How to force HSDPA on Hermes? - 8525, TyTN, MDA Vario II, JasJam ROM Development

Hello,
we have full 3.5G network here. but for some reason it connects only with G all the time... how i can force it connect with HSDPA High speed?
thanks!

dont sounds like it

Go to phone, then settings, check if you see a Band tab there, if you do, check it and see if on the Network type, "GSM" is selected, if it is change it to Auto.

Get external antenna. i bought 1 from ebay...it really detect the HSDPA signal constantly.

Standing by the BTS Tower ???

nope..but if you are only getting G signal, then you have to check with your isp.

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???

How to make 3G band a prefered band?

On any of my phones including new Pro2 when I have auto set for band, it always connects to GSM instead of 3G band on my network. This seems to be network depended because when in roaming it always connects to 3G when available.
Simple fix would be to leave 3G band only and not auto, but where I live not whole area is covered with 3G signal so I would often be out of reach.
Is there a way to make 3G (where signal is available) preferred band regardless of network preference?
u should have play around with your device more often, or read a lot in the forum, its in the communication settings - phone - change band - choose WCDMA

I don't think you have read my question entirely
I know where to choose band, but I need it to be on AUTO since 3G signal doesn't cover all region where I live.
But at the same time i want it to connect to 3G first if there is 3G for my network. Currently when band is on AUTO and when I turn on the phone it connects to GSM by default rather than 3G.
In case of bad 3G coverage, The phone "Fall's" down in 2G mode by it self. We can't choose with one is prior to the other. It is an hadware (ie in the 3G ship) that is implemeted this choice, because 3G was promoted to respond to 2G saturation. In your case, this is due to a bad 3G covergage or bad 2G signal.
Hope it can help

I was afraid of something like this
Although I'm not sure this is in phone hardware, rather that preference is set by network. For example on my own mobile network even when I'm very close to 3G base station and signal is excellent, when I turn off the phone and turn it on it will choose GSM signal if phone is set to auto. This happens with every phone, not just HTC. And it will never connect to 3G again unless I set it manually in settings.
On other networks and when in roaming when I turn on the phone and have auto set it automatically connects to 3G, and when I loose 3G signal it connects to GSM but once 3G signal is available it automatically reconnects to 3G.
So I think this is actually set by network and not the phone.
I sometimes work at a place that has full edge signal, and 2 lines (stable and good reception) of 3g. All HTC phones always prefer EDGE, if band is set to auto.

oops sorry, my bad...
even in my room here the 3G signal is weak (1 bar), but the phone still prefers 3G (HSPA) and not EDGE, it turns to EDGE when i go to the bathroom , but when i got out, in a couple of minutes it turns back to 3G.

T-Mobile Connect to Internet on the GSM Network

I have been trying to get the data connection to work, when I am in a 2G coverage area, however I didn't have any luck.
3G works ok, but as soon as it goes on the GSM as apposed to WCDMA setting, none of the online options are available.
Do I have to set another access point on the phone to get data when I only have GSM (2G) coverage?
Hmmm, for some strange reason, yesterday while at work, I couldn't connect to T-mobile's 2G data network (GPRS)... Yesterday evening it shutdown by itself (empty battery) and after I restarted it, I have 2G data connection... very slow but it is there...
I wonder what may have been the problem. Any thoughts?

[Q] Control H/3G/E/G switchover threshold

Can anyone explain how the Arc (or is it generic to android) controls the switch between HSPDA / 3G / GSM etc?
I live right on the edge of a HSPDA / GSM reception area, so sitting in the same chair I'm often browsing using "H", and then slowed down to "G" - and vice-versa. Unfortunately, every time it switches it seems (to me) that there is a lag while it establishes a connection again.
Is their any way to configure the ARC to make it attempt to stay with "H" for a bit longer?
Go to Setting - Wireless & networks - Mobile Networks and change the Network Mode into WCDMA
Hope that help you!

Changing from Edge(E) to Hspda(H) doesnt drop the connection but the from H to E does. Also if the H signal is weak, it will change automatically to E. If you are in a building , parking etc you will have à weak H signal since your phone is covered by the walls

thank you both repliers.
It looks like there's no practical alternative to just letting the switch over happen as Sony have programmed it (or moving house).
You can try forcing to use GSM only or WCDMA only instead of GMS / WCDMA preferred.
The setting is under Wireless --> Mobile network settings --> Network Mode.
By forcing it to use WCDMA, the phone doesn't try to switch to GSM even when it has low signal. Good thing here is that, it doesn't try to switch between the two frequently hence battery might be saved and the bad thing about this is that, when you have a week signal, the phone tries to get better signal since it cannot switch to over to another frequency, hence the boosting uses more battery power.
Try it for yourself .

This is not only happening as programming by Sony but more likely by your operator. The operator defines the parameters that decide when they wish your mobile to switch from one network to the other, how weak they will allow the signal to become etc.
You can contact you operator, maybe they will log a case on it and investigate if the radio planning could be changed in your area.

[Q] 3G?

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)
