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!!

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?
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
The 3G Icon has never displayed on my tilt. I live an area that supposedly has great 3G coverage.
It's quite annoying since all the screenshots I've seen of the Tilt are always displaying the icon.
I get the E, H, and very rarely the G icons but I've never seen the 3G icon.
Any ideas?
Well,
The H is for HSDPA, which is higher speed than what the 3G denotes....so I'd say that you are doing just fine.
Yeah, I do get he H quite a bit.
But I just find it strange that I've never seen the 3G Icon.
Maybe because I am not using the stock AT&T ROM. I'm using Q-Mobile 1.2
Is the 3G icon specific to the Stock AT&T Rom?
Yea, is there a cab that changes the icon to 3G?
I have the stock AT&T ROM in my Tilt. When it goes online, the 3G lights up first, then, when I am lucky, an H replaces it. The difference in speed is noticable when the H is on. You can use Kaiser Tweaks to enable HSDPA on the Tilt - stock, it only allows access to the slower 3G speeds.
Why would you want to disable the higher speed transfer?
The H icon you are seeing is actually a good thing as it means that AT&T now has full HSDPA coverage in your area. In my case, the first three months that I had my Tilt, the 3G icon showed when idle and the H icon showed when I was downloading data. One day, out of nowhere, the 3G icon disappeared and has been replaced by the H icon for good. I have now noticed two things that are different now that the H shows all the time.
1. I can now make a call without the data connection being disconnected.
2. My download speeds shot through the roof! When the 3G icon was there, I had speeds of about 550kbps. Now I get speeds of 1000kbps!
Dont worry, I too panicked and tried to fix the missing icon, but even after a hard reset didn't remedy the situation, then I knew it was something tower-based.
H is good. It's amazing. It's like cable internet in your pocket. (OK...but close...)

On a Tilt you can also go to Start / Programs / File Explorer / My Device / Windows / HSDPASwitch to enable and disable HSDPA. You can even create a shortcut to it and put it in your programs folder or start menu.
There's a lot of hidden goodies in the windows folder. Everyone should just browse through there and see if they find anything interesting. (Field Test is there too!)

No I mean just the icon, I don't want the H icon. I just want 3G. For some reason when ever I look at it it makes me feel like its a slow speed.

HSDPA is the fastest type of 3G available. Think of the H as the strongest possible connection.
In my city, I get 3G icon in the phone mode while not connected to the internet. While I was in Las Vegas, I get the H icon in the phone mode while not connected to the internet. It's strange but it's true. I've always thought the H icon is for data only but apparently H is also in phone mode too. I get the H icon in my city only when I'm usnig the AT&T's data and only while there's data session. When data is idle, it change back to 3G. But when I was in vegas, it never changed to 3G. It always displays H.

Before, indicator (G, E, 3G or H) show 3G and then phone make data call its shows H, but form today morning its stay H all the time
Any ideas?

Thats correct. My icon is also on H now all time. (PHL)
Philly area
I live in this metro area myself. The H icon does mean HSDPA however you can set this off using Kaisertweak. Once you're phone resets it should go back to 3G icon. If you want to me more technical with switching bands, you can use the newer comm manager and advaned config to add a 3G on/off button for toggling between edge and 3G. Remember HSDPA is a faster form of 3G, the 3G icon just refers to the slower form of it which once was a default until the recent upgrade.
very wierd...i always have 3G turned off....so I'm always on EDGE...tonight i opened up the comm manager and turned 3G back on...now i have H at all times....
But! with the H or the 3G i get less signal strenght....on Edge i get full everywhere

EDGE data coverage is from the GSM side of the network.
The H is from the 3G side of the network. The technologies are different, and so is the coverage. The footprints are not exactly the same.
However, with 3G... you only need 1-2 bar to be able to place/receive phone calls. Voice quality should be reasonable.
Just an FYI.
oh...so what should i leave?
the EDGE or the H?
i dont have a data plan if that even matters
How do they fair up for battery life?
I hear that 3G uses less battery than EDGE does...is this true?
What about HSDPA?
Um, no you've got that backwards. Edge uses MUCH less battery than 3G and way less than HSDPA.
If you don't use data, stick with Edge.
but the H icon makes me feel special

PDX area just switched over to HSDPA a few days ago - I'm so happy!
To make things even better, then guy in the store dropped my plan down to $30 a month (no txt messages) which was unavailable when I first bought the phone! Sweet Deal!
I did the kaisertweak to enable the H network or whatever (yes i don't understand it)
the network still says E or 3G . It said that all the time, for the last few days.
Then I was messing around trying to get this gps to work in google maps and I noticed it switched to H. but now it's back to 3G. is this all normal?
Ive noticed that too..
no idea what it means
what operator are you with in what country
check with them to see if you have hsdpa reception my hsdpa is enabled but since i dont have coverage i stay at 3g
hsdpa is a better version of 3g
its often called 3.5g 3g+ or mobile broadband so basically all the twaek is is to let your phone get the faster connection but only if your operator has the signal to do so
The H icon (HSDPA) is a step up from 3G it allows anything up to 7.2Mbs transfer but the HTC instead of contantly allowing this to be active thus creating massive battery drain only allows it when a data connection is active and data is being transferred any other time and you will only get G, E or 3G
3g alows ypou to have video conferences but H mean HSPD fast internet 3,6Mbit or 7.2Mbit depands that the difference i belive.
exactly just because you enable it doesnt mean you can recive it
I turned hsdpa with kaiser tweak also. I noticed it will only connect to hsdpa when transferring data (IE, emails, weather, ect.). Otherwise it will go back to 3G when on the today screen, or offline tasks. I guess its to conserve power?
Maybe thats what your seeing?
ok thanks, looks to be normal =]
