LTE Carrier Aggregation / Bands Info? - Xiaomi Redmi Note 6 Pro Questions & Answers

I'm not able to find "official" info beyond LTE Cat 12/​7 about LTE Carrier Aggregation / Bands Support of RN6P.
Especially interested in the Central European situation, as far as I found 3CA (B3+B20+B7+B1) and 2CA (B3+B20/B7, B1+B20) are important to reach high speeds (over 100 Mbps). Other Bands of interest: B32.
Why no Shops and Smartphone tests listen this data which can decide if double or triple speed is possible?
EDIT: According to gadgetsnow.com there is support only for: 1, 3, 5, 40, 41 - so B20 and B7 as well as B32 is missing.
Still found no info on CA (2CA or 3CA); it seems unsupported?

I'm also looking for this CA information but no specs from Xiaomi side.
Note: The answer is 3CA since RN6 has Snapdragon 636 (with X12 modem build in),

Very interesting info and link. So 3CA Downlink and 2CA Uplink. The X12 LTE Modem page also lists a lot more interesting specs like:
LTE Category 13 (uplink) 12 (downlink), Download 600 Mbps Upload 150 Mbps

Unclear to me is if any of this hardware options are usable on devices having the modem installed - or in other words how much device/vendor drivers impact usage of the full hardware potential. Also wondering if Snapdragon 821/820/66x devices so in theory have the same LTE performance?

Xiaomi may not implement every feature as Qualcomm could offer. There is way to confirm CA combinations support from modem log. I have instruction here how to get log out: https://mt-tech.fi/en/how-to-get-4g-supported-ca-combinations-from-your-android-phone/ (scroll down Xiaomi section). Then please send your phone log here https://cacombos.com/contribute so then you can see your device in cacombos.com page with supported bands and combos.

Any chance to enable all LTE frequency supported by MSM8960?

Dear All,
I recently got this device in Hong Kong and is hapi with its performance!
But I am still wondering if this device could actually use the LTE available in HK?
I knw the msm8960 claimed to be capable of utilizing all frequency of radio,
so is it possible that there is some soft lock in the baseband?
Could i flash the baseband or replace the modem driver from other device to access other frequency?
any idea is appreciated!
Thanks!

I think it has to modifiy the ROm and the hardware
I tried to figure out, if our Photon Q is supporting more LTE bands than 1900 MHz (#2 or/and #25).
-> http://en.wikipedia.org/wiki/E-UTRA#Frequency_bands_and_channel_bandwidths
On some sites there are reports for having another band. (Have to search again, I think it was 850 MHz, #26 or 700 MHz, #12/#17/#29.)
I have also searched for supported frequencies for MSM8960.
I found some BlackBerry devices based on that SoC and 2 different versions of supported LTE bands.
One version (UK) supported 4 in europe used bands und the other version (US) supported 4 in US/Canada used bands.
I think that the Photon Q is like the BlackBerry US version and supports 4 LTE bands in US/Canada.
If you need a few sites, I will search again and show it to you.
The strange thing is, if I set to LTE only (via 4636) I can see all 4 carrier (germany).
We have 3 bands with LTE on it, but I can only get signal to max 2 of them.
Band 3, 7 and 20 (1800, 2600, 800 MHz).
The weird thing is, that on band #20 (800 MHz) only 3 carrier are active, so it has to be band #3 or #7.
Maybe I'm missinterpreting things and thats just a sideeffect of crossing bands of LTE US and UMTS Germany.
On stock ROM there was another "secret phone code" to see what the phone-part is doing. (From qualcomm I believe.)
I think I will test it some other day, to see which band is active.
At last, I was never been able to "login" or "register" into my carriers network within LTE.
Please discuss about that possibility, I really want to find out, which frequencies are supported by our phone on LTE.

Dear Loader009,
Thanks for your information! I'm really impressed that you could actually search the carrier in 'LTE only from Germany!
Could you please share the version of ROM you are using?
And if possible, any screenshot? I really want it can be used in HK with LTE(1800, 2100 & 2600Mhz)
Also do you have more information about the secret phone code? I think it would be interesting
Actually, I noted that xt925 and xt905 are using the same chip MSM8960 with LTE usable in HK.
Is there anyone can locate the radio/baseband of their rom and port it for XT897?
I am willing to try it with my machine.
If this work, I think we could use this photon q all over the world!
Any idea?
Regards,
Vasco

Of course, I was just blind guessing the hardware for xt926 and xt907 are using the same hardware.
If not, there should be one chip controlling the modem channel of the device to be replaced.
But WHICH ONE???
Any expert in this area can solve this question? I am a dummy for radio stuffs
This seems like it's getting pretty interesting.

Dear all,
I'm also very interested in this topic since I imported a Photon Q to Germany and was wondering if it's possible to use the local LTE 800/1800/2600 bands.
I think the first thing we have to find out is whether the hardware is capable of using other bands than the 1900 band listed on the Motorola website. As Loader009 states he could see LTE carriers which are known to use different bands I assume the hardware can do it. Otherwise the carriers wouldn't have been listed, right? Maybe someone from another country with different frequency bands can check and confirm that he can see those carriers as well?
Thus, the limitation to the 1900 band should be software-made and could be modified by a developer. I hope someone can participate at that point as I don't know much about coding...
I'm using CM10.1.
I can't remember the secret phone code, I have to do research again.
This secret phone code only works on Stock ROM. (I stupidly deleted it, when it wasn't working on CM10 anymore.)
The one secret phone code I used to force "LTE only" was *#*#4636#*#*.
Please DON'T change the baseband (don't even tap on it).
This can do problems to you. (I had to use QPST to recover the supported frequencies.)
Also, developers (afaik) can't modify the modem firmware.
We also don't even know, which LTE bands the Photon Q is capable of. (Except 1900 MHz)
I've got my 32GB SDCard back and will test it in the next few days out.
I hope I'll find that secret phone code, I'll also make a few screenshots.
Got the code!
##33284# <- ##DEBUG#
It only works on stock afair!
I'll test tomorrow, it's about 3am now >.<

I have read the "QU_SnapdragonS4_White_Paper_FNL_Rev6.pdf" and found there following entry:
-----------------------------------------------------------
• Industry’s first fully integrated 3G/4G world/multimode LTE Modem: <<<Supports all of the world’s leading 2G, 3G and 4G LTE standards>>>.
It also includes integrated support for multiple satellite position networks (GPS and GLONASS) as well as short range radios via Bluetooth,
WiFi, FM and NFC.
• Designed for speed, compatibility and power savings:
Snapdragon S4 Processor MSM8960 chipset includes the industry’s only complete platform that integrates all of the world’s leading 2G, 3G and 4G mobile broadband modem technologies on a single chip. This new integrated multimode modem is based on an advanced, programmable architecture that is performance, size and power optimized for the fastest combination of modems available for:
- LTE FDD/TDD (Cat3)
- 3G (DC-HSPA+ Cat 24)
- EV-DO Rev. B
- 1x Advanced
- TD-SCDMA
- GSM/GPRS/EDGE NFC.
Multimode/Multiband Means Worldwide Coverage.
• Support for multiple radio frequencies: Mobile broadband technologies are growing increasingly complex in their implementation. LTE is currently being implemented in over 40 diff erent radio frequency bands throughout the world. To complement its wide range of modem standards supported, Qualcomm has designed the Snapdragon S4 Processor MSM8960 CHIPSET platform to <<< address all commonly-used frequencies (from 700–2600 MHz) and bandwidths up to 20 MHz>>>, allowing its customers to address any mobile network opportunity whether the simplest single frequency implementation to the most extensive multi-frequency global mode, whether 4G, 3G or 2G.
-----------------------------------------------------------
Based on the document the chip can handle all LTE Standards, but it depends on his "advanced, programmable architecture"....as written there and how Motorola / Sprint implemented this, maybe they reduced LTE only to one Standard.
I don't have LTE in my area and so I cannot test this.
That's possibly right.
Something else:
If I remember correctly, somewhere in this forum have been said that for CDMA the internal Sprint "ID"(?) is used.
Maybe that's also the reason why I cannot connect to LTE in my area.
The phone is trying to "login" with the Sprint ID and this of course won't work.
The ##DEBUG# menu wasn't helpfull. It shows frequencies for american standards and not for GSM/WCDMA.
Also the LTE menu is also not very helpfull, it doesn't show frequencies at all.
Any News on this topic?
Maybe one of the developers can give a statement?
Yesterday I tested a LTE compatible SIM card.
My Bro has a Samsung Galaxy S4 with 4G/LTE in my area.
So I've put his SIM-Card into my Photon Q and set LTE only.
I had no luck, the Phone couldn't register into the network for this SIM.
I guess either it has the wrong frequencies or LTE is for inbuilt "SIM" (Sprint SIM?) only.
The latter. LTE is configured only for 1900 MHz which Sprint uses.
LTE is configured only for Sprint's frequencies, however, it supports the United States frequencies of PCS blocks A-G. The G Block is Sprint's current LTE channel, and they may deploy it later on Blocks A through F, depending on if they own the spectrum in a given market. The reason you see EU networks when the phone is in LTE Only Mode is most likely because the Phone still sees GSM signals, but will only connect to LTE ones from those GSM signals. Likewise, in the US, if you force LTE Only and then search for networks, AT&T and T-Mobile US will come up as the GSM carriers the Photon Q sees, rather than the LTE signals it sees.
Setting the Photon to LTE Only will not do anything for LTE in the EU. I suspect that if another carrier in the EU uses the 1900 MHz for LTE, the Photon Q will have no issues connecting to LTE in Europe. But until that time, be happy with HSPA.

Can this configuration theoretically be changed / other frequencies be added?
Only if you break BP security.

Sorry, what's that?
IIRC The only place with 850mhz LTE available is the Chicago market and currently no phones at all support it. :crying:

V20 will have lte band 66 for aws

https://www.google.com/amp/www.tmonews.com/2016/09/t-mobile-lg-v20-lte-band-66-support/amp/
What's the benefit of band 66? I can't find the info anywhere . do you know if.it's wideband 20x20 or like.band 12 5x5? I can't find any info that makes sense to me at least

Canadian service provider Wind Mobile has plans for it:

Found this as well,may have some future benefit/etc..... for US Carriers:
http://www.fiercewireless.com/wirel...or-band-66-combines-its-aws-4-aws-1-and-aws-3
I tried the *#546368#*918#, Field Test, Modem Settings, LTE Band Selection
I see options for Bands:
1,2,3,4,5,7,8,12,13,17,20,25,28,29,30,40
Some of the bands fail to enable.
Is there some other option to enable/disable to get to Band 66 or is it a collection of bands enabled or ???
Not much more info here either, http://forum.xda-developers.com/v20/how-to/band-66-disabled-t3491556
Though, this page for LG, www.lg.com/us/cell-phones/lg-H918-Titan-v20, does show it as (is there a H918 and H918 Titan because in my model, it says H918):
GSM 850/900/1800/1900 MHz, LTE Bands 2/4/12/66, Roaming 1/3/5/7/13/20, WCDMA Bands B2/B4, WCDMA Roaming B1/B5
This post says the H915 variant (which I returned since it has a locked bootloader; so much for FREEDOM Mobile) does not show Band 66 either, http://forum.xda-developers.com/v20/how-to/freedom-mobile-lte-lte-network-t3517501
From Freedom's page regarding their LTE rollout:
Frequency:
• AWS-3 / Band 66 in the Greater Toronto and Vancouver areas, Calgary and Edmonton
• AWS-1 / Band 4 in Eastern Ontario, including Ottawa, Kingston and Peterborough

it's coming as a future firmware upgrade.
Supposed to roll out by January.
It works similar to the Samsung 3 band thing, in which it taps into 3 LTE spots to provide a faster speed, also makes it compatible for people in AWS bands (Wind Mobile / T-mobile)
Oh, good to know then. So, for "Freedom" mobile, only eastern Canada users with Band 7 (2600) phones (and possibly certain plans can get LTE); western Canada users will have to wait for the Band 66 to be activated :/ *sigh*.

I can tell for sure latest update for H915 activated band 66, despite it not showing up in the LTE bands in the modem settings field test menu. If I force the phone to LTE-only mode I can see it trying to connect to B66 LTE in the engineering menu, just cannot connect because I didn't change my plan.

FRD-L04 - Which LTE Bands?

Hi all,
Looking at replacing my Nexus 5X with an Honor 8 from the US (FRD-L04). I split my time between the USA and Australia, and as such I need good band support in both countries.
In the USA, I use T-Mobile which looks as though it'll be fine.
In Australia, I use Telstra. They use the following frequencies:
LTE
Name Interface
B1 (2100) LTE
B3 (1800 +) LTE
B28 (700 APT) LTE
Supported LTE Protocols
Name Generation
LTE 4G
LTE-A 4G
Click to expand...
Click to collapse
As well as:
UMTS
Name Interface
B1 (2100) UMTS
B5 (850) UMTS
Click to expand...
Click to collapse
I am a bit confused, because in some places it indicates that the phone does not support the LTE bands in Australia. But according to the HiHonor website, it supports all but one of them.
Any guidance on this? Thanks.

Hmm, see here is the problem.
According to frequencycheck, L14 supports B1 and 3, but not 28 and L04 supports neither.
But yet according to Honor themselves and even BestBuy, the phone should support everything I need for both Telstra and T-Mobile (except Band 28 which is no big deal for me).
So, which is correct? I'm sure you can see my confusion.

Trust the manufacturer. Honor official site will have correct info
I can confirm FrequencyCheck is incorrect. I can also, however, say I wouldn't want a phone without band 28 in your situation. The lower frequency should have much better coverage.

4g+ problem

my oprator 4g+ work on band b3 & b7 but my phone just show 4g on statu bar but other phone like samsung show 4g+ on same area.my rom is 8.2.2 global stable.
is mi 5s plus suppport 4g+?
Maybe don't support
But I cannot call or receive calls only one SIM card work for call I use two operator
Irancell SIM card on slot 1 have internet and call other slot don't work internet and call then change sim card in slots HAMRAHawal can call in other slot irancell only have 4g internet and cannot call
When say problems with this phone in Miui forum manager banned me and don't help
I very very angry when saying problems and manager miui banned me why ?!!!!!!!!!!!!!!!!!!!!!!!
The xiaomi is cheating and cheaters the people of word and don't help the rubber is better than xiaomi
Pretty sure only SIM slot 1 supports 4G, slot 2 is 3G. I didn't buy it for the dual SIM stuff so I have only tested the first SIM slot and have had no problems with 4G.
As for 4G+, that is just a branding thing. 4G+ is 4G. there is no difference. The only reason that some phones put 4G+ on their status bar is just that they modified the icons in the ROM.
see - https://en.wikipedia.org/wiki/4G
If the phone says 4G, you are gettign 4G. The important quote on that page is:
Confusion has been caused by some mobile carriers who have launched products advertised as 4G but which according to some sources are pre-4G versions, commonly referred to as '3.9G', which do not follow the ITU-R defined principles for 4G standards, but today can be called 4G according to ITU-R. Vodafone NL for example, advertised LTE as '4G', while advertising now LTE Advanced as their '4G+' service which actually is (True) 4G. A common argument for branding 3.9G systems as new-generation is that they use different frequency bands from 3G technologies ; that they are based on a new radio-interface paradigm ; and that the standards are not backwards compatible with 3G, whilst some of the standards are forwards compatible with IMT-2000 compliant versions of the same standards.
4G+ is just true 4G. So if the Mi 5S Plus says 4G, you are getting 4G (or 4G+ as they are identical).
You can verify this with any LTE bandwidth monitor apps (such as signal spy) which will tell you that you are on LTE and which band you are on and you will know then that you are on 4G.
Hi mates. I'm living in Netherlands ...have problem with 4g..
My phone doesn't support band 20 ( 800 mhz )..
Is there an option to access 4g?...
Maybe flashing a custom ROM ?...
thanks
bmg002 thanks for your help.the app like signal spy does not work on my phone because of my phone is not rooted.do you know any app that i see network aggration without root?
offhand, I do not know of any non-root tools for getting any information about what network you are on.
My next best bet would be to get some bandwidth testing tool (speedtest for example) and then check what speeds you are getting out of 4G and compare that with what your provider claims you should be getting. My provider gives me 750 Mbit/s as a peak speed, and 250 Mbit/s average. If your speeds are close to that, then that is all that really matters. If it indicates 4G or 4G+ or 4G LTE or whatever indicator it says in the top, if your speeds are slower than what you are paying for, you will want to look at rooting and opening up some of the 4G channels which will likely give you better speeds.
If you still have your old phone, do a speed comparison in speedtest (or equivalent) and see if it is faster or slower on the new phone. If it is marginally slower (or faster) that can likely be ignored. If they are drastically different, then I'd look at rooting and unlocking other channels.

If you need to access 4G and your operator only supports band 20, then your only option is to use a different phone. From everything I've read on this forum, the hardware has been modified to not support band 20 due to licensing concerns. So a custom ROM or custom Kernel will not affect being able to use band 20. There is no way around it at this time that I am aware of.
Now, if your provider uses a band other than band 20 (or uses 20 and another band), then you can open up the other bands. There are several posts about doing that.

Everything you say is just false.
it is really easy
4G : 150MB/s max
4G+ : (phone connected to two 4G frequencies) 300MB/s max
4G++ : (three 4G frequencies) 600MB/s max
Xiaomi MI 5s is supposed to support up to three 4G frequencies at the same time BUT, in a lot of case, like here, in france, band 3 (1800Mhz) and band 7 (2600Mhz) are the two compatible 4G freq, BUT Mi5S Plus can't connect to 2 freq simultaneously and we don't really know the reason, in china it's not FDD LTE but TDD lte and it works, maybe it just doesn't work on FDD...
This is what we are asking to dev, find a way to enable dual or triple 4G freq in FDD LTE to acces high speed 4G.
I'm sure it's somthing to do with modem or kernel modification :S
Best regards
At the risk of starting a flame war, could you cite your sources on that?
I believe the speeds you quoted are wrong. Telus up here in Canada operates on 4G LTE version 8 which supports up to 750 Mbps max, but to expect average speeds around 200 Mbps (http://www.telus.com/en/sk/mobility/network/). NOTE - 750 Mbps is 93 MB/s approximately. Mind you, independant studies show that average speeds are closer to 20 Mbps for telus ().
Now, correcting my previous post - I was incorrect about our phones supporting 4G+. I misinterpreted the wikipedia article.
Looking at GSM Arena for our phone, it only supports LTE and thus not 4G+ (http://www.gsmarena.com/xiaomi_mi_5s_plus-8350.php). If you look up the galaxy S8+ for example, it supports LTE-A which would be 4G+.
We can read about LTE-A here - https://en.wikipedia.org/wiki/LTE_Advanced
and you can see which speeds different carriers offer here - https://en.wikipedia.org/wiki/List_of_LTE_networks
For example, Telus, which I am on, only recently added support for category 11 - 600 Mbps.
The 4G++ that you speak of I believe is LTE-A Pro (https://en.wikipedia.org/wiki/LTE_Advanced_Pro). But they are not referring to it as 4G++ but as 4.5G or 4.5G Pro.
Looking at this article - https://en.wikipedia.org/wiki/List_of_devices_with_LTE_Advanced#Xiaomi - it appears that our phones do not support 4G LTE-A. What is a little confusing is that the 5s does support LTE-A.
I could be mistaken, but I am pretty sure it is a hardware restriction to not support LTE-A.

Everything you say is just false.
it is really easy
4G : 150MB/s max
4G+ : (phone connected to two 4G frequencies) 300MB/s max
4G++ : (three 4G frequencies) 600MB/s max
Xiaomi MI 5s is supposed to support up to three 4G frequencies at the same time BUT, in a lot of case, like here, in france, band 3 (1800Mhz) and band 7 (2600Mhz) are the two compatible 4G freq, BUT Mi5S Plus can't connect to 2 freq simultaneously and we don't really know the reason, in china it's not FDD LTE but TDD lte and it works, maybe it just doesn't work on FDD...
This is what we are asking to dev, find a way to enable dual or triple 4G freq in FDD LTE to acces high speed 4G.
I'm sure it's somthing to do with modem or kernel modification :S
Best regards

After some search, Mi5S Plus is only 4G+ intraband and not with interband 4G+
I sold mi5s plus and buy redmi 5 plus better
I don't say mi 5s plus used for 4g or4gplus
I say only my phone don't getting call
Or internet in sim1 by one operator change operator in sim1 to irancell operator only have internet cannot call or get call
The problem is from www.hamta.com must phone registered in this site in Iran for use
Hello dear u should unlock all lte band for using 4g+ in iran i tested this phone in uae and china have 4g+
How can I do it? I just installed Lineage 17 and only appear LTE. I am in Italy and with a brand new P40 Pro Huawei peak download is ~150 mbps but with mi5s plus this is the best can achive.
While Qualcom specs speak of 600mbps for the X12 modem inside the Snapdragon 821

Thanks to this thread https://forum.xda-developers.com/t/guide-how-to-unlock-bands-and-5g-on-700mhz.4114679/post-84040943 and Network Signal Guru app, I know that available bands for this phone are unlocked.
Why only poor performance on this phone? How to improve them?

I really don't understand why there has been so few attention in respect of this feature so central for a modern smartphone...

There is an option to enable carrier aggregation & is enabled by default.

Kirin 970 processor present in the Honor View 10 is the Worlds first mobile SoC that supports Cat 18 LTE. It can attain maximum data speeds of 1.2Gbps. In contrast, Qualcomm’s Snapdragon 835, supports Category 16 downlink LTE, and can achieve maximum download speeds of 1Gbps.Tthe Kirin 970 is capable of aggregating up to 5 LTE (5CA) downlink carriers & phones equipped with this chipset will likely achieve even higher data speeds once carriers start supporting this technology. So basically it future proof. Even the OnePlus 5T supports only upto 3CA.
CA related question
Is there any tool, app, code to see between which 4G bands the device is "making" the CA?

The carrier aggregation option is missing from my phone, lol - B140 C432 (Europe). My OnePlus 5 had LTE-A all the time (the 4G support on my mobile provider is on 1800 and 2100 bands). Since I got the View 10, I have not seen the LTE-A sign not even once, always stuck on 4G only. A friend of mine has Mate 10 Pro and he gets LTE-A. Same mobile provider, same chipset.

I'm in America..
And it says 4g on mine all the time
But when I check the signal I get lte band 5.. And others depending on what towers I use it the area I'm in
I think maybe the indicator is inaccurate but still received lte.
Down load lte Discovery app from play.
It will tell you all the info you need.
Also depending on what theme I use the indicator will work and show lte.
Just eye candy.. It works.
