New WiFi positioning system, the Hitachi AirLocation

Hitachi WirelessInfo Venture Company has developed an 802.11b Wifi location transmitter/receiver system, and has slated its release as early as September. Of course, the downside is that since it's not GPS you'll need a local mesh grid of AirLocation waypoints for operation, but at least the transmitter unit is 2.3 x 1.6 x 0.8-inches, and has an integrated motion sensor which activates the device if it's moved. Supposedly the transmitter also has up to five-years battery life via its motion sensor, which we're assuming means that it's facilitated by the same kind of internals that supply kinetic watches with energy. That, or the battery life thing is just a dirty, dirty lie. Either way, it's surely going to be a bigger hit than the Bluetooth lojack, not only because of range, but ubiquity and, well, it's WiFi for god's sake!
