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.
