I have also read the Atheros documentation for ANI (for a different hardware version but it says the operation is similar). Are we able to see physical layer parameters like signal level / correlation / channel state information, or are they hidden inside the hardware? ~ w ~ On Thu, Oct 10, 2013 at 10:05 AM, Adrian Chadd wrote: > I'm not sure.
