Emulating a wireless access point

[Steve Skoronski <skoronski () ctidata com>]

greetings,

        I have heard about wireless LAN attacks that involve 'overpowering'
or competing with the real Access Point with your own. The idea is that the
clients will automatically switch to your, higher powered AP, authenticate,
and then you can sniff the authentication sequence.

        Has anyone seen software to emulate this on a PC/Laptop with a wi-fi
card? Or should I go look for a used AP? 


TIA


Steve
