HSUPA?

So, will the captivate have HSUPA?? It says on the main page here on XDA, in the specs breakdown, next to HSUPA it says, NOT IN US.
I could have swore i read that it WILL have it?
I have an iphone 4, and have become accustomed to the crazy fast upload now, but i wanted to pick up the captivate to tinker with an android phone.

Everything I have read so far has said it is supported, but now that you mention it, what would be the difference, a certain frequency band I guess? Nothing I have read over thus far has said anything about a difference between countries (i.e. US and rest of world)...

Not sure if this is fast enough for you but unless AT&T massacred the radio in the Captivate you should experience speeds like.... http://twitpic.com/24a5ri
That's my Galaxy S in Orlando running solely off 1900MHz 3G.

FWIW, this indicates HSUPA is supported, but I'd consider this a preliminary spec that needs to be confirmed after the Captivate is released and tested.

Sweet, very nice.
Seriously, once you have HSUPA, you cant go back. Its like going back to edge.
I still think i'm going to hold out about a week or so after the device launches just to make sure of a few things that i need to have.
thanks fellas!

Can we bring this back for discussion again?
From what I understand, when you are on HSUPA you will get an H in the status bar instead of 3G. Is anyone seeing this? So far I haven't seen this and speedtests have agreed that I haven't had HSUPA. I had an iphone 4 before and I know it was on HSUPA in the same area.

Yes. If you look at my picture posted here http://twitpic.com/24a5ri you will see the 'H' you are asking about in the statusbar.

My phone says I'm on HSDPA but I only have the 3G icon on my screen. Do you only get the "H" when you have the high-speed upload? Seems a bit counter intuitive to me.

I've read somewhere awhile back that it fluctuates from showing 3G to HSDPA when it's active on data transfer and hits/detects the higher speed...don't hold me to that though. Maybe someone else can offer more insight into it but i've actively seen the icon switch from 3G to H with not interaction by me (background data i assume)

Well that's weird. I'll have to play with it more tomorrow and see if I can figure out why mine won't jump on HSUPA.

Okay, so at my house, where I know I got HSUPA on the iPhone 4, I'm definitely not getting it now on the Captivate. I have a signal strength of -51 dB, so I know I have enough signal. I couldn't get much higher signal if I sat under the tower. I'm wondering if I have a problem on my phone since trinikartel got HSUPA just fine.
I'm new to Android, anyone know something to check for this?

Well trinikartel said he was on a Galaxy S, not a Captivate. I'm thinking the US versions dont have HSUPA. I have another thread on here stating that I got 2457 down and only 174 up this morning. Also, I've never seen my 3G turn to an H.
Also, I dont know if it matters but on my 3G icon the down arrow is orange and the up arrow is green.

I think you guys don't realize that AT&T's HSUPA is still broken. Don't you remember that whole upload fiasco? It affects the Captivate as it does the iPhone 4 and it hasn't been fixed in those markets (apparently most) where they use the Lucent equipment.
I used to get great HSUPA upload speeds on my AT&T banded N1 and the upload has not been fixed as uploads are still stuck at regular 3G < 300kbit speeds.
The Captivate undoubtedly supports HSUPA, but AT&T's network is still borked and as far as I can tell they have not rolled out any fix.
I have both the N1 and the Captivate.
The only other thing I can think of is if AT&T is turning off the HSUPA based on the phones IMEI or model number.
Just checked with an iPhone 4 friend, can not get over 200k -300l, so there is still a system wide HSUPA failure as far as my limited testing in my market is concerned.
Used to be 1.6mbit up quite regularly on the N1 or the iPhone4.

Oh, I didn't see him say that. That sucks. I really hope the Captivate didn't get crippled, but right now, there's no other explanation than that. I SHOULD have HSUPA right now, and I don't.

I never had an issue where I live. While everyone else was going slow, I was still doing 1200-1300 Kbps.
Edit: Looks like there's a good chance the Captivate WAS crippled. There's absolutely no mention of HSUPA in the manual at all. This REALLY sucks. I may consider returning the phone because of this and leaving AT&T.

Its all 3g hsdpa/umts

AT&T devices do not show the H like the International versions, they use 3G icon only to avoid confusion apparently.

Well on AT&T's site it says the iphone 4 has umts/hsdpa. I'm pretty positive that it has hsupa. So I don't believe AT&T's site is an accurate source of information for their own products.

I just put my sim card back in my ATT Tilt2. It DOES show H in Dallas, TX. As it has since I bought it. Captivate shows 3g. There IS a speed difference.

I live in NYC and just ran a speed test. I'm getting 1.52 - 2mpbs down and .19mbps up. While my friend on his iphone 4 sitting right next to me is getting 3 mbps down and 1.8mbps up. This phone definitely slower. And when I tether the speeds go even slower. Is phone really crippled?

I'm getting about the same right now (at night I can get 4M down). The thing is that I'm getting the same crappy upstream speeds with my Nexus One. Before the whole AT&T equipment ****-up in early July, I was getting ~1.5M up with my Nexus. Now I'm wondering if they crippled it for non-Apple devices.

4G not implimented yet!!?? plus more

ok i havent seen a post for this so here we go..
if you use adw launcher and custom make an icon attached to the hidden menu apk you can access the test and servicing menus like other phones BUT... if you go into test settings for phone (play around its in there) there is a menu the shows hspda (3g, hspda+ being 4g) and many other functions that are advertised on the phone that are all listed as NOT IMPLIMENTED YET!!
so as far as i can tell 4g is NOT active on tmobile at all yet. not until the software is upgraded (gingerbread i am assuming). so it would make sense why the signal on the phone is screwed up and dropping (confused phone maybe?) and why im still getting 3g speeds (slightly faster maybe from better signal reception due to upgraded hardware from my previous Vibrant).
go take a look for yourself and let me know what you think. im sure you can use desktop visualizer to get to the menu to. DONT MESS WITH ANYTHING THOUGH. i had to reset my phone and not with a hard reset, but a recovery i found on a nvflash website. almost bricked it. so just look but don't touch anything important unless you know what your doing.
im looking forward to hearing what everything thinks of this and the giant list of other features also saying this in the same menu. because i feel mislead just a little bit.....

I think it's just that the functions in the hidden menu aren't implemented yet.

Hmmm, interesting find! Maybe this explains the problems I'm having maintaining a stable 2g only connection as well

I've got a hot 4g connection where I am (west Texas), you don't get 4.9-5.6mb (Speedtest) download on 3g. Did you check the T-Mobile coverage map to see if you have it in your area yet?
Edit: you also may need a new sim card. Depending on the age of the card, you might not be able to get a stable lock on to 4g (age as in what generation it was produced.. not how long you've had it)

thats possible, but im getting 3g speeds still as far as i can tell and i don't see why it wouldnt be included in the "hidden menu" if it is working since we aren't "really" supposed to know about the hidden menu. anyways just something i noticed.
menu is Hidden Menu->modem settings is where the menu is at.
and i got a new sim card (tired 2 new ones both the same) and yes i am in salt lake city and it is a 4g area for tmobile. but seems like everyone (mostly) is getting signal drops all over the place. my 2g isn't working as consistantly as it did before on my vibrant either. im sure gingerbread will fix all of this though.

I'm getting 4-8mps down in Metro Atlanta. I say 4G speed is on.

I'm having the same problem, and I've even got a 2G booster in my house. My 2G connection drops all the time on my G2X but not my Vibrant. When I look at the signal strength when it's up it's not much different than the Vibrant, -104dBm on the G2X vs -100 dBm on the Vibrant

Im at a consistent 6-9mb dl at my house with a 1mb+ ul. Im calling it 4g and have you tried your conn outside of your city to see if its just congestion on the network?

I'm also getting 4-8mbps speeds in Atlanta, 4g is definitely working.

I'm in vegas, every hour, I get only 10 or 20mn of 4g at 6Mb download speed, the rest of the time I'm on 2g. At night time,i get 4g most of the time. So I guess in the day time, they kick me back to 2g to save their bandwitch, I'm returning my phone to let them know this is not acceptable

My phone SAYS 4G all the time in Charlotte NC but I have only been getting 1mb DL and about 1.5 upload. The weird thing is that browsing the web is lightening fast compared to the vibrant. I would say it loads pages twice as fast.

Not sure but this may have as much to do with the processor and RAM speed as the connection speed.

I get crap speeds compared to the Nexus S, and that phone doesn't support full hspa+

I am not complaining about my speeds which are plenty good IMO, averaging around 3-3.5 mbps. However, I have been surprised that they are no better than my Nexus One was that also didn't support HSPA+.

A few things, before we get too heavy handed on the FUD:
The phone is technically '4G' compatible, and it supports it out of the box.
Most of T-Mo's towers have been upgraded to support their 4G (HSPA+)
Regular HSPA caps out at about 3.5Mbps down. I've gotten as much as 7Mbps down on my G2x
Personally, I haven't had many issues with signal, but I live in Houston, so that may have something to do with it.

4g is on in Huntington Beach, and irvine.
I did notice its not a huge difference speed wise though. I had the moto cliq 3g and i would get 1mbs ish to 5mbs DL, and with the G2x im averaging about 3mbs to 7mbs. not a huge difference but the big change is Latency. I used to rock 700ms to 1000ms on 3g with my cliq, im getting around 55ms to 150ms on my G2x.
Latency is key for me though, i would prefer lower latency than higher download speeds. Due to the fact I need to vpn and voip with company network.
I found that t mobiles 3g network is still very capable in speed. the main issue i had was my cliq was underpowered to handle the t mobiles network. when i would tether my rooted nook color it would perform like a champ.

Where do you live? Is it possible T-Mo may not support HSPA+ in your area?
It's also important to note that even if the towers you're connected to support HSPA+, that's only one part of the process. They also have to upgrade the data connection to the tower itself (backhaul) to ensure it can handle the speeds. If you're connected to an HSPA+ tower that doesn't have the upgraded backhaul, that could explain slow speeds.

No.
HSPA+ ("4G") is on and working. You're just not in an HSPA+ area it seems.
We're all getting faster than HSPA speeds, so we are certainly on HSPA+. Speedtests are the best way for you to verify if you are on EDGE (2G), HSPA (3G), or HSPA+ (4G).

I would like a 3g icon just top know what type of tower I'm on, I think the baseband is wack, I bet when gingerbread comes out we will get the separate icons... Also my vibrant would get steady 5-6mb down 2mb up, but with this phone its anything but steady, I can get up to 8mb down but its crazy random, regular use is sometimes slow initializing, and someones websites timeout.... I think a baseband upgrade will fix all this stuff tho, or software upgrades.

That's the thing though. The way T-Mo has their network setup, if you can get 3G from a tower, you should be able to get 4G. Period. You may not get 4G speeds, but you're technically connected to an HSPA+ tower, and thus the 4G icon. It'd be weird to connect a tower that supports HSPA at this point, but not HSPA+ (though I'm sure there are some out there)

[Q] Never gotten 4G speeds before - phone related?

I got my phone in May 2011 and have used it all over the San Francisco bay area where supposedly there's good 4G coverage. However, I've never gotten 4G speeds before either with stock or CM7. The only time I've seen the 4G icon on CM7 was a bad commit on a nightly. My best test speed is around 500 kbps. Signal strength is always good though.
Is this a network saturation problem or could it be related to my specific device? I do have the newer SIM card that came with the phone.

make sure your network settings are not forcing edge only... thats the only thing i can think of...

Remember this phone only has HSPA+, which is technically classified as '4G'. So make sure you check out the HSPA+ phones and not LTE phones.

Yah if you don't have the "use only 2g" un-checked your not gonna get 4G speeds.
The only things you should be getting on your phone is 2G/4G because technically 4G is the same as everyone elses 3G. Just different throttling parameters i believe.
Anyhoo, try another ROM...if your still on Froyo 2.2 then go for Ultimate ROM and go from there.

Tmo rep at the store said to try the new baseband to see if it helps (I have the March baseband). Other than that, everything checked out OK. Since they're not doing exchanges on this phone anymore, I can hang on until a better device comes along.
Thanks for everyone's input though.

whats wrong with nexus s 4g

hi all. I myself have a moto atrix 4g on att. i am familiar with rooting unlocking bl and flashing. so i decided to help my friend with his nexus s 4g unrooted, locked, on stock sprint 4.0.4 build IMM76D, baseband D720SPRLC1, kernel 3.0.8.
last night I unlocked bl, rooted and installed cm9 posted by burnsra as I saw it was the most popular cm9 by replies or views. now all this started because my atrix was having double the reception compared to ns4g in everything wifi, network, data. so i thought cm9 would do something good here. but after installing it successfully the wifi signal is at 2 bars the data reception is at one bar, the 4g reception non existent.
Is there any new baseband that would enhance the reception of wifi, sprint network 3/4g?
right now I am on baseband D720SPRLC1.
test i did: i installed speedtest.net app on both phones. i was 10 feet from my home router N with no walls, doors in between. ns4g was always 5-7 mbps download, slower than atrix and almost 2mbps slower in upload.
never mind for data speed. ( i know its apple to oranges, att/sprint) but still atrix was 10 times faster on att hspa+ than ns4g on sprint with 4g on.
wifi and network bars are most of the time at 2 bars.
is there anything left to do to make it better in reception?
any ideas suggestions are welcome.
thanks

You can try different basebands. Depending on your area, whatever you flash can either improve or worsen the signal. I've heard Sprint doesn't have the greatest in terms of 4G speeds. I'm no expert on network speeds and such, but I think it also have to do with whatever technology is being used for the networks. HSPA+ is gonna be faster I believe. My G2 has faster download speeds than my NS IIRC. I haven't done a real world comparison lately. I think my G2 was getting like 10 down a few years ago on campus. Lol. My NS only gets like 5 or 6.

Actually, you answered your own question ... it is an apples to oranges comparison. Wimax download speeds of 5-7 sound about right, and uploads will be slower. There's no question that Sprint is way behind AT&T and Verizon with their advanced data networks. In the meantime, what you experienced is just about all there is for now. The LC1 radio is the most current.

omg now I understand why I pay a little bit more on att network.
anyway is there any combination between kernels and basebands that might give some better reception on ns4g?

There really isn't anything that can be done to make much of a difference. I flashed the latest CM9 nightly, checked my 4g speeds and they are in the 3-4 range ...and I can see the Sprint tower across the road. Most of us who are hanging onto Sprint, in spite of the service ... are doing so because of the unlimited data. But, Sprint really needs to break out the LTE soon, or there may be a massive exodus.

Sprint's "network vision" and their excuse for terrible 3g

I have called Sprint on their BS and their horrible 3G.
Evo Shift = EVDO Rev A
Photon Q/iPhone5/newer phones = EVDO Rev B
Ping time on Photon Q = 800ms+ latency
Download speed = 0.02Mbps
Evo Shift = ~300ms latency
Download speed = .5Mbps
http://community.sprint.com/baw/thread/99267?start=360&tstart=0 <-- iPhone5 users having the same problem.
I switched back to my Evo Shift 4G. Apparently every tower is "down" in my area while they perform the upgrades. OVER IT.
Link above spells it out

One, EVDO Rev B, last I checked, is not on the Photon Q or any LTE phone other than the iPhone 5. Two, EVDO Rev B IS NOT AND WILL NOT BE DEPLOYED BY SPRINT OR VERIZON. All phones connect to EVDO Rev A.
Those speeds and pings are highly varying, make SURE both phones are connected to 3G (EVDO). It seems the Photon Q is connected to 1xRTT rather than EVDO, while the Evo Shift is connected to EVDO.

Yea I've been contemplating returning my Photon Q as well (still have a few more days in the 14-day return period for Costco) or selling it outright. I wish I had made the decision before last Friday when I could have picked up a GS3 for $50...
I have my Evo Shift on craigslist for sale, and thus returned it to stock, but am thinking I may unlock it again, try out CM10 on it, and if it runs well, switch back too. LTE would be nice, and even though I'm in the Atlanta metro, and get LTE speeds driving around, it seems to have dead zones at my house, my buddy's house, my wife's school, and anywhere else I might have the opportunity to use it. I was hoping some of the development would help fix these issues, but I guess I'm too impatient to wait lol. One of the last straws was going to watch a video on collegehumor that wouldn't run on the Q, even with Flash 11.1 sideloaded, but runs fine on my original HTC EVO (which also runs CM10).
Dunno, its a hard choice... the keyboard is really nice, and I'm excited for the free vehicle dock, and the dual core 1.5 is pretty sweet, but there are just too many issues with the thing...

To me the downside of Sprint's network is that the connection seems to drop out often, resulting in the inability to load data at that instant, and probably battery drain... i would think anyway. Does anyone else notice the connection dropping and reconnecting a lot? I felt like i maintained a much more steady connection on T-Mobile's network. And yea, i find Sprint 3G to be pretty slow.
But in the few times i've had strong LTE, i've had the fastest speeds i have ever recorded anywhere!

Yes, the Photon is NOT getting Evdo (whatever rev) even though it says it does. Both stock and post OTA.

I've noticed the exact same thing. When I'm on 3G, the data is fairly regularly just dropping for a second or two at a time, so anything that requires a constant connection (like IRC) will crap out. The few times I've been in 4G, mostly in silicon valley, I've gotten ridiculously fast speeds. Last time I ran a speed test it was like 36MBps down and 20MBps up. I never saw those speeds with Verizon (but that's likely because so many more people were actually using Verizon, too)

yeah the dropping connection is terrible, and happens even in a real strong 3G area. could it have anything to do with looking for LTE, or being on the edge of an LTE zone, or just the fact that the whole network is in flux? hopefully it's only temporary 'cuz it's pretty bad... seems real slow too, especially on downloads.
yeah, my record speedtest was 37 MBps down in LTE! i never got 20 up tho. yea, there can't be too many people using Sprint LTE yet, but i've been reading some forums on the site s4gru.com, and supposedly Verizon just raced to cover the nation with LTE, but didn't rebuild their entire network like Sprint is doing. who knows, but at least Sprint LTE seems promising.

yeah, my record speedtest was 37 MBps down in LTE! i never got 20 up tho. yea, there can't be too many people using Sprint LTE yet, but i've been reading some forums on the site s4gru.com, and supposedly Verizon just raced to cover the nation with LTE, but didn't rebuild their entire network like Sprint is doing. who knows, but at least Sprint LTE seems promising.

That is a bug in 77.8 (drop data when changing network mode)
workaround: turn on airplane mode, turn off, or reboot phone.

i think these are actually 2 different things, i've been seeing the signal drop/reconnect ever since the original software version. after the update, the 3G icon will disappear(like after a phone call) and won't come back until you toggle airplane mode or it drops and reconnects on it's own(which seems to be often!). but if your 3G icon disappears and you have bars, try and you should see that you can still load data, so i believe that bug since the update is more of a cosmetic thing. at least that's how it is for me, and others have said the same on other forums.

Here's a screenshot where i have no 3G icon but have a perfect data connection!

You're right, that issue actually does have a lot to do with the phone wanting to search for LTE, or trying to prefer LTE when the connection is very weak. The solution? Turn off LTE when you're not in LTE coverage. Not the most elegant or pleasing solution, but that fixes it.

Yeah, that could be it for me. I switched to CDMA-only a few hours ago and haven't seen the signal drop out once. I'll keep an eye on it tho to make sure. It seems like LTE is creeping in around where i live, so my phone may have been wanting to connect but was just out of range of it.
