Connecting to UMTS/HSDPA using AT&T

I have noticed that when I am connected to the fast cellular internet the sign constantly switches between 3G to H. Like every 15 secondes.
It's not that the connection is dropping it's just it is always changes from 3G to H. I am on At&T and would like to know if it happenes to someone else.
As I read, At&T suppose to have an HSDPA and since I am in big cities like Chicago and Washington DC, if there is HSDPA it should exists in these cities.
So?? anyone using AT&T + KAISER knows what I am talking about?
should be worried?

i see this behavior all the time with my Kaiser, Trinity and Treo and never worry about it... most often the i'll see the "H" symbol when i'm tethering or downloading a file from a website or i'll see the "3G" or "E" if i'm in an area of town that doesn't have a strong signal... i don't worry about this behavior unless it affects what i'm doing, e.g., lose my internet sharing connection. just my 2 cents...

Thank u for your fast reply. I know sometimes the signal changes to E or even G if there is no high speed connection around but it seems that the H and 3G just changes every 15-20 seconds in areas with high speed connection. does it also happen to you? or anybody else?

I actually consider you lucky. At work in Menlo Park, Ca. I rarely get a 3G or an H... But I spent a couple of weeks going to SF every day and there I saw behavior very much like you describe. For me it seemed to want to switch from 3G to H as I was doing some sort of access like e-mail read or a download. Though that is probably just anecdotal as I didn't really make a study of it; just something I noted.
Cheers.

i have the 3g/H switch happening constantly as well. could this connection issue have anything to do with the sms issues (issue being sms works randomly), or totally unrelated?

Yep...this happens to me too.

I'm in the Chicago-North Suburb area and I see it change all the time too. I get a lot of HSDPA connections. From my understanding, this is a good thing!
Though I'm by no means an expert on HSDPA, 3G, UMTS or any of these, it's my understanding that HSDPA will give you data bursts of up to 5 times the connection speed of 3G/UMTS.

What it means on my 8525
Hi Guys,
Don't worry, you are not having signal quality or connection issues. On my 8525 (Hermes) the switch to H from 3G simply means the phone is using the data connection at the H (HSDPA) speeds. It shows 3G when data is not being transferred.

Yup. It's sort of like a combination power/hard drive light on a computer. When the "H" lights up, data is being read and written over the high speed network. The "3G" means the high speed network is available, your just not sending or recieving at the moment. At the slower EDGE speeds, the "E" is just a power light, showing the network is available, but no indication when you are sending a receiving data over it.

Someone correct me if I'm totally wrong, but here are my thoughts:
The H would be displayed when the device is accessing HSDPA or HSUPA. The D stands for download and the U stands for upload, right? But AT&T only has HSDPA right now, and not HSUPA. So when you're in an HSDPA area and browsing the web or sending and receiving emails, when the device is receiving information (downloading), it's on HSDPA and the "H" is displayed. But then when it needs to send information (uploading), since there is no HSUPA signal it switches to 3G and the "3G" is displayed. Hence the constant switching on the display as the device sends and receives data.
Someone please give me a gold star, or tell me I have no idea what I'm talking about!

Here's a GOLD STAR!!

Not that I'm an expert either but THIS WOULD EXPLAIN IT!
Thanks

If you see the H then you are using HSDPA, if you see the 3G icon then you are using UMTS. The difference is speed and the fact that if you see the H icon it means you can use voice and data at the same time.
I can stream live TV from my Media Center using WebGuide (free) and as long as I have the H icon I can talk on the phone at the same time I'm watching TV but if it switches to 3G I loose my data connection until I hang up the phone.
Mine mostly stays on H but swithces to 3G when the HSDPA signal is lost. HSDPA isn't avalible every where that 3G UTMS is.
Also HSDPA is 3.5G and UMTS is 3G. Meaning with UMTS you can get downloads of 384 kbps to 768 kbps and with HSDPA you can get from 768 kbps to 1mbps.

This is how it is supposed to work kids...
The H only shows up when you are using HSDPA. HSDPA would kill your battery in no time if it stayed connected all the time. your phone is smart enough to only use HSDPA when it is actually sending/receiving data. Think of it as a power saving feature.

I'm in cleveland and i just see an "H" all the time... FWIW...

But it only uses HSDPA when it's RECEIVING data, not SENDING. That's what HSUPA would be for (if AT&T had it yet). Right?
High Speed DOWNLINK Packet Access
High Speed UPLINK Packet Acess

That is correct. HSUPA should be coming soon according to Engadget: HSUPA

Perfect.!! Downlink = Downloading (HSDPA).. Upload data by 3G as AT&T is not supporting Uplink = Uploading (HSUPA)... smart one..

I'm not sure it is that simple...
I live in Jacksonville an i neverget an "H" except when i used shap's rom on my 8525; however, i get speeds from 600 to 980, so is this extremely fast UMTS, or is Cingular just inconsistant with their labels?

I also live in Jacksonville and found with the Tilt that I was only seeing the
3G icon and never the H icon until I installed KaiserTweak and set the HSPA option to enabled. Now I get the H icon but only during the data connection being active (e.g., sending a URL request and receiving the page load). The icon then turns to 3G when the Tilt sits "inactive."

Also just because you don't see the H for HSDPA doesn't mean its not working unless the REGISTY has the correct setting you will not get the H icon. the place is HKLM>Drivers>RIL>EnableHSDPAIcon = 1 (sometimes default is 0 which means you won't see the H icon)

Since my last posts on this topic, I now have my Tilt!
I am confused- why would AT&T not enable the "H" icon? If you are using HSDPA (and soon HSUPA), wouldn't they want you to know it?
Maybe they are afraid it will confuse people. They just want to market "3G" and people to understand it and see that icon, whether they are on UMTS or HSDPA/HSUPA?

Getting the H-icon on the MDA Vario III

I own the MDA Vario III and am very pleased with it. There is one thing however that I stil haven't been able to get working since the Vario II and that is the H icon.
What I want to know is if it is enabled on the Vario III. I know it is on the TyTN II as my brother has that and it showed the magic H icon. Have any (dutch) T-Mobile users here ever have the H-icon appear?

Is in the phone settings 3G net enabled?

Not sure what you mean by that.
3G is enabled as I am getting the 3G icon. What else should I check?

see this thread.
I'm not sure whether T-Mob controls the HSDPA over their network or whether it is solely controlled through a registry entry.
As of yet, the other HSDPA users on this forum haven't been so helpful as I've posted a few queries about HSDPA on a variety of areas, with limited success

HSDPA on T-Mobile NL is not in service yet, but should be available soon. I've only seen the H on my phone once in Dublin, Ireland with O2.

I get a H in UK but I have a feeling HSPDA might be officially setup by tariff. I am on W&W plus if that makes a difference

No, I am on WnW basic, and I get the "H" within london
I dont get it where I live (just outside london)
I did ask T-Mobile (via email)about HSDPA and capped data-rate
High-Speed Downlink Packet Access (HSDPA) (Sometimes known as High-Speed Downlink Protocol Access) is a 3G mobile telephony protocol, which allows mobile networks to increase their data transfer speeds and capacity. T-Mobile currently support HSDPA speeds of up to 1.8 Mbps (Megabytes per second)
Access to HSDPA speeds is currently free on T-Mobile, however the customer will be charged based on the amount of data transferred (subject to Price plan and allowance)

though I worry aboute the "currently free" phrase ;-)

Hi there - I can use HSDPA on my Kaiser too - but ! I only see the HSDPA when I`m locked into data service - what I do want is that when ´`, in the normal phone mode that it not only shows the 3g but the H - does anyone know how to get this ???????????????
Many thanks in advance

HSUPA finally happened today in St. Louis, MO

ok... so i just wanted to post this ... this just happened today, it was not like this yesterday... but my phone has displayed a constant H today, where as before it would only show that when downloading... so i decided to upload some large files to my ftp server, and i used IP Dashboard to monitor the upload... check out my upload transfer rate...

I think the H stands for HSDPA, not HSUPA. The difference is primarily in the upload speed (that's what the U stands for), but most service providers only provide HSDPA at this time, not HSUPA.

U is for UMTS... H is for HSDPA/HSUPA
ATT has been slowly rolling out HSUPA in its major market areas... Did you look at the pic and notice the upload speed?
Previous behavior of the indicator was 3G, would only switch to H when downloading data on HSDPA... now its a constant H and i get fast UP/DOWN access..

Ok, my understanding was that all 3G and faster connections use UMTS, and HSDPA/HSUPA are advancements of the UMTS protocol. The manual only makes reference to HSDPA, so I guessed it didn't support HSUPA.
The upload speed looked like it fell within the HSDPA range, but I'm not very good with the whole kbps vs. kB/s conversion thing!

Can you please do a speed test on www.dslreports.com/mspeed

I live in the St. Louis area and got 600 kbit/sec. It doesn't say whether that was up or down. That's on my AT&T Tilt.

650kbit/sec (1mb dl)
See attached file. My signal out at my place is a lot lower than I get elsewhere in the city. This is from Portland, OR...

sweet deal!
@ Shogunmark
is there a .cab for that IP Dashboard app that you can post? I would really like to start testing the upload speeds in the DFW area. At&t keeps saying any day now for HSUPA.
For those of you who want to test the upload speed of your Tilt, I would recommend using the Intenet Sharing app and tethering to a PC/Laptop. That way you can just use dslreports.com

I got 673kbit/sec
0.406s latency
5.158s d/l time
Phoenix/metro area - AZ
My Tilt shows the H icon 99% of time, have seen it drop to 3G and E in areas I have low signal strength.

the mobile speed test on dsl reports only does download, not upload... that is why i used IP Dashboard to monitor the connection and used total commander to FTP into my server and upload some large files..

The IP dashboard was a trial i found while trolling on handango.com ... it actually looks like a useful app..

Interesting. I have the H displayed on my phone all the time as well here in Minneapolis. I thought the Kaiser did not support HUSPA out of the box?
Will need to test upload speeds.

373.9kbps still falls within range of 3G/UMTS which is 384kbps.

HSDPA has an uplink of 384kbps.
Here in Singapore, I am using HSDPA, and the uplink can hit 370+kbps as well.
Officially, Kaiser is not supporting HSUPA, although the chip supports it.

good news
this is definitely good new as I live in metro detroit and in a very large 3G area. today the 20th we haven't changed over yet still showing 3G. on a side note I was ith tmobile and just came to att with my kaiser. with tmobile my results were 80-150 kbps with att 3G they are 500 kbps-850 kbps

I know this is a really old post, but I got about 3 Meg yesterday with speed test,
Around the forest park area. Hsdpa + in Stl now?

HSUPA on Diamond

I've seen I can activate the HSUPA on my Diamond, so I did it, but how can I know if I'm connected using HSDPA or HSUPA, is there an other icon? (like an H+ icon)

You'll get an H icon instead of 3G or G.

I've already got an H with HSDPA, but is it the same with HSUPA?

Not so sure i believe that myself...U was the old 3G icon that was used in early WM5 builds, but most people call it 3G, not UMTS so they changed it.
@d3us. you do realise that HSDPA and HSUPA are the same thing in different directions right? it's not an either or thing. they work together at the same time. HSDPA is the download link and HSUPA is the upload link.
So if you have enabled it, and your network supports it, and it is enabled on your account.....you should be using both HSDPA and HSUPA when you see the H icon, but for most of the time, and unless you are sending serious amounts of data, you'd never notice it just browsing, watching youtube and using messenger.
however, sending emails with huge attachments....then you might notice it.

I don't know if it's enabled on my account, that's why I was wondering, then the only way to know is to test my upload rate.

yeah you wont see any difference on the display.
your upload will just be alot faster

what network you on?
AFAIK, in the UK, the only network that has turned HSUPA on for their whole network is t-mobile. although as they share with 3, i wouldn't be surprised if they had it as well.
if your on any of the other UK networks, or in another country, i can't tell you i'm afraid.

3 in Denmark says that they don't support HSUPA but I still get a much higher upload when I enable it

it could well be that they are working to launch it and have just not announced it yet. Vodafone in the UK had HSDPA for a couple of months before they actually announced it to the public.....
Still, if you're getting the higher speeds, that's pretty sweet!

I'm using Orange in France, they should have deployed the HSUPA in some cities since January but I can't test now since I'm still on holidays using an EDGE connection^^
Orange claims HSUPA improve the ping, I hope it's true.

[Q] How to get "real" 3G speed?

Hi guys!
I just got my contract with mobile internet in it.
Each month, I get 1GB of data and it's awesome!
But I have some questions/problems with it.
When I connect to the 3G network, I sometimes have an E-connection.
It's pretty slow, but I found out this is some kind of 2G netwerk (called Edge).
Mostly I get an H-connection (HSPA(+)) I think and that speed is fine.
But sometimes it changes from a fraction of a second to a 3G-connection.
I think that is what I really need, but how can I "force" it to always go to 3G?
My carrier supports Dual carrier 3G, so that "should" double my 3G speed.
It would be awesome if you could help/inform me!

H (HSDPA or HSPA) is faster than 3G is faster than 2G.
I also get switching from 3G to H a lot at home were signal is not good.
