HSUPA

I remember that it was once touted that the phone would handle HSUPA.
Any idea whether it does?

This should probably be in kaiser general, as it has nothing to do w/ cooking.

thought that it likely needs to be enabled via a rom hack/update.
My Kaiser is currently getting 754Kb down / 320Kb up at the airport in Atlanta (sharing internet via wifi to my laptop)

AT&T is currently in the process of upgrading their network nationwide to support much higher upload and download speeds. Check out this Engadget link. Can you say 20mbps 3G?

ATT is actually refering to the new network as 3.5G it will be available in 20 major metropolitan areas by the end of the year. Regular 3g will be available in 120 new locations in the same time frame.

HSUPA does work and I have used it as it is avalible on the Rogers network in Toronto and Calgary. The TyTN II, Kaiser, Tilt... will always show "E" as in edge, but will flip to "H" only if you are connecting and HSUPA/HSDPA is avalible. Some ROMs have an option to turn on or off the HSUPA feature but the stock Tilt ROM was setup to use that network right away.

This is going to be a silly question, but I will ask anyway. I'm on AT&T. Where I live my game room gets 3G now suddenly. No other rooms gets it but this one. I'm very excited about it. When they do this roll out, does that mean that places that are on the border with 3G like my house, will get engulfed in it or does it just mean that the areas that currently have will be faster. I hope that my question makes sense.
Thanks

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.

Captivate already has hsUpa enabled?

I look at phone status it says hsdpa some times and hspa the other half which I'm assuming means hsdpa and hsupa? Not sure if this means anything.

Can you provide a screenshot of when this happens and run a speedtest and tell us your results? This would be very helpful as many of us, at least myself, do not believe I have HSUPA enabled.

mine is sitting on HSDPA right now... while i'm sitting in bed.

HSUPA is either disabled in firmware or AT&T is actively restict the upload speed for Captivate. Anyway I have never seen my upload speed higher than 300 to 400 kbps. If you have HDUPA enabled, you should see 1mbps upload speed as my friend's iPhone4 can consistently demostrate.
HSDPA is for download speed. If you get download speed over 500kbps, you have HSDPA. Mine can often get to 1 to 3 mbps.
HSUPA is for upload speed.

Yes, HSPA is NOT HSUPA.

thanks for clearing that up... after i posted i did some research on the d and the u... then felt like a moron.. ohh well we only live once.

How can you check what your download speeds are? What app do I use or is it already in the phone?

I like Speedtest from the market. Its pretty solid. or you can go to m.dslreports.com/speedtest from the browser (use the iphone speedtest there).

Well hspa is high speed packet access which can refer to up and down link, how do I screen cap. Or do I need an app for that

I used speddtest and got 1.4 megs download so I guess I'm running HSDPA also

you have to root the phone before you can screen cap.
There is really no need to post any screen cap. Download the speedtest app from market and report your results.

The Cap has HSDPA, but not HSUPA. Do some looking on this forum you'll see where others have analyzed the modem.bin file from the Captivate vs the one from the Vibrant. All of the HSUPA stuff has been removed from the Captivate version. You can get HSUPA on the phone by flashing the I9000 modem file to the Captivate. Data works great, people were regularly getting 1.2Mbps upload. But they had no voice out on telephone calls so it was worthless. Same with the Vibrant modem file. Also, those only supported 1900MHz, not 850/1900 MHz, so if you are in an area where you have 850MHz 3G it wouldnt work at all.
Its been clearly established there is no HSUPA on the phone, AT&T has completely removed it from the software (although the hardware does support it). The last hope is when Rogers Canada gets their version of the Captivate, if they leave HSUPA enabled, that modem.bin file may work on our AT&T Captivates properly since they use an extremely similar network and the its a Captivate, not a Vibrant or I9000. When I said HSPA is NOT HSUPA I meant that just because you see HSPA in one of the menu settings in the phone that is not HSUPA.

ATT 4G and 3G HSPA+ Press Release

http://phandroid.com/2011/01/05/att...s-androids-applications-network-improvements/
The Froyo update for us might give us HSPA+

With all these Android 2.2 phones coming out, it may be even longer before we see the Froyo update. Just my opinion.

Do our phones even have the ability to use HSPA+?

I already get an "h" on my phone where it previously said "3g". No even in a major metro -- Des Moines IA. I use this ROM: http://forum.xda-developers.com/showthread.php?t=856561

yes att disabled this.
that is why we flash to i9000

In this article they say that are devices are not compatible
"Unfortunately, just like with HSPA+ on T-Mobile, existing HSPA-compatible devices will not be able to utilize HSPA+, but AT&T is set to remedy that with a whole lineup of HSPA+ ready flagship Android devices – Motorola ATRIX 4G, Samsung Infuse 4G, HTC Inspire 4G, a Motorola tablet, and others. Overall, AT&T is set to release 12 Android phones in 2011, between 5 and 7 of them being HSPA+."
http://www.androidpolice.com/2011/0...hspa-4g-expansion-12-android-devices-in-2011/
So what you are saying is that ATT is the culprit and our phones are hardware compatible but ATT has forced limitations to neuter our bandwith usage?

That's what I thought, because I was pretty sure our devices weren't HSPA+ capable, just HSPA capable and that it would require the use of different bandwidths and or antennas to work.

What at&t has done is enabled HSDPA and disabled HSUPA which is part of the HSPA specification. The radio in the phone is capable of HSPA speeds up to 14Mbps but not higher AFAIK.
at&t just doesn't release radio firmware that have the faster uplink speeds enabled.
EDIT: Excuse me, the Captivate can't even do 14Mbps. It is locked at 7.2Mbps down and 5.76Mbps up.

Just so you know, HSDPA is the downstream bandwidth and HSUPA is the upstream bandwidth.

I'm well aware of the differences between the two. Although due to the increased upstream speed and thus reduced latency, HSPA tends to have faster downstream speeds than HSDPA alone as well.

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.

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.
