i fluctuate alot from edge to 3g, miami has a horrid tmobile footprint. regardless, while on 3g (umts), it takes a bit to switch to hsdpa. while im browsing i am usually greeted by this pause quit frequently no matter what rom im running. for refference, my sisters mytouch slide, daughters cliq and friends motorola charm prototype dont have this issue; they switch as often then me but much much faster. way more seemless in comparison.
if i were to jump on the speedtest app and wait till the H turns into a 3g, then hit the begin test button. the latency test wont run for a few seconds till that H appears; just an exaple.
anything i can do to speed up my 3g & H switching via the build.prop?
No idea, I don't think its possible. On ATT my phone always camps on hsdpa even when idle.

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 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
i'm having a problem with the band not switch when its low on signal. for example i will get the H and when it drops down to 1 or no bars it doesn't switch to E. also some times when the reception is around 2 or 1 and its on H, i would drop calls or can't call out at all. for some reason i've noticed that the reception issue happenes a lot and i would have to change the band to GSM and 850, 1900, then it would stay on E.
anyone has this problem or know a fix?

I was about to suggest you flash a different radio, but then I noticed that you're on AT&T. It's just your network being crap.
I believe the network sets the rules on handing your cellphone signal over to another tower. Only thing you can do is tell your phone to force EDGE or HSPA.
yea when ever i have no signal i have to force it and the best i can get is edge. but this wasn't an issue before? could it be a hardware issue?
Depends on carrier too. I have such issues sometimes.
But X1 also tries to keep 3G/HSDPA as much as possible...
YEAH I BEEN GETTING THE SAME PROBLEMS WITH MY XPERIA, I HATE IT BECAUSE IT IS LIKE IM BEING LIMITED OFF GOOD RECEPTION SIGNAL. SOMETIMES I CANT MAKE CALLS AT ALL. cOULD AT&T BE DOING THIS TO ALL CELLPHONES LIKE MY X1, SINCE THEY WANTED TO CHARGE ME 30 DOLLARS A MONTH FOR UNLIMITED INTERNET,SO I COULD GET 3G SPEED, SOMETHING I DIDNT HAVE BEFORE, BUT I STAYED WITH MY REGULAR INTERNET SPEED, AND NOW I EVEN GET FASTER INTERNET SPEED THAN MY BROTHERS AT&T HTC fUZE 3G PHONE.
Well just a FYI, but AT&Ts network isn't the great in San Franciso anyway.
Ive read several things on battery consumption and one the things is being in a bad service area. I am currently not in a bad service area (atleast I don't think) but my phone keeps swtiching from 3g to H and then H to 3g. Is this a problem if so what can I do to fix?
If I look at phone info whilst on 3G, I notice its switching between UMTS and HSPDA. Is the same thing? I also believe that battery life isn't as good as others report. Could this be why?
Your phone's connection idles at 3G and when you make a request, it switches to HSDPA and then retrieves information. It is normal to constantly see it switch between the two if you're using your data.
This is how I always understood it and am pretty confident this is what you are seeing.

I think the phone idles on 3g but when ya use data say in browser it'll kick up to H...
I think idling down to 3g saves power. But I don't like the 1 or 2 seconds at first when ya do data it has to switch to h taking the couple seconds. Now if ya instantly go to another page Its faster cause its on h. But if I wait lime 5 seconds it'll drop back to 3g so next page I go to it'll need to bump to h again...
Annoying but whatever
well I use juice defendor so when it snaps on when I take it out of sleep it snaps to 3g and then to H. So I'll pay closer attention to see when the phone takes it to 3g vs when it accesses the H.
My carrier had some little problems during the past weeks, aparently they were working on something. I sometimes, for short periods, did not have data connection or no servic at all. Now the problems are gone and a speedtest today showed that at my home, the download speed went from an average 1 Mbit to over 5 Mbit!
However, the H symbol won't go away anymore! It used to switch to 3g when not data was transferred. I assume that this will influence battery life.
Is there anything I should be worried?
From what I recall, H is faster than 3g, as long as your in a good signal area, the H will always be visable, it will only drop down to 3g if the area your in has no H signal... and if there is no 3g it will drop to a 2g signal... simples, having the H does not meen that data is being transfered!
I am aware of the different speed levels, what I experience now is that the H symbol stays all the time, whereas it used to change to 3g when idling even in areas with very good reception...

Wait, I don't get what you're saying. Let me clear it up:
Very good reception = H
Not so good reception = 3G
You want to see H (means HSDPA which is a a type of 3G data, but it's faster).

Okay, I'll try that too!
I live in an area with very good reception and therefore the phone used to switch from 3g to H whenever data was transfered and back . Now, however, it stays on H all the time and does not switch back to 3g when no traffic occurs.
It is just a change in the pattern my phone behaves so I wanted to get some info on that...
Hi, it's your phone doing what it should by seeking the best signal.
H refers to HSDPA which is based on UMTS (3G). Consider it a 'turbo' version of 3G. It's sometimes also referred to as 3G+ because it's faster then 3G but not really 4G technology. The tower in your area most likely got upgraded to HSDPA that's why you don't see the 3G icon anymore.

Not correct, he mentioned that his phone was using H on demand before, so the capability was there already.
The problem is that H mode uses more battery than 3G, which is why it normally only switches to H during data transfers instead of continously being on.
Possibly your provider made a change which forces your phone to stay in H mode. On hardcores homepage (see speedmod kernel thread) he describes a method to manually deactivate H mode if you want to play with it.
Hope that helps.

seems to be the explanation... Suddenly I have ~6 Mbit, so almost unsurprisingly there had to be a catch
as for disabling H, it would be permanently so not quite an option. I guess, I'll have to live with it but nevertheless I'll call customer support..
Hspa and 3g are actually different technologies, but can be used on the same site and freq. If you have noticed that your phone is nowdays all the time showing H ( hspa ) and not in 3g like before it means that your carrier has expanded their hspa features and capacity of the network on that area. Main difference between these two tech is of course the speed and how network resources are shared between the users. In 3g you have dedicated ones, but speed limited and in hspa you are sharing the resources between other ones under that cell area. hspa is good if you are near by the cell and there is not too many users from battery consumption point of aswell from througput point of view, 3g is better if you are on the cell edge due to dedicated resources reserved only for you. Main point is, battery consumption of your phone depends mainly how you use your phone ,what kind of applications you have and how often those are connecting/contacted by the network.
Browsing in 3g sucks!
