I think the North American situation is somewhat worse than you are aware of. The assignment to Verizon vs AT&T have their duplexing reversed and are scattered over the 100Mhz range. Probably for good interference reasons, but the additional radio complexity is significant. http://www.phonescoop.com/articles/article.php?a=187&p=232
has a reasonable summary, although it could be clearer now the bands have been won.

Verizon's meager 10Mhz is the lions share. AT&T appear (from limited reading) to have two seperate 5Mhz allocations.

Also see http://wireless.fcc.gov/auctions/data/bandplans/700MHzBandPlan.pdf

As you point out, the USA 700Mhz spectrum is completely different to the European 800Mhz.


1'800MHz is also an option for Europe: there is a lot of not so used spectrum in that band. Manufacturers tend more and more to include that band on their roadmap. Most operators should be able to free 10MHz for the beginning of their rollout.

Possible scenario:

2.6GHz will be used with 20MHz carriers for hotspots

1.8GHz could be used for city-wide coverage

The digital dividend band will not be big enough for more than 10MHz channels in most countries. Usage could be in cities for deep indoor coverage or for covering white spots.


1.8GHz is an option in Europe but it's less preferred because of the performance.

In China there are two major players - China Mobile will use Band 39 for TDD. I heard that the Chinese government has put aside total 100MHz for TDD - meaning they're very determined to push TDD even further from today's TD-SCDMA. Another operator is China Unicom, who recently got the WCDMA license and in process of rolling out HSPA on 2100MHz. Pretty sure they'll go for 2100MHz FDD - they also have some 900MHz and 850MHz.

China is also trying to push TDD into other Asian countries by holding significant shares of other operators. But this is China Mobile only, not China Unicom.
