Finland Chooses 1800MHz for LTE
Figures...
When will there be an official standard so that it's literally any device on any network?
And please don't say it can't be done, it is already done in non-mobile phone radios. I just don't think the research or want to do anything is far more then can't.

I was thinking the same thing, but I also think its about time chip makers should be able to make either multi-freq radios, or an adaptive chip design for each locality.

I read on another site (at least 2 years ago)that phone makers were looking at making the frequency bands work software based, rather than hardware based. That way, if another frequency band is needed, then the new band could be added to the phone, rather than the phone not being able to access the new band. I only wish I remember where I read it at.

A huge majority of the carriers globally (US included) choose LTE, yet they can't agree on a band.
Simply put, no universal block of spectrum is available (or able to be cleared) across all countries.

Just short of never.

Think about it: GSM is on 4 bands already, UMTS/HSPA is on 5 bands (850/900/1700/1900/2100).
So to have a truly global phone you would want quadband GSM, 5-band 3G, and at least tri band 4G. That's a lot of radios, not even including BT, WiFi, or GPS.

Wimax=BetaMax
Unless WiMax catches on with other carriers, then it might not matter. Besides, at least in the US, Clearwire (Sprint) is using WiMax, and it's in the 2.5ghz band. Whether Sprint lauches it in the PCS band is unknown yet. For now, they're not using PCS for WiMax.
On the technology side, we are finally moving to one global standard, and that's LTE. It's actually very exciting.
As far as frequency bands, radio spectrum a precious resource. As more people use phones, and use more data, we need more spectrum to handle that. That means more bands, not fewer. In any part of the world where you have a frequency band dedicated to phones, the mobile companies using it have typically paid billions to license it, and they're not going to throw that away... ever.
In the US, the 850 and 1900 bands won't go away when CDMA and GSM die; those bands will be instead be used for new technologies like LTE. We can look ...

Now if we can just get a radio built that can support all frequencies and use software to tune in and receive the frequency we would be away from the "X-Band" phone hardware requirements for global roaming.
We as a world society need to embrace the global marketplace we live in and create products, especially the ones we rely on for our communication with the rest of the world, that are able to move where ever we go. The world i...

That is a pipe dream.
Software defined radio does not overcome the limitation that such devices still must have one or more antennas (physically or electrically) optimized for each & every desired radio frequency band. That force runs counter to the one driving consumer's fervor for increasingly cheaper, smaller phones w/ wholly internal antennas.

Also, how do they get by with using the 2100 for coverage overseas, when we here in the US need the 850 to reach places where the 1900 can't travel and penetrate well?
I don't know if there was 1800 band frequencies that either weren't used at all, or Finland was freeing up for LTE. So the 1800 band they're using might be a different set of 1800 frequencies for this purpose. While not as good as anything under 1000mhz, but better than the EU going wi...

Also, I think in Asia, or some place overseas, they use the 1700MHz band but not the AWS Band 4 1700/2100MHz band.
I believe it's Japan. I don't know about South Korea on their frequency bands.
