in the east coast) get over 1 Gbps.

I'm lucky if I break 20Mbps. All of us people living in densely populated areas struggle with the speeds being slower than molasses sliding down a tree in the Arctic lol.
Thought I'd just drop in and say I managed to get this speed today with my 6 Pro whilst stopped at the traffic lights in my CBD area (Telstra 5G network in Adelaide, South Australia).
Must have been a really good sweet spot as never seen those speeds before! (My previous record was 700-800Mbps at my workplace with my Oppo Find X2 Pro).

Wow- the best I have gotten is a little over 800Mbs
That's it.... Time to show you guys what's up. 25 Mbps... Beat that! Lol.
It would've been nice if these sites properly credited me for the modem logs.
*looking at XDA in particular*
I've also since proven that the NR-CA works at a live site on Long Island. One of the quickest turnarounds I've ever done for testing.

Holy ****!!! I've only had my phone less than a week and I live in NYC but the fastest I've got was about 500Mbps, with an average of 200
I just tested my ip13 on tmo 5g UC 600-700dl 60up
They just upgraded the tower across the street where I live
My pixel 6 pro is with Big Red
given verizon is not that great at my house and tmo just upgraded.. may be time for "Keep and switch" promo over to tmobile.

Network Signal Guru - Apps on Google Play
4G 5G signal test, lock band lock rat etc.
play.google.com
Working great on my rooted Pixel 6, FYI this app requires root

I've been testing this for around a month. Works quite well but dual SIM or leaving DSDS enabled can be a little weird.
Band locking is not possible and likely will never be.
Interesting, thanks. The ads aren't being blocked by AdAway (root) and the app would cost $50 a month for advanced features, but I'm sure some interesting data can still come out of it for free.
I used this app for band locking. What else can we use it for if it doesnt support that

Looks like it's capable (and defaults to as long as it's running) of testing your connectivity. I don't know specifics and would likely only use it if I had a problem, which I haven't.
An excerpt of the description in the app store:
Network Signal Guru (NSG) is a multi-functional Android OS based tool for voice and data service quality troubleshooting, RF optimization and engineering field work. It supports all wireless network technologies worldwide, and covers multiple mobile layers as well as data stack in real-time. NSG provides extensive test functions for voice, data tests to assess and reflect the real end-user experience of QoS within a mobile network.
NSG covers all test functions and latest technologies such as: GSM, GPRS, EDGE, UMTS, HSDPA, HSUPA, CDMA2000, EVDO, LTE, NR5G. NSG integrates full recording and decoding of protocol layers on the supported technologies(3GPP, Layer2, Layer3 and SIP) and direct decoding of Layer 3 signaling and data protocol packets on cell phones.
NSG Map offers comprehensive and valuable benefits to combine outdoor and indoor measurements, which reduces the complexity of in locations such as subway, malls or airports.
NSG needs two prequisite conditions before you are using this tool. first only support Qualcomm chipset models. Secondly NSG need cell phone a super user access within your android phone and you have to root the device before NSG is running.

Notice that it still says Qualcomm only in the description, but in the What's New section:
**New**
- Exynos support (Pixel 6)
**Fix**
- Dual 5G (Qualcomm)
- Cumulative decode bugs

It's a monitoring tool first and foremost.
I'm looking forward to positively identifying new cells/PCIs, new band broadcasts like n77 or n41 SA, or emerging technologies like 5G carrier aggregation or VoNR.

Thanks for replying. I am a noob and having all the info the app gives is basically a new language. But I have a feeling even if I did know what the information is telling me I couldn't really do anything with it.
I am in the middle of switching service providers and I have a sim card of all three providers in my country. If someone can help me understand what to look for so I can choose the best provider

It depends on the carrier and how activated the sim card is, but you should be able to use NSG or other, free apps like CellMapper to measure your signals and coverage.
Carrier maps are also an option if you trust them.
And don't worry about understanding all the data. I only understand a fraction of it myself.
The key metrics are easy and for all of them, higher values (or closer to zero if negative) are better.
RSRP = Reference Signal Received Power
RSRQ = Reference Signal Received Quality
SINR = Signal to Interference plus Noise Ratio
Also useful to see how wide your signals are. A 5 MHz wide signal at 600 MHz will be extremely slow but have greater coverage than a super-fast 80 MHz wide signal at 2.5 GHz.
Can someone verify if NSG exposes the QCI on Exynos like it does on Qualcomm? My Pixel 3 XL doesn't seem to work with it and my HTC 10, which does work, isn't whitelisted for AT&T so if I put an AT&T SIM in it, I risk them blocking my SIM (and I would rather not mess with the IMEI to get around that) and the battery on the 10 is going to go totally kaput soon anyway.
On Qualcomm, this an example of what the screen looks like

I'm not very experienced with this app, but I've got it running, gave it root permissions, it's testing. I turned Wi-Fi off just in case that would help progress. Everything below the GUTI line is blank so far, but I'll leave it running for a while and see if anything happens, and report back. I have not paid the $50 per month for the app, for what it's worth.

Pixels are apparently pretty fussy because of Google so it's probable that there's more to do than just install it but I don't know what those things are unfortunately since I don't have it working on my 3 XL either. Thanks for checking though, would be a nice perk.

Thanks for checking. It probably needs a custom kernel or something. I saw a post about, I think it was the 4 XL, needing some special userdebug kernel because Google switched to AOSP variants or something like that. I only briefly skimmed it but it sounded like a hassle. Probably why it doesn't work on my 3 XL but I tried the Kirisakura kernel and it didn't work on that either.
It's not like a critical feature or anything but I help people find prepaid plans and the QCI determines network deprioritization policies and a lot of the QCI info that I've gathered hasn't been updated in years so I was going to start buying a SIM to test every so often and update all of it.
I have working QCI.
It should be noted that the app works a lot better if you disable DSDS in the phone's secret menu. NSG tends to get confused about which SIM card it should show info on if you have DSDS enabled.

What was needed to get the app working? Custom ROM, kernel? Or just disable DSDS?
Hearing that you can see the QCI has pushed me over the edge and I'm going to get a 6 next month, just need to know if there is anything specific to get it working.
Stock rom. Rooted. That's all you need. Might need a license for band locking and advanced functions.

Any idea why @mightyvenom is only seeing the IMS QCI on the Pixel 6?
Does Network Signal Guru display the QCI?
I test prepaid plans and part of that process involves checking the QCI. I know that Exynos modems have limitations that Snapdragon ones don't. My Pixel 3 XL unfortunately is not supported for NSG and if I can test this with a 6, I'll definitely...

Just a note on the band locking menu. What you see is what you get. NSG exposes the entire hidden baseband console as-is. Anything you touch will persist through a reboot and that ENDC stuff is completely undocumented.
Google and Samsung need to update the modem to allow 5G band locking or toggling NSA/SA.
