G2 and UMTS bands

[juliemeister]

On T-Mobile's own website and other blogs it says that the G2 only has the Band IV UMTS band, which is AWS 1700/2100.

Is that a typo? Does it mean that the G2 will not work in Asia and Europe?

Damnit! Someone please bring me the good news. Thanks!

Since band IV is 1700/2100 and band I (Europe) is 2100, it's trivial to support band I on a band IV phone - I'd be surprised if it didn't support it in hardware at least. Time will tell, I suppose.

[dubz2st]

there are two versions: the G2 supports 1700/2100, and the Desire Z is the European version with 900/2100 3G bands.

[juliemeister]

But does the G2 support up AND down on the 2100 band?

[keyguy5]

I have unlocked G2 and I can verify 3G does work in Europe. The Band I is there.

[juliemeister]

That really sucks! It's a good thing I returned mine. I travel to Europe often. I'm sure this was purely done because they don't want the G2 to take sales from the Desire Z. I hope they don't do the same thing with the new MyTouch. If T-Mobile continues this I might have to consider AT&T (damnit!).

The G2 has the Euro 2100 band.

The 1700/2100 you see indicates the 1700 is the AWS band, while the 2100 is the 2100 is the Euro 2100 band.

[juliemeister]

But the AWS is 1700 down and 2100 up. Unless it can do both up and down on 2100 it won't work in Europe.

The G2, as well as any HTC T-Mobile Android since the G1 Dream, has both the 1700/2100 AWS _and_ Asian/Euro 2100.

They do this to support T-Mobile Europe for roaming. Guess who owns T-Mobile USA?

My first Android is an unlocked T-Mobile branded MyTouch 3G which I use on Asian 2100 bands on Asian countries.

And UMTS2100 is 1900 down, 2100 up, and GSM850/UMTS850 doesn't even run on 850MHZ (the uplink stops at 849MHz and the downlink starts at 869MHz. Point is, stop saying what you just said. That goes double for T-Mo, since they should know better. It just confuses people. Call it Band IV, AWS, or UMTS1700. Don't even mention the downlink. It's irrelevant.

And the reason why all phones aren't penta-band like the Nokia N8 is because every band you add means you have to pay additional licensing fees. It's a crappy system, but it's how it works. There is no, repeat NO, technical reason.

I'm not questioning any other T-Mobile phone. G2 is the first 3G T-Mobile phone I've seen that doesn't mention Band I in the specs, which is why I've questioned it.

And UMTS2100 is 1900 down, 2100 up, and GSM850/UMTS850 doesn't even run on 850MHZ (the uplink stops at 849MHz and the downlink starts at 869MHz. Point is, stop saying what you just said.

I wasn't talking about the exact frequencies but the generic terms, which is AWS for T-Mo USA and 2100 for Europe, although I know it differs slightly. Otherwise, I'm not sure what you are saying about AT&T. As far as I know, the AT&T phones I've looked at all offer Band I.

Here is how it works:
In order for down link to work you have to have up link. You need to send some pockets of data to request data. And you can't have 2G (GSM freq) for upload and 3G for download to work at the same time.

Now Band I (2100) for Europe and Asia has upload freq 1920 - 1980MHz and download freq 2110 - 2170MHz. Band IV (1700/2100) has upload freq 1710 - 1755 MHz and download freq 2110 - 2155 MHz. Band I is also called IMT. Band IV is called AWS.

Another difference between those 3G Bands are different channel numbers on which those freq are working. So channels on Band I (2100) are different than on Band IV (2100) for download.

I'm 99% sure that MyTouch HD will not have Band I . I looked at FCC website. The best way to check it though is to unlock the phone and go to Europe.

I'm 99% sure that MyTouch HD will not have Band I either. I looked at FCC website. The best way to check it though is to unlock the phone and go to Europe.
