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???

How to turn 3G off & only be on Edge??

I love 3g, but after one week on Edge only, and therefore with great battery life, I get off the plane in London and 4hrs later my battery is rub down.
I really do not need 3G, the speed difference for push email is irrelevant...
So any clues how to do this for those of us happy with good old gprs?

The search system is your friend... Check the main Hermes forum.

You can change the band the phone uses, its in phone>options>network(tab)
(i think)
just choose the appropriate band for GSM .

Wow. You get four hours? I'm lucky to get three in 3G mode with instant push enabled. I finally decided that I can live with getting email every 15 minutes and having my battery last 10 hours.

Search Google or the forums for "Hermes BandSwitch" -- click on the link for Comm Mgr Pro, then the link for BandSwitch (but check out Comm Mgr Pro, too).
BandSwitch is the easiest tool for switching between 3G and GSM. Some OS versions have a "Band" tab in the Phone Options screen, but most do not (a lot of operators don't want people screwing with that because they can charge more for 3G). If you have a Band tab, you can force it to GSM -- but only if you don't have an open data connection (it's kind of tricky to kill the connection and get into the options to change the settings -- and it won't let you change them while your radio is off).

What I did was to get the phone in an area where it gets no signal, then go into the phone, options, band, and take it off 3G or auto, and put it to GSM, should work.

Bandswitch
For me, Bandswitch is an absolute no-brainer app to install on your phone. Very quick and easy switching your phone from GMS to 3G to Auto Select .. all from the today screen. It is always the first app install after every re-flash or hard reset of my phone ... as I tend to keep my phone on GSM most of the time to save battery life, and only if I am in a 3G area and know I will need to make tons of calls do I switch back to 3G (so I can send/receive email and chat at the same time).
If you have not checked out this app (see link above) I highly recommend it.

Calls not getting through?

Hi,
I'm running my desire with rooted stock rom by oclock (called 3'oclock over at modaco).
Also running a2sd with richardtrip ocv14 kernel, and radio is 32.30.00.28U_4.05.00.11.
A lot of incoming calls are not getting through - sometimes they do, sometimes they don't. People are saying it goes to voicemail 2 or 3 times before it come through. I don't see missed calls on my phone when this happens.
This is with mobile internet set to off, so it isn't that.
Anyone else have this issue? And know how to fix?
Thanks.

Is it possible you could try flashing a differnet radio perhaps?

Are you on he boundary of your network's 3G coverage?
I find I often have to set 3G devices to 2G only in my house because the 3G coverage is marginal and the phones spend half their life jumping between HSPA and EDGE, and it often causes missed calls as you describe. Nothing exclusive to the Desire though, the only 3G device that never had a problem here on O2 was my old TyTN, and that was only because the radio on that was too rubbish to pick up a 3G signal at all here

It happens with my internet set to off though - haven't had mobile internet enabled all day just too see if it was this but it happens when the internet is off.

Your phone will still connect to 3G networks if the data is off. Try changing 'Network Mode' under 'Mobile Networks' to GSM only and see if that helps.

Will give it a go - hope not though cos i like using 3g for emails, surfing etc.
Will also try disabling the "enable always on mobile data" setting to see if that is doing it.
Thanks for the info.

I had exactly the same problem when I used the built in widget to turn OFF mobile data (I had a stock orange ROM in UK). I did this to save battery, but calls did exactly what you said. I now leave it on all the time (and actually battery has improved massively in my 4th week, dunno why, but I went 2 days without charge, and quite reasonable usage!)
Now I leave mobile ON all the time it works no problems, and haven't had the same problems since!

High battery usage when 3G enabled

Hello folks!
okay, the facts are: Im in very good 3g reception zone, MIUI 1.6.6 with default kernel, .08 radio, data on, wifi off.
Problem is poor battery life when 3G is enabled. Also, when using mobile data the H icon appears and data moves in and out, but sometimes the H icon just disappears and i get network error? I've tried numerous radio/kernel/rom combinations.
When i put airplanemode on, the battery consumption is constant 2mA (currentwidget). With 2G networks only, its 3-6mA. When 3G enabled, mostly the consumption is 20-40mA and sometimes like 10 times in day with minute interval of refreshing i get 8mA readigs. Any app to check if there is some syncing going on? I use only beautyful widgets weather widget, which updates itself hourly. And the normal contacts and calendar sync on. Fellow MIUI users have much lower consumption, a mate of mine gets 2-4mA when 3g enabled.

3g mobile network is one the battery killers. The h icon stands for hsdpa. This the fastest network but the network coverage is not that good yet (except for big cities). Switch network to 2g network (mobile off). If you really need mobile network, switch on 3g. Otherwise stay with 2g. There's imho no sense in using 3g without needing/using mobile network.

I tried using BatteryFu and APNdroid to get rid of my 3G while screen off. But that combination didnt work so well, sometimes it didnt disable my 3g and sometimes it wouldnt reconnect to 3G when unlocked. Any good programs to manage this?
I also wonder, I never cant download anything when 3G icon is appearing in statusbar. Its normally 3G but when I want to use the internet, it changes to H. Why cant I use the 3G network then? Im also having problems when the H goes to 3G the internet connection is lost. For example in market i get network error. The H wont stay there if there is no traffic for few secs.

Configured apn correctly? If you are not sure, do it again. Furthermore, you could try these settings for mobile network:
Uncheck data enabled and set network to 2g/gsm (depending on what you have). When you need mobile network, switch to "wcmda + gsm (automatically)" (name could be a litte different, translated it from germany) and check data enabled. I do it so and it's working fine.

Okay didnt understand very well what u ment by the last part of ur message
APN configured correctly? I have carrier default APN settings which have been working just fine for a year. If u ment APNdroid i didnt do much configuring with it. Gotta give it another try.

Last idea: flash latest radio.
No warranty for any damage.

3G only instead of HSDPA? is there a way?

is there a way to only allow UMTS on my Xperia Arc instead of HSDPA(WDCMA only in settings)? as UMTS is > 384kbit/s and HSDPA up to 7,2Mbit/s and HSDPA is draining my battery down to its limit and my phone's gettin hot.. sometimes I see a 3G symbol in the notif. bar but my connection then doesn't work.. I called the o2 service center and they told me that it's possible to get UMTS in my location.. really gettin on my nerves..-.-
thanks !

I doubt that's what's draining your battery. I know for sure some operators support FastDormancy which kicks the phone back down to 3G from HSPA when data isn't being used. Rogers in Canada does it. AT&T in the US does not support it though so my phone always sits on HSPA unless it's a really ghetto old tower.
You might want to see if modifying some of the flags in build.prop will disable HSPA (I know you can set EDGE class type for instance). You will just need root and a text editor and reboot after any modification.

and how to set umts only mate?

UMTS drains as much as HSDPA I guess or there isn't abig difference, at least for me.
I don't know how to get UMTS only...

so there's no way?! because while browsing over HSDPA network my phone will drain like 10% battery in just 10 minutes and thats inacceptable for me! over 3g on 2.3.3 where i had found a way to disable hsdpa it drained like 3/4% in 10 minutes..

Again that is *NOT* normal drain. Check your baseband version, I use -58 and hardly have any drain on HSPA or 3G (it's about the same), use EDGE if you want to save battery. (use latest flashtool to flash different baseband versions)
You're looking to modify build.prop or find some program that modifies it for you, you must have root to do this. I don't know the exact option in build.prop, but that's all I can help you with.

i have -58 baseband .. what's your battery life then when browsing like 10-15 mins?
