Wi-Fi Fingerprints -- the End of MAC Spoofing?

judgecorp writes, "Wireless devices can be identified by variations in their radio signaling, known as their 'transceiverprint,' according to research reported in Techworld. The Canadian researcher, Jeyanthi Hall, related the prints to MAC addresses and got a positive ID for devices connecting to a Wi-Fi network, claiming 95% success with no false positives. Once they work out how to do this without a dedicated signal analyzer and neural network processing, it's the end of MAC spoofing on wireless networks."

Anyone seriously into wireless security / hacking probably has 20+ wireless cards. It is common knowledge that a wireless card can be identified by its traffic, so why not just buy one of each vendor's cards and use the relevent one during each hack?

If you RTFA, you would have seen that manufacturing variations yield differences even among the exact make and model -- e.g. that minor circuitry, amplifiers and antenna variations differences yield a unique signature.
