Thank you very much for the response.
Do you mean that the hardware can also detect other signal, even it's
not a valid 802.11 one, say 802.15.4 if they are working in exactly the
same channel(eg. 802.11 ch 11, 802.15.4 ch 23)?
I am just wondering if a WiFi hardware would do backoff when other
non-802.11 signal with same frequency exsist.
Best regards,
Wei Zhang.

However my project requires that the WiFi NIC could feel other 2.4G signals, like bluetooth or 802.15.4, as long as their signals are above the threshold. So I am wondering that if the hardware or even ath9k driver support the energy based modulation.
