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?
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.
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?

i read that the icon will change to U

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.
I am right in the middle of orlando, HSPA+ Area, however, whenever i check the phone status, it says i am on UMTS.
Is there anything i need to enable or check for it to find the HSPA+?
wont say hspa+ doesn't support the 21Mbps speed but does work on the network (a lot of threads asking about this)
Will say UMTS until actual data is incoming or outgoing before it switches to HSDPA
mine only downloads at 1.5 mbps on speedtest.net
thanks for the info tho
I actually didn't notice at first(since 3g is patchy where I live) but since switching to the overcome rom my tab will connect to 3g but as soon as data transferring begins/resumes it will switch back to "H" which is thier high speed "Edge" network.
Baseband version: I9000UGJK3
Could this be the at&t modem that overcome provides?
Are there any other modems I could test out that might be better?
Thanks for your help.
found what i was looking for here
My toolbar still shows "H" during data transfers ("3G" otherwise) but the speeds seem fine, so I'm not sure what the issue is with that.
H is HSDPA which is faster 3G. http://en.wikipedia.org/wiki/HSDPA
Ok that makes more sense, thanks.
Speeds seem to be the same with the jm2 modem, anybody else done testing on the rogers network?
