NEWS: Siemens to resell Wi-Fi locator tech

<http://www.theregister.com/2007/05/23/siemens_wifi_tracker_option/>

Electronics behemoth Siemens will partner with Finnish firm Ekahau to
resell the Nordic developer's crafty Wi-Fi location technology.

Ekahau's trick is to locate a Wi-Fi-enabled PDA, computer, Voice over
WLAN (VoWLAN) handset, or tag unit using existing 802.11 WLAN access
point antennae. The company claims one metre accuracy when the object
to be tracked is within range of three or more base stations.

Computers, handsets, or PDAs to be tracked must be running the Ekahau
client service software; the tags are a specialist hardware solution,
significantly more complex than an RFID chip. The client software is
available as a free download, but it doesn't seem to do anything
interesting on its own.

Have you by any chance tried to see if the "hidden AP detected" feature
works. I don't have a supported card and a touch of curiosity.
