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???

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
Hi all. I was wondering whether anyone had any tricks to stop the PDA from using HSDPA unnecessarily. I find if I'm logged onto MSN all day, with just UTMS the battery would last probably 12 hours or so, but if I enable HSDPA it would clean out the battery in less than 5 hours.
MSN can't possibly require that much bandwidth. Is it possible to limit the phone from changing to HSDPA unless the bandwidth is actually required (i.e. when I connect my laptop to if for internet)
I use a dopod d810 in Australia with optus.
Thanks.

If you don't need 3G, switch the phone to GSM, which would use EDGE/GPRS, or use tools such as bandswitch etc. If you want to completely stopped data connecting by itself, try nodata.

Also, with some service provider, if the phone is connected to HSDPA, my incoming calls get sent to voicemail. If it is in normal 3G mode the call comes through. This has been a problem in many areas. As the last poster pointed out, Bandswitch can disable HSDPA so that 3G is the default mode. Since I don't have an unlimited data plan, I just change the band to GSM and use Edge unless I have to download big web pages or use the Video phone, then I switch to WCDMA mode.
Problem is, I use WCDMA all the time. I connect my laptop to the internet through my PDA. At these times the HSDPA is greatly valued. However, when I'm not and just want MSN messenger on my PDA, well, its a great battery drainer for no good reason.
At the moment I'm getting around this by turning HSDPA back on when I use the laptop and then off again when I don't so it just uses UTMS. However this is pretty annoying having to reset it every time.
Does bandswitching between GPRS and HSDPA require reset?
My carrier - 'MY MAXIS' is somewhat smart. They usually kick you out of HSDPA Network whenever you are not consuming large amount of bandwidth. The phone automatically switches to 3G , but then you are still connected. Then it will switch back to HSDPA whenever there is a sudden burst of data or so. Smart way of conserving HSDPA slots.
I don't think you can limit HSDPA bandwidth or so. Once its connected , its connected. It has nothing got to do with battery. Its just the power consumption. You have no choice but to disable the HSDPA module , so that it does not drain the battery a lot. Limiting bandwidth does not work. HSDPA/UMTS drains a lot of power.
Mine does that too... drop down from HSDPA to UTMS. But the difference between having HSDPA enabled and disabled in terms of battery life is like a third.
Its because if you enable it. It connects to HSDPA , hence it uses up more battery power. HSDPA loves to drain your battery life. This is why , you should switch to EDGE/GPRS whenever you are in mobile and switch it back to 3G whenever you wish to use it as a modem. You dont have any other choices ,mate !
Guys is it totally normal for your internet connection icon to continuously switch between 3G and H?? no matter whether I set it for WCDMA only or GSM / WCDMA auto..
I have noticed that when there is no current internet connection being made - the icon remains 3G, then when i connect to the internet it switches to H, but freezes up all the time. When I use my o2 sim on the same desire handset, the icon remains H and the speed is fast continuously without any pause or disruptions.
Any help would be much appreciated, also a copy of an APN for orange internet would be great so I could check it with mine.
Never noticed a H on mine. Only seen it go to 3G+
Mine goes between 3G and H all the time while im in my flat.
Not checked while im out.
Its probs a network thing, orange might not have a strong 3G+ network in your area so it keeps switching. I even seen mine on GPRS sometimes.
3G+ is HSDPA
What I'm trying to say is that my phone never displays a H just a 3G+. I have pretty good HSDPA coverage where I am
thanks for the replies - will keep testing my internet connection, still feel that o2 was faster but what the heck - the Desire was free so had to switch alliance!
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.
Hey, so I'm confused. I activated 3G on my phone but it is not showing "3G" but it shows a "H" icon instead. My friend told me that "H" is slower than "3G". I'm not sure if it's the fault with the phone or there is some settings I'm missing.
I've set the phone on GSM/WCDMA auto.
Please help!
H is HSDPA
Dont panic, H stands for HSDPA, which is faster 3G setting for the network. In order of speed you will see
G - basic GPRS - slowest data speeds
E - EDGE - Enhanced GPRS - A bit faster than G but not going to set your world on fire
3G - Faster connection
H - Fastest connection
Which one of these you get depends on the cell you are connected to, the quality of the connection and how many people are on the cell (sort of, I am no expert).
In summary, dont panic! Your phone is fine, you have a great network connection, but I am afraid you have a friend who is wrong. Break it to him gently.

I thought Edge was slower than GPRS?
My Vodafone Wildfire S shows 'E' at home (whereas my O2 Nokia phone shows "G" or "H" depending on the weather)
