3G/HSDPA Question.... Kaiser/T-Mobile


Recommended Posts

Hi,

Probably a stupid question, but what are the major differences between 3G and HSDPA.

I'm on T-Mobile with my TytnII and when using data I mostly get the 3G icon, but sometimes I get the HSDPA icon - which one's newer/faster? And I'm assuming that both are included in my web'n'walk data plan???

Cheers.

Just a quick thanks to these forums, they've easily been the most informative over any website over the HTC devices, notably the TytnII - thanks to you guys, I grabbed mine from T-Mobile last week (second phone call lucky - the first lady denied they had any ;) - hung up, tried again).

HSDPA is faster and newer, and yes, they are both covered by web'n'walk. enjoy your Kaiser, you lucky so-and-so java script:add_smilie("<_<","smid_12")

Thanks. So how does the phone decide which to use?

If you're in a 2G area only then it will only use 2G (and just see a G symbol)

If you're in a 3G area it will use 3G (and see a 3G symbol)

If you're in an area with HSDPA it will use that (and see an H symbol - but only while downloading data).

Ahhh.. only while downloading data do we see the H icon... makes sense I guess ;)

Just remember the power drain is HSDPA drains more power then, 3G which drains more power then G

HSDPA > 3G > G

Does anyone know if there is a map of HSDPA coverage? I'm in central London (right in the middle of the City) and according to my phone, I only have 3G not HSDPA.

Anyone else managed to get the illusive "H" to appear on their device?

Yeah, been browsing and downloading over HSDPA all morning. Very impressed with the speed.

I'm in an office in the suburbs of Cardiff. Was quite surprised that it picked up HSDPA. Maybe there's a TMob mast on the roof of our building ;)

I've got pretty poor coverage where i am but when i get 3G and start downloading a lot it flicks from 3G to H

It also depends on your subscription speed.

Here in the Netherlands, my subscription is capped to max 192 Kbps (unlimited traffic btw). I have never got the H icon, always 3G.

I called T-Mobile and support said that unless I got the most expensive subscription, capped to max 1.8 Mbps, I will not get the H icon.

Is that true? I dont know, but that was the information from the T-mob NL support.

Hmm...I think in the UK, TMob don't cap speed based on subscription.

OK, after looking into this I may be wrong - can anyone confirm this?

Ok, I checked the Uk site, and I can't find a similair data plan that we have in Holland

Nah, T-Mob don't cap HSDPA speeds on the Kaiser. They do have summit like a web n walk max plan but thats for laptops.

I've tried a speed test on my Vario III at http://www.bandwidthplace.com/speedtest/ and managed to get 1.2meg download speed in North London (Islington).

Does anybody else know of any good speed test sites?
