Sent from my SM-N920V using XDA-Developers mobile app
Just came here to open a thread about this. What I don't get is all the news sources say that it's found only in the Snapdragon variant but if you look at Samsung's spec sheet for the global variant it also includes MIMO.
Look here under connectivity: http://www.samsung.com/global/galaxy/galaxy-note7/
Ah I see that my reddit post is reaching the larger audience! Check out the original post for a lot more info and ELI5: https://www.reddit.com/r/tmobile/comments/4wtsdy/galaxy_note_7_the_first_4x4_mimo_capable/
But I will also try to explain the benefits here.
- Up until now, all LTE smartphones had 2 Receive antennas in order to match the amount of Transmit antennas at the cell site, which sends up to two independent "spatial streams" in each transmission. In other words, when your signal is good, your phone is able to receive and demodulate both of those streams which provides faster download speeds.
- Over the past several years, T-Mobile begun equipping their LTE cell sites with 4 Transmit (and receive) antennas, which added additional diversity. Think of it as an additional set of "ears" at the cell site, able to "hear" your phone better since our phones transmit power is many times lower than Tx power at the cell site.
- Even though T-Mobile still sends out two spatial streams from the cell site, additional diversity allows operators to transmit data more efficiently, and essentially prepared operators like T-Mobile for the next step, 4x4 MIMO. This also helps with things like VoLTE, as the added antenna diversity improves overall signal resilience.
- In the meantime, there's been an ongoing struggle for OEMs to figure out how to implement 4 LTE Receive antennas in such a small smartphone form factor, and achieve acceptable antenna separation and isolation, and mitigate the interference. At the same time, in order to achieve the highest efficiency gain, signals that are coming into such a small device have to be uncorrelated, leveraging fading and multipath. I won't dive into that today.
- So adding 4 Receive antennas in the smartphone, just like T-Mobile has done at the cell sites, Samsung is effectively adding a set of "ears" and creating that same diversity on the user's end, which benefits not only users, but also operators as they're now delivering data more efficiently, especially to devices that happened to be in poor signal conditions.
- The best part happens when both the operator has 4 Transmit and the smartphone has the matching 4 Receive antennas. When that happens an operator can roll out 4x4 MIMO (Multiple Input Multiple Output) LTE feature, which effectively doubles download speeds, assuming good signal conditions, on top of improved resiliency when in sub-optimal signal conditions.
- So in T-Mobile's or Verizon's case, they typically have 20MHz Band 4 spectrum deployed for their LTE. In the existing 2x2 MIMO use case that yields up to 150Mbps peak downlink data rates, in good signal conditions.
But once they activate 4x4 MIMO, speeds double up to 300Mbps out of the same 20MHz Band spectrum, without operators deploying additional spectrum resources.
- Even in less the optimal signal conditions, in places where you'd see 5Mbps speeds, we should be able to see improved speeds because our phones now have more antennas and are able to maintain that connectivity with the cell site.
It's easy to see that we end up winning on multiple levels now that 4Rx antenna implementation in a smartphone became a reality. I plan on reviewing LTE Performance in Note 7 and other smartphones on my site http://cellularinsights.com so keep an eye on it if interested in this kind of tuff.
What does this mean for sprint users?
milan03, Snapdragon 820 LTE modem is known to support 4x4 MIMO and kudos for Samsung implementing 4 receive antennas in Note7 if it turns out to be true.
But what about the samsungs own integrated modem in Exynos 8890? I have not seen any specs about 4x4 Mimo support about it. International S7/S7 edge already include that modem. So has the existing samsung modem support for 4x4 or has has samsung upgraded their modem in Note7?

Is Rev. A capable of upgrading to Rev. B Through another radio update?
Forgive me if its such a simple question, I'm somewhat time constrained at the moment, and just wanted to ask.
Rev. B looks awfully cool. But it does seem it well require new hardware, as how Rev. B Works is somewhat different.
As quoted from QUALCOMM
"LAS VEGAS, April 7 /PRNewswire-FirstCall/ -- QUALCOMM Incorporated (Nasdaq: QCOM - News), a leading developer and innovator of Code Division Multiple Access (CDMA) and other advanced wireless technologies, today unveiled more of the Company's strategy for driving CDMA2000� 1xEV-DO Revision B to market. Still on schedule for commercialization in 2007, QUALCOMM's chipset solutions for the EVDO Rev. B standard will support unsurpassed wireless data rates to provide the springboard for delivering next-generation wireless data, music, gaming and multimedia entertainment devices.
"Consumers want devices that are smaller, lighter, faster, cheaper, as well as fully featured and with longer battery life," said Dr. Sanjay K. Jha, president of QUALCOMM CDMA Technologies. "We are committed to enabling our customers to meet these market demands, rapidly moving forward in the evolution of CDMA2000 technology to bring unprecedented levels of data throughput and network capacity with EV-DO Rev. B - capabilities that are necessary to support tomorrow's high-performance wireless applications."
Mobile Station Modem(TM) (MSM(TM)) solutions for EVDO Rev B will be highly integrated with advanced functionality, support the operation of up to three simultaneous channels of 1.25 MHz each for higher-speed data rates and deliver significant space-savings for devices that are thinner, smaller and lighter. The EVDO Rev. B standard supports up to 4.9 Mbps in each channel for a combined three-channel data speed of up to 14.7 Mbps on the downlink. With the processing power necessary for true multi-tasking capabilities that support the convergence of multiple consumer electronics features, and the ability to leverage the wireless bandwidth required to deliver these mobile services, QUALCOMM's chipsets for EV-DO Rev. B will deliver advanced functionality in a single compact, fully optimized device. QUALCOMM expects the first commercial EV-DO Rev B products to be data modems available in late 2007, with additional wireless devices available soon thereafter.
EV-DO Rev. B. technology is part of the Company's DO Multicarrier Multilink eXtensions (DMMX(TM)) platform, a set of technology and product innovations announced in November 2005. Enabling applications such as mobile TV or streaming music with a concurrent voice call, or conducting a Voice over Internet Protocol (VoIP) conversation while simultaneously browsing the Internet or transmitting multimedia content over the network, the flexibility of EV-DO Rev. B technology also enables significant network capacity and performance enhancements while leveraging existing network investments and currently deployed devices. Extremely high-performance devices could support forward-link data rates of up to 73.5 Mbps, while lower-cost or pre-existing devices could support 4.9 Mbps. Network operators may reduce their costs by allowing a greater percentage of spectrum to be allocated to IP-based services. The DMMX platform also includes numerous QUALCOMM-developed techniques to further enhance the voice and data performance of EVDO networks."
Very doubtful.
I also have a feeling that any of the handsets out on the market today wouldnt even be powerful enough, processor-wise to take advantage of the faster speeds. You might be able DL something pretty quick, but the phone probably wouldnt be able to keep up in terms of rendering on screen images or web pages.
From this:
Extremely high-performance devices could support forward-link data rates of up to 73.5 Mbps, while lower-cost or pre-existing devices could support 4.9 Mbps.

Are any carriers even planning on rolling out a Rev B network? Sprint is going WiMax, Verizon is going LTE. It may be a moot point.

Actually Sprint has formerly abandoned WiMax efforts with Clearwire. Too many problems getting certain aspects of the project working. Spirent which was the supplier of test equipment to Sprint and Nortel for testing WiMax had many issues getting there equipment working properly. I doubt WiMax will ever really take off in the way it was meant too. It is true that some WiMax deployment exists, but it's proprietary and sparse. Sprint is still considering WiMax networks but Rev B would probally be an easier route for them to accomplish as not much changes to the antennae
http://www.news.com/Can-WiMax-make-it-in-the-U.S./2100-1039_3-6217947.html?tag=topicIndex
You have to realize that Rev B (if it happens) is YEARS away from being implemented. I mean, Rev A isnt even fully out for Verizon yet in all markets, and only through hacks can pda phones even use it currently, otherwise its restricted to PC aircards.
All the existing phones out on the market today will long be obsolete by the time the next generation of internet speed (whether its Rev B or whatever it might end up being) is deployed.

Well this announcement is about a new chipset which would preclude you from just updating the radio.
and by the time the carriers implement REV B you will have had 3 new phones and more likely to have citywide WiFi if Google has it's way!
Hi.
I may possibly be moving about 30 mins away and the location has inconsistent signal...I get 4 bars of LTE in one spot, move literally 2 feet away and I am down to 1 bar of 3G signal. I need to have a very solid 4G-LTE signal as I use my phone for tethering as my main internet to my desktop and I also work a bit from home so this is important.
I am wondering if there is any product out there that can enhance my 4G-LTE signal on my phone that you can get and does not require a separate internet connection to work?
To my knowledge, the current Verizon network extender requires an internet connection and can only distribute/extend 3G speeds....this won't do.

Some may claim to extend LTE passively, but if you look at the specification, it's pretty much impossible to do passively. About the closest you can get is to build a picocell; a cell that covers a small home or office area. The reason they don't work is because LTE, like GSM, uses time division duplexing. This requires an advance in signal broadcast to compensate for the speed of light so that the handset's signal always reaches the tower inside it's assigned time window. The delay is a function of distance. Once your distance is greater than the allowable advance of the specification, the tower will drop your signal regardless of how strong it might be.

Judging by the fact they all have coax leads on them, they're specifically designed for permanent client installations such as home broadband or to build a small cell within or very near a home or building. Doing what you're wanting to do, as in creating a local cell that extends to where you're at and uplinking via LTE, is possible, but you'd have to clone a device that would authenticate on Verizon's network and I'm pretty sure that would be pretty illegal on a couple fronts.
Not sure where you live, but around where I'm at in the rural areas WiMax is a common broadband solution that provides pretty good data rates.

I know this is an old thread but just in case your still interested.
I have the Wilson Sleek LTE Booster. It took my Thunderbolt from Zero 3G to full 4G at my home. It was designed for mobile use but it works great. I know use it with an iPhone 5 with which it is even better. Wilson has a full home system that uses a directional outdoor antenna, and an indoor antenna that will connect an unlimited number of LT E devices all at once. I am getting this device soon.
I was traveling for work today and saw 5G signal. Wanted to see how fast it was, and was a bit surprised. Left me wondering what's so good about it?
Screenshots are of LTE and 5G speed tests.
Lower latency, faster speeds, better spectrum efficiency. It will get faster once the Sprint 5G is added in after the merger.

Interesting. Didn't see any of those benefits.
Benefits? Live faster, die younger. Like anyone asked for it
5G with T-Mobile is taking the opposite approach as Verizon/AT&T. Instead of trying to get INSANE speeds with very short range, they're building a network that has better than LTE speeds with much further range (higher frequencies=lower range, higher speeds, lower frequencies=lower speeds, higher range). Currently, it's not well-optimized since it's pretty new, but will improve within the next year.
Current 5G networks on T-Mobile are exclusive to 5G phones, making existing 5G networks so much less crowded. So while speeds may fluctuate, you're not having to share that network with anyone else basically, and you'll see better speeds in certain rural areas.
In Western VA, where coverage had been historically terrible, I was getting about 80mbs in places where my Pixel 3a XL was barely hitting 2mbs if I was lucky. It all depends on where you live right now.

I was getting over 100 in Saint Paul so not terrible.
Currently on the consumer side there are much more negatives than benefits. Higher power consumption, lower coverage, short ranges, higher cost. Otherwise on the consumer side, the benefits of 5G are much higher speeds (although this will drop drastically from the theoritical and current speeds once it gets wide adoption -- just as 4G) and lower latency.
5G is currently mainly still a push on the enterprise side. It allows them to direct the waves of the signal towards the users/devices and in turn provide a better connection. Another huge benefit is being able to connect much more devices at once. In a few years with smart home appliances, and self-driving cars with TVs in them they will be ready to sell you the streaming/bandwidth services you'll want for entertaiment in those devices.
If you never though "gee my 4G is pretty slow, I wish it was faster" (I personally never have), there is no need to get 5G.

What you're saying is not possible, research how the 5G technology works and you'll see what I mean. By nature, 5G has much higher bandwidth but much shorter range than 4G. Just the same as 5Ghz vs 2.4Ghz in routers. There is nothing T-Mobile or anyone else can do to change this, as it's the physics of the wave-lenght itself. 5G gets stopped by walls and other obstructions very easily.
What service providers are doing (and the only thing they can do with this techonology) is placing a boat-load of antennaes everywhere. And I mean tens if not hundreds times more antenaes than 4G (but much, much smaller ones). As such, it's not a strech to say that for 5G to be adopted outside of populated cities will take a while. Rural areas might never see 5G.
PS: Not sure what counts as "rural" areas in the USA. I assume most roads and especially big ones, even if the area is considered "rural" will be covered. By rural I mean small villages, woods, mountains etc.
The McLaren on T-Mobile uses low band 5G on the 600MHz band. Low spectrum means greater building penetration and long range (T-Mobile claims up to 2 mile range on low band). There's also extremely high band mmWave 5G, which the McLaren doesn't have. mmWave is the type that's super fast (like gigabit speeds) but has exceptionally short range.

Oh, I see. It does make a ton of sense to implement a lower spectrum in less densely populated areas. Nonetheless, the 2 mile range is still far off from 4G range capabilities.

It absolutely is possible. 5G doesn't simply operate on one wavelngth, rather, it refers to the tehcnology that's utlized to deliver more effecient bandwith. Like 4G LTE, there are different wavelenths with different speeds/distances. T-Mobile is running their 5G network on their 600MHz frequency currently which has much slower speeds than gigabit, but still decent ones that tend to perform about as well as a strong LTE signal. In fact, T-Mobile has been putting much focus on certain rural areas starting off, taking the opposite approach as AT&T and Verizon with their mmwave 5G.
My US model (XQBC62) is has having trouble with 5G on T-Mobile. 5G connects only intermittently in NSA mode.
Sony support says:
I'm asking you this because at this moment Verizon is currently the only U.S. carrier that supports 5G on the Xperia PRO model. The 5G network service is not currently available in the Xperia 1 III model and this is why you're getting that issue. In this particular case we recommend you to check with your phone carrier if there is a way for them either to provide a different network service or if there is a work around on their system for you to use your Xperia phone with their service
...
The Xperia 1 III phone does support 5G however at this moment the only phone carrier that provides 5G service on the Xperia phones in the USA is Verizon and at this moment they only support it on the Xperia Pro model. The phone carriers still working on providing the 5G service on all phone models they support and that depends on their coverage. I would like to give you a different solution however the phone service is covered by the phone's carrier and the best option you have is to contact T Mobile directly so they can further assist you with this issue
...
I would like to give you a different answer Kevin but at this moment the phone carriers don't support 5G service on the Xperia 1 III model and this function will be available through future updates by the phone carriers.
5G isn't all that great yet, maybe never.
More limited range and more obstacle intolerant than 4G. Average users see a 20% speed increase when in range.
Don't sweat it...
T-Mobile has 5G on the 600 MHz Band 71 so their 5G coverage is literally better than their LTE coverage where there's high signal attenuation (trees, mountains, stucco buildings).
It's disappointing to go from an LG Velvet 5G to an Xperia 1 III and start losing signal everywhere.
Does turning Airplane mode on/off get it to reacquire the 4G signal?
May be a firmware issue meaning the phone doesn't react to the signal conditions appropriately.
Maybe disabling 5G if it's possible would yield better results.
I just got a new 4G N10+ in part because of issues like this.

Like I said, coverage and performance is better if it can do SA 5G.
Releasing a NSA 5G phone was forgivable a year ago, but TODAY? It's probably sucking more power by constantly switching between LTE and LTE+NR constantly rather than just using NR all the time like other phones.

Excuse my 5G ignorance but...I use T-Mobile here in the US. I have 5G all day long if I want it. I rarely use it though because even though speed tests show that 5G is faster than LTE it also uses more battery. Also, there are times that while using 5G web pages load slower and YouTube videos buffer whereas when using LTE I have none of those issues. So while I agree that 5G is more gimmick than anything (for me) I still can connect to 5G without any issues at all so I am not sure what to think about the so-called Sony support answers????

There are two types of 5G.
Early phones had "non standalone" meaning that NR was only a temporary booster. The phone shows "5G" all the time but it's only momentarily connecting and disconnecting NR while keeping LTE on. These phones don't know how to use NR by itself or for phone calls. This sucks battery life and it causes stalls in data transfer.
Modern phones have "standalone" 5G. This means that the phone can use any mix of NR and LTE together all the time, including only NR. There's no switching and the phone can use whatever works best.
My T-Mo Velvet 5G got a huge performance boost in cell data when it received the SA update. Lag and dropouts around town were 100% gone . When walking around town, it's on LTE 2 + LTE 66 + NR 71. It can lose any two of those bands and be fine. It beats any LTE phone in stability. (RF absorbing stucco houses around here)
My new Sony has a MUCH faster CPU but it's a step back in cell performance. It's using LTE 2 or 66 (not both) and switching NR 71 on and off for data transfer. I frequently take it out of my pocket and see that it has no cell reception. Signal Check says it has NR 71 and is trying to connect to LTE.
I'm hoping a software update eventually fixes this. Much like the fingerprint reader crashes, this is a shameful launch for Sony.

My new Sony has a MUCH faster CPU but it's a step back in cell performance. It's using LTE 2 or 66 (not both) and switching NR 71 on and off for data transfer. I frequently take it out of my pocket and see that it has no cell reception. Signal Check says it has NR 71 and is trying to connect to LTE.
I'm hoping a software update eventually fixes this. Much like the fingerprint reader crashes, this is a shameful launch for Sony.

Well, assuming you know what you're talking about I appreciate your explanation of why I have stalls in data transfer and high battery use on 5G. Hopefully a software fix is possible and on Sony's radar. I have not experienced any fingerprint crashes nor have I heard anything about that. My fingerprint reader works great all the time. Anyway, thanks for the explanation!
Don't feel bad about "shameful" Sony launches.
Even Pixel's are dropping the ball as well as all the major brands. Too much, too fast...
Android 11 is the worst dropped ball of them all and that comes right from the top leaving the manufacturers with a mess they can't completely rectify. 2021 was a bad year for Androids. Google could have prevented much of this... Android, so secure it's unusable.
FWIW, the Pixel 6 seems to be swilling battery on 5G so most people are just disabling it. 5G was my original reservation on the 1 III, but now it seems less relevant so I'm considering returning my pixel and trying the sony.
Can anyone confirm that 5G radio can be shut down to save battery on the Sony? I'm pretty sure I'm reading that it can be, but want to be sure before I order. If it matters, I'll be on AT&T in the US.
Yes you can choose to NOT use 5G on this phone. I have turned it on/off several times and while speed tests show 5G as faster than LTE ... it uses more battery, and YouTube videos will buffer and web pages load more slowly??? Whereas on LTE none of those issues appear. So for now, at least on the 1 mark 3 - 5G is useless. Sad really but for me LTE runs everything just fine and fast!
Yes, well is any carrier on top of this?
Verizon's 5G rollout is going really... horrible.
T-mobile made this bold offer to boned AT&T and Verizon 5G users.
Anyone else contacted Sony about this? I posted a question here.
If this information is up-to-date, Sony disabled NR SA on all the bands used by T-Mobile.
Sony Xperia 1 III (US) (XQ-BC62) | 4G/5G Bands & Combos
4G & 5G Bands, Carrier Aggregation and Dual Connectivity Combinations for Sony Xperia 1 III (US) (XQ-BC62)
cacombos.com
This is weird because only T-Mobile has good NR SA coverage in the US.
I've tried to get customer service to forward this bug to engineering, but I don't think it happened (at least they provided no way for me to track it). And community support link I provided earlier just doing the typical finger pointing to blame the career.
I did a 5G comparison to a T-Mo LG Velvet 5G that does support SA 5G. The Velvet 5G has 10x the download performance but the Xperia 1 III has 10x the upload performance. When walking, the Velvet 5G produces a stable signal from carrier aggregation while the Xperial 1 III drops and reconnects frequently.
I would like to have a router that can be programmatically configured. Some of the associated features would include:
Monitoring data rates for each user and store such in selectable locations.
Read and record data rates.
Select specific towers and frequency bands.
Change APN and switch SIM cards.
The device could reside in a tesktop slot or USB connection.
Battery not required; if provided, not installing it should not disable operation.
No wireless network required.
GB Ethernet required.
If there are other considerations, I would like to hear more.
Thank you,
Ray
My needs don't correlate to yours, but maybe there is some ideas for you.
I have a desktop, RV systems, navigation that need a wired or WiFi or cellular connection.
I've tried hot spots but got fed up that they tend to stall/disconnect the wired/WiFi when they are scanning for a cellular signal.
So I got a cellular modem and a separate router with wired and WiFi.
My current modem is the 4G Netgear LM1200 which is selling for $150 or less now.
The router is some $30 thing which at least has better range than any hot spot.
I also like that I can keep some stuff wired, which I prefer when possible.
Most modems have all GUI based configuration.
The LM1200 has AT command stuff, but I haven't dived into it.
I'm more working on just getting better/quicker/easier reception/quality/band/tower info in JSON.
This may be interesting for you, but there is really nothing as of yet.
