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....

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???

cingular 3g problem

i bet that this has been answered thousands of times and i probably haven't just found the thread but i have a cingular 8525 and i upgraded to wm6 lvsw it great but i cant seem to get the 3g network back and all i get is that big E for edge and i want to get back on the 3g network i have applied all the cingular setting cabs in the wiki but if any of you guys can help id appreciate it and sorry if this isn't in the right place thanx guys

The settings for 3g are the same as the settings for gprs/edge.
Maybe you need to go into settings->phone->band and make sure your network type is auto or (wcdma) and your GSM/UTMS band is set at GSM(1900+850)=UTMS(1900+850)....

I ran into the same problem numerous times. there also seems to be a few issues with the data connection. I don't know if it is the ROM or radio but it is pretty anoying.
Another issue I have been experiencing is the weird behavior I get sometimes when I receive a phone call. twice it frooze on me and I ended up missing an important call. I am thinking about going back to some of the other roms.

I have the same problem running the Black 3.1 and end up with "E" EDGE" connection most of the time instead of "3G" that I got with the Black 2.5 and the Custals new Rom. Your phone or device will connect with the fastest technology that it supports and that the network supports in that area. If you have an HSDPA phone or PDA, you will automatically get HSDPA (or UMTS) or fall back to EDGE (or GPRS) if the signal or network can support.
3G and 2.5G are interchangeable
2.5G = GPRS and EDGE
3G = UMTS and HSDPA

swtiching hsdpa and edge

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

Icon/Notifcation Problem

Hello all, I am bit new to the 8525 game (tytn) just bought it actually. I am starting to dable here and there, I have tried schapps 4.22 and moved to K's rom. Now, I did a base install of the HTC wm6 rom (radio is 1.48), ran the sim/cid unlock, hardsplv7, and installed K's rom. Now I actived that HSPDA switch, but I never see it change. I tried installing schapps 2g dialer to see if it would be any different and nope it persists on the 3g icon. This did not happen before when I first tried Schapps 4.22 full (only thing different was not installing hardspl). Anyone have any insight on this?

Update your radio to 1.54. Also, the icon will change from H, 3G, E, and G depending on your speed. Enabling Hsdpa doesn't automatically change the icon to H. It only shows H if you are getting HSDPA speed. If you are getting 3G still after enabling hsdpa, perhaps the signal is not strong enough to reach hsdpa speed.

let me guess:
H = HSDPA
3G = Third Generation
E = Edge
G = GSM
am i right?

yea those are correct, as far as signal. I've tried it in many different locations, it never switches.

Save for G = GPRS. GSM is indicated by the bars.

you can reflash with schap's rom and see if the icon appears. I don't have the luxury to use hsdpa here so I've never tried it and I've never heard anybody saind anything about that in my thread.

the 1.54 did the job.

my guess is that your radio got downgraded when you flashed the other rom.

what is with the misinformation in this thread?
3G IS HSPDA, or more technically HSPDA IS 3G.
The only thing an H icon represents is data transferring on 3G. If there is no data being moved and you have a 3G signal, you will see the 3G icon. If there is data being moved and you have a 3G signal, you will see the H icon.

Data never works when showing "3G"

My phone doesn't seem to have any data connection when "3G" shows, but works amazingly on "H" and just about bareable on "G". "E" shows occaisionally and doesn't seem to have internet access either.
When loading a web page for example, if it starts on "H" it will start loading, if it switches over to "3G" halfway through loading, it will hang and nothing will continue until it switches back to "H".
I've found many, many threads on similar issues on here, but wondering if anyone experiences this exact same problem.
I'm thinking my telco's (Vodafone Australia) default APN settings that are pushed to the phone arn't very compatible with android.

same for me. if it is 3g it waits till get h then loads... mine is t mob uk, probably because of them...

And what about E (edge)?

mine is on only wdcma mode...

3g H
hi, my carrier is orange, luxembourg,
had extreme difficulties with 3g, h and e,
but after 2.2 ota everything is great.

same problem for me... it doesn't transfer any data on 3g... all is fine on h,e, and g
