@boba does that site say that 3g 2100 and HSDPA are the same thing?

Does anyone know if wherever 3G is available HSDPA (or 3.5G) is also available/used?

@masseur I too found that out but couldn't get much more. They dont even have a coverage map on their site!

I like the HSDPA that I get. It makes browsing when out and about on my laptop.

Hi Masseur,

Talking of making full use of HSDPA have you seen the soon to be realeased Toshiba Portege G900 Pocket PC with a 3" WVGA wide screen and all the tech you could possibly think of dependant on price i am seriously tempted by this. Or possibly the Motorola Q9 as my next device and my introduction to Windows Mobile 6 as both look very interesting and i much prefer the Q9 against the Z8 despite it's spec i just can't get past it's horrible plastic construction.

800x400 in a 3" screen? I'm not sure about that. vga on the 3.6" screen of the universal was only "ok". the others specs don't look so hot and still only 64mb memory and the moto doesn't appeal unfortunately

nah, I'm waiting for the tytn successor or some other offering from HTC for my WM6 machine

Hi Masseur,

I'm still waiting to see what processor and Ram the Tosh comes with and have been a fan of the Moto Q since it was announced just very interested to see just how good the Q9 actually is in the flesh and how it performs.

I can see how the Q9 would be of interest to E61 users but I'm sorry, its just too big for me.

You need to tick 3G Broadband if I remember correctly.

Improvements of HSDPA over standard UMTS is not just more bandwidth, it is also a drastic reduced round trip time (rtt) for data packets. With normal UMTS you have a rtt between 100 and 200ms (thats at least what I saw with my colleagues laptop), while with HSDPA you have a much lower rtt. Now when you want to use voice over ip (or remote desktop , or ssh etc), this is a big difference...
"As well as improved data rates that are associated with HSDPA one of the key benefits that are seen is the reduction on latency, improving the round trip time for applications." (source: http://en.wikipedia.org/wiki/Hsdpa)

one question i have with HSDPA is, is it supposed to be more power efficient than standard 3G? the reason i ask is because if you look at the specs of the Z750, the talk time/standby time in UMTS mode is 3:30/350hrs.

for HSDPA/EDGE/GSM it is 9 hrs/400 hrs. hmmm...
