I called AT&T today to ask about the HSUPA update. (Dial 611) And after being put on hold a few times, they said that they would have a manager call me back. Around 8:30, I got a voicemail (no call) from the manager, but when I returned her phone call, I spoke with a woman who offered me a $25 courtesy credit. I pressed her on the update and she swore up and down that it would be released in April, although she declined to give me that in writing. While AT&T has very little credibility with me, I wasn't too proud to accept $25. I recommend making the call.
I also called att and asked about hsupa update (so called 4g speed). Thought I was not offered any credit, i was told that there is going to be an update this month.
I also asked about unlock code, rep said, officially att will provice unlock code in dec 11

Hsupa does not mean 4g speeds! Do some research people....i cant wait till after the update for hsupa and everyone is complaining that they dont notice a difference in data speeds.

How would we not notice a difference in data speeds after HSUPA? The update will enable it on the phone. Speeds will increase. Period.
Care to explain?

I think he is referring to the fact that the update will simply increase upload speeds, while dl speed will remain unchanged, which does not have a huge impact on normal use...unless you are seeding torrents via your cell data plan I suppose.

Just wondering since I've never been to the states and I don't know about AT&T's history and policies.
Does that mean AT&T and Motorola has a kind of an agreement that unlock codes will not be given to users until a certain time passes? for exclusivity I mean.
I'm asking that because I wondered if the locked bootloader is also within the security package Motorola has provided to AT&T and maybe after that date Motorola can officially release the code.

This is by no means a defense of AT&T's rather liberal definition of "4G," but if you want some research, this is what I came across while I was on hold. So if you're interested in having more than vague internet rumors to support your claims that AT&T isn't living up to its end of the bargin, here you go:
4G has no official definition.
ITU on 4G: http://www.itu.int/net/pressoffice/press_releases/2010/48.aspx
4G Americas on HSPA:
http://www.4gamericas.org/index.cfm?fuseaction=page§ionid=247
I think the above link is actually quite damning of AT&T's actions with respect to disabling HSUPA on the Atrix. The group defines an HSPA network as one that is using both HSDPA and HSUPA (aka E-DCH) simultaneously. While 4G Americas is not a standards organization, they are a powerful telecom industry lobbying organization of which AT&T is an influential member. (see http://www.4gamericas.org/index.cfm?fuseaction=page§ionid=160)
3GPP on HSPA+:
http://www.3gpp.org/HSPA
While HSPA+ is mentioned on the above linked 3GPP webpage, there is little mention of HSPA+ by name in the technological specifications --the specifications deal mostly with the constituent technologies that make up HSPA+. When HSPA+ is mentioned, from what I've read, it's mentioned as Evolved HSPA or something similar. HSDPA is frequently mentioned as it has been in the pipleline since Release 5, and HSUPA is only mentioned by this moniker in a few places --it is most commonly referred to as E-DCH or Enhanced Uplink.
I would love to see an official 3GPP release that explicitly says "For a network to qualify as an HSPA+ network, ..." but I haven't found something that helpful. The standard is a bit of a disaster because: (1) it's HUGE with over a decade of revisions, and (2) a large number of standards have been withdrawn. Many technical specifications that have not been withdrawn will mention a technology that is not being defined and reference a withdrawn specification. I'm not sure what that means for the non-withdrawn specifications.
Here are a few interesting things that I was able to pull up from the 3GPP site. Unfortunately, the specifications use a lot of "shoulds" and "mays."
From 3GPP TR 25.999 version 7.1.0 Release 7 (HSPA evolution Technical Report) "Evolved HSPA should be able to operate as a packet-only network based on utilization of the high speed data channels only (HS-DSCH, E-DCH and associated channels)."
If this is stating that an HSPA+ network must use HSUPA and HSDPA, clearly AT&T fails. Even though HSUPA is running concurrently on the network, as Atrix users can't use it, claiming the network satisfies the HSUPA requirement would be a little like your cable company claiming they provide you HBO because your neighbor has it.
Again, from the same document: "Evolved HSPA protocol architecture shall have minimum impact on [user equipment] especially in terms of complexity, to allow for easy introduction."
I think a compelling argument can be made that the loss of HSUPA functionality on the Atrix has caused problems with the Atrix working on foreign data networks. The Atrix should be able to operate on foreign HSPA+networks that are frequency-compatible, but the burden of proof is on AT&T to show that their modifications don't interfere with basic usage of the Atrix on other HSPA+ networks.
From 3GPP TS 25.319 version 7.8.0 Release 7 (Enhanced Uplink Technical Report) "The Enhanced Uplink feature shall enable to achieve[sic] significant improvements in overall system performance when operated together with HSDPA. Emphasis shall be given on the potential impact the new feature may have on the downlink capacity."
By forcing the uplink to travel on a separate network, not only has AT&T demolished the uplink speeds, downlink performance has suffered, too. I've seen speculation that the latency issues can, in part, be attributed to the fact that the uplink and downlink packets are out of sync, causing a lot of unnecessary data retransmission; although, I can't cite anything definitive to prove this.
From 25.999 "[The UTRAN architecture] should reduce user plane latency to legacy (R5,6 & 7) & beyond R7 terminals" and "reduce control plane latency to beyond R7 terminals and, if low complexity cost effective means can be
found, also to legacy terminals."
While only considering latency in one direction, on one fragment of the network, AT&T may have met these requirements, but in aggregate, latency has jumped by an order of magnitude. In 25.999, there is a table of target ping latencies, with HSPA+ being listed at <50ms. AT&T's solution is nowhere near that level of performance.
There is a lot of information in 25.999 regarding the deployment of an HSPA+ network into an existing HSPA network, but without details of how AT&T has structured their upgrade, there is little one can glean from this. Although, it is clear that HSPA networks are considered as separate entities from HSPA+ networks. For example, from 25.999:
"The potential HSPA Architecture evolution will be defined independently from enhancements in the HSPA radio interface (both layer 1 and radio protocols). Thus, the traditional UTRAN interfaces (Iu, Iur and Iub) shall be enhanced in order to support the features included in the evolved HSPA radio interface. However this does not preclude the possibility to introduce new features in the HSPA radio interface, in case they are beneficial mainly to one of the
architectures."
Here they are specifying that the HSPA standard will be updated so that the interfaces (Iu, Iub, Iur) between the various sections of the network can be shared by HSPA and HSPA+ networks. But its clear that HSPA networks are distinct from HSPA+ networks.

You have to submit your email address to download the documents, but it is very easy.

I got 25 Bucks credit too!!!
Jeez some people are so hard up for $25 that they'd jump through hoops on the phone with AT&T?
BTW I notice HSUPA when I take a photo and e-mail it, which I do fairly often. With ~2mbps upload it is about 10 seconds per pic, with 5x slower speed well you wouldn't want to be sending more than one at almost a minute each.

im sure google has been talking with tmobile and htc about 4g, whether it be wimax or LTE. can anyone confirm if it supports either? not only would that make the phone more awesome, but we could be more certain on tmobile 4g plans. i mean sprint already has it on the pre, and google gave the n1 specs to beat out most opponents (asside from the hd2, but i dont think that supports 4g either :/ never looked).
any idea or confirmations would be welcome
damn. oh well, the 3g boost is good enough for now
What a bollocks question. Networks won't be that mature for AT LEAST 18months.
LOL. i didnt think it would, but it wouldnt surprise me if google did have htc put it in
Knowing HTC they will stop supporting this phone in 6 months. £100 says the Nexus 2 will be out by Christmas.

T-Mobile has no intentions, as of right now, of going to 4G. Its simply not needed. Explanation: Sprint and Verizon are CDMA technologies. CDMA (Code Devision Multipable Access) has a 2.5MHz bandwidth. With that they use EVDO for thier 3G data rates but because of the bandwidth of CDMA they are very limited on their max download speeds. With that said, both carriers will have to go to 4G, WiMAX or LTE, in order to achive high data rates.
On to T-Mobile: T-Mobile has recently installed a UMTS 3G network which uses WCDMA (Wideband Code Division Multiple Access). WCDMA has a 5Mhz bandwidth which, by easy math, is double the capability of Verizon and Sprint. UMTS uses a technology called HSPA+ for its data. HSPA+ is capable of download speeds up to 48Mbps. As of right now, T-Mobile is making efforts to seriously increase their data speeds using HSPA+ and as of right now T-Mobile has HSPA+ launched in Philidalphia and is getting great reviews.
So, with all of that said, hold on because by the end of this year T-Mobile will probably have the fastest network.
Why 4g on a phone, if 3.5G 7.2Mbps worked fully, its more than enough, for youtube, iplayer and daytoday surfing.
22Mbps from mobile, networks - its a joke max speed will be about 4-6Mbps if one is lucky and much less in most areas

So when all this happens according to planned, and hoping it will. Will current phones now(Nexus One) be able to benefit to the new speeds?
not necessarily all current phones, but the nexus one does... when you take a look at the specs, there is HSDPA and HSUPA... the more common nomenclature would be HSPA+ and HSPA as some people like to put it...
with the upgraded network speeds that t-mobile announced as of the fifth, my average download speed has jumped from 600kbps max to 1 mbps on my nexus one... a pretty hefty improvement, and its only gonna get better... don't really see the need to upgrade to anything faster at the moment because most cell companies can't handle the load of data thats going across their networks as is... they upgrade speed, they have to upgrade capacity too and that means more hardware, its not as simple as swapping to HSPA+

HSPA (High Speed Packet Access) and HSPA+ (Evolved High Speed Packet Access) are actually 2 different things. HSPA is capable of up to 14Mbps down while HSPA+ is capable of up to 54Mbps down. T-Mobile is currently running HSPA nation wide and running HSPA+ in Philidalphia. T-Mobile hopes to be running HSPA+ nation wide. HSDPA and HSUPA are simply HSPA with the D for Download or U for Upload added to the acronym to differntiate the different up and down speeds.

On a mobile device, where there are other factors involved, such as cpu and other performance components.
My phone speedtest gets 15Mb on wifi and about 3.5Mb on 3G but the real life speed when using the internet seems much slower even with wifi because the device can't handle or process the web pages as fast as a PC, also i doubt people will use rapidshare on the phone where speed matters,
For genral surfing a good 1MB connection is enough for mobile devices, i think anyway.
I use usb modems by huawei i have many most have 7.2Mbs with vodafone i get 3-5Mbps but still seems very slow, mostly due to the ping which are normally in the 300ms+
ADSL/DSL is best for speed, mobile BB even at 50Mbps will not compare to 20Mbps DSL line. As DSL is much more stable and Mobile BB is NOT very stable

Now if they could just get 3g in my area this year.....
Personally, I'm not happy that Sprint has decided to go with WiMax. On one hand, we've always been kind of blocked from using imported phones... but on the other hand, Sprint wasn't the only CDMA carrier in America, and there were enough other companies using CDMA elsewhere in the world to ensure that we got to have phones that were at least as cool (often, better) than what Europeans could buy for GSM (especially with regard to the first PalmOS PDA phones, and generally with regard to Windows Mobile PDA phones).
As far as I can tell, Sprint is the only carrier on *earth* going with WiMax instead of LTE. It's one thing to be limited to the same phones used by Verizon, just about everyone in South Korea, plus half of Australia, South America, and a big part of China. It's another matter *entirely* to be the only 20-40 million people on Earth stuck with phones that literally have no market anyplace besides Sprint in the US.
I remember going to an AT&T Wireless store with a coworker in 2004, right before they switched to GSM. I looked around the store, and couldn't *believe* anyone wouldn't take one look at the 20th-century relics they were still selling to new customers and run from the store screaming. That's what being REALLY "ghetto-ized" means.
We won't even be able to ***** about Sprint not supporting R-UIM cards, because there won't be any non-Sprint phones that are even capable of working on Sprint.
I've been a Sprint user since ~1999, and it really hurts to think I might eventually be forced to choose between leaving Sprint or settling for a second-rate phone that sucks as badly as AT&T's TDMA phones did relative to the phones Sprint, Verizon, and even T-Mobile had at the same time.
The biggest selling point I've seen for WiMax so far is the fantasies some people have that it will replace WiFi... totally overlooking the fact that people don't use WiFi because it's the best... they use it because it's free. It uses internet connectivity that someone's already paying for, and enables its use in more ways. It's the same reason "3G tablets" are going to flop (in the short term, at least) in America, unless they can ALSO use WiFi and tether to cell phones. Very, very few people are going to willingly throw down $500 for a new device that requires yet another new $10-40/month fee to use it unless it's literally god's gift to the computing universe. AFAIK, nothing remotely close to being *that* cool is hitting the market anytime soon.

Bet $200 that it'll be out by June.
Many of us are so geeked about 4G speeds....the mytouch 4G sprouting about its HSPA+ network which is supposed to make this a better phone and such, but it's all hogwash. I found the article below very interesting and rather revealing as to how these carriers manage to soup us up and get us to believe what they want us to believe, true or not. Sad, but very enlightening.
NEW YORK (CNNMoney.com) -- You've seen the 4G advertisements from T-Mobile, Sprint and Verizon, bragging about a much-better wireless network with blazing fast speeds.
Here's the secret the carriers don't advertise: 4G is a myth. Like the unicorn, it hasn't been spotted anywhere in the wild just yet -- and won't be any time in the near future.
The International Telecommunication Union, the global wireless standards-setting organization, determined last month that 4G is defined as a network capable of download speeds of 100 megabits per second (Mbps). That's fast enough to download an average high-definition movie in about three minutes.
None of the new networks the carriers are rolling out meet that standard.
Sprint (S, Fortune 500) was the first to launch a network called 4G, going live with it earlier this year. Then, T-Mobile launched its 4G network, claiming to be "America's largest 4G network." Verizon (VZ, Fortune 500) plans to launch its 4G network by the end of the year, which it claims will be the nation's largest and the fastest. AT&T (T, Fortune 500) is expected to unveil its 4G network next year.
Those networks have theoretical speeds of a fifth to a half that of the official 4G standard. The actual speeds the carriers say they'll achieve are just a tenth of "real" 4G.
So why are the carriers calling these networks 4G?
It's mostly a matter of PR, industry experts say. Explaining what the wireless carriers' new networks should be called, and what they'll be capable of, is a confusing mess.
To illustrate: Sprint bought a majority stake in Clearwire (CLWR), which uses a new network technology called WiMAX that's capable of speeds ranging from 3 Mbps to 10 Mbps. That's a different technology from Verizon's new network, based on a standard called Long Term Evolution (LTE), which will average 5 Mbps to 12 Mbps.
Seeing what its competitors were up to, T-Mobile opted to increase the speed capabilities of its existing 3G-HSPA+ network instead of pursuing a new technology. Its expanded network -- now called 4G -- will reach speeds of 5 Mbps to 12 Mbps.
No matter what they're called, all of these upgrades are clear improvements -- and the carriers shelled out billions to make them. Current "3G" networks offer actual speeds that range from between 500 kilobits per second to 1.5 Mbps.
So Sprint and Verizon have new, faster networks that are still technically not 4G, while T-Mobile has an old, though still faster network that is actually based on 3G technology.
Confused yet? That's why they all just opted to call themselves "4G."
The carriers get defensive about the topic.
"It's very misleading to make a decision about what's 4G based on speed alone," said Stephanie Vinge-Walsh, spokeswoman for Sprint Nextel. "It is a challenge we face in an extremely competitive industry."
T-Mobile did not respond to a request for comment.
One network representative, who asked not to be identified, claimed that ITU's 4G line-in-the-sand is being misconstrued. The organization previously approved the use of the term "4G" for Sprint's WiMAX and Verizon's LTE networks, he said -- though not for T-Mobile's HSPA+ network.
ITU's PR department ignored that approval in its recent statement about how future wireless technologies would be measured, the representative said. ITU representatives were not immediately available for comment.
"I'm not getting into a technical debate," said Jeffrey Nelson, spokesman for Verizon Wireless. "Consumers will quickly realize that there's really a difference between the capabilities of various wireless data networks. All '4G' is not the same."
And that's what's so difficult. The term 4G has become meaningless and confusing as hell for wireless customers.
For instance, T-Mobile's 4G network, which is technically 3G, will have speeds that are at least equal to -- and possibly faster -- than Verizon's 4G-LTE network at launch. At the same time, AT&T's 3G network, which is also being scaled up like T-Mobile's, is not being labeled "4G."
That's why some industry experts predict that the term "4G" will soon vanish.
"The labeling of wireless broadband based on technical jargon is likely to fade away in 2011," said Dan Hays, partner at industry consultancy PRTM. "That will be good news for the consumer. Comparing carriers based on their network coverage and speed will give them more facts to make more informed decisions."
Hays expects that independent researchers -- or the Federal Communications Commission -- will step in next year to perform speed and coverage tests.
Meanwhile, don't expect anyone to hold the carriers' feet to the fire.
"Historically, ITU's classification system has not held a great degree of water and has not been used to enforce branding," Hays said. "Everyone started off declaring themselves to be 4G long before the official decision on labeling was made. The ITU was three to four years too late to make an meaningful impact on the industry's use of the term."
I understand all that. But here is my newbie question:
Can the 4G TMo devices (say myTouch4G or G2) really attain quicker d/l speeds than a 3G device like Vibrant? If so, how?
I have not been able to read a clear explanation of this anywhere. Also, TMo says their network will hit 21Mbps in 2011, and that is backward compatible. If so, then why is a 4G device needed?
Call it 10G if they like its just a name, I dont care as long as the speed meets my need at a reasonable price.
because our phones are only capable 7 mbps while the g2 and the mytouch4g can go to about 14 mbps (not even 21) ... but yeah thats why ... its hardware related

They are backward compatible, for example HSPA+ will give vibrant which does not support HSPA+ a speed boost, just not fully benfitted. Same story with USB 3.0 and 2.0
4G is 100 mbps and TMobile will be 21mbps. None of these networks will have 4G speeds and all in fact are upgraded 3G speeds. AT&T will be usding the same HSPA that TMobile will be using and eventually they also will be at 21 mbps.
How any of these carriers can call themselves 4G is beyond me.
Actually the 4G spec calls for 1 Gbps stationary speed, the 100 mbps is the minimum while mobile so it will be 5 years before you really see that.
T-mobiles current "4G" Network is currently running at 21 mbps, with 42 mbps a software upgrade away. So while they don't meet the true 4G speed threshold, neither does sprints current 10 mbps wimax, or verizons 12 mbps LTE. When sprint and verizon first launched their "3G" networks they didn't meet the requirements for at least a couple years, and we are not any worse off due to that flexibility.
I still roll with a 7.2 mbps vibrant and I will be honest, there has not been any time where I had good 3G speed that I needed anything more.

think back to USB 2.0
when USB 2.0 came out it allows for higher speed transfers etc....
You will only get 2.0 speeds on a 2.0 port.
The USB 2.0 device will work in a 1.0/1.1 port, but it will not give you 2.0 speeds.
if you want, just replace USB 2.0 with HSPA+
and replace 1.0/1.1 with HSPA7.2
Let me try to shed some light on things for you.

Yes. Without getting all technical, it has to do with how the data is compressed and encoded on the different channels that the phone and cell towers use.
HSPA+ is an improved version of HSPA. HSPA is an addition to UMTS 3G which allows for faster data transfer rates than just regular UMTS 3G.

You won't find one unless you do some real digging and learn enough to understand some basics of UMTS. True 4G does a lot more than just give faster data rates. The entire back-end of how the cell towers and core network route information is different. The way the radios in the cell phones work is different and the way the cell towers organize data is different. The benefit is more efficient mobile communication service.
The way things are with 3G, it is difficult to balance voice traffic with the ever-increasing demand for data traffic and maintain QoS for a large number of users simultaneously. Anyone who has tried to use AT&T 3G at a football game or concert can tell you how crappy the service gets when the towers get loaded.
Yes But Marketing.......
All that tarzanman said is correct but the larger picture is just perception and controlling it.
Basically, we really do not have 3g unless you really get somewhere close to 7mg speed consistently........We do not and i am ok with my 2-3mg speed it is plenty good enough for my needs.
Here is a good analogy......when front wheel drive car first came on the market they were hailed as a breakthrough in making a car handle better allowing more room in the car and being safer. The fact is only a little more room is the real benefit and the rest....well, it is just cheaper and easier to mass produce. The car handles poorer than a rear wheel car or 4-wheel. But, they convinced most of the dopey-ignorant customers/masses and even to this day people still think they are better. Moral of the story.........control the message and control the spin, and to hell with facts........ because most don't care they just want the latest "craze jargon" on their lips so they feel cool...(sorry for the rant)
I have had a cell phone now for 27 years.......and here is my advice:
here in the USA --go with T mobile for now watch the business trends and when they start acting like Verizon and Att then look for the next up and coming carrier and then go with them.. That is the only way to have decent, reliable and fast connection speeds for a reasonable prices.
Who cares? As started in the article ITU's decisions hold no water. They have no authority and their definition is arbitrary. I'm in the product development industry, and when our end product goes through a redesign or significant optimization it gets a generation bump. We're now up to third generation. Product looks the same for the most part, but performance increased as a result of engineering changes.
For the wireless industry, all carriers are implementing significant performance increases through network upgrades. These upgrades are not 100% compatible with current generation devices. As far as I'm concerned that's worthy of a generation bump. People are splitting hairs for no reason. It's quite silly. If I were an engineer for any of the major carriers right now I would be pretty annoyed with this ITU business by now.

It is easy,
HSDPA+ (TMO), EV-DO(Verizon), LTE(Verizon) and 802.16e Wimax(Sprint) are considered 3G Transitional.
LTE Advanced and 802.16m (WiMax "Advanced" if you want to call it that) are 4G.

Verizon can call their LTE whatever they want but the fact is it isnt as fast as TMobiles HSPA+
i rather have true unlimited 3G than some bologni 4G with a 5Gb cap. May be is too much to ask for.
Remember, Most tout 4G more or less as 4th Generation rather than true 4G. Although marketing says otherwise. It's a ploy to get your service, just like spray painting your head makes you look like you have more hair. I don't care what they call it, as long as it benefits my speeds.
For companies that have actual caps. its stupid that they are increasing the speeds that you hit your cap. So you may have better speeds to do more, but really you are just hitting your cap faster so you can pay them more money.

indeed it is. And unless you want to read a few 700 page books on the differences between UMTS/WCDMA/HSPA, and LTE/LTE-a, that's about as good of a source as is available at this point.
And as to the OP - it's all about marketing. Technically speaking, 1xRTT and EDGE are both 3g technologies. But cell companies hyped up EvDO and UMTS as 3g, to simplify it for the American consumer.
And so they're marketing their next generation of networks as "4g", even though that doesn't meet up with what the ITU defines as 4G on technical terms.
Again, this is all because cell phone companies know that people buy into the hype rather than concern themselves with the details.
But in the end, who gives a damn? It's significantly faster than what people used to expect from 3g (ie 1-2mbps), so as long as the results are better, they can call it 9000G for all I care.
All of this 4G related discourse is exactly what the carriers want. Four gee shmoor gee. I'm just happy I get 3-5 mbps down where I live.
In the end, we are all just stupid pawns

My email to her is below. But here is her response. So just hold it out people. It is coming. The phone supports it. AT&T just needs to "Turn it on"
Hi Donnie,
This means that the 4g Atrix is going to be ABLE to use the 4G service once it is available however, we do not have the service alive yet therefore you will not get those speeds at this time. We are proactively working on getting the network upgraded. Houston is a HOT spot for this project so I know it will not be long.
Thank you,

Email i sent to my at&t rep who handles my corp account of about 150 phones.
According to ATT Website the Atrix, supports “4G” By using HSPA+. Houston is a HSPA+ market, but we have been unable to HSPA+ service.
We contacted CS and they said it was prolly a down tower. But I do a lot of driving and know that one tower would not affect all of Houston. So we hit up Google, and the results are disturbing. Motorola says it does not support HSPA+. Yet att website says it does. Many sites say that AT&T has disabled it. We need to know the truth. We bought this phone because it is listed as a 4G phone, but it seems we were misled. If you would please research this and shed some light on the matter.

More BS from AT&T.
HSUPA is DISABLED on this device and i don't care how many lies at&t will try to push to cover this up.
Hey Donnie,
Had pretty much the same question for my Rep yesterday. Let me go ahead and say that I've yet to go to a market that is HSPA+ with my Atrix; my rep doesn't have one yet, she has an Inspire. She has been in "4G" market coverage where her phone shows 4+, the indication for 4G, and it's faster than her IP3 but not 2x as fast as 4G is supposed to be.
She told me that some markets are "4G" but only in the sense that they are running at 3.1 Mbps, which according to the FCC qualifies, hence At&t saying they have no 4G coverage. 4G being 7.2 Mbps.
She also informed me that At&t is not pushing 4G upgrades so much as they are pushing LTE upgrades, which according to her can run 5x as fast as 4G?
Sorry for the rambling, but I thought you might like that information.

But you can believe whatever you want if it makes you feel better.
I know we're not getting HSPA+ speeds, but there's something even more. I have yet to see someone get more than 400Kbps UPLINK.
This is not just on AT&T.

Odd how my Captivate has HSUPA speeds yet my brother's Atrix doesn't... So much for the speeds not being available...

HSPA+ *IS NOT* HSUPA. They're separate services. When AT&T enables HSPA+ across the country they'll also most likely send out a patch to enable HSUPA on the devices. Settle down on the conspiracy theories.
HSPA+ isn't enabled because the system isn't finished. We *all* knew this. When it is (in the next month or 2, most likely) they'll enable it and you'll see the difference overnight. My dad's worked for AT&T for 42 years as a repair tech (one of the 2 in this state that upgrade a majority of the HSPA+ and LTE hardware) and said the rough estimate looks like late March or very early April for HSPA+ and LTE in fall.

that is great speeds... im in an area where there is no H+ yet, in greensbroo NC but Charlotte NC has it and we a re the next to get it in NC... and i am getting 3.8 but without the HUSPA, we are getting .3/.4 uploads... no matter how fast our DL's are without an upload to match it... those speeds are kinda pointless
"HSPA+ *IS NOT* HSUPA. ...
HSPA+ isn't enabled because"
Well, my phone shows "H+" up top, indicating it is enabled in this area. But AT&T has some clever ideas about hardware deployment. When I called to ask about some problems last year the rep said "Oh, I see there are a number of degraded towers in your area, that could be the problem." "Is there anything else I can help you with today?"
I said "Yes, can you give me Verizon's number? I'd like to ask them how there towers are." <WEG>
Hey, I know one's no better than the other in the big picture. But lord, does the FTC need to make the cellcos ALL COME CLEAN and stop the lies.
Apparently the H+ doesn't necessarily signify HSPA+. Covers 3G and their "4G".
"Question:
What is this "H+" icon on my phone's screen?
Answer:
The "H+" icon is a network indicator. When present, it lets you know that your phone is operating on our 3G or 4G network (where available). "
"Question:
How will I know if I'm on the 4G network vs. your 3G network? Is there any visual indicator on the phone's screen itself?
Answer:
While there is no visual indicator on the phone's screen that differentiates the difference between 3G and 4G data speeds, when experiencing 4G speeds your videos and streaming movies will download/play even faster, web sites will load even faster, and large files will download faster. "
"Question:
Will that "H+" icon ever change to something else? If so, what other icons might I expect to see and what do they mean?
Answer:
The H+ icon will remain lit while connected to either our 3G mobile broadband or 4G network (where available). Should you travel outside of those coverage areas and/or experience extreme network congestion, the icon may display EDGE or E while on our 2G data network or, in some instances, it will display GSM. "
Att rep for our company confirmed that they are working together with verizon to "pull the trigger" on 4g running at full throttle within the next couple of weeks. He showed me some emails and charts showing that they have installed verizon's hardware in their towers and are debugging it now. I did not see that "partnership" coming at all to be honest lol Keeping fingers crossed ))

I noticed this up here after doing this MOD. Before the mod the notification bar only showed H+ all of the time. Now it bounced between 3G and H (not sure about H+). I am assuming the display I am getting now is correct.

Okay that makes sense but why is it though that other devices like my unlocked streak or nexus one get much higher upload speeds than the atrix? Is it something in their rom that is allowing them to get good upload and the atrix rom not allowing it to? Trying to make sense of it all.
Dell Streak powered by Streakdroid 1.8.1
Video with proof
It's obvious to everyone now, but I made a video that can easily be shown to anyone who doesn't believe the ATRIX has slower speeds than something like the iPhone.
Show this to AT&T and then they'll shut their mouth about "possibly a defective device."
www[dot]youtube[dot]com/watch?v=X5YMJT08N64&hd=1
I'm sick of this bs. Why cant this company live up to their promises?
the atrix isn't even an HSPA+ device, it has an HSDPA cat 10 modem...
The Atrix is supposed to have the HSPA+ transceiver in it. Whether it is disabled or does not work because the network blocks access since HSPA+ is not fully deployed is a question heavily discussed in other threads in these forums. However, you should realize the LTE requires a different transceiver, which reviews have indicated the Atrix does not have.
So even if LTE is deployed this fall, the best the Atrix will be able to do is HSPA+, not LTE. Supposedly, LTE-capable smartphones are supposed to be announced this summer sometime.
Wanna wait?

Ha!

I'm in New York City....
--Q
Bell has done the same, retroactively labelled all of their 14.4 phones as 4G.
I think they should have gone, at very least, with 21 which is release 7 HSPA+ and has 64-QAM.
Of course ideally they would've have stuck it out with '3.5G' which is what these are, just evolved 3G with faster speeds, and kept 4G for LTE which has other tangible benefits mainly lower latency. Who cares how many megabits you can pump when the latency of 50+ ms bottlenecks most tasks.
Completely agreed! Doesn't engender a sense of confidence in your wireless provider.....a buncha liars and PR-twisters....disgusting really....
The update indeed makes the phone able to get such high speeds, since the modem was capped. BUT that doesn't mean att will server that speed to you.
That's a ceiling value, not an average!

Atrix upload is still capped, just higher than before
god, i've never been this annoyed at AT&T in all my 10 years of being with them. seriously they are such marketing whores.
What 4G was supposed to be, IMT-Advanced is. Wireless carriers marketed 4G as whatever they wanted while it was not a frozen standard. By the time the ITU actually laid out a concrete plan, it was too late. The wireless carriers confused the market completely with their bull****.
IMT-Advanced will have IEEE 802.16m (the new Mobile WiMAX Release 2 or WirelessMAN-Advanced) and LTE Advanced. These are currently the only 2 IMT-Advanced complaint plans. This is what 4G was supposed to be.
IMT-Advanced is still some time away from what we currently have, and NO carrier is implementing this technology in production environments yet. It's not just AT&T, it's every carrier that says they have 4G and every mobile vendor who says their phones at 4G. They're not.

Sent from my Motorola Olympus
In my opinion - T-mobile's faux 4g (HSPA+) is better (and I suppose AT&T has it as well, but AT&T sucks ) than LTE 4G, but I would like to know what you all think?
This thread is for the amiable placement of our opinions! I personally think that HSPA+ style technology is where the industry should be headed, but would like to hear other opinions!
I've put up my reasons for HSPA+ and will add reasons for both HSPA+ and LTE/real 4g as people weigh in. I'll try to give credit when I can to the original poster. So far, as I am a fan of HSPA+, I have no reasons for LTE/real 4g yet! I might get this moved to the Android General section eventually, as I think it would be interesting to see the overall viewpoint of the XDA Community!
Yes, I know that this might attract trolls/flaming, but lets all try something - don't feed them! Ignore them completely. This strategy has proven to work quite effectively. I think we could all get some insight from a good thread like this.
______________________________________________________________
Reasons for HSPA+:
1. So much cheaper for them to put into place.
2. Speeds (on 4g networks I have used - NY, Dallas, Portland, dozens of other places) are always north of 3 mbps down and 1 mbps up, all you really need for any kind of laptop tethering, and certainly more than you ever need for netflix on your phone, and definitely way more than you need for browsing sites on your phone (good websites nowadays even with plenty of pictures are small size).
3. It doesn't suffer from the constantly low signal issues of real 4g (i.e. no signal AT ALL inside of buildings - this is what I have seen from multiple people who have traveled with me - I have 4g when they have 2x or whatever the hell edge is for them).
4. Super cheap for our provider to upgrade, passing savings on to us in the long run - in some cases, all the tower needs is a firmware upgrade. At worst, fiber optics lines are needed in order to facilitate the faster speeds needed.
5. In "real" 4g phones, you have to turn something on to access your faster speeds? Really? I know, bit hypocritical coming from a guy who has rooted his phone and flashes roms, (for the record, I've only flashed G-lite after rooting!) but I bet the average consumer doesn't realize that they have to turn it on and never uses it. With HSPA+, it might not always be really "4G" when the icon says "4G," but at least we don't have to turn anything on - we just have to be in signal range! If you really want to know, you can get a widget (or modify the good ol' framework-res.apk ).
6. Furthermore, BATTERY. Need I say more? From the numerous people who have managed to get LTE signal I have traveled with, the BATTERY DRAINS LIKE WATER OUT OF A... SOMETHING WITH A HOLE IN IT. Ridiculous. Don't know about you guys, but even when I had low signal strength HSPA+ at work all day long, my battery would fall maybe 30% over 12 hours of light use on the stock unrooted rom.
7. Also, HSPA+ has freed up a lot of the 3G network for T-mobile - it is a fact that T-Mobile's 3G is now a bit faster than before. QUALIFIER - The same would technically apply to the real 4G networks, but remember, those networks see less time as users have to activate 4G on their phones to utilize 4G and therefore free up 3G.
Reasons for LTE/Real 4G:
skinien said:
- Theoretically, can achieve speeds faster than HSPA+
- LTE bands being used by at&t and Verizon are in the 700 MHz range.
I bolded the item that I feel is most important. The battery life issue will be a draw when LTE is more mature and chipsets become more efficient. However, the only comparable HSPA+ network to LTE is T-Mobile and they operate in the 1700/2100 MHz bands. The lower the frequency, the farther the signal can travel and the better the building penetration. The fact that the signal can travel farther means that carriers can upgrade/enhance networks faster and cheaper (less tower maintenance).
If battery life and speeds are equal, I want the best signal.

Can someone confirm that LTE does currently have better building penetration? I have not seen this happen to my friends with LTE, though my experiences certainly are not a large enough sample size. This question is raised in the question section below.
dhkr234 said:
-LTE eliminates the dual-protocol nonsense required for carrying a voice channel simultaneously with a data channel. A properly implemented LTE network will rely on VoIP services to deliver voice communications, maintaining ONLY a data network connection.
-LTE eliminates (at least it can...) the link between voice services and network provider. A proper LTE implementation will allow you to select your voice carrier separately from your data network, so you could rely 100% on, for example, google voice or voip.ms, the network provider is turned into a simple data channel.
Regarding the signal drop you mentioned in LTE, this isn't a problem with LTE, but rather a problem in the DEPLOYMENT. It does take time and money to put up the equipment and get a properly balanced network. There can also be issues regarding the utilization and availability of spectrum -- are those signal drops by chance associated with running LTE over AWS? Or are they running it on much more robust 700 MHz?
Click to expand...
Click to collapse
If the link between the voice service and network provider could disappear, that would be very interesting! The point was also raised that currently, because no voice runs over LTE, the 3G/2G/whatever radio has to remain constantly on in order to ensure that voice calls can be received/sent. This results in a faster drain of the battery, obviously, and may be a simple barrier to overcome.
______________________________________________________________
Questions!
The question still remains in my mind, however - is LTE (in its current state) still a huge battery hog even without both radios on at the same time? Because while I know as it matures, I'm sure radios may become more efficient - but you can only make things more efficient to a point.

Updates:
Some great responses here! I haven't checked back in a while but you all are putting out some really worthwhile stuff that has made me rethink things. I will keep my original opinions (should they one day change!) at the top, however, just so we have a full record of everything.
I am removing references to LTE as "Real 4G." I knew from the get-go that it was indeed not, but considering how far off that is from the cell phone market, I figured we might as well call it that. However now I am not!
I added current Questions/Updates sections.
I added some good reasons for LTE - I know these reasons have been listed more than once before, but these were put together the simplest! Keep giving your opinions, this is very useful data for people to know!
I totally agree with you, I've been tempted to move to an lte network but its all a money sucking strategy, yeah you get awesome speeds that make you drull but at the end you'll drain all that data package in what? 2 weeks if not less, since some people really download and abuse the network on their device, I rather have a steady HSDPA+ than a money/data sucking network

Right now I'm on a wimax 4G network but sprint is going to switch to LTE soon like Verizon has and I heard the 4G is supposed to improve a lot more and cover a wider range on LTE. I'm hoping my next device will be LTE based so I can get good stong 4G coverage no matter where I go
I think LTE is only for cdma phones and HSPA is for GSM phones. I could be wrong but both Verizon and Sprint are cdma. I've used HSPA before and it's ok but nothing to really brag about. I can't really compare it to LTE because I have not owned a device that supports it yet.

Nah, LTE is sim based (gsm) just like the rest. You're thinking of wcdma which is different (aka UMTS and up) but still gsm tech. CDMA/EvDo/WiMAX is a dead technology soon enough.
I agree, tmobile should just stick with HSPA+ until LTE tech is improved. They can roll it out slowly and is an easier upgrade (smaller leap than 2G to 3G) for them. It's just a costly one. I heard that they are selling their towers and leasing them back for a short term cash solution. Not sure if it's to pay off some impending debt aquired by DT or to pay for LTE upgrades for tmousa...
My suggestion is stick with HSPA+ (3.9G), skip LTE (3.9G), and go straight for LTE-Advanced (Actual 4G). Both HSPA+ and LTE are not technically 4G, they are just marketed as such. LTE is a much better network technology than HSPA+, but it's not all there yet. LTE is much more efficient in using the frequency spectrum. Also you can only do data on LTE, no voice at the moment. Not sure about LTE-Advanced features but I would assume you can do VoLTE-Advanced just how Verizon is planning VoLTE.
I will agree AND disagree with you. LTE is not directly advantageous to the end user but its benefits are passed down through the operators which will take a few years to become apparent. Its more a technical upgrade with the operators back end network and towers. I'm pretty sure we had the same thoughts when UMTS and HSPA started deployment.
LTE is a shift into a different mobile telephony architecture. LTE will be completely packet switched so in the long run, the infrastructure and tower implementation will be simpler. Using different frequencies and radio modulation, it probably wont be as simple as put an LTE base on an existing tower so it going to take a while to sort out coverage. The end users advantage comes from the more efficient spectrum use increasing capacity with better handling of devices when under heavy load. Frequency chunks are variable so operators can tweak speed / capacity depending on location or cell size. Radios will eventually mature with battery life becoming better with every generation. I have no experience with LTE so am not sure how calls / data is handled or battery life.
HSPA is a mature technology with plenty of real world experience, radio's and towers that have been tweaked over years for speed, latency and battery life. It is also relatively cheap to deploy as the back end connections already exist and the tower kit is "mass produced" shall we say. However, HSPA is quite inflexible requiring 5Mhz frequency chunks which may limit capacity in urban areas. Battery life on HSPA is achieved mainly by cheating, handsets sit idle at UMTS (3G) until data is transferred and often calls are dropped to 2G when possible.
Being from the UK, its probably going to be 2014 / 2015 until we see LTE as they are still "conducting trials" and the licences are scheduled for 2013 i think.
Please feel free to correct me or add to this, I just wanted to add my opinion to the mix.

Nah, LTE is sim based (gsm) just like the rest.

Verizon is cdma, so how is lte gsm only??

Verizon LTE phones also have CDMA chips in them. They use LTE for "4G" data and CDMA for voice and 3G data. They will be a GSM carrier once they drop 3G support and switch fully to LTE.

Interesting - you have a good point here, especially when comparing the maturity of the two types of networks. From what I've been reading here and everywhere else, "real" LTE is clearly the more advanced tech but just needs time to develop and in the long long run will be better. Hm.

No wonder my phone hasn't been staying on full HSDPA (or HSPA+) when it's on idle and only goes on HSDPA ONLY when I'm using it and idles at UMTS when I'm not. I was wondering about that lol. Oh well knowing how HSDPA and HSPA+ is, it's probably a lot easier to transfer from HSDPA to UMTS to EDGE to GPRS than switching from LTE to 3G and 2G connection types.
I skimmed thru and someone already said it:
LTE is not "Real 4G". As of right now, a tech spec for 4G does not exist.
http://en.wikipedia.org/wiki/4G
If you consider that LTE is "Real 4G" then **** it, why talk about 4G? Lets talk about "Real 5G"
http://en.wikipedia.org/wiki/5G
LTE(not 4g):
Don't have even a good card yet,
Still is not on total.
get signal lost sometimes
Speed is great but with the signal lost...

Your 5G link don't have almost any new information.
Lets talk about what was asked in this thread.

From the Wiki article:
However in December 2010, the ITU recognized that current versions of LTE, WiMax and other evolved 3G technologies that do not fulfill "IMT-Advanced" requirements could nevertheless be considered "4G", provided they represent forerunners to IMT-Advanced and "a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed.

in othewords, it's akin to saying, "i'll let you call it 4G as long as you promise to make your technology reach the original specifications. Pinky swear k?"

Really, there are saying "you can call it 4G as long as its better than 3G".
I agree its BS, and the ITU obviously caved to industry pressures. But based on this statement HSPA+ and WiMAX are technically "4G".

Suits me just fine - use the best available tool for the job, that's what I say! Voice calls and texts don't require a battery-sucking HSPA connection to work well
Where I live it's tmo 4g, or nothing. Literally there is no other 4g for my region. Nuff said

yup, i was pretty annoyed when the ITU caved to corporate pressure because they needed to rebrand 3G into something new...
Oh well.. I still call today's 4G standards as FauxG. probably wont consider it 4g until they meet the original requirements.
I just have really one question on this hspa+ <> 4G etc. I read that t-mobile is working on bringing HSPA+ .84, which I guess is 84mbps (theoretical limit). So if a 3G speed actually is the same speed as the current 4G speeds does it really matter what they call it? I would prefer they advertise the speed, because for me it is the speed not the tech behind the scenes.
