Hi all
Thanks in advance for any help please provide links if possible. So I've finally stopped waiting for Nokia and then Nokia/Microsoft to get their act together and jumped on the android wagon. It seems android has everything I'm looking for (sync to outlook, office document viewing editing, etc not Garmin yet though).
Anyway I've been doing research on the Samsung galaxy s2 and found some discussion on the 3G modem/antenna being penta band. Is this true? If so can I get links, also how do you enable all the bands? Or can you enable those bands that pertain to the firmware and have to keep the other bands on the phone so if you need them you can flash.
Side question I played with a korean S2 and saw that it has NFC on the apps (out of the box). I'm pretty sure this is true but I'm having some doubts as the FAQ and some other forum member claim that no current S2 has this feature.
Thanks
It's quad band 3G. 850/900/1900/2100. It does not do 1700.
From Samsung.com:
Quad band GSM 850/900/1800/1900
Quad band UMTS 850/900/1900/2100

As for NFC, the I9100 does not have it. I'm not sure if any of the other Asian models (different model numbers too) have it or not.
I heard that the modem intel x626 gold is penta band (unconfirmed) that is in the galaxy s2. Also the tmobile version is coming out which has 1700mhz this might lead me to believe that it is penta band in hardware and only needs software.
Only the korean version of the s2 has NFC.
No other version has it as cell phone providers are thinking of releasing it attached to the sim card as soon as the technology has stabilized and is widely available in a number of countries.
here is some information about in this blog.

the sd card sounds like a good idea as a aftermarket part but I thought I saw the SGS2 with NFC on ebay as the I9101. what would happen if I had to add extra memory to the phone?
Duplicated
I emailed Brian Klug that did the review of the SGS2 on Anandtech.
http://www.anandtech.com/show/4686/samsung-galaxy-s-2-international-review-the-best-redefined/
It is one of the most in depth that I have seen but here is what he says about the SGS2 being penta band.
"XG-626 is compatible with more bands, however the limiting factor always is whether the device manufacturer has provided the power amps for those other bands, and in this case there aren't more."
Since Nokia does clearly say everywhere else except the US that 920 does support 1700Mhz (for obvious reasons), I wonder if the hardware in the AT&T version will be the same as in the int'l version and it'll just be a matter of unlocking the phone to use it on TMo.
Opinions?
I noticed that too!!
Its now PentaBand WCDMA/HSPA+ at 42Mbps. They added WCDMA 1700Mhz band on the specs.
Originally when the phone was announced last month was listed as QuadBand WCDMA missing the AWS band at 1700Mhz.
If this is true it means one of the following:
1.The band was always there and for some reason software locked and they decided unlock it and release it as a PendaBand.
2.They listen to the complaints (pretty much the same way they did and released the Cyan Color) as the missing AWS band was one the biggest complaints especially from T-Mobile USA subscribers and they decided to include it as well.
3.It is just a typo and Lumia 920 is still QuadBand HSPA.
4.It was a typo from the very beginning and Lumia 920 was always PentaBand.
Now assuming the the phone is PendaBand HSPA+ it will perfectly work with T-Mobile USA current 3G at AWS and with the reformed Network at 1900 they are preparing. It will work with both at 42Mbps speed.
The original unlocked Lumia 920 listed the following 5 LTE bands 800 / 1800 / 2600 / 900 / 2100.
If the unlocked phone comes with those LTE bands will be incompatible with T-Mobile USA upcoming 4G LTE network.
However the American model which AT&T will carry exclusively has the following LTE bands 700 / 850 / 1700 / 1900 / 2100
If Nokia also release an unlock/unbranded version of the American model with the above LTE bands and PentaBand HSPA+ this model along with the 42Mbps HSPA will also support T-Mobile's upcoming 4G LTE that coming mid of next year with theoretical speeds of 100Mbps.
Releasing this device will be the perfect option for T-Mobile subscribers as it will be future-proof for their upcoming LTE network.
I am curious to see whats really going on here. Meanwhile I am crossing my fingers. :good:
So Nokia needs to release a international us version?

Unlocked/Unbranded version of the American model is the correct way of putting it.
Nokia used to have to versions of the unlock devices in the past. The regular version which was usually the European/International model and the NAM versions for North America.
Many devices came like that in the past including the N95 & N95 NAM, 5800 & 5800 NAM, N97 & N97 NAM etc.
All had QuadBand GSM and different bands for 3G, the NAM versions had the American bands for AT&T USA and Rogers for Canada.
Now that PentaBand is standard for 3G/WCDMA, they need to release (and I hope this is the case) the European Model with the European LTE bands and a "NAM" model with the American LTE frequencies.
I guess time will tell what exactly the case is going to be.
But again this is for LTE. Assuming that the information on the spec-sheet is correct and the Lumia 920 comes with WCDMA/AWS 1700 then it will work perfectly with T-Mobile USA and AT&T's HSPA+ at 42Mpbs.

Unfortunatly number 3 is the correct answer.
According to WPCentral.com the AWS 1700Mhz WCDMA support for T-Mobile 3G that listed in specs are just a typo on the website.
If this is the case, you can still use the Lumia 920 under T-Mobile 3G at 1900Mhz.
T-Mobile is reforming their Network and releasing 3G to 1900Mhz now, the problem is that we do not know what markets/areas has this already or how fast the project is moving on and when it will get complete..

That's wrong, because this phone will be using the Snapdragon S4 Plus (MSM8960) which uses Software Defined Radio (SDR) for determining their bands. Obviously you cannot use all at the same time, but any one at any time. The HW supports this (according to the Qualcomm reference design), and if it hasn't been supported before in this chipset, it's probably due poor modem programming and/or unstable behavior, and/or band/bandwidth throttling by service providers networks. It's also an efficient way to make sure your Verizon mobile cannot use AT&T networks and vice verse...

That is why I said its Number 3, according to WPCentral. I am aware of the SDR in the latest generation of Snapdragons, however as its name mention its programmable, meaning they may have turn off the AWS...
For me it doesn't make any sense to list the phone originally with QuadBand WCDMA and then add AWS and list it as a PentaBand.
I mean if it is wrong and its missing the AWS that is making the original listing with QuadBand the correct one, so why they bother changing it?
In the other hand if the SDR scenario applies and the AWS is already there, they may just heard the complains and simply turned ON the AWS band, that is why they added in to the specs meanwhile the Nokia representative that WPCentral reached may not be aware of the new specs yet...
All these are different scenarios, unless we have an official clarification from Nokia, we cannot know for sure until Lumia 920 its been released.
PS. Can you post the link with the detailed specifications of the Snapdragon S4 detailing the SDR? The specs I found does not include any information regarding this. If I am not mistaken and remember correctly SDR is affecting LTE only and its able to catch from 700Mhz - 2600Mhz (for LTE), its programmable to deliver everything between these bands but limited to deliver 5 Bands at a time. I do not remember mentioning WCDMA to be compatible with the SDR, but I may be wrong on that. Please feel free to correct me if that's the case.
According to FCC documents, looks like AWS is there. Question... Will it be disabled in the AT&T version? Unlock possible?

I read that the FCC Documents for the AT&T model are mentioning AWS (1700) for LTE. This is normal as AT&T's LTE is operating also in AWS.
I didn't read anything regarding AWS for 3G/WCDMA.
If you read back, it specifically mentions wcdma 1700. Document differentiates between lte freqs and wcdma ones.

Has anyone tried using one of the white unlocked Lumia 920 from Clove (I guess the ones from Expansys are the same) on an LTE network?
Specifically, do you have the "4G" option in the "highest connection speed" settings?
In my case, although I am using an LTE SIM with an LTE network on a supported band, I only have "2G" and "3G" options in the Highest Connection Speed settings. So normally it is only connecting over HSPA. Through playing around a lot with scanning LTE bands with the Field Test tool (##3282#), I can sometimes get the device to connect to LTE, after which it works perfectly on LTE until reboot. But it's not really a long-term solution.
The default firmware on my device is country variant "CV GB SW Variant ID 276 v03" which (apart from the version number) seems to be the same firmware as that sold by Orange / T-Mobile in the UK (i.e. for 3G networks).
I was thinking about trying to flash the EE firmware, but concerned this could create other issues (such as end up locking the phone to EE, or to certain LTE bands, or something...). Any thoughts appreciated.
You don't mention where you are, but that might help respondents.
As you may know, the LTE bands are different between the NA and Europe. The LTE Bands listed on the international version are 800/900/1800/2100/2600 while the NA(Rogers & AT&T) version has 700/850/1700/1900/2100.
Are you sure you are connecting to the LTE bands? Do you have an LTE SIM installed?

Have a look at this offivial Blog post from Nokia.
http://goo.gl/L2eiy
They basically saying that even-thought the new Lumias are LTE ready they will required a software update to turn LTE ON.
The information on that is very limited as Nokia didn't specify ANY details on how they will push this OTA.
What happens if you have an unlock device and use it in a different country of its origins? How they will push the update under what criteria?
Is the update is driven by the SIM ID? They will update the OS and turn ON LTE depending the SIM region or the device IMEI region?? Nobody knows...
Even worst there is a rumor that the latest Snapdragon S4 is supporting all 9 LTE bands at ONCE and the software just enable the appropriate ones, its programmable from the firmware. If this is true, then Nokia is committing a suicide here, they can simply program WP8 to recognize the SIM ID and turn ON/OFF LTE Bands depending the Network. Going with OTAs across different devices and regions will be a mess.

There are international versions that HAVE ALL 9 LTE bands enabled and also petaband 3G.
For example in Germany:
http://www.nokia.com/de-de/produkte/smartphones-und-handys/lumia920/technische-daten/ (expand where it says "Basisdaten")
or in Singapore:
http://www.nokia.com/sg-en/products/phone/lumia920/specifications/ (expand where it says "Hardware")
or also in Switzerland:
http://www.nokia.com/ch-de/produkte/smartphones-und-handys/lumia920/technische-daten/ (expand where it says "Basisdaten")
I think there might be a good chance that you can unlock those extra bands on international versions (RM-821) that have them disabled by flashing a different firmware version. However this is just me thinking out loud so please don't blame me if it doesn't work or if it breaks your phone!
However I would strong discourage you from flashing an RM-821 firmware to an RM-820 (North American version) as I know that sb around here almost broke his phone by doing so.
Hi all
Thanks for your replies so far.
Right now I am using the phone in Japan, where there are three carriers with Band 1 (2100 MHz) LTE networks. I only tried one carrier so far, and yes it is an LTE SIM. As mentioned, I can actually connect to LTE and have used it for several hours, it's just necessary to use an unreliable trick (with ##3282#) to get the phone to see the LTE network. This seems related to the fact there is no 4G option in my highest connection settings.
Thanks for the heads-up on the OTA updates, agreed it's not clear how this will work at all...
Regarding the LTE band support, personally (although it's just my intuition) I think the lists of 9 LTE supported bands on those regional Nokia websites are probably in error (it wouldn't be the first time). Normally the most reliable source in Nokia's website is Nokia Developers, which clearly shows five bands for global RM-821 (1, 3, 7, 8, 20) and four bands for AT&T RM-820 (2, 4, 5, 17).
While the Snapdragon baseband may be able to support all 9 bands, the most difficult part of the design is the RF - filters, amplifiers, etc. So I imagine different RF chains are used in the two variants to support these specific bands.
Again, if anyone has the unlocked RM-821 and tried with an LTE SIM, if you could confirm if the 4G setting is available in highest connection settings, it would be much appreciated.

I thought the same thing on PentaBand 3G and 9 Bands LTE, however in another discussion we verified (at least for the German model) that even thought the Nokia German website states PentaBand 3G and 9 Bands LTE, in the retail Box it only mentions QuadBand 3G (AWS missing) and PentaBand LTE.
With the Canadian model being PentaBand and Snapdragon's S4 Specs claiming that is fully supporting it, along with the programmable LTE, we really have no clue of whats really going on until Nokia, or anyone else clarify it...
I have a very bad feeling that the all 920s are PentaBand 3G and support all bands of LTE with programmable software but Nokia for some reason is locking specific bands on specific models/regions.
Hopefully in time we will clarify everything and hopefully its sooner rather than later..

Different frequency bands require different antenna design. It is probably very difficult to design an antenna that can satisfy all LTE bands even though the chipset can support it. So, instead, Nokia is probably going to selectively make different hardware with different antenna design to fit a specific region. Apple iPhone 5 uses the similar Qualcomm chipset and it only supports very limited LTE bands for international version.

For 3G PentaBand is now standard in almost all chips and since the Canadian variant comes with PentaBand on board and the fact that is standard on the S4 I really see no reason of why Nokia will order a custom version of the S4 to just physically take off the AWS. It doesn't make any sense, so if its missing, most likely is turn off in firmware.
For the LTE. Qualcomm introduced a revolutionary technology called Software Defined Radio or simply SDR and the Snapdragon S4 Plus MSM8960 chip which is inside the Lumia 920, supports that technology. With SDR the chipset support all LTE bands from a low to high frequency, it can work in everything between, of course not at the same time, the software programs what frequency the antenna should be set.
If the Lumia 920 and its S4 really have SDR technology, they it will make sense for Nokia to have the firmware deride what LTE to make available to the user, by reading the SIM region and not providing individual updated per region, or based on device product number.
This finally solves a major issue for the manufactures because they do not have to build customs chips for specific countries, the software simply programs it. If you Google it you can find a lot of info regarding SDR. Of course we are not in the engineering team of the Lumia 920 line and its obvious whatever we say here is based on theory and specs that are available to us.

If you understand radio technology at all, you should know the most important part that make all things work is the radio antenna, not the chipset. The chipset itself can't receive or transmit radio signal without a proper antenna. Try to disconnect your car radio antenna and see how many stations you can receive

We're going a bit off-topic from the thread here, but you're right - SDR defines the baseband, not the RF components.
If you look at Nokia's FCC filing for the RM-821, you can see it has two cellular antennas ("main" and "MIMO") for each of two bands ("HB" high-band and "LB" low-band). Presumably LB is used for bands below 1 GHz or so, while HB is used for bands above. So you can see it's not necessary to have different antennas for every band - bands 1 to 4 (including AWS) could also use the same antennas, for example.
However, each band needs its own RF filters to prevent interference from neighbouring channels, and also needs amplifiers that have flat gain over those bands. These RF components are usually band specific, relatively bulky and expensive, and there are some challenges to use several RF chains in parallel. To my understanding these are the limiting factors that explain why a given device tends to support maximum 4 or 5 LTE channels.

Is that a joke?? I am spending my time explaining what SDR is and I am getting that respond??
I am assuming that I am talking with a person that knows at least a modern chipset like the S4 package contains all the antennas for GSM/WCDMA/LTE a separate antenna for Bluetooth and Wifi, GPS (S4 also includes GLONASS), the CPU and the Adreno GPU.
All the above come in the same tinny chip that in the size of your nail. And all this is called the "chipset". Qualcomm does not use a separate antenna anymore its integrated to the chipset.

With respect, that's not right - the antennas and RF components are external to the chipset.
Go and get the SAR compliance test report for Nokia 920 from the FCC's website, and you can see diagrams showing the external antennas for cellular, WLAN/BT and GPS which are positioned in various places inside the phone's chassis (btw, the LB MIMO antenna is about 7 cm long!)
Or go and check out the iFixit teardown for iPhone 5 and you can see the same kind of thing...

That is correct. Many manufactures are placing antenna extensions and putting additional GPS censor in more practical areas.
The actual GSM/WCDMA/LTE modem WiFi, Bluetooth and GPS for Qualacom solutions are placed inside the chipset.

4g / LTE

Likely they are LTE bands (e.g. band 5 = 850 MHz), but as you probably noticed they don't completely match with the LTE band support of the device. Keep in mind this field test program was probably thrown together by Nokia's R&D guys for internal testing only (not for consumers), so could be a legacy of earlier testing, another device variant, or some other reason...
Anyway, it seems fine to keep this setting on Automatic.

Hi Doug, could you share what version of the Lumia 920 you have, and which firmware?
As mentioned in my mail above, there seems no problem to leave the 4G band on automatic, and the bands available to be selected don't seem relevant. (My device picks up Band 1 LTE networks even though band 1 is not in the list).
Regarding 4G vs LTE, my device (unlocked UK CV) shows 4G in the top left when it is connected to LTE. I assume this can be changed by Nokia depending on the operator's requirement (esp in the US where 4G means HSPA...). You can be sure you're on LTE by going back to the field test menu, selecting GSM option, then looking at "Radio Access Technology". If you're on LTE, it should say LTE there.

Likely they are LTE bands (e.g. band 5 = 850 MHz), but as you probably noticed they don't completely match with the LTE band support of the device. Keep in mind this field test program was probably thrown together by Nokia's R&D guys for internal testing only (not for consumers), so could be a legacy of earlier testing, another device variant, or some other reason...
Anyway, it seems fine to keep this setting on Automatic.

I've kept mine on all automatic and i have noticed it switch to 4G at times, but then when i go to use it, it'll flick back to 3G... I'll need to test this in CBD sometime this week.
I got my device from clove, but im in Australia on Telstra 4G network. They use 1800mhz.

Hi, yes better to test in CBD where there's strong LTE signal.
In your Settings => Mobile Network, do you have a "4G" option under "Highest connection speed", or is it 2G and 3G only?
