Problem with HSDPA

Ive noticed that the H symbol doesnt actually show hsdap availability. For example, when I have 3g signal but there is no data transfering I have a 3g symbol with arrow next to it, as soon as i start transfering data it changes to an H even if im connected to a 3g cell with no hsdpa functionality, (confirmed by a speed test).
Any ideas how to actually show whether i am in HDSPA coverage or not?

Why do you say that your not in a HSDPA area or signal range? Just because your not getting really fast speeds? Most HSDPA speeds are from 300Kbs-1.5Mbs when that little 3G changes to H your are most deffen... getting HSDPA

well ive done speed tests when it says the H and it varies between 200 and 300 sometimes.
Is that normal?

Yes just because the Max Download speed is 3.6Mb that does not mean you will come any place close to that. there are so many factors that will throw the download speeds off hell the wind blowing from the west and not east the window being closed and not open you get the Idea

I've been confused by this as well and while speed is clearly better with the "H" on than with 3G, I never go above 450kbps which is a bit slow, 3G tops out at 340kbpw. I wonder how efficient the Qualcomm chip is for 3G+, I hear that Samsung i600 users are getting speeds of 600/700 in the same area.

HSDPA icon stuck!

I turned on my Tilt this morning and where the 3G icon used to be it is now a H icon all the time even if I am not connected to the network or downloading data. I have tried disabling HSDPA and reenabling it, but that hasn't worked. Disabling and reenabling the icon itself also doesn't get rid of the problem. I haven't installed anything. Does anyone know how to fix this or is this some kind of newly discovered radio bug?
Running on AT&T network.
Thanks

dont complain.. ur not stuck in H u now have full blown H in the area.. my girls 85 has full H now and so does my tilt

does this mean I have HSUPA too?
What exactly do you mean by full H? My download speeds didn't change at all

I am currently faced with this same stuck H issue.
I am running the stock AT&T ROM ver ... 1.62.502.0, Radio version 1.37.14.09
Sometimes when I travel to a particular work office I use dutty's 10 button Comm Manager to turn 3G off. This particular office is built like a fortress and I barely get signal inside. If I leave 3G on my battery is dead in a matter of hours.
So I turned 3G off for the first time since upgrading to this ROM, and later when I turned it back on I find I have a constant H indicator rather than the 3G I normally see.
Yes I am in an HSDPA area, but normally I would only see the H when downloading.
Yes, I use direct push with a hosted exchange server.
I've tried disabling HSDPA in KaiserTweak, and I get back to the 3G indicator ... But as you would expect my download speeds are limited to 300 to 400 kbit/sec.
With HSDPA enabled I average twice that, with bursts over 1mbit/sec.
Can anyone speculate why I have the constant H indicator now instead of only when downloading?
Everything still works, I just wouldn't mind knowing why I am seeing this change in indicator.

I have since found out that the the contant H icon is a result of AT&T upgrading their network. Since then, my download speeds have roughly doubled. Turns out the contant H is a good thing.

I went away on a business trip for a week and now upon returning I too am seeing the constant H, whereas previously I'd see 3G which would change to H and back when using data.
But that's not the part that is worrying me.
The problem I see is that the data connection is active all the time; it never drops. So besides the large H indicating HSDPA availability, once any data connection is made the 4 bars plus plus small triangle changes to 4 bars plus small H and *never* changes back. In the past I'm pretty sure the data connection would come and go as needed.
Is this bad at all? Seems like it would suck battery power to have the data connection active all the time. It's as if the KaiserTweak "always on: AT&T MediaNet" is stuck on (but I never actually did that tweak and it is actually disabled in KaiserTweak).
What's going on?

Have you done an upload speed test?
Apparently a constant H icon can indicate HSUPA support.

Little more info ... however finding a map of what was upgraded isn't that easy.

AT&T Nears HSPA
By Brad Smith
WirelessWeek - April 02, 2008
LAS VEGAS—AT&T will have all of its 3G markets enabled with the high speed uplink capabilities by the middle of the year, according to Hank Kafka, vice president of network architecture for the operator.
AT&T had 255 major metropolitan markets with W-CDMA/HSDPA at the end of 2007 and continues to add markets. Kafka said at a GSM Association roundtable on HSPA that AT&T expects to cover 350 markets with 3G by the end of 2008, including all of the top 100 markets.
The operator started installing HSUPA last year and now is in the process of rolling it out, he said. By mid-year, he said all of its 3G markets will have HSUPA. He says typical data rates on the downlink now are between 600-to-1400 Kbps with a peak of 3.6 Mbps, while the downlink typically is 500-to-800 Kbps.
There are upgrades for HSPA which take it as high as 14.4 Mbps and Kafka says AT&T is studying those. But he declined to say when or if AT&T will raise its data rates to those levels.
Kafka also said AT&T has seen significant data usage increases for customers using 3G.

Yea, I have the constant 'H' as well, but I think it's the same as having a constant 'E', meaning that you're connected to HSPA and everything's good.

switching bands
switched bands sometimes helps changing the icons from edge to 3g,to disable HSDPA you need to disable HSDPA through kaisertweak,schaps advancedconfig or hsdpa switch whether cooked into rom or manually installed to switch back to 3g

UK T-Mobile Web N Walk Basic Customers Only

This thread is only for users that are UK T-Mobile customers that have only basic Web N Walk. In fact it might only apply to customers that have moved over to Web N Walk on or after January 2008
I have noticed that my download speeds seem to be teetering at the lower end of 3G, slightly better than GPRS, but no way near HSDPA speeds. The test is located at the following site, if you are unable to use Opera try Pocket Internet Explorer.
www.dslreports.com/mspeed
I have repeated this test at various points throughout the day and with various signal strengths and have never been able to download faster than 190kbit/sec.
I have been speaking to T-Mobile regarding this issue and they state that HSDPA is only available to Web N Walk Plus customers and not the basic Web N Walk customers. However, colleagues of mine are on the basic Web N Walk and are able to download at HSDPA speeds.
T-Mobile are unable to provide written proof stating that HSDPA is unavailable on basic Web N Walk, the terms and conditions do not state this, and the 1GB fair use policy should ensure no one abuses the additional speed.
Furthermore, the MDA Compact IV is sold as a HSDPA enabled phone. I therefore conclude that either I have been miss-sold my contract / phone or T-Mobile have incorrectly disabled HSDPA.
What I would like to do is see if others using the MDA Compact IV are in the same situation, so could you go and do the above test if you are a UK T-Mobile customer on basic Web N Walk and report back on what speed you get.

My HSDPA connection is patchy at best, in that the coverage is poor (as is T Mobile in general). However I have just tried the speed test and I got 1157 mb for a 1 MB file. Doesn't really seem representative of my usual speed experience though.

Are you on the basic Web N Walk tarif and when did you move over to it?

Whoever told you this about HSDPA at certain tariffs on T-Mobile is talking tripe I'm afraid. HSDPA is standard on T-Mobile 3G across the UK now, as is HSUPA UK wide and in London area faster HSDPA.
I'm sure you know that the figures are published at best and you will rarely hit what they publish.
In my area I get a four bar signal but at best I get just over 1mb connection with it usually being around the 300-600 mark. Uploads however have seriously improved since the network upgrade a few weeks ago.

I'm on £7.50 w'n'w and the most i get is 300kbps which is the same as when i turn off hsdpa and just use 3g - still 300kbps.
What the hells going on?

Right this is FACT and it IS on terms and conditions, I read them.
The reason I aborted my pre-order of MDA Compact IV was (amongst others) the fact that the standard web n'walk IS 3G speed only at up to 384kbps.
When I found out I flipped and cancelled and rang Orange retentions and got such a blinding deal I stayed with Orange ! Orange = HSDPA any package.
T-Mobile customers in the UK who have been on web n walk basic for ages may be under old agreement when it was HSDPA. You have to be on wnw PLUS now to get HSDPA for new customers.

dont get it, whats the deal? Why not pay another 5 or so quid and have HSDPA?
Afterall, why do you need HSDPA if your just browsing on your phone???? The only real reason you need HSDPA is if your using your phone as a modem which basic package doesn't allow you to do anyway.
This just makes sense.... so, whats the problem? Its not like its 10's of pounds of diference, its the price of 2 pints in a pub?

HSDPA is useful for web browsing simply because the pages load up up so much quicker.
I use mine to do a bit of browsing on the train after leaving work, and the difference when the coverage drops off to standard GPRS along the journey is very noticeable.
To say that you don't need hsdpa for browsing is like saying we could all make do with 56k modems for browsing at home. Yeah sure we could. but it would be painfully slow.
I am on T-mob, but have the HTC version. When I first got it there was no hsdpa on my account. when the phone detected a hsdpa signal, I could not connect at all, so I phoned 150 and asked the guy to make sure that hsdpa was enabled for my account. He said it should be but he would check. When he checked the system it wasn't set up, but he enabled it there and then, and it was available pretty much straight away
I am on flext 20 + w 'n' w basic
I'll try the dslreports thing tomorrow, but pages do load up much quicker when I have a H signal indicated

GPRS is commonly known as 2.5g
3g is "3g"
HSDPA is commonly known as 3.5g
Speed limits for each
btw: i'm fairly sure the phone supports HSUPA with a quick registry setting. Remember also that HSDPA is a BURST technology, not a sustained/constant technology.
Just because you dont have a "H" in your bar, doesn't mean your getting slow speeds - 3g IS quick enough for webbrowsing. You get normal 3g connection on Web'n'Walk basic.
So my question still stands, why do you NEED 3.5G HSDPA speeds for webbrowsing when 3G (Normal) IS way fast enough? If I was T-mobile I would use the same method for discouraging people using the phone as a modem when they are not supposed to - mind you 3g is still waaaaay fast enough for most stuff.
The fact you couldn't connect when your phone shows a H in the bar is odd... glad you got that sorted out.

I was on the basic package, I have not requested to move up neither have I been told that I have been moved up. The potential difference here is that I was on web n walk before Jan this year.
Good luck in trying to sort this out. i've decided to go (back) to Vodafone at the end of my contract in Nov because T mobile network coverage is so shocking.

did a few speed tests on mine this morning:
on the train
GPRS - 37 kbps
HSDPA - 498 - 1514 kbps
at my desk
HSDPA - 778 - 1231 kbps
was on web n walk basic for two years before upgrading to the diamond

and your trying to tell us 37k/s isn't fast enough to render webpages? If your experiencing slow webpages with this speed, its not your link at fault.
edit: at its at least 3x faster than you could dream of on a 56k modem!

Everyone who has responded so far has been on the Web N Walk package before Jan 2008. I would like to hear from someone who has only recently moved over to Web N Walk.
@ Monty Burns
1. There are better was to ensure that Web N Walk basic customers do not use their phone as a modem, such as a fair use policy, which they have. Why restrict how fast someone gets to that 1GB limit!
2. Yes back in the day 56K seemed fast, but you got to understand that the bar is constantly moving, back them most pages where static HTML, these days we have java, video streaming, audio streaming, not to mention bandwidth intensive apps such as Google maps.
I do notice the difference between what is effectively 3G speeds and WiFi. It’s frustrating and T-Mobile should see common sense and allow everyone to use HSDPA, it doesn’t cost them any extra to do so.
@ ns73
Please point me in the direction of the terms and conditions you read, as I cannot find this anywhere!

yes your correct, the bar is higher but .. why do you need 3.5g to do it? 3g is way fast enough and will happily fill up your phone very quickly!
I suspect there is some form of limitation to HSDPA connection/s which is why, if i was t-mobile, i would limit it to those paying for the full package. As your only supposed to be browsing, you just don't need 3.5 when 3 is still massive overkill.

I remember few years ago when HSDPA just came out I rung up T-mobile and they had to tick the box for HSDPA enabled. I believe you can also do this yourself by logging into the T-mobile website and managing your account

You don't get HSDPA with standard WNW, and while it may not have been stated when you connected, it was also not stated that you WOULD get HSDPA. If you connected to WNW over a year or so ago you may have slipped the net, and still have access at the higher speed.
As far as "ticking a box" is concerned, I don't believe this option is still present on their' systems, and even when it was it was simply for legacy purposes and you should have never have had it ticked in the first place.
The £5 isn't much extra to get the HSDPA, I don't mind paying it.

Exactly. Cough up and get the larger packet (about 2 beers a month!!!? If you can't spare that, you have more serious concerns), live with no HSDPA (why do you need it anyway when your not allowed to use it as a modem) or go to another telcom.

well i've just taken out my compact IV on tmobile, flext 30 with W+W my signal at home is shocking, but at work connects over HSDPA and returns between 992 and 1324 so far, just with standard and new line taken out on tuesday

@ Monty,
I have to disagree, while you may feel that 3G does fill your screen quickly enough, I find it slow and tedious. Everyone is going to have their own opinion on what they consider to be acceptable. I do not consider my current browsing experience to be acceptable.
There is a limitation to the number of connections per cell station. The cell station has algorithms built in to automatically share the data between HSDPA, 3G, GPRS, and GSM. However, this ratio is adjusted every few milliseconds on the fly and would only be a factor if a large number of people are downloading at the same time.
@ lx_t,
This option is no longer available on the T-Mobile website.
@ OK!
Your right WNW basic does not state that it includes HSDPA, but neither does any of the other WNW tariffs, so in that case as its not explicitly stated one way or the other, it is implicitly implied. Furthermore the MDA Compact IV is sold as a HSPDA phone, it does not state that this is subject to being on a particular WNW tariff.

Thats not the link. you cannot notice the diference between 3g and 3.5g on a web browser on your phone... unless the web page has tens of links to some seriously high megapixel pictures of course but then, the phone would cave in anyway.
Check out the link i posted above for the speeds. 3g is like using a ferrari to race a push bike when it comes to speeds needed for web pages. HSDPA is designed for "modem" use and heavy downloading and for web browsing is like using a Veyron.... if you think 3g isn't good enough, your never going to be happy with web browsing on a phone.
I've spent more than £5 pounds worth of my time trying to explain this and thats all it would cost you a month to get a little more priority on the t-mobile network and a higher fup. Why are you so cheap? Why should you get maximum speeds on cheapest package? its FIVE pounds.
Now, where's the nearest wall, i think it might be less painfull head butting it than this thread ....

Question about 3G

Alright, so from what I gather, EV-DO Rev A. is 3G, according to Sprint's map, I have Rev. A in my area. I have seen screenshots of peoples phones, and they specifically say "3G" however, I have never seen mine switch out of EVDO.
My question is, is it normal for the CDMA Hero to only display EV, while the GSM Hero displays 3G? Or is my phone just stuck in Ev-
do mode?
Average download speed is ~120KB/s, peaking out at ~140KB/s. Maybe I'm just use to broadband, but that doesn't seem very fast.

Yes its normal,

When you see Ev or EvDO on your phone you're getting 3G.
The GSM Hero shows "3G" because most (if not all) GSM carriers refer to HSPA (their equivalent of EvDO) as 3G.
You might be seeing some CDMA Hero screencaps with the 3G icon in the taskbar because some ROMs have the other icon. Really it doesn't matter as long as you know that, whether it says 3G or Ev, it means your data connection.

It is in the android software to display EV if you are on EvDo. The GSM Hero is actually on 3G, so it displays 3G. Although EvDo is technically a 3G network, it isn't called 3G.

Well, that answers my question. I expected 3G to be faster though.

Same here. I have noticed that the speed can vary with the signal strength, though.

I'm getting the 120KB/s with 5 bars, in a central area of town. Only towards the middle of the night, and very early morning can I get up to 150KB/s. (throughput, number of active users, etc.)

I get around that as well. The scary thing is that Sprint is faster than my cable internet O_O

isnt EvDo just what sprint refers to there 3G, thats what i thought. just wanted to add my 2 cents =]

I would say this is unusual. When you say you're getting 120 kb/s, are you talking about your speed during the actualy downloading of a file, or your connection speed? Using my hero, wifi tether, running a speed test my d/l is about 1.1 mb/s. My actual speed when downloading a file is usually about 360 kb/s.

No its 3g, 3g means thrid generation thats it. So evdo rev a is sprints thrid network type

That's the peak speed of anything. Rapidshare, Megaupload, Torrents with a high seed to leech ratio. 120 is as high as it gets.

Keep in mind if you run a custom rom, a lot of them are ported from GSM, which displays a 3G icon. On the dachstar 2.1 ROM I run it shows 3G instead of EV just because my the icon wasn't replaced with an EV one.

question....
when I tether....
speed test say anywhere from 300kbs to 1.2mbs
but.. you guys are saying..
surfing the web on the phone is only less than 150kbs?
why is that??

careful in using kb/s and KB/s. they're all different.
kb/s refers to kiloBITS per second, while KB/s refers to kiloBYTES per second. if i'm correct, its 8 kilobits per kilobyte, so to get your KB/s speed, take your kb/s speed and divide by 8.
when you're wifi-tethering and downloading something in your browser, it usually displays as KB/s (kilobytes per second). you probably won't get above 120-140 KB/s using wifi tether, downloading something on your computer.

+1 haha I was just typing this same response. Also, just like wifi does, evdo slows the transmission rate as signal gets weaker in order to keep it working. So basically your speeds will be slower as signal is weaker.
3g is just a blanket term for all the different mobile broadband protocols which have been deemed third generation. Also, to complicate things, evdo rev 0 is slower than evdo rev A, so just because you're on an evdo tower doesn't mean it's a rev A tower. (and the tower might have high usage, which can slow speeds too)
Also, file sizes are typically displayed in kilobytes, while connection test speeds are usually in kilobits

[Q] Very slow 3G data speed

I have problem with my captivate such that 3G data speed(according to Speedtest.net app) does not go over 300-400 kbps. Also app chooses closest server as Wichita Kansas and I am in in Portland Oregon.
Besides the speedtest app Internet browsing is slow in general even though signal is good ,3-4 bars constantly.
About 1/2 mile away from my work place ATT has put new 7.2Mbps tower but even in close proximity of the tower my download speed does not go over .5 Mbps.
I got new SIM card at ATT store but that did not help either.
BTW phone is rooted
Any suggestion would be appreciated

The tower is 7.2 megabits. Your theoritical speed limit is about 1000 kbps so...did you try intalling the hsupa modem? Be warned that it will screw up bt and headset controls
Using the power of the force close

Have you tried the speed test multiple times? I verified my tethering with really high speeds which were cut dramatically the next morning. It could be time of day or just lousy network congestion. Try again over wifi and compare to your computer for a benchmark.
Sent from my SAMSUNG-SGH-I897 using XDA App

On wifi there's no problems at all. But seriously regardless of the time of the day or location I do not get anything better than average EDGE speed even the phone shows 3g icon constantly. Is there some APN setting that I need to check.
I compared the download speed to iphone4 , 3gs, HTC ARIA and motorola q9h on the same time of the day and on same location and captivate gets at most 1/3 of download speed of the other 4 phones. (Other 4 phones get in average 1.2 Mbps download)
Not to mention that even that speed is actually low for HSDPA. I did not flash HSUPA since I'm not so concerned with upload speeds
