Wifi MIMO and LTE CAT 9? - OnePlus 3T Questions & Answers

Hi guys, i was wondering about the real differences fromo OP3. In OP3, they cut down the cost by not implementing all the antenna array form MIMO: https://forums.oneplus.net/threads/oneplus-3-cat-6-lte.450553/#post-15128371.
We have a fantastic Snapdragon 821, which has x12 modem, i think, so the question is: do they made the same mistake with OP3T? Does it come without MIMO and with an old x8 modem (only CAT6)? Is it again an hardware problem or can it be unlocked someways?
Thanks!

Unfortunately, this is not reliable. In the past, with OP3 they wrote it has x12 modem, mu-mimo etc etc, but then the modem was an x8 modem. So i wouldn't trust what they declare on the site much.

Yes i heard that one but here they clearly mention like:
"OnePlus 3T uses the integrated Snapdragon X12 LTE modem with advanced 802.11ac MU-MIMO Wi-Fi support." etc.
"The X12 LTE modem is designed to offer superior network coverage and 33 percent faster 4G+ LTE speeds than the previous generation modem, making sure that voice calls, video, and data get to the OnePlus 3T faster. "
Are they such a "liars"?

Yeah, the thing is they wrote almost the exact same thing for OP3:
"Blazing fast connectivity
Less time waiting means more time spent binging on Netflix. Thanks to the X12 LTE modem integrated into the Snapdragon 820, spotty internet is a problem of the past. The modem provides up to 33 percent faster 4G+ LTE speeds compared to the previous generation, so web pages and video streams load quickly and seamlessly. And with 802.11ac MU-MIMO support, the OnePlus 3 can download files faster with its 3X increase in user speeds and longer battery life, compared to traditional Wi-Fi."
And then we discovered Oneplus had cheaped out with the modem, not implementing all the antenna array. Qualcomm of course write down the technical spec of their modem, but who knows what Oneplus did with it..
I'm trying to get if they cheaped out again with OP3T, as it's marked as "CAT 6", even if the modem should go up to CAT 13.

Not cool then

There is no lie on that statement. Is talking about MU-MIMO not about MIMO.

Now the question is, is it possible to port Cat12/13 from other MSM8996. If it's hardware related like the USB port and FM radio it's futile. Vote with your wallet.

AT&T testing 7.2Mbps 3G, 14.4Mbps soon

Okay, I was browsing the internet, and i saw this article in the new testing of the 14.4 mbps and this is the article:
AT&T confirmed on Thursday that it has started testing some of it next-wave 3G services through a trial in Chicago. The upgrade follows previously revealed plans and gives users of supporting devices a theoretical peak 7.2Mbps download speed versus the 3.6Mbps of the current network. Upload speeds aren't mentioned but may not change depending on whether the service continues to use the older, download-focused HSDPA spec or the full HSPA format, which supports 2.9Mbps.
Carrier spokesman Mark Siegel doesn't say when the 7.2Mbps service will exit the trial period and when the network will receive the update, though the feature is believed tied to simpler software upgrades rather than a full hardware update. These speeds could also be increased to 14.4Mbps or more, Siegel adds.
Few AT&T devices directly support the faster 7.2Mbps standard and are primarily limited to devices like the HTC Touch Pro and the company's various PC modems. None currently support 14.4Mbps. A new Infineon chipset may give the 7.2Mbps speeds and faster uploads to the iPhone.
The official also reiterates that AT&T won't move directly from its regular 3G service directly to 4G on the Long Term Evolution format. Instead, the company still plans to first move to the intermediary HSPA+ standard. Siegel declines to say when this upgrade will take place or what speeds it will entail, though the company's wireless chief Ralph de la Vega has previously said download speeds would increase to around 20Mbps in 2009 through another software update for much of the network
SO, with this in mind, I might think that our Htc touch hd will be then running in a 3G band. that is my question to any one of you guys.

Speed test wifi and 4g vs iPhone 6S+

Just posting a quick result of a speed test on the might mix 256gb version. Vs the iPhone 6s+. Same network was used both in 4g and WiFi test on both devices, and the same Sim card as well.
The iPhone and mi mix performed equally good on WiFi. Both connected instantly. The Mix was a bit faster at loading uncached webpages.
On 4g it was a different story however. The Mix took on average about 30 seconds to connect to 4g (seems it favors H and H+) where as the iPhone almost had a 4g signal before I popped in the sum tray. There was also a noticeable speed difference of about 30% in favor of the iPhone, hitting a whopping 140-160mbps. The mix topped out at 90, but generally stayed at 70-80.
I live In a country with one of the strongest 4g connections in the world. It seems the iPhone is able to connect to 4g+ but the Mix isnt. What a shame. What are your network findings?
And the results from the iPhone 6s+ on the same network with the same Sim card

something odd
yes, the U.S (country that I live in) does not have the fastest LTE but even then no country has 140MBps (this is like the router speeds being touted for all kinds of MBps while the pipe into the home is nowhere near as fast; also depends on receiver h/w, if transferring files between computers versus communicating with outside world (internet))
maybe some aggregation going on?
I can see though the I6+/I6 connecting much faster as they have a much bigger band coverage and so tapping into whatever is available and connecting much faster .. that is true
(disclosure: do not own either of these devices..just trying to learn)

Looking to buy OP 3T; couple questions

Hello,
I'm planning to buy this device, but it's the Chinese model. I have found a good deal at 419 USD for that specific model. I have two questions:
1. The hardware difference in Chinese and European variants is ONLY in the modems, right? Otherwise I can treat the device as if it were the European model (i.e. flash OxygenOS and all the custom ROMs here), right?
2. The device supports all of my provider's 3G bands. However, when it comes to LTE, my provider uses two bands: B3 and B20. The Chinese variant supports the band 3, but not the band 20. Is this going to be a problem in getting LTE coverage and LTE data speeds? Cause I don't want to get a phone that won't work on LTE.
Thanks in advance.
1) Yes, aside from the radio, all hardware is the same. You can flash any ROM made for the OP3T on any model as far as I'm aware.
2) Having only half the supported LTE bands will definitely reduce coverage and may reduce speed. If your carrier uses Carrier Aggregation, missing one of the bands will result in your network speed being bottlenecked by the single channel. Different bands also have different ranges/coverage area and service providers may not necessarily broadcast at every wavelength at every signal tower due to hardware limitations.
The B2 band is on a longer wavelength compared to B20, so theoretically it is slower but has a greater range.

Thanks for the quick reply. So something like this won't work in my case?
I have personally never tried unlocking additional bands, though I'm going to assume there's quite a few risks associated with the process. If you want to try, consult this guide, which was made for the OnePlus 3 and is supposedly working for the 3T as well. Use at your own risk though.

Isthere difference between the snapdragon and exynos version in terms of connectivity

I have the dual sim exynos version.
Wifi is good but mobile network connectivity, whilst okay, isn't top of the line.
Looking at reviews online, they all seem to talk about the snapdragon version. I have no idea if those reviews applies to the exynos version.
When comparing my phone to my friend who has Oneplus 6. We get similar signals but he gets higher speed and latency is also lower. I hover around 60 mbps as maximum connection speed, he hovers well over 100 mbps.
The worst thing about this, is that when we're in oversubscribed area which is common, he gets through just fine. I cannot. Even if I put my phone on airplane mode then back to normal, I still can't get good connection.
We're on the same plan (EE UK, 4GEE max plan).

Question 4G Exynos Poor Performance

Hi
Tried comparing the S21 Exynos 4G performance against the S20+ or S10+? It's dissappointing...
I think most users are hitting their home or work WiFi and haven't yet noticed this issue with the S21 Exynos 4G.
If you have these phones and can do a comparison, I would be very interested to see if you duplicate the same poor 4G S21 problems: latency higher, download not as good and upload pathetic with the S21 Exynos series.
See my original thread here:
4G Performance on Exynos S21 Ultra is waaayyy slower than an S10+ or S20+
Hi Has anybody else noticed that the S21 Ultra doesn't seem to deliver consistent and reliable 4G speeds, particularly in terms of 4G uploading. I've done a comparison between my S21 Ultra and a S10+ both on the same network (EE) and the results are shocking. The S21 Ultra simply doesn't...

Thanks.
On my phone the 4g is better than my mate 20 pro and my oneplus 7t Mclaren... (all with same Telekom sim) but my 5g is bad... 4g is faster all the time (okay im in germany and think we have good 5g only in the vig cities and due to lockdown we cant test it)
Have the Updates made any improvements for you?
I don't know. Pretty good here.
No problems....

No improvement.
The problem is exaggerated when you have only an average signal strength. The modem is much more sensitive on the S21 and does not provide a good real world experience.
Same problem here. Any solution ? Thnx
I'm getting the same performance on the Ultra as I am on the Mate 20 pro...both on LTE and 4G.
Which means that the bottleneck in my case is the carrier.
Somewhat related : I ended up forcing band 12 with less bandwidth but better signal in my area..the phone stubbornly picks band 4 for almost double the bandwidth but 10-12dBm lower signal.
My battery is thanking me. The speed isn't everything.
I have the issue where i have very poor signal although my operator supposedly has very good signal in my area.
Ever since I bought the device in february my signal has been weak. I have aroumd 110-118dbm and speed of aroumd 50-70mb. My wife has an iPhone and same operator as I do and she gets 60-70dbm and at least double the speed. This is crazy, Come on samsung. This is ridicilous.
I hope an modem update will solve it but somehow it wont. We need to make samsung aware of this issue. My battery is kind of lacking because of this issue.
