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???

new radio causing 3g/hsdpa connection problems

I don't know if there are more of you having problems with 3g and hsdpa after flashing the new radio update.
My connection type only accepts gprs after the flash. When i dial *#*#INFO#*#* and choose information and tap the ping test, i can only see that gprs is connected.
With the older radio's i always had a hsdpa connection.
This is the radio i'm using: 32.41.00.32U_5.08.00.04
Roms are different roms with the same issue:
-Defrost 2.0a
-DJDroid v1.0r1
-Adams OpenDesire 1.5 and 1.6 prerelease.
All roms in combination with this radio are causing problems with my 3g connection.

Maybe if you specify the ROM and the Radio versions you are using, someone can help you....

dutch Hi / KPN... no difference at all.. 3g works fine, speedtest still showing 950kbps

Open desire 1.5, h3g data connection is HSDPA, with latest radio.

Well i only see the gprs icon, no 3g or hsdpa here. Speedtests give me 0.01mbit down and 0.02mbit upload speeds.

I just found 2 more simcards.
1 kpn
2 t-mobile
both the same thing, no more than 0.02 mbit up and down. . .
Maybe i have to try flashing a older radio back.

No problem with the radio (got 3.4 mbgit this morning), and I'm on dutch vodafone.

Ok, so maybe my phone is just broken....

Maybe vodafone 3G broadcast thingie (dunno) is broken in your area?

Yeah mine dropped to 2G All the time so I flash the Android 2.2 HTC sense Rom and pushed it to wcdma only. Works, I think it's an issue with the radio for T-Mobile UK customers
Sent from my HTC Desire using XDA App

No because he tried kpn and T-mobile as well.

I've always had 3G issues on mine regardless of radio so I'm putting it down to being orange. New radio for me seems better tho, I get H alot more so things work fine!
Maybe the flash didn't take...

I flashed Dj Droid 1.0 r1 today with new radio and ive not shown Hdspa since. I did a speed test and it showed 1.9 - 2Mb, which is good for where i am. I did the ping test and it came back saying Hdspa so i think with me its just the icon thats not changing.

2.2 unless patched will only display 3G icon for both 3G and H. I doubt HTC have put that patch in...

And found another vodafone card (vodafone dongle)
Lets try

I have the same problem with H only getting 3g signal, since I started using 32... radio. So its defiantly not network related.

Ok tested my vodafone dongle, and same issue (from laptop), so there must be something wrong with the vodafone network.
Pffieuw

I have same problem with last radio with ROM Six O'clock AM, Open Desire, AOSP, DjRoid and AOSPDesire_1.2.2.

It's a bit strange, normally when i am in the living room a always had 3g or hsdpa. Now i only have gprs until i go upstairs, when i'm at the top floor it shows me the hsdpa icon, and a speed test of +/- 1.5/2Mbit down and up.
So there changed something. Maybe Vodafone messed up their signal or there's something different with the new radio. . .

Slow HSDPA Data Connection, Froyo 2.2

When I was using Android 2.1 on HSDPA I could get 1.5mbps
But now since using Froyo 2.2 I can only ever get a max of 0.5mbps no matter where I am.
I'm on O2, could it be the APN settings are wrong?
I'm using a custom ROM
Official 2.2, with: busybox, old A2SD+, OpenVPN (TUN), EXT4 support, 802.11N
Click to expand...
Click to collapse
But I have tried a few Froyo custom ROMs all with the same problem
Does anyone know the reason why I can't get faster than 0.5mbps on 2.2 while on 2.1 I could get 1.5mbps?
Thanks

that sounds like a connection issue as in it connects to one network on Froyo and a different one on Eclair. Do you see any difference on the signal bar indicators?
do you know if the APN Settings are different between roms?

Signal bars seem the same, and using the same APN Settings, got them of the O2 website and input them manually.

Used a speed tester from the market

well using virgin media in a crappy signal area i got 355kbps down and 115kbps up on froyo on mobile net. are you sure you didn't set up you old rom to use your wifi and you have now flashed and are using only the 3g connection. Mine is 3 times faster too if i use the wifi!

With wifi I can get 8mbps so its no problem.
It's only HSDPA were i'm limited to 0.5mbps

Well having no exp of this or anything the only thing i can find is this, i hope it helps you.
all the best

I had the problem where I was receiving very slow speeds, but on 2.1 I was getting about 2mb dl.
What I did was check my build.prop in the /system/ folder and added the lines
ro.ril.hsxpa=2
ro.ril.gprsclass=12
this made my browsing speed go straigt back to normal. The market is also fast again. (if you are in the US, use 1 and 11 instead)
All you have to do is use notepad++ to edit the build.prop file with these lines. Add them near the lower half of the file. Then just
adb remount and
adb push (c:/whereever the build.prop is) /system
adb shell reboot
I am going to add these lines:
ro.media.enc.file.format = 3gp,mp4
ro.media.enc.vid.codec = m4v,h263
ro.media.enc.vid.h263.width = 176,352
ro.media.enc.vid.h263.height = 144,288
ro.media.enc.vid.h263.bps = 64000,800000
ro.media.enc.vid.h263.fps = 1,30
ro.media.enc.vid.m4v.width = 176,352
ro.media.enc.vid.m4v.height = 144,288
ro.media.enc.vid.m4v.bps = 64000,800000
ro.media.enc.vid.m4v.fps = 1,30
I suspect that I will be able to watch my camcorder files properly now. I haven't tried this yet but I will update with the result.
edit: All of my video recordings and other clips now work
Good luck

Thanks may give that a try.
Don't understand why this problem has occurred since I'm using the official HTC Rom

Also have the same issue on O2 since updating, slow speeds and eratic data connection. flips from H to G much more often.
Baseband : 32.43.00.32U_5.09.00.20
Not sure if this was the same version before the Update i was on a Stock O2 rom 2.1. but debranded and took the OTA update for 2.2
Facebook , Weather and Mail widget all need refresh clicking several times before they find updates (Maybe because of the slow connection??) .
Flash lags the phone almost to a halt. (not related to the radio) and most of the speed test sites use flash so i am not sure if this affects my results but the browsing time seems considerable slower even on non flash sites(flash disabled).
I am trying to avoid going back to a stock o2 rom, is it possible that this is somehow tweaked for their network ?
I am also reluctant to do the Bootloader downgrade which i think i would need to do to revert to the stock o2 rom ...is that correct ?
Many thanks in advance.

@jamesmcuk
I am assuming this would require root ? This would also mean downgrade of bootloader i think :-( it hurts

i'm on orange and a rooted non ota froyo rom
get alot of the G to H changing too but when H is lit it is very very fast
surfing is quicker on the network than on a wifi with 10meg speed
speed does seem erratic tho, maybe a reson of the recent orange 3g network downtime today and official orange confirmation of 3g problems

[Q] No 3g Download, only HSDPA or EDGE

Various apps (Facebook, Market, Head to Head & Internet Browser) will only download data when there is a connection to the HSDPA signal.
The 3G signal has shown as 3 or 4 bars but will consistently not download any data. Once the HSDPA signal is found, then the download starts. This can be frustrating as there isnt always a HSDPA signal.
i tried to insert another network provider sim card and it showed 3G and when i tried to launch for example browser it instantly changed to HSDPA icon and loaded pages so i didnt check anything... (i couldnt recreate a situation when only 3g was available, no HSDPA)
I currently am on DHD by baadnewz 1.7b but this also happend on Stock Desire Froyo.
any advices ?

HSDPA or High-Speed Downlink Packet Access is 3G..Actually enhanced 3G or 3.5G

It's difficult to comment. If you're rooted, try another custom rom with an updated radio.

i have the newest radio

If the "3G" signe appears in your phone, this means that it's trying to connect to your carrier's network. Once you're identified your can start to use data connection, then you get "H" "E" or another depending on the technology used by your carrier.
H goes for HSDPA, E Edge and so on...
So the lagg time is when your carrier tries to search whether you've got acces to a data plan or not.

[Q] Signal only shows 3G, no more H

Hi,
Over the last 24 hours my connection has only shown 3G as opposed to H in the statusbar. What's weird is when I check the connection in Settings > About Phone > Status it shows HSPA+:15, occasionally dropping down to HSDPA:8. I'm on the O2-UK network.
As I understand HSPA+ should come up in the statusbar as H. Is this correct? What's the problem? Also should I be getting HSPA+:21?
Running speedtest gives me: D: 2196 kbps, U: 1319 kbps. D varies by +/-600kbps
I'm running 4.2 Kalo v5.0 on Franco r318. Radio is XXLH1. I've also added kevdliu's quick settings mod.
Thanks guys

Although not directly comparable my friend, also in London but about 10 miles away and running on giffgaff (which piggybacks the O2 network), is getting D: 3337kbps, U: 2109 kbps. Afaik giffgaff speeds should be lower than O2 pay monthly but this might be due to the area etc.
My first thought is that my statusbar is just buggy but I can't shake the thought that there's something wrong with my phone's signal/radio. Should I be getting faster speeds (HSPA+:21 or higher)?

+1 on this issue. Had HSDPA on 4.1.x, then suddenly 3G on 4.2.
But I think you're getting the right speeds. At least I know I am.

Same here in Canada on Telus network.
Status bar never shows "h" anymore.
When downloading something network type will switch to HSDPA+:15 but otherwise is always at HSDPA:8
I think that's the way its supposed to work to save battery but i dont know why the signal bar only shows 3g now...
