3G variant mystery

[ghatothkach]

hi

The 3G variants 850, 900 are still a mystery... Does not affect "static" users, but very valuable to mobile travelers.

Any information on these ?

will 2100-UMTS be supported on both variants ?

seconded. It's not clear in Korea what is used - I'm told it's neither 850 or 900 - but without speaking Korean I'm sort of lost. I'll need this in Korea though, so....

Anyone smarter than me?

Korea is mainly on 3G so your carriers their are most likely running voice and internet over the same service.

as long as it supports all the 3G freq. the you should be good to roam anywhere there is a 3G network, most of the world at the moment. the 850 and 900 freq. are mainly for voice transmission most 3G networks are on 1900MHz US (depending on carrier) and 2100MHz rest of the world. but we are still waiting to see what type of chip has been used on adam...

Which I think is absolutely ridiculous, as this is one of the key selling points for me and a lot of people. But hey, who am I? I didn't get a chance to pre-order nor would I if I had the chance, so I am sure the info will be out before I even have a chance to purchase, so this doesn't so much affect me as it affects everyone that pre-ordered.

Korea and Japan dont typically use the frequencies we want making all the phones unusable. I had a stopover also once in Incheon and none of the phones we had worked. I dont know if its a frequency issue or if they use a totally different technology, but these 2 countries have some problem

Looks like, for my interest/travel areas
AT&T USA 3G => 850/1900
T-mobile USA 3G => 1700/2100 AWS
UK, Hong Kong, Taiwan, Singapore => 2100
India 3G => uplink 1900/downlink 2100

most of the phones have 2100 supported, so looks like if it can work with
ATT then it will work in other areas also....

tmobile-USA is a odd man out doing 1700/AWS, I really doubt if they will have a separate model which will work with t-mobile.. really eager to see what spec they
have for 3G support.

I too was hoping to bring the adam with me on my travels for email, photo editing, etc and avoid a clunkier netbook. This band issue is a bit of a bummer and NI just gave me the standard shipping address answer in their email

I bought a Nokia 3120 Classic cell phone while in Indonesia. It is a Quad-band phone, so it can do voice and data (regular GPRS and 3G) in both SE Asia and the US. It works fine on the T-Mobile system in the US and Telkomsel in Indonesia. I believe it also works in Europe, and might also work just fine in Korea and Japan.

My point: a quad-band system is a simple solution that makes the device universal. This is clearly the best approach -- it satisfies everyone and eliminates the need to maintain multiple configurations for various markets. The cost increase for a Quad-band over a single band is minimal (on phones), so I imagine the simplification to fabrication and stocking would eliminate or significantly reduce the cost difference for the Adam as well.

It was my hope that the Adam would be universal.
