modulation and Carrier aggregationa (CA) - Xiaomi Mi 5s Questions & Answers

Is modem mi5s have modulation QAM256 and is can aggregate more than two bands?
By https://www.gsmarena.com/xiaomi_mi_5s-7260.php modem is Cat12 600/150 Mbps and LTE-A (4CA) but I dont think so. I saw only CA two bands B3+B1 (1800MHz 2100MHz). I have never seen CA 3 bands B3+B1+B7 (1800MHz 2100MHz 2600Mhz)

[Q] What LTE Bands are used for Austin, TX?

Was thinking about getting a Note 4 for AT&T. I know that the bands used by a carrier depend on the license for that area. For Austin, Texas does anyone know what AT&T bands and freq uses for LTE? I looked on http://reboot.fcc.gov/spectrumdashboard/resultLicenses.seam which shows the leases for Austin, Texas Travis county but I am not sure what Licensee/Lessee Name to go buy since it's a little confusing.
In Austin TX at least from there 700MHz is definitely deployed for LTE. 1700MHz is deployed but it isn't known not directly in Austin or somewhere else in your county. For 1900PCS it is unclear as they use this for LTE or UMTS along with 850MHz (1900 and 850 is also used by AT&T for edge/GSM too).
700 and 1700 = LTE absolutely for AT&T. For PCS and 850 MHz however this isn't known since they use these bands for different technologies. They also have a deployed WiFi licensed in Austin TX too.
I'd suggest sending an email to AT&T and asking as these are licenses but don't absolutely mean they are deployed.

Does carrier aggregation for AT&T have to be enabled?

This unlocked T-Mobile S6E+ is picking up very strong signals for AT&T LTE on bands B2, B4, and B17, but it's not aggregating them. Should it not be aggregating them?
Does carrier aggregation on B17 have to be enabled on the T-Mobile SGE+?

Differences between US and Euro Version

Hi
Can someone tell me if there is any difference between the US and the Euro version of the Pixel ?
Do they use the same LTE Bands ?
Thx
Lionel
Would like to know as well
There's a $200 difference somewhere!
Just bands and likely the absence in the US model of the certification label at the bottom of the back of the device (like Nexus 6P, that hasn't them in the US version and has them in the international version).
The bands are different. The USA model wouldn't be able to use 4G in Europe. You'd be stuck using 3G.

are you sure ? In my country (Switzerland) we use mostly LTE Bands 3,7 and 20 and as you can see, the 3 bands are in both version.
I only see a difference in the LTE 2X CA and LTE 3X CA where the combinaison are not the same.
Can someone confirm ?

My advice is to wait and see. Google posted a similar spec sheet last year for the Nexus 6P. It was corrected after while. It would be wise to wait until the phone is actually out and see if the page gets corrected.
Should the page be correct, then the USA version will work in Europe. You just won't have lte-advanced. Carrier aggregation depends on band combinations. None of the European bands are combined on the USA version.
Why nobody knows the real name of the models? For the Nexus 5 there was the D820 and D821, what about Pixel?
Here are the answers you guys been waiting for:

FCC changed the rules to allow for device certification notices to be part of the Firmware, Google took advantage of this with the NA model (Settings > About Phone > Regulatory Labels), I'm guessing that there are territories outside USA & Canada that still require the labels on the body of the device.
Yeah that's pretty much what I said lol
US-Model works in Switzerland
according to this site the us-model will work with all bands of all carriers within switzerland: frequencycheck.com/compatibility/kR11C21/google-pixel-xl-2-phone-td-lte-na-g011c-lg-taimen/switzerland
If you are a Project Fi user, another important difference is that you can not use Project Fi with the international version of the Pixel XL.

From that list, it seems that while the international version supports almost all of the bands that the US version does and then some, the US version is still better in the US due to more applicable carrier aggregation support.

US / European Pixel 2 XL network compatibility differences?

Are there any differences between US and European Pixel 2 XL regarding network compatibility? I don't see any difference when comparing tech specs on US/UK/German Google store...
A friend of mine is traveling to Europe so I was thinking I could save $200...
Any ideas?

I received mine one day before traveling from the US to France. Both my home SIM card and the Orange one I use work fine. Service can be spotty but I think that's regional and not a phone issue. I have LTE throughout Paris...
Here's an answer from an expert - top contributor in a topic in the Google Groups "Pixel User Community" group:
Hello there, the original Pixel had some differences in the supported LTE bands and there used to be some differences in supported bands for Pixel 2 at launch as well, but now they seem to have updated the Pixel 2 listings to match on both North American and International variants. So according to those listings, there aren't any differences between the North American and International variants.
On the Google Store site for the Pixel 2 it list the same bands for the US version as the GB version:
https://store.google.com/gb/product/pixel_2_specs?hl=en-GB
https://store.google.com/us/product/pixel_2_specs?hl=en-US
and if you account for the 20% GB VA Tax that is included within the price of the phone the cost of the two are the same (+/- exchange rate)

Verizon Specific Radio?

As the title states, is there a VZW specific radio for the Pixel 2 XL? I have the unlocked international version of the phone.
I've loaded a custom ROM, but the signal strength is poor and data is constantly dropping or switching from 4G > 3G.

Probably has the correct LTE bands for Verizon.

I did find this:
https://forum.xda-developers.com/pixel-2-xl/how-to/testing-performed-factual-information-t3702662
I've also tried all combo's of network type, but nothing seems to help. My 6P runs on VZW just fine using the "Global" for preferred network type.
There's also a post on one of the ROM threads where VZW peeps are having the same issues. I had to revert back to my 6P as the Pixel was unusable with the signal and data drops.
