Why doesn't the Tegra3 One Xhave LTE?

So I tried searching why the Tegra3 variant doesn't have LTE and the answers are more like "because the lte radio isn't compatible", I'm wondering why exactly is it not compatible?
Same goes for the SIII, it also has a LTE variant(Dual core) and a quad-core chip without LTE.
Its not like I'm suffering from the lack of LTE, its just curiosity.
Anyone ?

qualcomm LTE radio isn't and qualcomm wasn't helpful to Nvidia to integrate it with Tegra
so Nvidia had to make an LTE radio on its own hence the imminent Tegra 3+

Qualcomm wasn't helpful about it to Nvidia? Wow okay. So I assume the current LTE radios are by qualcomm only then.
Found a link explaining the snapdragon(in the lte variant of one x and s3). It includes everything basically, the processor, radio, etc. The Exynos Quad and Tegra3 don't include a LTE radio.

From what I've read till now, people seem to be more happy with the dual-core S3 than the dual-core one x. Anyways Tegra3+ ought to fix that, its actually gonna be phone raping everything then lol! LTE, higher clocks, less nm manufacturing?

not most likely it will not be an nm shrink
Today, NVIDIA announced that their Icera 410 LTE modem has been approved for use in tablets and clamshell devices on AT&T’s network. While that does not mention smartphone use yet, this is a step towards LTE and Tegra 3 coming to the States in at least some form. As we have documented plenty of times, NVIDIA has been unable to pair its quad-core mobile processor with LTE because its biggest competitor (Qualcomm) is the only guy making LTE modems at this time and likely does not feel like sharing. With today’s approval, this should bring NVIDIA up to speed in no time (assuming they get the smartphone approval too).

I wonder if they'll do something like what Apple does and offer a subsidised trade-in for T3 HOX to T3+ HOX.

I don't think HTC can afford to, however much I would love to be able to

Exynos vs Snapdragon

I got involved in a discussion in another forum that's turned into why the North American Galaxy series has a Snapdragon and not the Exynos. What are your thoughts?
Mine comes from the Sprint S2, we were told it had the Exynos because of WiMax. The Exynos wasn't compatible with the LTE modem at the time so everyone else had the Snapdragon. Now, its due to energy issues and it sucking the battery because of, I can only assume, compatibility issues. Yet, the Note 3 has the Exynos and can use LTE, right?
So what gives? I don't care about which SoC is better - that would go on for months. Just the reason behind the choice.

T-Mobile note 3 has snapdragon 805 I think. Actually I think all variants do. I always read that snapdragons were actually better in performance standards and architecture of chip is why. Even though exynos may have a higher clock rate the snapdragons actually do calculations "better". Back when one of the galaxy series came out, I watched countless YouTube explanations explaining which is "better". As to why they use one in a us brand versus international version, no idea.

I don't think we'll ever know, honestly. For every article I point out showing why my reasoning is correct, there's another stating the complete opposite. I thought there was some plausibility to it being about money but my Exynos phone wasn't any more expensive than the Snapdragon version. Then there was the conspiracy theory about carriers controlling what SoC's go in phones, time travel, Kennedy. There might be a shred of truth in that story I'm just not sure where. Oh internet...
I liked my S2 but I have to say, the Snapdragon has always been a beast (you can OC the hell out of them too) and there's way more development support with them.

Someone once told me that Qualcomm has intellectual property rights to certain CDMA LTE modem technologies in the USA. This especially applies to CDMA phones for Sprint and Verizon. If that is true, then it is cheaper for Samsung to use Qualcomm LTE chips since using Exynos LTE chips would require a licensing agreement with Qualcomm.
Edit: I found this article that explains it: http://www.tmonews.com/2012/05/editorial-why-a-snapdragon-s4-galaxy-s-iii-is-awesome/
Excerpt:
"But if you are thinking that other carriers will get SoCs other than Qualcomm’s in the future, you’d probably be wrong. Most LTE modems do not support U.S. Digital Dividend frequencies, which means the LTE networks of AT&T, Verizon Wireless, and most regional carriers will be stuck with Qualcomm’s modems. T-Mobile can use non-Qualcomm LTE modems because the AWS band T-Mobile is using is a standardized band that is well-supported. Verizon Wireless, Sprint, and most regional carriers operate CDMA2000 networks, which means they have no choice but to use Qualcomm’s modems, since no one else makes CDMA2000 modems because Qualcomm owns all the IP rights to the cdmaOne/CDMA2000 technologies. Maybe once CDMA2000/LTE carriers start offering devices that don’t support CDMA2000, then we’ll see non-Qualcomm Snapdragon LTE devices on those networks, provided that U.S. Digital Dividend, ESMR+Cellular 850, and Extended U.S. PCS bands are all supported by non-Qualcomm modems by then."

Which LTE model use snapdragon

i bought this table Galaxy Tab S 10.5 LTE SM-T805 16G 2 days a go iam confuse becuase i read spcification of this tablet over the net all of them says WIFI SM-T800 and 3G SM-T801 use exynos 8 core and LTEs model use snap but my lte tablet use exynos
in general how many models can be found for this tablet ((TAB S 10.5))

As far as my understanding goes, all S models are Exynos for now.
Pro line is Snapdragon.

I think only certain US Carriers use the Snapdragon chip Tab S LTE.

this chipset exynos 5420 is 3g in general no 4g lte .this is new 5420 with lte included or lte has dedicated chipset ?
becuase my note 3 n900 exynos 5420 support only 3g freq. but 5420 in this tablet support 4g let
if use another chipset just for lte power consumption is too much more than 3g

as i know, the tab S model use intel chip to support 4g

I have not (yet) read on any Samsung site of any Tab S using Snapdragon. To avoid any future confusion, I suggest to forget the other sites, and go straight to the source themselves (Samsung) .....

I wish the moderators would fix this forum. It lists the Snapdragon 800 SoC in the tech spec details(above the individual forums)

Maybe they are oblivious to it and need to be informed. You could contact them and ask.

Gsmarena is one of these sites

The mods know about the Snapdragon issue. Because Snapdragon is offered in some limited markets they say it should remain. I don't agree as the vast majority of these devices are Exynos. It is misleading but they won't change it.

I could only suggest that they need to " amend " the description, not " omit ". Just add Exynos to it, that's all. Or go the " hard " way and have separate forums same as other devices .... End of confusion

I thought AT&T were getting the snapdragon LTE models. May be wrong though.

I wish there was a US model that had a snapdragon, I've been looking all over for one to no avail.

Samsung.com doesn't list any Qualcomm specs for the T700/T705/T800, says they're all Exynos™ 5 Octa (1.9Ghz Quadcore + 1.3 Ghz Quadcore).
The only possible Tab S with a Snapdragon is the T805.
Does anybody on this forum have a Snapdragon Tab S?

I just ordered the Sprint variant of the Tab S 10.5 (SPHT807TAB) yesterday, and it uses the Snapdragon 800 (MSM8974). Unsure if the other carriers have/will release it.

So the T807 is the Snapdragon model.
How's the performance?

It shipped out today, so I most likely won't know until Monday or Tuesday. But I'd imagine the performance will be just like my Note 3 since it's the same SoC and memory.

Yes, please keep us informed.
I picked up the WIFI version a few days ago after seeing it posted here that BB was discounting the 32GB. I am not noticing any significant lags other than within certain apps that I have also noticed it my Note 8. I would be torn over which to choose, the Snapdragon/Sprint or the 32GB version.
Incidentally, if you chose the the monthly option @ $27 (total $650) , did it also include the cellular plan for 2 years or was that additional? (Update:Never mind, found the answer on the Sprint website)

My Tab S from sprint will be here shortly. I will post back about its performance. I am trying to find out if there is a root method that works for this model.

So far, even with the crap-bloatware Samsung/Sprint like to pile on, and the memory-monster-TouchWiz; this tablet is performing quite well. The Snapdragon definitely makes up for all of the aforementioned annoyances. Certainly more responsive and 'snappy' than the Exynos variant that I've messed around with. I can't wait to see how fast this is going to be running once we have root and custom kernels.
I do find it odd that they went back to the old USB 2.0 port vs the duel 3.0 port though; I get great charge times with my Note 3 using that.

What's the SoC of N7105? Qualcomm or Exynos?

Hello, guys!
We want to buy another Note 2, and we found a good offer on the LTE variant.
Wikipedia reports that the "China 4G" model has a Qualcomm chip. Is it the N7105? We would like to know if it does mosty because we are interested in the Wolfson DAC, but a comprehensive list of the differences between the two models would be appreciated.

I recommended not getting any phone made for mainland China as these phones may have limited rom and play store support.
The non-China gt-n7105 has a Samsung processor per this: http://www.phonemore.com/samsung-galaxy-note-2-lte-gt-n7105-16gb/specs/1051

Mediatek devices don't support Non-Continguous carrier aggregation

Did anyone notice that all mediatek devices/chipsets even the recent G90T, G95, G85, or P-Series etc do not have
Intra-band Non-Contiguous CA (Carrier Aggregation) and
Inter-band Carrier Aggregation in them ?? except for the latest and recently launched Dimensity mediatek series. Most of their devices only have 1 type of Carrier Aggregation, even the latest phones launched with G80, G90T, G95; they only have simple intra-band Contiguous CA type implemented in them. I checked several phones and tested with different operators as well and only one type of Carrier Aggregation implementation is done by mediatek devices while snapdragon has better even on 600-series SOCs, etc.
Isn't this sort of silently being cheated by the mediatek ??. let us just take one SOC... as per mediatek G90T specs on its site it says 3xCA, 4x4 MIMO, 256QAM and speeds upto 1Gbps if you look up the pdf for same G90T series on their product page.
I searched a lot but still couldn't find any info or if anyone is getting other 2 Carrier Aggregation types working for them. But they have started offering all 3 types of CA after Dimensity 5G SOC series. I do understand that not all is offered as per the specs which involves other licensing stuff etc but still this is not right when compared to snapdragon devices. Its sort of like info related to which types of Carrier Aggregation is supported on devices is hid to users and user experiences speed issues related to 4G+ and its related and looking for means to unlock bands or CA types on Software levels which are sort of None for mediatek devices compared to Snapdragon when hardware itself is not support on mediatek.
Can you guys check if your mediatek devices older than dimensity supports Intraband Non-Continuous or inter-band CA ?. using any service mode/code or apps like Netmonster, etc. Do post screenshot if possible.
For those who are not aware or complaining Netmoster doesn't show proper CA info, Netmonster app just shows "LTE-A 2300" for Intraband Contiguous CA (Type 1 CA) along with 4G+ symbol on status bar for 40C;
"LTE-A 2300+2300" will be shown if a Intraband Non-Contiguous (Type 2 CA) is working on device. However this 2nd will not be shown monstly on mediatek devices on non-dimensity devices.

I maintain large database of supported Carrier Aggregation combinations cacombos.com. There you can check different devices combinations support.
Netmonster app is not accurate because it only show connected state and it doesn't always show right. Best way is collect modem log and read it to find supported Carrier Aggregation combinations.
There is also Helio -series modem support non-contiguous CA example: https://cacombos.com/device/CPH1951

Hi man, i am not highly technical person but i need help. I am using poco m4 pro 4G (g96) version which is 4G+ supported phone but it doesn't show 4g+ in status bar when mobile data turned on. While my 3 years old redmi note 8 pro showing 4g+ in exact same place exact same network sim card etc. I have tried messing with Apns and engineering mode settings but everything seems fine. i also checked in net monster app and poco is not combining bands while redmi note 8 is doing it so. i have tried installing other region roms as well but issue is still same.. Any idea what's going on?
