Today’s Wi-Fi Fear: Thieves using RDF to find notebooks

An article on NetworkWorld.com made me chuckle today…  Apparently the Bad Guys are now using Radio Direction Finding (RDF) to locate hidden notebooks because their 802.11* wireless was enabled.

It seems amazing to me that it has taken this long for anyone to realize that if a ntoebook or any other device is “wireless”, that it is transmitting a signal, which can be located.  RDF is actually a sport and ham radio operators have been doing it for years…  We use high gain, directional homemade and sometimes professionally made antennas, receivers and sometimes doppler systems to zero in on a hidden transmitter. This is called “foxhunting” in the USA for the casual participant.
