One of the guys on this list (Hi Dave) will know more than I do, but
basically the ISM band (2.4 GHz) is defined differently here than in the US,
but the ACA (in a wise move) have allowed US spec gear to operate at a lower
EIRP level (0.2 instead of 4W).
And yes, at least some gear can be reprogrammed to Aussie specs.
FYI, the Aussie band limits are 2400 - 2463 MHz. The US band is 2400-2483
(or thereabluts, don't quote me on the exact figures). Because of the
nature of spread spectrum, it is not always possible to "not use" the "extra
bit" - the spreading sequence usually needs a tweak.
As I said, this is sometimes possible in the card's NVRAM.
