Keeping gprs/Edge active while you're on the phone - Networking

I have a Cingular 8125, and I'm using IM+ by ShapeServices.com. Was wondering if it's possible to keep the gprs connection active while I'm on the phone, or if there's only enough bandwidth for one or the other.

Can't be done. That can only be achieved using a Class A device. Class A devices don't even exist yet, as far as I know.
You either use GPRS/EDGE or you use voice. One at a time.

stupid class b device! LOL
thx for the feedback anyway

class A devices are all over the place now. mAlthough it tends to be only 3g phones at the moment.
Hopefully, the next 3g WM5 device will be class A, but i doubt it!

Call and Receive E-mail at the Same Time..??

I currently have an O2 XDA2s and am considering switching to the Wizard for the larger, more legible keyboard (who at O2 came up with the idea of pairing a blue backlight with turquoise special characters on the xda2s keyboard!!?), a higher resolution camera and what I hope will be (based on reading the Magician Forum) a better overall integration of features.
I use my device for business and so receive a lot of "real time" e-mail via our GoodLink service and do a fair amount of teleconferencing.
One of the limitations of the current collection of devices is that when yu are on the phone, no e-mails are received. As soon as you hang up, they all start to download/ be pushed to the device.
In reading about the dula processor architecture on the Wizard, it raised the question of whether the Wizard would be capable in theroy, or better yet practice! :wink: of receiving and displaying an e-mail while you are on the phone..??
Does anyone know or care to offer an opinion?
Regards
Chris
If youre receiving the emails by GSM/ GPRS then while you are in a phonecall you wont be able to receive them... however, maybe if you can use WiFi simultaneously with GSM you might be able to.
Hi ShALLaX
Many thanks. That's the same as the Blue Angel then... Interesting idea about the wi fi connection though... I will try that and see if it works on my xda 2s. Will let you know.
Wonder if the Universal will have the capability, as it appears its using a separate 3G modum for data..?
Regards
chris
Well some good news here is that you can indeed send and receive e-mails via wi fi at the same time as being on the phone.
So the moral of the story is.... always do your teleconferences from Starbucks¡
Heheh, good job!
As far as I know...the GPRS class in both BlueAngel and Wizard supports calls and GPRS activity at the same time. But the GSM network you are connected to must allow it. None of the networks here in Norway allows it
Ø
Hi t0flus
Thats very interesting... that must be why it does not work in the us either.... I will be interesting to see if the wizard behaves any differently. Will hopefully be able to try it out in a couple of weeks
Regards
chris
I can confirm that the Jam does this , as my TomTom GPS accepts calls while updating Traffic info over GPRS. Hope this helps.

I think you experiencing a delayed reaction. The data must have been recieved before the call began, but was only rendered on the screen after the call was started.
The ability to receive data and use voice at the same time is dependent on the type of modem. In order to do it the device must have a class "A" modem. PPC Phone Edition devices use class"B" modems. Class "B" only allows one at a time, either voice or data.
Dave
Not sure, all I know is as part of the setup with TomTom 700 it asks you if you want to recieve calls and access Internet at the same time. I chose this option and it seems to work. Well I've had no problems yet.

Here is a link that explains it. Scroll down till you see the explanation for class B. All Pocket PC Phone Edition devices that I know of use class B modems.

No GSM Network in the world allows simultaneous GSM call and GPRS - the technology can't do it (at least what's in operation can't).
In UMTS land, you typically get allocated 128kbps of bandwidth... during a call, 64kbps is reserved for voice/video, and 64 is available for data download.
So to answer your question - yes in UMTS land, yes with wifi as the data bearer
Thanks Southern Man! Where have you been?... and where is that new O2 UK !.40 ROM with the Blackberry client for the xda2s? :wink:

Universal with HSDPA?

Thinking on getting an MDA pro with T-Mobile in the UK with the walk n web unlimited internet, only catch is that it is UMTS. With the news that T-Mobile are upgrading the network to HSDPA wondering if there is a HSDPA universal due to be released anytime soon? If not, the other option is to wait for the Hermes in June.
The UMTS Notebook Cards can be upgrade to HSDPA with a new firmware, but i think the Universal haven't the necesary hardware for that. Wait for the Hermes...
Forgive the ignorance but what exactly is HSDPA?

Thanks lutzs, only prob I have with the hermes is the small screen 320x240.. the small screen is big minus Im not looking to use it as a phone, but more for PDA and internet access... also plan to use it as a gateway (over bluetooth) for my mac to get to the net... thought about the pcmcia card, but need to lug laptop everywhere for that, whereas the pda itself is much more portable...
i think the tradeoff of speed over the usablility (screen, keyboard etc) might just be worth it for my needs...
another question, has anyone used t-mobile uk's web n walk with the above scenario of using it as a bridge for internet access for a laptop? the small print says that you can't do that blah blah... but don't see how that can tell if you're browsing through the pda or your computer? http is http...?
haven't used tmobile, but the universal can be used as a modem. Via bluetooth should be fine (*99# etc.)
HSDPA is not part of the universal chipset. however I wouldn't get too excited. Mobile cells have to share bandwidth so the chance of anything fast is unlikely. Put it this way, by the time we actually get 384k sustained on any 3G network, that should be fine for web & email & online games.
I had an o2 xda mini s. but i gave it back. 320x240 is very limtied, adding that to the dismal 196 mhz omap was not usable.

What do you think so far

I love my TyTn no problems at all, very fast and HSPDA rocks, so does the scroll wheel one handed operation is now a reality
Chris
So far, I'm very impressed with the speed.
The one-handed aspects (like the scroll wheel) are tremendous.
HSPDA definitely rocks. Depending on where/when I try, I've seen download speeds between 600kbs and 1.2mbs. Not too shabby!
I'm having issues with "Internet passthrough" access while connected to ActiveSync, but otherwise, problem-free!

OK.
Then please tell me the following:
(a) How do you conclude you are on HSDPA ? I assume you are deducing that from the downlink speed you experience, ain't ya ? Acc. to my experience you can conclude you are on HSDPA if you get good continuous rates of well beyond 400kbit/s.
(b) Then which software (PDA or PC-based) are you using for checking the downlink data rate ?
(c) Can you disclose in which town in the US you are residing ? Afaik Cingular has only recently rolled out HSDPA. So I'd assume you live either in or slightly outside a larger town to have access to HSDPA.
Something else - regarding the scroll wheel:
I agree, this could be a great helper for a one-hand operation.
Unfortunately I think it could work more intuitively and is in some aspects even lacking functionality where functiuonality would really be needed.
E.g. when surfing in the internet.
You can invoke the IE using the scroll wheel; but how the hell can you then access your IE Bookmarks ??? :-(
As a resolution HTC could have programmed the first up-scrolling movement with the wheel after invoking the IE as a trigger for starting the Bookmarks. What do you think ?
Also when scrolling thru the Bookmarks the wheel opens every sub-folder when moving on it, thus it needs really very long for selecting any specific bookmark if you have accumulated a big collection.
Why is the wheel opening a sub-folder when only a click at a folder should open it ? A little bit of a bug. What do you think ?
My opinion is:
The wheel definitely is a step forward, but still needs development.
Regarding HSDPA: There is no way of finding out if the device is really on HSDPA (same applies to EDGE btw) other than by judging on the downlink data rate experienced (which tool ?).
As my operator offers HSDPA here (and I get tremendous downlink rates using one of these Vodafone Mobile Connect Cards) I somewhat doubt that the TyTN already offers HSDPA capability as the speeds I experience (both when using as a surf machine as well as a modem) are good UMTS speed but really not HSDPA !
Which brings me back to my mantra:
"Guys, we need a generic way for distinguishing between HSDPA/UMTS and EDGE/GPRS, like the registry tweak for the predecessor models !!!"
Oh the TyTN does indeed do HSDPA. I live in a Cingular HSDPA launch city, namely Salt Lake City.
I've teathered it to my laptop and have acheived speeds of over 860/kbit download via dslreports.com. I can also acheive nice low latency between 200-300ms.
I have seen the device drop to GSM/EDGE mode when I'm in a bad area and the speed immediately drops to 100kbit or less.
At least in Salt Lake City, wherever the phone shows a U icon, I'm getting increadible speeds.
I ran the dslreports mobile test on the device and it gets the same speeds as when teathered to the laptop. Also I ran dslreports speed test through my wireless internet connection at home which is teathered to an 8mbit cable modem account. On this connection the TyTN tops out at being able to measure around 1500/kbit through pocket IE, so the average 600-800kbit over HSDPA must be pretty accurate. Very rarely am I seeing less than 600kbit download.
-James
For Salt Lake City let me clarify. When I have a U, it's always getting HSDPA speeds, when it shows a G, I'm always getting EDGE or less speeds.
Around here I assume everywhere we have UTMS, we have HSDPA enabled, this is how cingular did it. This is the same for GSM, wherever Cingular has GPRS, they have EDGE so whenever I see a G icon, I'm getting edge speeds.... now wether it truely is EDGE, or regular GPRS I don't care, in fact who cares, it's so slow compared to HSDPA the difference is not important to me. As long as I got the U, I know I'm getting HSDPA.
I guess for networks in Europe that deployed UMTS before HSDPA this doesn't help you determine if you are getting HSDPA or not. However from what I understand, if the network has HSDPA, and your phone is capable of it, then you just automatically get it. You are not selectively being denied HSDPA or anything, it's more spectrally effecient for the operator to let you use it if it's available. It would simply decrease their cell capacity to somehow deny you use of it.
A good example is on Cingular, I have a data package, I popped my 3G sim into my phone, and the same data login settings still work, only it's a hell of a lot faster.
Can you determine if HSDPA is indeed availabel on the towers in your area?
-James
In Europe, as the operators started off with UMTS a couple of years ago, HSDPA is definitely something of an "upgrade", thus not seamlessly switched on.
Would suppose its to a large extent a question of licensing and licenses have a better payoff where the services offered thru them are actually taken up by the customers.
This is surely the reason why there is generally not (yet) HSDPA available in every cell which is offering UMTS. (Agreed there are other reasons for that as well, but this one is a very important reason.)
As I live in the capital of my country and the HSDPA coverage is very good here (also other populated places in the country are well covered with HSDPA already) I can get high data rates using one of these high-speed PCMCIA data cards for the PC (e.g. the Vodafone Mobile Connect Card).
In the same cells I get a much lower data rate when surfing with the TyTN.
This made me wonder whether the TyTN at all already supports HSDPA.
My only complaint so far is the A2DP. The headsets I have tried with it do not have great connection. In that I mean that it connects fine, but there is always these constant pauses within a song (i.e., when I'm listening to a song) that drives me nuts. My M600 from Sony Ericsson does not do this as the connection is problem free. Also, the whole phone seems to slow down when I'm using the bluetooth headset to listen to music.
That's it so far.

There are some registry hacks that help the AD2P performance
jmacdonald801,
Thanks for the post. I'm in Salt Lake City too using heavily hacked Wizard on T-mobile's network. I love the wizard but have been missiing the Evdo speeds of Verizon but I need a world phone for my business.
Where'd you order your TyTN from and what is your cingular plan costing you?
Thanks again.

I created a big stink on ho-fo because my TyTN was defective and I tried to return it after the 7 day policy of the online reseller.
Listen, I would be neglectful if I didn't tell you you are taking a big risk by purchasing this device, regardless of where you buy it. As you may have read here, this device has a serious quality control issue. Even replacement units are not always bug free.
That being said here are some things you really need to consider when purchasing this phone.
HTC is not obligated to repair your phone outside of the countries where it is meant to be sold. The United States is not on this list. I read the warenty documentation carefully. This doesn't mean they won't repair it, it just means they can tell you to bug off at their leisure. You could end up shipping this thing back to Europe and who knows if you will ever see it again.
The phone will cost between $700 to $800. Now that's a lot given that HTC isn't obligated to fix it, and the retailers you will encounter online will only offer a 7 day "exchange" policy only. Not only that, this policy may not be made clear to you during the checkout procedure.
Now assuming the HTC didn't have the number of issues that have been reported here, I could recommend someone to buy it from, but I certainly don't want you to take the chance of ending up with a defunct device with no warranty and basically up **** creek without a paddle.
While the device is "fun" and "neat" I doubt it's really going to provide you with any more functionality than your current device.
Now onto some positive information...
I have an older $19.99 media net package. It has unlimited data. I get 1200 text messages and 200 MMS messages. This package will work fine on the TyTN regardless of what anyone at Cingular will tell you.
What they won't tell you is what the physical difference between MediaNet and the PDA/Laptop plan are.
Firstly, there is not speed difference, if you have HSDPA, then you get the speed, period.
Secondly, Media.Net uses a fake IP address, similar to what happens when you have a router at home. the PDA Plan will give you a real internet IP address that people can connect to from the internet. The operational difference is simple, Media.Net will not allow you to use Corporate VPN, I have tried. Skype, and about every other application will work fine on Media.Net.
I don't know why Cingular makes such a big Stink about this, I use Cingular video MobiTV and you can literally eat hundreds of megabytes of data using Cingular's very own Media.Net applications. It's really just a scam to get you to buy a more expensive plan, which is fine if you need VPN.
As for me, I'm in the process of returning my TyTN and I'll stick with the LG CU500. It's an excellent phone. I think I'll find a PDA with 640x480 and bluetooth and just get the internet via the phone over bluetooth. This way I only need to carry the bigger device around when I need it and the phone just works without any complication.
If you can accept all the complications and risks involved in buying an imported phone for that amount of money, then I can recommend a good person, however I didn't fair so well.
Wait for the Cingular version.
-James
James,
Thank you for the candid response. I was going to wait anyway. I get a new phone every 6 month now and I've only had the Wizard for 4. In browsing this forum, I see there's quite a few bug which need fixing. Your advice to wait a while is much appreciated.
My wizard is working so well that the only thing I miss is the 3G internet. T-Mobiles 2.5 G ain't bad for anything except streaming video.
You've made me very eager to try the device on the Cingular network.
Thanks again.
@rkorzuch
Thanks for the A2DP performance tip from the Wiki, works for me with ITech S35 - improved audio quality.

out of curiosity, do you ever see an "E" when connected to edge networks? or does the TyTn handle "G" as either gprs or edge and "U" for UMTS?
edit: nvm...read the FAQ. that kinda sucks...i hope someone can figure out how to enable the "E" icon for the hermes.
Hi
I live in Austria - I am on T-Mobile and I just gut 664kbit/s using http://performance.chello.at:81/
So that seems to be HSDPA

@mdajax:
No "E" for edge on the TyTN unfortunately. The known reghacks don't work. Some are playing with the bitmaps that make up this display but so far I haven't heard of any success stories.

just measured 1100Kbps, so much for my monthly data allowance at this rate it'll last approximately 300 seconds ......

HTC TyTN

I am considering buying this device in USA and go with the 3G network offered by Cingular. Anyone her ein the US thta has experimented this phone already and verified that the 3G is working and that the video calls are working too? Please let me know... Thank you, Paul.
Hi. You really should search before asking questions (this one has been answered many times)...
Yes, there's 3G available in many metropolitan areas with Cingular, and it works great (depends where you live though).
No, you can't use VideoCalling (Cingular doesn't support it).
G3 and video calls...
Sorry! However I researched using "3G and video calls usa" in several combinations but did not get any info. HOwever, I just got the Loox t830 and I am sending it back because the UMST doesnt work here in usa. but at this point I understand that any phone would not work. And anyway the customer services of Cingular told me that it would, but of course I don't believe them.... Thank you for your answer!!
830 is UMTS 2100 only .. so it's 3G wont work in the US .. Same prob with SE P990i ..
For the US, you need UMTS 850/1900 atleast ..
3G works fine on it, but you'll run into the problem that the connection speed is almost TOO fast for the browser. The high speed is really only good for stuff like Skype or other VOIP app's. Downloads are of course fast, but your day to day browsing doesn't speed up much, no matter which browser you try.

This is very interesting. I have a question for you and all the other friends: did you try to check the speed of the connection via a computer? I mean, you can go in internet via the phone, from a laptop via the phone, or you can stick the sim card in a PC Card (I have a Sony Ericsson GC83) and go in internet. If you did so, what speed did you have, or could you get? Thank you, Paul.

Phone as external modem for Athena?

I have just got the viewty phone but obviously browsing on an Athena is a better experience, is it possible to use the viewty (other phone) as a modem for the Athena without their being a sim card in the Athena.
I know it works on WIFI but can another phone do this
Yes provided you have the right data package on the viewity you can connect via bluetooth and use the viewity as a modem, but there are a couple of things to consider.
1) is the viewity HSDPA !! is it even 3G if not expect SLOWWW speeds
2) if your on T-mobile having the £7.50 per month web and walk is not good enough, you have to pay the extra £5 to get web n walk pro! this is because the LG acts as a dial up modem not an internet sharing device.

bt DUN is more than fast enough to provide an enjoyable browsing experience with the Athena and the Viewty as a modem. Certainly no worse than using your SIM in the phone (in my opinion).
However if you're getting an EEE I'd wait for that and just plug the Viewty in!
BTW, how are you getting along with the Viewty? Is it enjoyable to use?
Also do you know what category of HSDPA it is? T-Mobile are supposedly about to inflate their service to 7.2mbps in some areas very soon.

Leon

The viewty is a very very nice fone. TBH I am just amazed that so much has been crammed into what is a FEATHERLITE phone!
I can use the touch screen no probs , i dont have sausage fingers. It does FULL screen DIVX playback superbly out of the box.Media streaming is much better than Ameo
can watch ORB with absolutley no Buffering and Mobile TV(which theAmeo cant do).
Nice music player , nice organiser
The software to sync is a bit crap but i have it working ok
obviously browsing is not as good as the AMeo due to screen size but thats what the EEE is FOR
I think this is gonna be a keeper , i just dont think 1 device can be a decent fone and a laptop type thingy
i have used big fones for a long time now, AMEO,MDA Vario, XDA 2i P900 and its really weird to have something so small that can do so much.
I am much more an entertainement and internet kinda guy so this new set up suits me great.
Just Sold my AMEO!
BTW, is this normal that during BT connection with external phone, the connection icon in the top bar shows no connection (two arrows with cross)?
When I'm connected with PC via ActiveSync it shows connection properly, however when use external BT modem, it doesn't recognize connection status.
Internal GSM module is switched off continuously.
How do I set my Tilt up as a BT modem for the Advantage? ICS does not work. How do I get the Advantage to look for a BT internet gateway?
Rather than doing this, whatabout alternative solutions such as:
- Getting a dual SIM card, one for Athena, and another for your little phone. In that way there is no need to make the little phone Athena's modem. One phone plan, one number. I'm not sure if your serviceprovider offers it.
- Use Athena as the primary phone, but use a blue tooth headset such as LG style I, or bluetooth watch headset called blue sound? You can them make and receive call with these little gadget instead of using the brick.
