Turning on HSDPA?

I've seen screenshots of Captivates homescreens from you peoples showing an H instead of just 3G. May I ask how you enabled this? Thanks in advance!

HSDPA and 3G are the same thing (i'm pretty sure)
or more technically speaking, HSDPA is one half of 3G, with HSUPA being the other half (HSDPA=download, HSUPA=upload)...
can anybody correct me if i'm wrong?

You're correct. AT&T requires all its 3G phone to display 3G instead of any other icon. Often times, ppl find ways to replace it with the native 3G icon, H, which is widely used by rest of the world. But that makes no difference in actual connection speed.

this is correct. when referring to both of them together they are commonly called just HSPA.

"3G" is the common short abbreviation for UMTS. HSDPA is an update to UMTS that gives faster download speeds (a version is widely deployed on AT&T). HSUPA is a protocol upgrade that enables faster upload speeds (installing HSUPA equipment borked upload speed on AT&T recently). Combining the two is called HSPA. HSPA+ is an update to HSPA that's even faster. T-Mobile is planning on rolling this out. LTE (AT&T's 4G pathway) is totally unrelated to HSPA.

Thanks for your replies! I appreciate the schooling

This is the correct post.
Also, I'm certain AT&T doesn't disallow the H icon because I've seen screenshots of the Captivate with that icon.
However, at the same time, I have a -51 dBm signal and no HSUPA which I know I should be able to get here because my iPhone 4 got it. Something is going on, but I'm not sure what yet.
Edit: Nevermind, it sounds like I'm wrong. In the manual there's no mention of an H icon. There's also no mention of HSUPA. I think we just got screwed by AT&T. What a surprise.

I'm pretty sure AT&T does disallow use of the H icon. They did on my Fuze. The reason is that there's ALWAYS confusion when people don't have a good operational knowledge of the protocol names. There's always someone on the EnergyROM or Cyanogenmod threads asking why "only" H comes up when they expect 3G.
Anyway, I have an AT&T band Nexus One as well as a Captivate. The N1 is definitely HSUPA compatible. I just tried speedtest.net a few times and got an average of 2.5M down and 175k up (5 runs no run over 256k) in midtown Manhattan. On my Captivate I'm getting ~4M down and 200k up. Upload speeds are about the same, probably limited by AT&T's current (under) capability.
I don't have access to an iPhone 4, but if you do, could you do a few runs on the speedtest.net app on both devices from the same location and let us know the results? At this point, I'm pretty convinced it's the HSUPA equipment screw-up at AT&T not lack of HSUPA on the phone.

That's what I was saying. My iPhone 4 got HSUPA here with no issue at all. When everyone else's HSUPA had issues, I still had no problem at all. So unless HSUPA decided to die in my area the day I returned my iPhone 4, I don't think the Captivate has it.

When did you return it? The iPhone 4 was released on June 24 and the AT&T HSUPA issue cropped up around July 6th or so. That's when my Nexus went from over ~1M up to ~200k up. If you gave it up after July 6, what sort of upload speeds were you getting? What sort of speeds are you getting now on the Captivate? Not trying to grill you or anything, I'm genuinely curious.

HSUPA

I've looked all over the internet and cant find any place that confirms or denies that this phone is HSUPA compatible.
I did a speed test this morning on my way to work and got 2457 down and only 170 up. Thats a pathetic upload speed. I'm guessing from that speed that the phone is not HSUPA. But AT&T has been having problems with their HSUPA software since the iphone4 launched and maybe my low upload speeds are because of that?
With that low of an upload speed it'll take forever to upload photos in MMS or to facebook and would take a lifetime to upload a 720p video to youtube.

i can tell you that the upload is pathetic compared to my iPhone 4 in the same apartment. Download speeds are comparable, but upload seems to cap out around 150k.
On my HSUPA iphone the uploads cap around 1.1mb

It doesn't have HSUPA. Or if it does, it's not turned on. Let us only hope that the radio supports it and an update will turn it on.

From your phone type *#0228# and it should show that your connected to hsdpa or umts.

No, on the box it just says quad band GSM and lists the bands and then it says tri band umts and lists the bands. It doesnt mention hsdpa or hsupa on the box.
Plus, with AT&T's network crapping out on hsupa right after the iphone4 launched who knows what the problem is, possibly the phone has it but the network is broken.
Really, with as much as I hate AT&T, I'm thinking they are crippling upload speeds in congested areas because certain parts of the country are still getting hsupa speeds on their iphone4's.

The first number changer between 16 and 8 others numbers stay 1
FWIW First number went to as low as 4

HSUPA is currently tuned off in many (most?) AT&T markets right now until they address a so called software issue.
Nobody ready about this?
I've read of someone on their captivate getting over 1mbit, and that is obviously HSUPA, but I don't think he was in an area where the lucent equipment is in use that is causing the AT&T upload issue.
Ooops, I guess someone pointed this out...

Samsung US website does not show this on a feature Captivate or any other Galaxy phone

I haven't seen anyone who has gotten HSUPA speeds on a Captivate. On a Galaxy S, yes, but not a Captivate. HSUPA works fine in my market, and always worked fine on my iPhone, but never on my Captivate. It just doesn't look like it has HSUPA, or at least it's not enabled. Hopefully it's something that can be turned on later, but I wouldn't be surprised if it never is. If this was an AT&T decision, then I'm very disappointed, but not entirely surprised.

I just installed Atinm's Kernel w/HSUPA on my captivate and here are my before and after speeds.
1402 down 247 up
2142 down 1662 up
I was already running cognition 2.1.5 with the voodoo only kernel.

In a letter responding to a complaint I filed with FCC the AT&T representative stated
"In regards to the issues with HSUPA speed; HSUPA is disabled from all AT&T handsets and is currently only available on our aircards. We also do not market the Samsung Captivate as a HSUPA capable device.
I am sorry for any inconvenience this issue may have caused you."
She didn't deny that it, or their network were capable because then she would have to admit to the problems they are having with bandwidth volumes that servers can't keep up with. A similar problem that U-Verse is developing/creating for their formerly content DSL subsribers in my area.

All handsets but the iPhone 4. At least its a semi-honest answer.

HSUPA works on 2.1 (with HSUPA hacked modem file).
i'm not sure i should downgrade back to 2.1 , i really miss the HSUPA on froyo 2.2

Install Cognition Beta 8.
Or an i9000 ROM.
Both are in the Android Development forum.

This is old news.
Several who complained to FCC about this back in August got very similar responses from AT&T.
I received a case regarding your concerns with the data connection speed for your Samsung Captivate.
In regards to the issues with HSUPA speed; HSUPA is disabled from all AT&T handsets and is currently only available on our aircards. We also do not market the Samsung Captivate as a HSUPA capable device.
Did they enable it only in the iPhone to offset disappointed followers?
Several custom ROM available here to you enable this feature with great results.

htc inspire with FAKE hspa+ ??

that is like car company sent out new cars (next year model) to reviewers but without the key! cus the engine is not ready yet?

I think the main purpose is to get the phone out and reviewed before the iPhone 4 goes to verizon. I personally care about battery life and os before it being faster than my current technology.

most people want this phone cus it' HSPA+ otherwise if you just care about battery or OS, just get a phone with 1500mzh battery (samsung captivate). haha

Myself could care less about the network speed. Theres a lot more I like about this phone than hsdpa+

HSPA+ is a touchy subject these days. As we all know, all HSPA phones benefit when AT&T and T-Mobile increase their network speeds and backhaul. It really comes down to network congestion and how far away from a tower you are.
I have a friend who's on T-Mobile who gets better download speeds at his work (about 3 miles away from mine) with his Nexus One than I do with my HSPA+ capable T-Mobile G2.
Most older phones are capable of HSPA speeds up to 7 Mbps. So until T-Mobile and AT&T crank up the download speeds to 21 or 42 Mbps, most people will not see much of a difference between HSPA+ phones which are labeled as "4G" and your run-of-the-mill 3G handset.

so it' another ATT BS lie?
on att.com it said "evolve faster with speeds up to 4x faster* then at&t's already fast mobile broadband network"
i have not seen 1 speedtest anywhere that shows inspire able to get real hspa+ speed!
how you know it' not another samsung? (get it? samsung with fake gps, htc inspire with fake hspa+)

I think it hspa+ capable. Yes ATT 4g is probably not fully launched. I also dont get why a 4g phone is released without 4g speed. I get dl speed of 3mbps in Houston. Houston has very good ATT service. Very consistent all areas in Houston. I am very curious how consistent 4g is here in Houston. However when we have 4g it will be a upgrade from 3g. I was planning to wait for the phone til its offered for free. I just don't have the urge to replace my N1.

The problem is the phone is definetly capable of the faster speeds it is just that AT&T at this time does not offer those speeds. Even with their 3G phones, the phones are very much capable of faster speeds then AT&T networks are putting out.

Obvious troll is obvious.
Maybe you should wait for the phone to come out before talking smack about it. Let's see how things pan out after the thing officially launches.

Ok guys arguing about this is pointless. Lets all calm down. Most times when The phones are sent out for review they are just that "Phone Reviews". When the network updates are ready then they will most likely due a new review comparing the 4G networks. There is alot more to a phone then how fast the connection is with the cell provider that can sway some one to decide to buy the phone.
As I can see this as heading to the flame war section I am gonna close this up now.

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.

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.

no, but there are radio chipsets that can do both. I don't think the infuse has this chip. and the infuse is not spec'd to have lte capabilities.
2g,3g,and 4g are just marketing terms that are supposed to give a general idea to the consumer how fast it is.

That's somewhat more believable - e.g. the hardware is capable but the radio baseband isn't yet.

Chatted with another AT&T tech support Jesus. According to him, "Infuse can run on both [HSPA and LTE] ... It is a phone designed for this transition since 4G level speeds are available with both LTE and the HSPA networks. And the Infuse can access them both. The Motorola Atrix as well ... I am not able to find documentation that is not proprietary. The information I have, since LTE is only in testing stages, is that LTE compatibility is not posted on the Specifications. The 4G speeds are currently being provided by an enhanced version of HSPA and HSPDA, and the phones are connectible. The 4G phones, such as designated the Atrix and the Infuse, will be able to access LTE once it becomes established via a software upgrade."

the motorola xoom is lte upgradable so ther eis a posibility that the atrix is as well. this says nothing for the infuse. t-mo had the 4g flag on there hspa+ devices months ago and they cannot be upgraded to lte. it is a marketing game that started with sprint (wimax isnt all that fast compared to hspa which can run at 14.4mbps, hspa+ can run at 42mbps but att is only willing to supply 7.2 and 21mbps respectively http://www.intomobile.com/2010/06/04/data-speed-showdown-sprint-4g-vs-t-mobile-hspa/) 4g just means that it is faster than 3g was, infact wimax is barely comperable to 3g with hspa on many gsm networks. the 4g flag offers no garentee that it will support lte on any carrieer other than verizon. att reps often speculate and talk out of there assses, many times the information comes from customers and not corperate.

The infuse supports the highest speed of lte and hspa that ATT has out now and it will support the fastest they have by the end of 2011. My ATT Rep (for work) told me so and has one herself.
Edit: btw, my att Rep, represents my entire district, highly doubt she would talk out of her ass, but I do agree that the ones u find in the stores r mostly untrained

There' no way. If the Infuse were capable of LTE they would have advertised the hell out of that. Unfortunately reps aren't engineers and clearly don't understand the technology. Now the infuse may be capable of the fastest speeds, i.e. equal to whatever the LTE network is limited to, but it's not connecting using LTE.

i believe att will wait for the tmobile acquisition to finalize before releasing lte devices so they can use as many bands and cell towers as possible, easing network load issues and increasing coverage speed and reliablility.

Most of the population would raise a brow if u even mentioned the terms HSPA or LTE. They didn't advertise it because spending that much money to advertise a feature that only 5% (guesstimate) of the population knows about isn't the brightest idea.

Verizon built an entire ad campaign around LTE
http://androidcommunity.com/verizon...-its-the-most-advanced-4g-available-20101122/
And I can't seem to find the ad with the kid in the store, but they definitely push the fact that it's 4G LTE upgradeable. If ATT could, they would.

Agreed...
As you point out in your next post, carriers do not shy away from using technical terminology in their advertising. Further, even if this were the case, one would expect LTE connectivity to at least be listed on the spec sheet. Not only is it NOT there, but it was not on the sheet I saw back when this thing went to the FCC. I'm not a lawyer, but assuming what was posted was what the FCC was looking at, I believe AT&T would be in violation of the law if this thing supported LTE.

DING DING DING!
We have a winner!
HSPA+ and LTE are NOT the same thing and the radio bands have little to nothing to do with which tech is used. Remember when AT&T had their last Mea Culpa moment and enabled 3G on the 850 MHz band? (Because it penetrates buildings better)
If the Infuse *is* capable of LTE, that's news to everyone. It would be on Samsung's Spec sheet. The manufacturer would want to announce ANYTHING that it's capable of.

I'm from the SGS2 forum and we're having this debate too. A leak of the new 2.3.4 ROM that's supposed to be released at the end of the month has APN's for AT&T's LTE network along with PNGs of their unique LTE logos. So whatever version of the SGS2 AT&Ts releasing, it will run the same ROM as the international version. So, based on what you said about the "tech," what do you think what I just shared means? Is adding the 700mhz frequency to an existing radio all that's necessary to access LTE? Could the existing radios already support the frequency but have it disabled? No one really has a lot of info on LTE so it's kind of a mystery.
Here's an interesting article...
