after thinking about it for a sec, you could probably just use null-detection with a directional antenna and take a couple of power readings to find the null at several locations. it's pretty old school rdf but i don't see why you couldn't code it up by reading s-levels of the incoming signal, etc. something using doppler shift with an array of antennas (it's 2.4Ghz so the antennas are small, this could be handheld) would just give you a bearing. lots of gear out there to do this, some of the better stuff is even "open source" if you will. a wifi doppler shift rdf box that could be velcroed to a laptop would be sweet. -- christian void cvoid () morphine com http://www.morphine.com/void/ _______________________________________________ Dailydave mailing list Dailydave () lists immunitysec com http://lists.immunitysec.com/mailman/listinfo/dailydave
