Gobi 2000, AT&T, and HSUPA

[Main Target]

So does anyone have experience with this WWAN connection and whether or not you can get it to connect to AT&T's HSUPA instead of HSPDA?

I know I have it in my area as my android phone is able to access the HSUPA network, but when i connect up my T410 I only am able to connect via HSPDA

Call AT&T and ask them for help.

Seems as if the card supports HSUPA so you should be getting it. The software probably just doesn't display the difference. What's your max upload speeds you've gotten?

Like 600k, VERY slow.

My phone gets 1.3 Mb up.

Weird, anything over 300 should be HSUPA since UMTS is 384/384. HSDPA only changes the download speed so if you are getting 600 then you are going close to the 2.0Mbps max of the card anyways.

Which phone do you have? Maybe your phone has a faster HSUPA speed than the card.

[Main Target]

The speeds are consistent with HSPDA on my phone. When I loaded the HSUPA kernel/modem onto my Samsung Captivate, upload speeds shot up to 1.3 up.


AT&T has purposefully crippled their HSPDA network methinks

[SHoTTa35]

The galaxy S devices support HSUPA:

HSDPA:HSDPA 7.2 Mbit/s
.HSUPA:HSUPA 5.76 Mbit/s

As you can see, it should get better results than the Gobi2000. AT&T is upgraded to the faster HSUPA but as with any wireless tech, you wont see 2Mbps on the Gobi, you definitely wont see 5.7 on the iPhone 4 or Capitavate either.
