3G T-Mobile uSA frequencies question

[punky]

Hi,

Will the HTC Desire use 3G data with T-Mobile USA?

The HTC desire 3G frequencies are: HSPA/WCDMA: 900/2100 MHz
T-Mobile USA uses: AWS 1700/2100 MHz

Will it work? I.E. do both frequencies have to match, or just one? or is AWS different from HSPA/WCDMA?

It the normal GSM/data is quad band on the phone so should be no problems there (phone has 1900mhz and T-Mobile USA uses 1900mhz)

Many thanks in advance.

No.

T-Mo (USA) requires 1700 for 3G.

GSM will "work" (i.e. you will connect) however at Edge speeds (~250Kb)

Doh, suspected as much. Cheers dude.

The US 3G frequencies are ******ed, why can't they all just use the 2100 MHz like the rest of the world? Would make things MUCH easier...

i spent at least 1.5 hours researching this subject - and found a FCC chart showing 1700 band (actually its 1710 -1755) was the upload freq, and the 2100 band (2110 - 2155) the download. And thought it'd be fine, as long as i had 3G download speeds, i could live with Edge upload

someone on this forum pointed out, and i confirmed with a higher level tech at Tmo- if the phone doesn't have both freqs., Tmo will automatically put it on edge

Then the T-Mobile signal's building penetration would be worse than it already is, with the higher frequency.

Never had any issues myself on Tmob UK or Orange (prev carrier) where others have.

Fair enough, but T-Mob UK and Orange are not here in the states.

I know that. I was refering to your penetration issues of using that frequency

Their GSM networks are both 1800, and actually have very good coverage - certainly Orange's GSM coverage is very good.

I know that. It still doesn't change the fact that I still have "no connection" inside (4) different stores I frequent around my town. As soon as I am outside of the door, I get full bars 3G. Having a tower in close proximity can help overcome building penetration issues, unfortunately, T-Mo USA's network is not that robust stateside, on its 1700/2100 freq.
