The 2.4GHz band isn't unlicensed, it's class-licensed.
The class license describes it as being suitable for sub-100mW
spread-spectrum transmissions. There's an EIRP limit as well (so
you can't couple your 100mW transmitter to a high-gain antenna and
blast birds out of the sky at 100 paces :-)
Whatever spread spectrum systems use the license ought to be capable
of coexisting without interfering with each other. So I should still
be able to use my 802.11g wireless network interface while someone in
the next room is talking on their 2.4GHz digital cordless phone, and
while someone else with a FLARM unit is doing a beat-up over the car
park out the back of my house.
I can't remember if the class license includes limitations on whether
the transmitter needs to be terrestrial. If it doesn't I suppose it
could be airborne, but it'd have to meet all the other license conditions
as well to pass muster.
I can't be arsed looking it up, but there's a copy of the license on
the ACA's website if anyone is interested.
