Location Determination in a Wireless LAN Infrastructure

This research addresses the design, implementation, and evaluation of a people location service using the wireless network infrastructure at Carnegie Mellon University. The determination of the location of a mobile computer user has several applications. A person locator has been developed to accomplish this task. A user’s location can be determined both indoors and outdoors while on campus, and at a higher resolution than the Global Positioning System. Although the system requires only a minimum of extra hardware, its results provide a high degree of accuracy.
