Mi 5 4G+ interband or intraband? - Xiaomi Mi 5 Questions & Answers

As for the title, does the Mi 5 LTE+ is using interband CA or intraband CA in stock ROM/any custom ROM?
Since my country carrier is using band 3 and band 7 LTE mostly, and my current carrier claim that they using interband CA (although it's still LTE CAT 4, so the max bandwidth they do support is 20 Mhz) so my Mi 5 can't use their LTE-A hmmm

Hi, what's the difference between them? Also in my country there's the aggregation of b3 and b7 and with my mi5 I have never had 4g plus..

Interband is B3+B7
Intraband is B3+B3 or B7+B7
However after I research awhile and found that Mi 5 does can support Interband CA since just now I read from Taiwan forum, both Taiwan Chunghwa Telecom and Japan NTT Docomo can use their CA in Mi 5 as the attachment shown below
And both operators are using Interband CA, their config is show below:
NTT Docomo: CA_3A_19A, CA_1A_21A, CA_1A_19A_21A, CA_1A_3A_19A and more
Chunghwa Telecom: CA_3A_8A, CA_3A_7A_8A
And as for what I search, B7 have poor signal distribution, as for my operator I'm most seeing the B3 but B7 is really seldom come out

I can assure you that b3+b7 doesn't work with mi5. I tried really hard to find out a solution but I never succeeded.
http://en.miui.com/thread-360460-1-1.html
This is a post in miui forum where other people had the same problem.. I also chatted with all the dev team trying to figure out something.. Is there something problematic with that and I don't know what it is.. (b7+TDD frequency bands works)

But then with the Taiwan Chunghwa Telecom, their band is all FDD band, why in some post they reply it still can detect LTE+?

I honestly don't know, during my searches someone said to me that the problem is the kind of the spectrum (continous or discontinous). Don't ask me what does it mean cause I don't know.. Maybe this is nothing but that's the only answer that I found.. I tried with 3 different phones and I got the 4g plus, with mi5 no 4g plus. I tried all roms (china, global, third part roms) no 4g plus.. Just with b3+b38

Just now I'm also found that the spectrum distribute by my current carrier is also kind of hairwire, inside the house they are almost all B3 while when go to outside the house hey are almost all B7
This is kind of weird, and according to some forum they tell that my current carrier is really doesn't display 4G+ in major phone as they using 10MHz+10MHz (CAT4) which results some phone may just detect it as 4G signal

No way, that's not possible cause I checked with lte bands and I also checked the band used and I know for sure how much Mhz my carriers use in my country and that conclusion is not possible. I also have proofs that mi5 has no problem in detecting 4g plus as the sum of more bands with photos of lte bands logs.. I think that this problem is underrated and I found just few people to talk about it

I got some news, A friend of mine said to me that intraband is the sum of near frequencies (such as b7 and b38), this kind of aggregation is possible in every condition. The interband aggregation (such as b3 and b7) needs a chip called companion that helps to sum the download of distant bands (b3 and b7). Probably the mi5 does not have this kind of chip and so the only possible CA is the one with near frequencies.. I also tested it and it works. I don't know how to confirm this anyway but it makes a lot of sense.

[Q] Activate band 20 on xt1058

Hi,
I recently purchased a new xt1058 on ebay, it's the US model i belive, but LTE doesn't work in france.
xt1058 have 2/4/5/7/17 bands activated and LTE in france is 20.
Is there any way to change that ? Can I switch modem files from xt1052 rom (EU version) ?
I'm running kk 4.4.4 212.44.26.ghost_row.RCI.en.CA version.
Thanks!
According to this:
http://en.wikipedia.org/wiki/List_of_LTE_networks#Europe
France carriers also use band 7 (along with 20). So if you have the proper carrier, you should be fine.

I think the problem is that LTE on band 7 is only on 2600MHz, only band 20 use 800MHz in France
There are 2 different bands mate. One is 2600mhz and the other is 800Mhz. According to Wiki, there are carriers in France that uses 2600Mhz as frecuency for LTE. If that's the case, you should be fine. Look at the link I pasted before.

The problem is the moto x use only 850/900/1900/2100 frequencies , not 2600 MHz.

Those are the 3G bands that the Moto X supports. Not LTE bands. You are confusing things here.
XT1058 uses LTE bands 2/4/5/7/17 (look here http://en.wikipedia.org/wiki/Moto_X_(1st_generation)#Variants)
Hence, it uses 1900/1700/850/2600/700.
Many carriers in the EU use band 20 in most cities, the official reason is, band 20 covers more area and only band 7 is used in cluster areas, such as football stadiums, airports, central train stations etc.
At least thats what the German carriers say.
So its mainly an economic decision to use band 20 for regular urban areas and only use band 7 (which doesn't cover so much km²) in the cluster areas.
There is a user who is currently editing some files to enable software wise other LTE frequencies for the Droid, have a look here: http://forum.xda-developers.com/droid-turbo/general/droid-turbo-conquers-europe-t2995343/page3
This however, will only enable the LTE bands software wise, it hasn't been tested yet, if the LTE works then in the EU for band 20 or if its a hardware limitation or if you need to flash the EU modem, too

I have since months xt1052 fw with 1053 radio and this allowed me to have Italian language and 3G/H+ working fine. xt1052 radio don't work at all on US devices.
Tried last week to enable bands modifying NV strings via QXDM but there's not effect. GSM and WCDMA are good, but no LTE. I guess is hw limitation, or some other NV items must be changed to get it working.

Ok, thanks for the clarification
By the way, there is a nice wiki who talks about french LTE bands, and according to it, band 7 @2600Mhz is used by 3 carriers, including mine, but no LTE on my moto x...
As Dagoban said, carriers must mainly use band 20 @800mhz to cover large areas.

Has anyone tried enabling bands with QPST?

I have a question for all the lucky ones of you who have a Mi Mix.
With most of the Xiaomi phones which are released, people are unhappy about the lack of band support for regions outside of China. I know many people in Europe are unhappy about not having Band 20, those of us in Japan would really like to have UMTS Band 6/19 (among others), Australians want LTE Band 28, and people in the US would like Band 12/17.
As you may know, with some phones, it's possible to unlock these bands by putting the phone into diag mode and using Qualcomm tools like QPST. Here in Japan, it was possible to enable the UMTS Bands 6 and 19 on the Mi5 and the Mi Max, but not possible on the Redmi Note 3 or the Mi5S, so it's really case by case.
Seeing as that the Mi Mix is a concept phone people are crazy about all over the world, I am very curious whether it's possible to enable LTE bands and WCMDA bands on the Mi Mix. I don't want to spend the big money to buy one without first having confidence that I can get it to work on my carrier's bands.
So I'd like to start this discussion. Has anyone tried anything? Successes, failures, please post them all!

This (QPST) is something I have no experience with,but,interested in the subject:
I'm good with the band support (for now) as what's available in my area,with my carrier,is supported (Bands 2 &4 on T-Mobile US,no Band 12 or 66 yet),definitely would be nice for at least Band 12,if possible,as I believe my area will get it eventually.
One side note & a positive one at that:
My MiMix locks-in on a signal & has better/stronger connections than any phone I've used to date. This was really noticeable while commuting back & forth to work today,unbelieveable signal quality.
IDK if the ceramic body is better vs other materials,but,recent flagships from HTC/Samsung/LG pale in comparison vs this phone.
i have MI MIX in hand.
I think we need MIX Diag Driver to make it recognize from pc. MI5 Diag drivers are not the same

I've heard the Mi5 diag drivers were usable on the Mi5S, which is the same SD 821, so that's strange. What happens when you put it in diag mode and plug it in? Can I see a screenshot from device manager, or some evidence of what the device is?

I've got one in hand in the states (where I actually do need to unlock band 12 for T-mobile) and a patch cable I made handy in case this thing goes brick mode from us trying stuff, I'm game to be the guinea pig for science.
Fair warning though, while I'm a web developer that's very comfy with terminal, I'm new to the android ADB world, so pretty detailed instructions / links to guides will be needed ha!
Good luck Ken, I hope you are able to crack this bad boy.

this is what I have gathered from various sources (so yes Band 4 is both LTE and 3g)
Tmobile
LTE Frequencies:
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2
Lower 700 MHz band 12
3G/4G Frequencies (WCDMA):
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2
2G Frequencies (GSM/GPRS/EDGE):
1900 MHz PCS band 2
ATT
AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands
LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz),
Band 4(1700/2100Mhz)
LTE B29 (700)
LTE B30 (2300 WCS)

Yes....was just giving the bands and frequencies I know for two GSM carriers in the US. Monitoring the bands at various locations by something like signal check lite (much easier to use/read than lte discovery IMO) would be only way to tell.. If I recall correctly this device has 3g at 850,900,1800,1900 so there is no band 4 on 3g it seems... Although band 4 (1700/2100) COULD be a 3g band too for some devices. Someone with better knowledge can chime in here. I might be wrong.

Update: I have actually successfully forced band twelve with NV values (I can see it stick and unwind the value to see that band 12 is allowed after a reboot). I followed about 10 diff guides to get my bearing on working with the Qualcomm editors and maintenance programs.
Sad to say: the modem in the Mix simply won't do band 12. I talked with a few folks from the Xiaomi Reddit Discord and they confirmed my suspicions that with Xiaomi (with a few exceptions) it is usually hardware that's keeping you off of a band.
I don't personally think there's any amount of software hackery we can do to get bands unlocked.
Edit: I am quite comfortable in ADB / SU and am happy to try any and all suggestions out on my phone in addition to what I've tried already btw. Please do let me know if there's something you think I may have missed following the various unlock threads.

Sorry to hear that the band could not be tapped into...
yes most likely a hardware thing-like Samsung (some of their models exclusively for Latin america have u.s bands but the 'international' variants of the same models will not do the U.S bands no matter what...
I actually opened one of them (got a damaged T239M) and found indeed that the motherboard is different...(so much speculation and folks asking/trying to flash S. American firmware on like the T705, T239 etc, myself included (not possible anyway even if going through TWRP and flashing modem files etc...bootloader and pit all different..so nothing would change with the other parts of the firmware)
so it is highly likely in this case that the modem will not do bands 12, 17 (ATT) and 29, 30 (ATT). However, it is impressive that for a China phone this will even do bands 2, 4 and 5. Huawei models (again supposedly international) except for some variants of the smaller 5-5.2 inch models (not p9, p8, P8 max, x2, t3, t3 pro, or m3 (some of these are the tablet phone types) and numerous other Chinese phones will not do anything more than 1, 3, 7 and then maybe 8 and 20 or a 28. (all useless for North America). Huawei has an M2 variant that has US bands and also on their smaller phones (certain versions)
so for the Mix, you at least have LTE 2, 4 and 5 (though of lesser importance).

I would love to, it's the first thought I had when both starting a new guide and when I finished getting the phone to look for band 12.
I'm currently _buried_ in a project for work right now (it's taking my nights and a lot of sleep from me ha), so nothing soon. But it's on my list of first contributions I'd like to make to this awesome community!
Would you be able to try Band 20 ?

So far my experience is that if the band isn't listed in those spec sheet it isn't there in the hardware (apparently a very Xiaomi thing to do). I'm finding that they rarely software lock you out of the bands, it's usually that their hardware simply doesn't support the band.

Will the A3010 work well in Europe?

I'm about to buy a OnePlus 3T.
I live in Sweden and travel in Europe from time to time.
Will the A3010 work well for me (even with 4G)?
I have already looked at willmyphonework.net/ but it only says:
"Device is compatible with some of the network carriers frequencies. It may work."
What practical advantages would I notice with a A3003(European version) vs the A3010(China version)?

I have already looked at willmyphonework.net/ but it only says:
"Device is compatible with some of the network carriers frequencies. It may work."
What practical advantages would I notice with a A3003(European version) vs the A3010(China version)?

The main difference between OnePlus 3T A3003 and A3010 is the A3003 supports LTE band 1/3/5/7/8/20/38/40, which is the international model while A3010 supports LTE band 1/3/5/7/8/38/39/40/41, which is the China model.
basically you wont have support for this bands on 4G

The only LTE band that is missing on A3010 is Band20. Most of Sweden network carriers are using Band7 so you are good to go. When you go aboard is a different story. But you are also more flexible because you can chose the roaming network. All you have to do is to chose a supported network carrier.

I'm confused by this. By those numbers it seems that the China model covers all the numbers as the Europe mode,l plus a few more. If so, then what bands are missing?
Or doesn't it work that way? Please help me understand
Edit: Oh... I missed to see band 20. But what does it mean practically that the China model misses band 20? How will I notice it?

Okay. What does it mean practically that the China model misses band 20?
How would I be likely to notice it when using my phone?

On a network that is using Band20 you'll have only HSDPA connectivity. Basically the phone will work just fine except the fact you won't have LTE connectivity. You'd have only 2G/3G/H+

Thank you. It's getting somewhat clearer. Okay, but how likely am I to run in to Band20? Is that band (the only one missing from China model) more likely to be used than any of all of the other bands that are listed?

I'll give you the UK example. In UK there's 3 LTE bands in use: 3,7 and 20. Other put 2600Mhz, 1800Mhz and 800Mhz (that's Band20 btw...). Only O2 is using only Band 20. All other providers are using at least one extra LTE band. EE is using all three LTE bands, Vodafone is using band 3 and band 20 and Three is using band 7 and band 20.
Now here is the thing... Those network checkers are telling that your device might work. But is not always the case. Here is the Vodafone UK example. As I said they are using Band 3 and Band 20. Now let's take a phone with Band3 but not Band 20 (for example my former Xiaomi Mi5). Will work on LTE but only in urban areas. Why? Because in rural areas the band used are band 7 and 20. Why? Lower frequencies are better at travelling long distances so are more suitable for rural areas where there are fewer masts. Also Band 20 provide better indoor coverage. But if you live in an urban area Band 3 and 7 are more likely to be used. The higher the frequency means higher capacity and therefore the ability to deal with more users which is a must in an urban area.
All in all the best way is to call your provider and ask what frequency they are using in YOUR area. If they are using 1800Mhz or 2600Mhz you are good to go. If not...I'm sorry.

Just for my curiosity why are interested on a China version and not on a Europe one?
Here is the list of LTE bands used by Sweden network carriers. Take a look at it and you'll see if China version is good to go on your provider.
If you're primarily going to use it in Sweden, I would go with the A3003 (that's what I did, but then I seldom leave Jämtland ?).

Wow. Now that was a good response! You really seem to know your stuff! Cool. :good:
Okay. Now I understand things a lot better too.
I use Telenor (and spend quite some time in Jämtland (rural) like another poster here:good.
Well I plan to buy my phone on ebay and the annoying thing is that the A3003 is about $100 more expensive than the A3010. I still think it is hard to decide if it will be worth an extra $100 for the Europe version...
You should not only consider LTE Bands, but also consider LTE CA.
Hong Kong/ Europe Model (A3003)
FDD-LTE/ 4G: Bands 1/3/5/7/8/20
TDD-LTE/ 4G: Bands 38/40
LTE CA / 4G+:
B3+B7, B3+B8, B3+B20, B7+B20, B3+B3, B3C, B7+B7, B7C, B40C
China Model (A3010)
FDD-LTE/ 4G : Bands 1/3/5/7/8
TDD-LTE/ 4G: Bands 38/39/40/41
LTE CA/ 4G+:
B1+B3, B39+B41, B39C, B40C, B41+B41, B41C,B38C
American Model (A3000)
FDD-LTE: Bands 1/2/4/5/7/8/12/17/30
LTE CA/ 4G+:
B2+B12, B2+B17, B4+B7, B4+B17, B12+B30,B2+B2, B2C, B4+B4, B4+B12, B4+B5, B2+B5
Ok. I ended up buying the EU-version as I found one that was just $40 more expensive.
Many thanks for making this more understandable guys! *thumbs up*

India 3T - 4G/LTE not working in US

Hi,
I bought an one plus 3T in india and brought it to US. I'm getting only E not even 3G. When I enquired in T mobile/lyca store, i was told that india unlocked mobile won't support the US bands. Network upgraded. It was big surprise to me. Please suggest me how to unblock additional LTE bands in my 3T mobile.
That's not possible, you should trade your 3t A3003 for a 3t A3000 American band-unlocked model.
Check the specifications for each model under connectivity.
https://oneplus.net/us/3t/specs
Wait, what?
I live in Sri Lanka (Tiny country below India) and my 3T is the Indian device. I toured Europe for 2 weeks, and I used an O2 Sim, and used LTE in Europe for the whole time I was there. Have you tried going to Settings, and selecting "LTE/3G Only"? That may fix your issue.
I swear, there should be no issue with the bands.

India uses FDD 850, 1800 and TDD 2400. Most of the Europe uses TDD 1800. So you getting LTE in Europe is not a surprise.
USA uses 700, 1700, 1900, 2100, 2300
Varies with MSP
You will at least get 3G with T-Mobile and AT&T

Europe and india uses the same bands. I lived in uk and used the uk phones in india and indian phones over there. Its the states that uses different frequencies so most of phones don't work properly outside states.

Compatibility of phones with the cell networks in the US are a total pain in the you-know-what. We have 4 different major carriers, all using different bands (a little bit of band sharing, but most completely different) for 3G and LTE (GSM is a little more standardized thankfully). Basically, as a general rule if a device not intended/designed to work on US (and depends on which exact US carrier), you are probably going to run into some incompatibilities (no 3G or no LTE, or limited connectivity).

Talk about synchronicity eh? But do the difference in bands give any speed differences, or call clarity? In the blind about these stuff, coming from a country that has only one carrier out of five who is still beta testing VoLTE.

Not an expert, and had to Google that. From what I'm reading, lower frequency (MHz) has better penetration (through buildings, etc.) while higher frequency bands have higher data capacity.
There are steps on how to unlock additional bands. There are like 50 steps. I dont remember where I've seen it but if you google how to unlock bands on OnePlus you will find it. Also try to flash Oxygen OS from US web site which I see no reason to work but just a suggestion lol

There are no region specific versions of OxygenOS, so this will do nothing but reflash the latest update.

There are no steps at all. You cannot "unlock" bands, as they're hardware related. There's no way to switch bands out of the blue.

At one time that was true. But for Qualcomm SoCs, the band support stopped being set in hardware (at least for the most part) some 3 years ago with Snapdragon 801 (or maybe earlier, but definitely with 801). Support for all or most bands (might be some exceptions) used worldwide is there, but the specific bands are enabled in firmware.
https://www.qualcomm.com/products/rf
That said, enabling bands is a long process as noted; and has the risk of resulting in a radio brick. So it's best to buy the correct region version OP3T (which supports the needed bands out of the box) when possible.

Why aren't all bands just enabled by default then? I don't understand why there are different models for different regions.
I have a US OP3T and I'm visiting India. It''s working with Jio in India (although it supports only only of the 3 bands used by Jio) but VoLTE doesn't work for some reason.

Will K20 Pro work in NZ?

I'm a bit confused, they are going on about the 9t Pro coming out for Global market, but on Aliexpress there is a K20 Pro with 'Global Rom'.
If i was to buy one of these would it not work in New Zealand? I'm really keen on getting this phone but not sure what to buy.
According to this, it works perfectly with my provider 2Degrees

The K20 Pro does not have global network bands. Where it's sold with a global ROM, these are unofficial global ROMs, they do not and cannot add extra lte bands.
The Mi 9T, as well as coming with an official global ROM also had a few extra lte bands unlocked. The Mi 9T Pro will do the same, when it eventually arrives.
Looking at your carrier, it uses bands 3, 7 and 28 (maybe 40 too, but could have been a different NZ carrier). The K20 Pro is missing band 28.
Band 28 is a relatively low frequency band, these can travel further and penetrate obstacles better, before losing significant signal strength and quality. Quite often the low frequency bands are used in rural areas, where masts are spread widely, or major city centres that are very heavily built up.
NZ is a very sparsely populated country, so it's possible band 28 is heavily relied on outside of the town's and cities. But this is only my slightly educated guess. I would suggest doing some more homework on how much of the 2Degree network relies on band 28.
I imagine in and around towns and cities you'll have very little issues, but that's a small percent of the country.
Assuming the Mi 9T Pro will have the same bands as the Mi 9T, then it will come with band 28

It says that 2degrees doesn't use B28, only other carriers in NZ. So that would mean its safe to assume it would work?

I checked on Wikipedia, however I was looking at the bands for Spark by mistake. 2Degrees uses 3, 8 and 28.
https://en.wikipedia.org/wiki/List_of_LTE_networks?wprov=sfla1
Band 8 is on the K20 Pro and is also a low frequency band. So it could well be that it will work OK. However it is showing that band 8 was added to the 2Degrees network only last year, so might still be wise to see if you can find out how widespread band 8 is used on their network.
Edit:
A bit more reading. The 2Degree website FAQs confirms it uses the above 3 bands. Band 8 was previously used for their 2G network, but was freed up when they turned off 2G, which allowed them to use it for LTE. Maybe that will mean it's use is widespread.
I'm not sure about nz but it works perfectly fine here in Australia. The only band we use in Aus that it's missing is B20 which is very common. But fortunately if you're with Telstra in Aus they don't have any areas that only run on B20 so there's always something for me to connect to. I also live in a rural area.
So my advice is to check different areas all over nz to see what they support. I used a site called cellmapper to do this https://www.cellmapper.net

Australia use band 28, not 20.
Global version and chinese version are using same 4G bands so there won't be any problems.
