Won't the option(s) to enable be in the *#*#DATA#*#* menu on the Pixel 4?
This is from my Pixel 2

No. The menu is exactly the same on the 4. You can enable and disable individual bands, but not carrier aggregation combinations.

Apparently the Pixel 4 is capable of B25 + 2xCA B41 (3xCA total), no B26 + 1x B41, and 2xCA upload B41. So whenever Sprint enables it, it should work.

(Edited with correct CA combos)

What is "no B26 + 1x B41" ? Specifically the "no".

Which "upload" aggregations is the Pixel 4 capable of? Or were you speaking of uploads only?

It's not enabled on phones. He had to force enable it on his phone. Can't do that on Pixels. So we have to wait for Sprint to push the network config update to devices to tell them they can use it.

What's the ETA on this? What are they gaining by not doing it now?

Sorry, I edited the post and left in the 1x (meaning single carrier) by mistake. It can't do B26+41 at all.

CA combos:

2xCA: 25-25, 25-26, 25-41, 41-41
3xCA: 25-25-25, 25-25-26, 25-41-41, 41x3
And 4x and 5x CA B41.

2xCA upload on B41.

Like the Pixel 3, it's also limited to 10 MIMO streams. So you can do 4x4 on 2 B41 carriers, but only 2x2 on the last one. Likewise, with 5xCA B41, it can only do 2x2 per carrier. No 4x4 at all.

No idea when Sprint will push the update to enable FDD-TDD. Sprint Speed . Could be next week, could be 6-12+ months. Magic Boxes and Airaves for example have been capable of VoLTE for 11+ months, just waiting for Sprint to whitelist them. Things can be ready and working but just sit for a year for seemingly no reason...

So for upload, only 2xCA on B41 is possible on the Pixel 4? How about other devices? My biggest "want" is the best upload speed generally.

Unfortunately, based on LTE standards,  I believe that 2xCA upload is the maximum CA supported for upload for ANY band, so it's a technology limitation at this point. I don't think that will change until 5G becomes more widespread.

That leads to my next question. Can any phone(s), including the Pixel 4, do 25+41 or 25+25 or 26+41 or 26+26 on the upload?

Or are all restricted to 41+41 on the upload?

Yes, Samsung S9 and likely its successors, but Sprint has to allow it first and enable sites etc.

So the S9 and newer Samsung devices are capable of multiple upload CA variations but even newer Pixel devices are not?

No absolutely not. 

Devices support B41+41 on UL CA. Sometimes we see B7+B7 (for canucks). 

Rarely do we see FDD UL CA certified which is definitely not in use and is usually something obscure like B5+B5.

From the Telit LM960 AT! command guide page 253/256 with the AT&T firmware equipped;

2ULCA: 2A-12A, 2A-5A, 4A-12A, 5B

Pretty sure those are all FDD bands sir. This is the SDx20 which is pretty common now in many handsets and routers. There is a minimum one of these in every police cruiser in my county on Firstnet.

This is just on the first batch model. I expect the further United States certified model A18 to incorporate band 14/71 in the upload CA combos as well now that firmware is available for all carriers. The Five Gee capable FN980 will also allow band 14 HPUE with the newest amplifier.

Any FCC links to smartphone device(s) (not tablet / PCIe chips) with said combinations certified?

Great question. I will look! I can grab the 960 off the roof and go get some screens on a modernized site with ATT aggregation on upload. 

I also have a cat20 m.2 chip to test as well with AT&T. A bit smaller form factor. Either way it will be coming to phones and is already active on networks. I get 2+5 upload on the cat 20 with T-Mobile now.

Do you know where I can find a list of bands that THEORETICALLY can support upload carrier aggregation? I don't know why it seems SO DIFFICULT to find that list - Thank you!

LoL he just gonna say no or band 41. Instead of sending you to some clunky FCC web interface here is a list of some FCC certified FDD and TDD combos for domestic;

It was down in the generic firmware bin.

So 2x B41 is the only Sprint upload CA variation possible?

Same exact things are happening to me here in the Boston area. It's becoming very annoying. I resisted from toggling airplane mode the other day and remained roaming for over 6 hours in an area I know Sprint has had good LTE coverage for years. It also seems to struggle to pick LTE back up on its own once it drops back to 3G.. even when in areas of extremely strong LTE signal. Airplane toggle usually grabs LTE immediately, but we shouldn't need to do that.

Hopefully it's a software issue that can be resolved quickly. I have been trying to remember to report it through the My Sprint app, but not sure how helpful that really is.

I usually encounter this after my Caltrain goes through tunnels.  This morning i was pleasantly surprised to see my phone still connected to LTE.  This seems to have come out after/independently of the Dec update.  Has anyone else noticed improved there?

All CA combo's are certified through 3GPP and is available through their release documents. 

Here is one I can find immediately: https://www.3gpp.org/DynaReport/SpecVsWi--36101.htm

It's spread throughout a ton of their release documents and can be hard to pin down at times. 

A useful site I reference a lot is this: http://niviuk.free.fr/lte_ca_band.php 

It aggregates all the CA combinations (UL / DL) and has it in an easily available format for us to peruse.

Negative. 

That is FDD-TDD DL CA utilizing a 10 MHz B25 carrier as PCC for DL /UL with 20 MHz B41 aggregated on the downlink.

I won't pretend and say I know what that is. Is the Pixel 2, 3, or 4 capable of this?

If not, which devices are?

      Just installed the 8.1 update on my Pixel.  Still no Sprint Wi-Fi / LTE calling

      The rumor mill has fully geared up, so it seems time for a thread in which the potential HTC-made 2016 Nexus phones can be discussed.
       
      Rumors suggest two phones: a 5" device codenamed Sailfish, and a larger device codenamed Marlin. Both are thought to be produced by HTC. [There's also a report that Google is making its own phone, without an OEM partner--along the lines of a Pixel phone--but that report has been largely discounted.]
       
      Android Police has claimed it knows with 8/10 certainty some specs of the smaller device--Sailfish:
      Manufactured by HTC 5" 1080p display (~440PPI) Quad-core 2.0GHz 64-bit processor (model unknown) 4GB RAM 2770mAh battery 32GB storage (unknown if multiple models will be available, or even if this is the base storage level) 12MP rear camera, 8MP front Rear-mounted fingerprint scanner USB-C port (bottom) Bottom-firing speaker or speakers (unknown if dual) Top-mounted headphone jack Bluetooth 4.2 Any thoughts on these devices? The last several Nexus devices have been Sprint compatible; is there any reason to think these won't be? Any hints in regulatory filings? How is HTC's radio performance, generally? Will Sprint sell them directly, and even if they do, will it still be preferable to buy directly from Google?

      Only specs I've really seen leaked are 5.7" screen and based on the unannounced "Mate 8" model.
       
      From http://www.breathecast.com/articles/nexus-2015-rumors-news-leaked-video-reveals-specs-of-purported-2015-huawei-nexus-video-30407/
       
       
       
       
       
       
       

      The Mate 7 had a 4100+mah battery, speculation is that this could have the same or bigger.
       
      Anything passed through the FCC for a US and/or Sprint version that covers the Spark bands?  I'm in the market for a new phone this fall and will be going off contract, buying a Nexus.

      Hopefully we can finally start seeing some user feedback. So far so good! it is without a doubt the best device ive owned!!!
    • By topdownat4
      Had not seen a thread for this yet, 
      I see some definite consumer advantages with Sprint's Network combined with TMob and Wi-fi.
      I have had many Nexus devices and I love my Nexus 6, although it is a bit big.
      The price is good for the service. ($20 / unl talk/txt, $10/gb)
       
      I hope the technical aspects work as they propose. I am a Google Voice Number user and love the "Any device" call capability and use it on my Tablet, Chromebook and phone. I rarely actually answer my Phone at the house. Answer the tablet or Chromebook.....
       
      I love Sprint's network, the upgrades they are putting forth and this Site, but if Project Fi works as advertised, it might lure me to sign on.....
       
      What are everyone's thoughts?

    • A great article by Jim Patterson on rcrwireless.com. Some nuggets format 2.5GHz: “Braxton, Mike and John have authorized me to do some work at risk this year in getting ourselves ready to deploy the 2.5 gigahertz spectrum as soon as the deal closes. Nobody is more impatient for this thing to close than me. I wish I was deploying 2.5 radio on the network right now, but we’ve done work at low cost in terms of securing, permitting, and authorization to deploy 2.5. So as soon as this deal closes, we’re in a position where we can start laying down 2.5 radio on the new T-Mobile network.” Enterprise:   T-Mobile inherits not only a trough of spectrum with the Sprint acquisition, but hundreds of seasoned enterprise sales executives.  As Mike Sievert recently acknowledged in his appearance at the Citi conference a month ago, T-Mobile is under-indexed in enterprise.   Sprint’s enterprise roots are significant, having commanded close to 20% of the enterprise data market as recently as 2006.  There are many sales executives who cut their teeth with fleet management solutions (Nextel and Sprint), wireless access solutions (Clearwire and Sprint) and IP MPLS (Sprint).  *Without going through all of the details it’s important to note that the Apple iPhone 7 and iPhone 8 (and their variants) have the 2.5 GHz band already installed in the GSM (T-Mobile) version, and that the CDMA (Sprint) version of these devices already has T-Mobile’s Low Band 700 MHz spectrum, a.k.a. Band 12 (and Band 66 in the case of iPhone 😎 already enabled.  The CDMA version of the iPhone SE also has Band 12 enabled. Bottom line: there is the potential for backwards compatibility within the current handsets. And the iPhone XS (and variants) and iPhone 11 (and variants) are universal devices and include T-Mobile’s 600 MHz band which will be have a big benefit for Sprint customers. https://www.rcrwireless.com/20200216/analyst-angle/the-sunday-brief-new-t-mobile-cat-5-hurricane  
    • Good.  I bought shares in Shentel (SHEN) and US Cellular (USM) a year or two ago when their stock prices went down.  Waiting for a business consolidation event that causes their value to double or more.
    • Nice.  All three of my 4G Sprint phones are ready or near ready for upgrade.  I will wait until the "attractive offers" start.
