According to Nikkei Business Publications — “Hitachi Ltd and Hitachi Cable Ltd announced they would jointly launch a new location detection system called “Hitachi AirLocation.”
The system went on sale on November 20.
The new system uses the IEEE802.11b-based wireless LAN. It works both indoors and outdoors, and has a small error range of 1-3 meters, compared with the global positioning system (GPS), which can be used outdoors alone and has an error range of about 10 meters.
The system consists of a location detection server, a management server, more than five dedicated base stations, wireless LAN devices, and software designed for the system. Hitachi was in charge of developing the software, and Hitachi Cable, the dedicated base stations.”
