swtiching hsdpa and edge - 8525, TyTN, MDA Vario II, JasJam ROM Development

i noticed that sometimes my phone lags when swtiching to hsdpa ...for instance loading a attachment or on opera it would take a minute then swtich to the H and immediatly start downloading but it lags to swtich sometimes and sometimes even cuts out. Any way of fixing the lag or swtiching? So that i can have faster connect swtich times per say.

It could well be the network. Two things to be aware of:
- swapping between GSM/EDGE and UMTS+HSDPA requires the radio change modes. It's a bit like roaming to a whole different cell group.
- HSDPA is an extension to UMTS data, and is activated by the cell (if the client is capable) in very quick bursts, depending on the volume of traffic already queued for that client and on other users (I think I heard it was up to 10 users per channel). When things are busy you may not get any HSDPA at all. Or you may get it in short bursts that come and go quicker than the 'H' display is updated on your screen.

thats def true , ...but for some reason on my co workers phone he seems to connect quicker then me from my observations. Upon launching a program lets say mobi tv or any prgram requriing a higher speed connection where its avaible .My hangs for a minute then connects while his swtiches and connects almost isntantly. I was thinking if there are any mods regi edits persay to increase the swtiching code but guess thats not available.

Perhaps changing your network type from 'auto' to
'GSM 900+1800 , UMTS 2100'
or whichever your network uses. The device might be testing all frequencies when it is on auto??

thanks will try

try the new radio...143 that may help as well.

yea ima try 143 when i get home. I hate the delayed H. lol

HSDA <-> UMTS automated switching?

I've seen in my TyTN, WM6, radio 1.34 a (strange?) behaviour. I noticed with VODAFONE : I have a plain UMTS connection 3g icon and 3g data connection alive, used for push e-mail.
When I am in HSDPA area and data connection starts data transfer, I see a switch between 3G and H connection, then revert after 1-2 seconds ad the end of data transver back in UMTS mode.
Hypotesis:
1) Could be a simple WM6 LVSW edition bug
2) Could be a WM6 feature (HSDPA has well known problems in voice phone avaliability when active)
3) Could be a Vodafone Network feature, HSDPA onli when needed
4) 1.34 radio compatibility problem/feature?
5) ......
6) I am stupid and this is a well known fact
Question:
Any other wm6 user noticed same behaviour?
It has always worked like this, HSDPA is ON when you need it, not all the time.
thats part of the design, saving resources for the network.

This isn't working this way for all mobile phone providers in Italy, with TIM if you are in HSDPA area it will stay connected... and you're off-line if someone calls
May be we discovered why isn't enabled as DEFAULT setting and we need to enable using SetHSDPA.exe

Ditto in Australia. If im connected to GPRS, the icon is permanently showing HSDPA... unless of course i only have GSM coverage (very rare!!).
In Taipei, it works exactly as elivne says... H only when needed.
Cheers
FWIW, I didn't experience proper "throttling" in and out of HSDPA mode until I upgraded to WM6 and radio 1.38 (not sure which to thank for it). Prior to that whenever I was in H coverage, the radio would run almost exclusively in H mode. Talk about battery drain! Currently I can run for almost 2 days between charges (and that's with push mail).
How a particular combination performs for you must depend a lot on the carrier, your locale, etc. Took a lot of "trial and error" for me.
Yep, I'm on UK T-Mobile, and my icon only switches from "3G" to "H" when it's active.
As vp3G says, it noticably saves battery power from the old "permanent HSDPA" behaviour. Although I can't claim to get 2 days usage out of mine.
It is a network feature. If you are inactive on HSDPA for t sec the network will downswitch you to UMTS ( called R99 ). Only 10 users can use the HSDPA at the same time and there is an inactivity timer ( t=10 sec) try to manage the traffic by moving inactive users to R99 ( max speed 384 kbps)
Thank you for sharing your knowlege Austin Boy....
..."and that's the way it is"

Really only 10 simultaneous users? Seems like the odds of getting a timeslice when you need it would be virtually nil.
The 10 limitation can be increased by any operator by adding Channel elements (Radios) or more when adding another carrier ( frequency). Europe has more spectrum than the US and it is possible to get two carriers ( 2x5MHz) and use one for speech and the other for data. In the US we are sharing the spectrum between GSM and UMTS. AT&T will be migrating GSM to UMTS gradually and using the 850 band for UMTS before moving to LTE (4G)

I have a similar switching scenario.
Prior to flashing my Radio to 1.38.00.10 and ROM to Black 2.0 I tested my download speed at www.dslreports/mspeed and was please to see I got almost a 1Mb/sec rating.
However since the flashes I have re-tested and am now only getting 250-300 kb/sec. It may be the network, so I will try on a few separate occasions and different locations.
NB. I have enabled HSDPA in HTweaksC
I noticed during the test that the download bar jumps staright up immediately but then slows down quite a lot?

3 ITA is working same way.
Enabling HSDPA only when there is data transfer active.
Okay tried again on my commute home, and also when I got to my house.
Speed is looking good ! getting up above the 1mb/sec rate again.
Must have just been a busy cell/network
ok... i have a spv m3100 with black 3.0.1 wich is suposed to be HSDPA enabled... i have also enabled it in the tweaker.... today for the first time i have seen the icon H... in my area there is no HSDPA coverege... none... but i read today that untill the end of the year they are trying to cover it... and i was thinking that they are already making tests... i tested my speed at http://www.bandwidthplace.com/speedtest/ and i had a 145 kilobits per second speed... wich as far as i know it is similar to 3g... i disabled the HSDPA and tried a few times in 3g... the speed was 135 kb/s... to small the difference...
so... my question... what is the tweaker doing?... enableing HSDPA or just replacing the 3g icon with the H icon?
no one???
what is the tweaker doing?... enable HSDPA or just replacing the 3g icon with the H icon?

There MUST be a better way of switching 3G on and off!

The underlying problem here is that the 3G signal in my house is quite weak, but not so weak that it is undetectable. If I leave my TP2's band setting set to "Auto" then it keeps trying to switch into 3G mode, then dropping back to 2G, with a delay every time it does it. (Drains the battery too). So I'd like to be able to quickly switch between 2G and 3G mode. (Obviously I could just leave it set to 2G all the time, but this is a waste when I'm at work or in some other place which actually has a good 3G signal).
My current solution is that I've got a start menu shortcut pointing to CMBandSwitching.exe in the Windows folder. (This is the same program that is launched if you go to the TouchFLO "settings" page, then hit Communications/Phone/Band). In here I can change the Network setting between "Auto", "GSM" and "WCDMA" which has the effect of turning 3G on and off.
But... there are horrible side-effects. Switching in this way causes the current data connection to get messed up, so that nothing can actually use it to access the Internet. Web browsers stop working, and I can't receive email. I've tried switching the data connection off and back on in Communications Manager, and this works sometimes; but even when it does, it messes up my ActiveSync schedule settings. And usually I simply can't get the data connection to turn back on. More often than not, when I change the Band setting I end up having to hit the reset button to get everything functioning normally again.
There must surely be a way of turning 3G on and off without disrupting the data connection and ActiveSync settings and requiring a reboot? The phone itself can do this in "Auto" mode if I'm moving between areas of good 3G signal and zero 3G signal. Is there perhaps a way to tweak the behaviour of "Auto" mode so that it needs a higher 3G strength signal to switch to 3G? Or is there any way to convince the phone (while in Auto mode) that there isn't really a 3G signal present (even though there is really a weak signal) so that it switches to 2G in a side-effect-free fashion?

You might check into WMLonglife

I haven't tried it, but it may work for you. It functions more based on what you are doing with the phone as opposed to what bands are available.

3G / HSDPA Selection

recently got my HTC Hero I am with Optus (Australia) all the time when it says 3G at the top of the screen the connection is terrible (speed tests are slow etc) however if that says H i get more bars and super fast connection
if i use just 2G its just plan slowand not usable for VOIP etc
I am wondering is there a command i set to say only use H which i am guessing HSDPA?
Thank you
OzJames
The phone automatically uses the best connection available to it.
If it's not showing H, you're not within range of HSDPA service.
check on the market and download an apps called "any cut".after u install it open it and create a short cut for phone info by tapping on create a shortcut then choose activity then phone info by scrolling down to the options that says phone info.now go back to the short cut created called phone info and open it and scoll down to set preffered network type.the phone has a default settings to wcdma preffered.tap on the pull down menu and choose wcdma only and press on the back key twice to go to the home screen .this keeps your connection on 3g or H but will reduce in areas you cant get 3g or H.WHEN YOU GET THESE CONNECTION PROBLEMS CHANGE IT TO GSM ONLY.hope this helps

I don't understand, what is the purpose of doing this?
Like I said above, the phone will always use the best connection available (unless you set it otherwise in the options). Why set it to WCDMA only?
If you're in range of HSDPA service, the phone will use it.
Maybe I'm missing something, but this makes as much sense to me as asking how you can download more RAM to your computer

actually it would be like setting the computer up that it would only use a fast internet connection, and if it is slow not to use it at all. would be like connection fast -> page loads, connection slow -> page is not loaded at all.
hs(d/u)pa is an extension to the umts standard. if it is not available in the cell you are using there is nothing to do about it. if you have gsm with edge availabe that might even be faster than a bad 3g/umts connection, but that depends on many factors.
Works perfectly thank you
Its much more stable now

You're welcome
Heya, I'm also on Optus in Australia. The problem thatyou have described is actually really common with Optus users. Optus has way too many customers and have overloaded their system. A easy work around for a more stable connection is to change your APN from internet to yesinternet hope this helps.

[Q] 3g takes a long time to connect?

Ok, so my issue is different than everyone who is complaining about their 3g speed. My problem is that doing things that require a data connection, opening the facebook app for instance, see to take forever. I don't know why it does because once the 3g (which is actually usually already lit up) and/or upload/dowload arrows light up, it's pretty quick. It just seems like it's taking longer than it used to to actually connect to 3g. Opening web pages is the same thing, it will hang while it finds the 3g signal or whatever and then the progress bar will fly to the end and the page will be loaded. Like I said, fast connection (DFW area, TX) but takes awhile to actually connect. Anyone else experiencing this type of issue or know a workaround?
Bump......
As far as I know [don't quote me on this] but there is no work around. Some phones just take a little longer to actually connect. I toggle mine off/on all the time, and sometimes it takes a minute for it to "connect" but the speeds are not an issue. So I think you just have to be patient.

[Q] Data connection problems

Hi,
I have some data connection problems since the first day i bought my DHD.
The phone reception signal bar are always changing even when i am not moving at all.
It can generally move from H to 3G a few times, then go to E and then G, in a few seconds.
it always moves, my internet connection is very slow.
It's as if the radio was always trying to renegociate the method of communication (GPRS, 3G, etc) with the operator's antenna
When i am in a phone call, i got disconnected sometimes or the sound stop during a few seconds (the time the radio switch from 3G/H to E/G i guess)
When i disable WCDMA from the settings i get a quite stable sound during my phones calls (maybe because the phone no more tries to negociate). But for Internet... it's just slow.
I tried a few ROMs, and their respectives radio rom (the one with the IRL branded in the ROM) i sometimes thought it was better but always it's still too unuseable.
I tried my SIM card in an iphone 3GS and i am usually in Edge (sometimes 3G) but when its 3G i can surf quickly during hours (if i don't move). This is not the case with the DHD.
btw i am on the french carrier SFR
If any of u had any clues i would really appreciate your help.
Thanks you
what rom are you using and what radio and ril................... now what radio are you on now
OP already stated he tried numerous ROMS and their cooresponding radios. Sounds like the signal is that degraded that any radio/ril combination will not help.
Thanks for your replies.
As said i tried many ones with their respective recommanded radio.
I am actually trying Radio_12.62.60.27_26.13.04.19_M with Android Revolution HD 4G_6.1.1 with no sense script.
Are there tests i could do to identify if its a hardware problem (like standing in front of an antenna and running some special tool maybe)
Btw, i also tried :
-RCMix3D_Runny_v1.3 but does work with internet pass through (wich is really important since i can't use internet from my phone carrier...)
-niarkMIUI-3.9.1
-LeeDrOiD_HD_V4.0.0-SE-3.0-BETA with Radio_12.54.60.25_26.09.04.11_M2
-cm_ace_full-203 with my stock radio ROM
-virtuous_unity-v2.37.0 with i don't remember wich one...
P.S : i would be Glad to test any ROM / Radio combinaison you would suggest me.
Thanks by advance for your attention
if you tried all those roms and diffident radios seems like its more like a hardware or provider issue does it happen off different towers or maybe you can go to one of the stores and try the phone at the store with yours at the same time?
Thank for the advice indeed i need to try this.
Do you know what i need to revert back for the tech not to tell the waranty is over since i have flashed my phone ?
Does i need to reflash the recovery etc? is there some tutorial in this subject because if i go to the store with my custom rom i guess i won't get too much help :/
Don't even take out your phone, your going to say your just looking, don't show anyone your phone, they won't even know what to look for, just test your phone to the one at the store, make sure apn's match. But if you return your phone you'll need to ruu back to stock. You can search easy s-on

What happens if you manually select 3G only, or 2G only from the settings menu? Does it just lose signal, or stays strong?
Hi
If i select 3G only
I first get no reception (as if when switching from 2G to 3G the radio had to restart)
Then the 3G signal appear strong, decrease slowly in less than 30 seconds, and after all, it seems quite stable.
The bandwidth is good i am downloading fastly
(i am commenting in real time)
Still no deconnection.
I will try it during the whole day and tell how it is behaving.
umm during a few seconds, there were no indicator (no 3G or H), just 3 bars.
It then restarted in H with 1 bar (i am not moving at all)
What will happen if i have no 3G in my area ? I won't be able to receve a phone call ?
Thanks

If you force it to 3G only, and you move out of 3G area, then you should either get a no signal indicator, or if you have roaming enabled, you would get the roaming indicator. I'm curious now because as you said you aren't moving, and it's still changing. That shouldn't happen. Hmmm
