Captivate and 4G

Was reading in another thread (which was closed while I was writing a reply) that some people here might be confused around what 4G is and whether or not their Cappy can be upgraded to it.
First, the simple answer:
Your Cappy cannot be upgraded to 4G. Now or ever. It is possible that it could be upgraded to HSPA+ with the right software. But that is not 4G. 4G is a different radio access protocol running at different frequencies.
The longer answer:
The source of all this confusion is T-Mobile's marketing department who claim their HSPA+ network is 4G. 4G is not HSPA+ or anything like it. It is 3.5G. Much like GPRS and EDGE were 2.5G. LTE (the real 4G) is far superior to HSPA+ for several reasons regardless of the bandwidth claims. Mainly 4G will not suffer nearly as much from congestion like 3G HSPA / HSPA+. It is that same 3G congestion that motivated AT&T to turn off HSUPA on our phones. It's because AT&T's 3G network (UMTS, HSPA, and HSPA+) is already heavily congested in many markets.
Only posting this so people don't think they can get true 4G on their Cappy. It won't happen.

AT&T is also marketing their 4G service as HSPA+, with LTE technology entering their network late 2011.

Yes, they've started down that path as well. Just don't expect 4G speeds on any of these "4G" devices unless you're the only smartphone user for miles. I truly wonder what AT&T and eventually T-Mobile will call their LTE networks. 4G 2.0?

From AT&T:
Not all 4G networks are created equal. AT&T is the only carrier that will offer two layers of network technology delivering 4G speeds – HSPA+ and LTE.*
Why does that matter?
When combined with enhanced backhaul, our HSPA+ software upgrade is expected to deliver speeds up to 4x faster than ordinary mobile broadband. And we'll be evolving to even higher speeds with the planned initial launch of our LTE network in mid-2011. When you're traveling on our networks, you'll enjoy faster speeds and a smoother, more consistent mobile broadband experience overall.

So is HSPA+ just a software upgrade with no hardware enhancements in the cellphones or towers?
I do understand the reasoning behind AT&T doing HSPA+ before LTE as it offers reasonably fast speeds in areas where LTE has not matured. If it is indeed only software based, I wouldn't mind seeing an increase from HSPA 7.2Mbps to pseudo "4G" HSPA+ 21Mbps (although these speeds are "up to") on the captivate. Will HSPA+ be up to 21Mbps right out of the gate?
My brother uses epic 4G on Sprint, and in areas of no 4G wimax, his 3G speeds are abysmal... Has sprint stopped upgrading their 3G and is only concentrating on the expansion of 4G?
According to that, AT&T's HSPA+ will end up faster than Sprint's 4G (3-6Mbps on average and up to 10Mbps) unless they pick up the pace.
For LTE (5-12Mbps) according to Verizon.
So is 4G labeling the technology once fully matured (Up to 100Mbps for both LTE and Wimax) or current speed being delivered? Because Sprint and Verizon do advertise their current technologies as being "4G speeds" which AT&T can defeat if their HSPA+ (56Mbps matured) is 21Mbps out of the gate.
The way I see it is that 4G speeds have never existed and should never have been advertised (started by Sprint), but the technology to get there is currently in the building phase.
First post, so I can't back up the speed claims with links directly to Sprint and Verizon 4G speed pages lol
And please correct me if I'm wrong on anything... I'm here to learn.

4G isn't that far away I think AT&T is playing it safe with the 4G in the future thing. I have a couple friends that install att towers and phone lines they have been crazy busy establishing the 4G network in the major cities in know for a fact that most of Dallas and Ft. Worth will be 4G ready this spring as for outlying areas that will take some time. But if you live in a big city area expect your LTE right off the bat

LTE is not 4G it still falls under the 3G umbrella along with WIMAX. 4G technologies can do 100M down.

Does anybody else remember this?

Just thought this could help a bit.

I just need to clarify one more point in addition to OP's post:
Even though HSPA+ is merely a software upgrade in the carrier side (towers), so far it is not the case with phones. So far there is no phone out there that can be software upgraded to take advantage of HSPA+'s higher speed. T-Mo has to release Galaxy S 4G phone to get 4G support. HSPA+ towers offer backward compatibility with current 3G phones but it doesn't mean you will get higher speed by default (much like 11n routers supports 11G and 11B clients but only 11n client can reach the max bandwidth).
And no, HSDPA + HSUPA does not equal to HSPA+.

Only according to a few people within the ITU. 4G is LTE (and for a few sorry sorry suckers, it is WiMAX). Or at least that is how everyone in the industry sees it (outside of T-Mobile USA and now AT&T and a bunch of confused customers).
As far as speeds are concerned, we should treat Mbps throughput ratings with a grain of salt. Those are ideal world, no contention data rates which when taken out of the lab are purely theoretical. HSPA+ is an upgrade. LTE is a whole new set of radio access, backhaul and core technologies.

My friend has a "4G" LTE phone from Verizon and he got 4 or 5 mbps while I got over 5 on HSPA.

[Q] Does anyone have 4g yet?

I have been hearing many things about "4G" launching march 1st. Then once that passed I've been hearing middle-end of March. Has anyone actually been getting speeds of about 6mbps average, not just a peak times. Also if you have go to setting about phone and then network and look at network type and see if it says hsdpa+. The most I ever got standing next to a tower was 5.10 Down and .42 up on stalk, not rooted. I'm starting to think that this AT&T 4G is BS and is just crap advertising like T-Mobile "4G"

I live in Dallas and we are suppose to be in a "4G" area and my speeds haven't changed. On a good day, 4mb down and 1.5 up.

I'm also supposed to be in a 4G area according to their coverage map but I don't see any improvements. Does the 4G map show 4G with backhaul or is it just where the towers are upgraded but backhaul still needs work. Since in all their compercails it says 4G available in limited areas when combines with backhaul

There are only a few 4g areas up, they are:
Cali "bay area", Greater LA, Greater Dallas TX, Buffalo NY, Boston MA, Providence RI, Baltimore MD, Charlotte NC, and Chicago IL.
The 4g areas can be found here: http://www.att.com/network/#fbid=ZfECQbHFsTm

Here's the coverage map with where I live as well as the 4G with back haul crap website (see attachment)
Shoot just noticed you can't really read the works on the website but it says that future mobile broadband to be available by march 31st. I live right where the arrow is pointing to.
Also click on 4g FAQ and look at the questions about the H+ Icon

Im in the bayarea not not seeing any top speeds non rooted. I live in Dublin Ca and the speed i just got was 1705 up 325 down which is about how its been for 3 weeks. When i go into settings the network reads HSPDA but no plus. ATT coverage map in the bottom corner says this is for 3 g not 4g.
Anyone know if there is more to the backhaul in the sfbay area or is this it? Nowahere near the speeds advertised.
Also anyword on ATT releasing ghe cap on the upload?

Actually the map does show 4G coverage if you scroll over. At the top it says that. And from what I've read AT&T only mentioned enabling it on the Atrix they never said anything about the Inspire. But I would think that if they enable it on the Atrix they will on the Inspire, but the question is when. It took them 5 months to release froyo for the captavate and aria after the carrier released it so I wouldn't hold my breath.

I live smack dab in the middle of downtown San Francisco, 5 bars of good ol fashioned HSDPA... NOT 4G... not sure what the deal is with SF, and how they can advertise it as being launched already, but clearly it's NOT.

Thats what I'm saying. The phones are called 4G, I see their 4G commercials, but no one sees 4G on their phones. People are asking them whats the deal and they don't respond to anything. I called them yesterday to ask why I'm not getting any 4G speeds and they blamed it on my phone. I told the rep that I went to the AT&T store and tested the phones their and they got slow speeds as well. She said that 4G will launch in the summer. Do they train these reps at all?

I think they train em about as well as they trained the techs to build out the 3G network in 2008 and 2009... great they made 3G iPhones without having a 3G network, lol.

Same situation here in Baltimore.
Not once have I ever seen HSPA+ show up in the About Phone/Network menu or the speeds to indicate otherwise.
I call BS on AT&T's whole operation.

They should at least tell people that they won't see 4G speeds until ___________ not show a fake 4G coverage map and call the phones 4G. I am covered by their "4G" and get slower than 3G speeds. Wow I'm glad I purchased a new 4G phone. The thunderbolt is looking real good.

I get legitimate 3G speeds in SF... really decent 3G speeds, but I bought the "4G" phone to get the 4G speeds, otherwise I could have just stuck with a 3G phone.

Per the NW page, only HSDPA, not +
They were taken at different times, you really need to look right before or after a test to see at that time.

I dont know if im right but, i dont think we will ever see hsdpa+ or hspa+ in settings network. The big question is, has anybody from any network, seen any gsm 4g phone display hspa+ or hsdpa+ on network connection? I live in puerto rico and my provider is Claropr and i have hit 7,8 and almost 9mb dl and 2mb ul here with the inspire, and all it shows is hsdpa. And yes we have hspa+ rolled out since december!

ATT claims they will remove the upload cap in the future, but no date of course. Personally I think the capped upload speed is very critical as I think upload is more important. Counterintuitive.

I'm rooted with flashed radio, so my signal strength icon is only an H, no +
In the settings I am on HSDPA
I was pulling about 5.5Mbps average down, 1.5 up as of a few minutes ago. My initial tests yielded 4-6Mbps down, 1 up.
Maybe it's finally on here in the NYC area?

Your probably right. I don't think that we will ever see a + but it will show with speed. Does anyone know any app rooted or not that will show a plus if your connected to hsdpa+ or if this is even possible?

hsdpa vs umts

Ok so I bought an HTC inspire 4G and it has hsdpa network and I'm normally getting 2.3 Mbs download. I went into the ATT store and the Samsung infuse uses utms and it was getting up to 5-7 Mbs download speed.
I read other forums that said hsdpa was suppose to be better. If so can anyone please explain it to me. I'm all about network speed and I wanted to know if I should just get the infuse or will the hsdpa improve later on.

Hsdpa will get faster speeds once its turned on in your area. For example in Austin, Texas I get 6mb down with the inspire. The Infuse also has hsdpa. In some areas utms is faster. I'm a huge HTC fas so I will always choose HTC over other brands. If your leaning toward Samsung wait until the Galaxy S 2 comes out for ATT.

Overall you will not feel much of a difference on the phone... you can have a nice and fast looking speedtest but the difference will be within seconds.

agree on that

att stores also setup their own in store micro cells so it looks like they have phenomenal service when you try stuff out in stores.

I'm getting about 6M down, 1up in good coverage area
I am speaking HSDPA with AT&T in east suburbs of Portland, OR. I do hit 7M down though somewhat routinely. Giddy / tingly when that happens . Oh and phone is still totally stock. Since Gingerbread OTA reportedly coming in a couple weeks by this forum, gonna wait until after that to root...skert...never rooted before, but I'm fairly certain I will at some point.
Edit: With Inspire 4G

I've had UTMS coverage on my Inspire 4G...
I saw it one time when I geekin over starting to get such high speeds, and checking what kind of network I was on a lot in the >About Phone setting. There is a youtube of a dude with an Inspire 4G when testing network speeds (and *****ing that it was slow...probably because HSDPA was not turned on in his area yet) that had this show up on camera. He acted surprised and didn't know what that meant. So my conclusion is that Inspire 4G supports UTMS...why I duuno
EDIT: The youbute video where a guy has UTMS coverage on camera on his Inspire 4G is entitled "Is AT&T Misleading about HSPA+ on the Inspire 4G"...well I'm happy with my speed so whatev's.

I was getting speeds like the OP with HSDPA at first
but lately i think AT&T has been sprinkling the magic "4G" dust on the towers around here, because my speeds have obviously improved dramatically, and the HSDPA status hasn't changed...

UMTS = 384 kbps.
HSDPA = 3.6 Mbps (much higher lately on att).
So I'm not sure what was happening with the phone you saw.

I wasn't speed testing when I saw it it in my About Phone menu. I was in my employers cafeteria showing someone else where to check for what network one is currently on, and I saw the UMTS on my phone. Only saw it one time. The video name I posted is about how the H+ icon(in his opinion) is a sham, because it doesn't specify "3G". When he popped about settings it was on UTMS was visible in his About Phone menu. He made some comment about he didn't know what that was all about.

[Q] Data speeds?

So I know all the issues with older 2g sims affecting speeds, I called tmobile, and they said that I was in fact registered with a 2g sim, so I had them activate the sim that came in the box, but I have no improvement in speed. I'm still getting nowhere above 2mbps, most of the time around 1. I know I have a 4g data plan, they added that when I got the phone for immediate activation, not next billing cycle. Even in areas where my old mytouch 3G slide got 4 mbps on the 3G HSPA network, I can't get much above 2 on the HSPA+ network. What gives? If the new 4g sim and data plan aren't working, what's the issue here? Anyone else having issues?

Are you sure that you're connected to HSPA+? And, even if you are connected with good reception to a HSPA+ tower, that doesn't mean that the tower has good bandwidth backhaul. If its a low traffic tower, T-Mobile might not want to pay for a large amount of bandwidth for it.

I suppose I can't be positive, but the icon says 4G. Although I've never seen a 3G icon, only G, 2G, and 4G, meaning they probably just replaced the 3G icon with the 4G icon since the phone can't technically display a different icon for HSPA and HSPA+, can it? I've never seen a 3G icon so I might just be connected to 3G. But even in populous areas, like downtown, at night, I top out at 4, MAYBE 5 mbps. I've heard people getting 4 or 5 on a bad day, 7-8 average and 10-12 if they're lucky. I'm wondering where that's at, maybe it's a flaw in the stock rom and an AOSP or other custom rom would be better. I seem to remember having bad speeds on sense on my Slide too.
During data transfer, I went to the about phone>network menu, and mobile network type reads HSDPA and then reverts to UMTS after a period of inactivity. It does not specify HSDPA+ though, it just says HSDPA. I understand that the 3g and 4g networks on tmobile are technically one and the same, HSDPA+ is just an advancement of the 3G technology, but I'm wondering if something just isn't clicking and the phone isn't taking advantage of HSDPA+. I checked the coverage map, and the entire region I live in, minus a few rural areas, are supposed to be covered by 4G data.

Is 3G faster then 4G?

My fastest tests I took with Infuse were on UMTS network, ranging between 6000 and 6500 kbps. I beleive it's a 3G, right?
Immediately following it from 1000 kbps to 6000 kbps were HSDPA tests (I assume those are "4g"?)
I took about 30+ test in different times, different networks. But top 9 speeds by download were on UMTS network following by HSDPA network.
What gives? If this is a current state of affairs, then I'd rather just lock to 3G and save battery.

Lo should have been forced to hpsa+ when you enter data no matter what. All the tests were on 3g just some happened to be faster. By the way our 4g is not 4g only lte is. Its a gimmick lol. And one thing suprising is regular 3g and this Plus stuff is the same stuff just having more bandwith for it to go faster.Uses no more battery.

No, this is consistent. There are way too many tests to consider this an accident. See results below. Umts is faster then HSDPA on 30+ tests I run so far. As you see in locations they are all different, also different parts of the day as well. Sample is too big to consider this an accendal observation.

My fastest tests I took with Infuse were on UMTS network, ranging between 6000 and 6500 kbps. I beleive it's a 3G, right?
Immediately following it from 1000 kbps to 6000 kbps were HSDPA tests (I assume those are "4g"?)
I took about 30+ test in different times, different networks. But top 9 speeds by download were on UMTS network following by HSDPA network.
What gives? If this is a current state of affairs, then I'd rather just lock to 3G and save battery.

Okay, some clarifications. I'm guessing you're just talking about how it was displayed in your app, but HSPA and HSPA+ are both UMTS based networks, so 3G and HSPA+ "4G" are both UMTS. The difference in this current implementation of 3G and "4G" is that 3G is HSPA which maxes out at 14 Mbps downstream, whereas "4G" HSPA+ maxes out at 84 Mbps downstream. It's the same technology, just basically a software update.
Now, most HSPA 3G phones don't support 14 Mbps downstream. I think most max out at 7.2 Mbps. Most HSPA+ 4G phones max out at 21 Mbps, or some even support 42 Mbps, however, being that AT&T's network is 16QAM, their network's max speed is 14 Mbps. So really, HSPA 3G is entirely capable of going as fast as HSPA+ 4G on AT&T's current network, assuming you have a phone with a fast enough chip in it.
As for the results you posted, I'm not really sure what to say. You said your UMTS tests gave you 6000-6500 Kbps, but then HSDPA tests gave you 1000-6000 Kbps. What's confusing is that whatever app you are using is posting random labels on the network which are all technically correct, but only confusing people. 6000 Kbps is very definitely HSDPA. In it's first release, HSDPA was sometimes called 3.5G, whereas UMTS without HSDPA would have been base 3G. The second release of HSDPA is where we go to HSPA+ and "4G", increasing speeds to 42 Mbps.
If all of this is very confusing, then I apologize, but I'm not really surprised. This is why they apply names like 3G and 4G to it when it's far more complex. If you really want to learn more about the network technology, check out the wiki page for HSPA: http://en.wikipedia.org/wiki/High-Speed_Packet_Access
And yes, as previously mentioned and as you may have gathered from what I posted, HSPA 3G and HSPA+ 4G are the exact same technology, just updated a little, so the battery effect is negligible. LTE 4G will bring an entirely new radio, on top of having an HSPA or HSPA+ radio in it as well, so that's where you get more battery drain. For now, HSPA+ 4G devices won't drain any more battery than HSPA 3G devices.

Boom! Better explanation than me lol. Sorry for my post not being long enough, i am at school. I was trying to get to what he said.
