Hi guys,
I've got a mobile with EDGE/HSCSD...
My question is (Sorry but I don't know nothing about speed and irda and EGDE/HSCSD.):
if I use mobile like HSCSD modem for my laptop and I use irda as connection from bobile to laptop... is it okay using HSCSD over irda or the irda speed is too slow?
irda is 115.2 kbps.
HSCSD is 43.2 kbps (sometimes a bit more, depends on network)
EDGE is theoretically 384 kbps but I don't think there is any network (or mobile) allowing such speeds. Usually it's around 100 kbps.
So it should be no problem using irda for your connections!

Looking at sites on bluetooth devices it shows the connection speeds at 750KBs. Is that bits or bytes? and why does the xda2 not connect at speeds like that. I thought USB activesync was slow and then i found BT to be twice as slow if not 3 times!
Anyone know the data transfer speeds through USB - XDA2
If there is no GPRS available or much too expensive (roaming) i prefer to use HSCSD. I have configured my hw6515 to access my ISP via CSD. I was using a HP Jornada 568 with a Nokia 6310i before, where I communicated to to the Nokia phone via bluetooth. The nokia was opening a HSCSD connection to my ISP. Now I would like to do the same with my hw6515. It seems to me that the hw6515 only connects with Normal Single Slot GSM Circuit Switched Data (CSD) @ 9600 Kbps. I am looking for a way to configure High Speed Circuit Switched Data (HSCSD) Multi-Slot GSM data calls of maximum uplink/downlink speeds of 43.2Kbps/14.4Kbps or 28.8Kbps/28.8Kbps.
On the Nokia 6310, I modified the dial string to force the modem to use HSCSD channel bundling in the following way:
9.6kb: AT+CBST=0,0,1;+CHSN=1,0,0,0<cr>
14.4kb: AT+CBST=0,0,1;+CHSN=2,0,0,0<cr>
19.2kb: AT+CBST=0,0,1;+CHSN=3,0,0,0<cr>
28.8kb: AT+CBST=0,0,1;+CHSN=4,0,0,0<cr>
43.2kb: AT+CBST=0,0,1;+CHSN=6,0,0,0<cr>
or
Automatic Negotiation
AT+CBST=81,0,1
Does anybody know how to configure the iPAQ hw6515 to do HSCSD?
:roll:
been playing with the vario 2 for few days now, and im very impressed, had a mda pro previous to that. I have web n walk pro, on the phone i get upto 1.2MB internet speed which is what i expect dure to HSDPA, but when i connect the phone to laptop as amodem via usb or blueetoth i get 364KB (the 3G speed).
Why is there a difference in speed? maybe im doing something wrong.
any help would be much appreciated.
Ok, you need to edit the modem within networking in windows(on your pc). You can change the connect speed from a pull down box.
Don't forget that the Bluetooth connection itself is going to slow you down... and even if you have a Bluetooth 2.0 card, the TyTN does not support EDR...
As such, I'd be very surprised if you got any faster than you're already seeing...
I'm sure that as soon as somebody figures out how to make it work, a tethered USB connection will be faster than a Bluetooth one... but this is still not possible...
Try Tethered USB. It's much faster and allows for your full speed. Check the Wiki FAQ. There's instructions there.
Has someone done a usb dial-up connection or usb wireless-modem connection with TyTN? My TyTN reachs 1.5-1.6 Mbps but when a set a dial-up bluetooth connection it only reachs 300 Kbps (with online speed tests). And i cant plug it as wireless usb modem (nothing happens in any of my computers). Some idea?
Thanks
since the TyTN does not support EDR, it's speed is limited, so your getting the max out of BT DUN. Instructions for the USB DUN are included on your CD that came with your device and it has the proper drivers in there. The files (Instructions + Driver) can be also downloaded here:

Has someone done a USB dial-up connection or USB wireless-modem connection with TyTN? (not with htc universal or other. I say with TyNT)
Thanks
Hi,
I have att 8525 and when I connect it to the computer and do internet sharing my max speed is about 260kbps. If I browse internet on PDA the speed is about 700 kbps. What could be the reason for slower internet on PC? I use both USB cable and Bluetooth PAN with the same results...
How do you measure the speed?
Try WiFi sharing - Bluetooth and/or cable can be limiting you.
I have an 8525 with Schaps ROM tethered to my PC. The phone is showing HSDPA speeds which I thought was up to 3.6mbps? But my tethered internet speeds stay stead at 1.2mbps down/~400kbps up. Is this the fastest I can hope for or is there a way to increase it? Tethered through USB by the way.
