AFAIK in Italy they are licensing WiMAX at frequencies of 3.4Ghz, while this WiMAX enabled tablet is set at 2.5Ghz.
So I suppose that us, in Italy at least, will be out of luck this round.
Unless Nokia comes out with a new EU version of the WiMAX version of the N810.

As far as I understand it the WiMAX has a pretty wide range of working frequencies, from 2Ghz up to 66Ghz.
The higher the frequency, the higher the bandwidth, the higher the battery consumption, the lower the penetration...right ?

Anyway, the choice of which frequency a WiMAX enabled device can talk on is a matter of the local government, as far as I can tell.
As usual EU and US looks like are following different paths.
EU is pushing bandwidth, while US penetration/power consumption.

In the end, the user pays for it.
If all I have written is true, then my WiMAX enabled device is already limited to only those countries that licensed the 3.4Ghz frequency and won't let me chat in the US.

Welcome to the real world, my dear.
