https://en.wikipedia.org/wiki/33-centimeter_band has more info on the 900MHz band they're using, which is an odd choice because it isn't recognized outside Region 2 (Americas).

900MHz seems a curious choice to me as an Australian, because I know my mobile phone uses 850 and 900MHz to talk to the mobile towers. Attempting to use 900MHz for wifi wouldn't get you very far due to all the interference.

Not to mention all the regulatory hurdles.
