Airshark is an experimental application bringing detect-and-avoid frequency-hopping to previously dumb Wi-Fi cards, without the addition of any new hardware. Created by three boffins at the University of Wisconsin, Airshark uses the limited intelligence of existing Wi-Fi cards to spot other protocols hanging out in the 2.4GHz …

I think a bit more detail explaining the MAC layer would have been better rather than just using the word Protocol because it makes the article difficult to understand
Why are microwave ovens communicating on the 2.4GHz band? They're plotting something! Don't say I didn't warn you!!!
Mine's the white one with the sleeves that tie up at the back...
Are we sure?
"This kind of thing is already possible, but only using spectrum analysis hardware that would be prohibitively expensive to put into a Wi-Fi router."
Someone should tell AVM. Their Fritz! wireless routers have been showing interference from other sources in the WiFi bands at the click of a checkbox for some time. They'll be delighted to hear that this is actually impossible without a load of expensive kit they don't provide.
to triple available bandwidth...
Just knock on the door every BT Homehub user and ask them to use a REAL router rather than BT's mickey mouse POS
Hope they can make it through the seven circles of patent hell to bring the tech to market.
Software Radio Rules. How much more to say is there than that?
One Chipset to rule them all, One Chipset to find them,
One Chipset to bring them all and in the software bind them
Does this mean Ethereal is going to change its name again?
Isn't this rather like the radar detection/avoidance necessary when operating in the 5 GHz range?
Nice writing, as always
Great job, Bill Ray. Among the many scribes who aim to clarify the what and why of wireless, "No-o-body does it better."
