There might be public frequencies yes... But me personally, well, Ill have
to do some more research on radio ethernet.. I have no idea to which
frequencies those cards perform at... I'm sure though that if the
frequencie is high / low enough, I might be able to get something going...
Especially after our telco's monopoly expire (which is why radio ehternet
is a nono at this stage).
Fiber... WAAAY to expensive in South Africa :(
