Development of Geographical Location Estimation System for WiFi Users in Campus

We have developed a geographical location estimation system for WiFi user in campus to help network administration. We use WiFi radio wave to estimate users'location. The system measures strength of radio wave between WiFi access point and a user's PC. We have developed and implemented calculation formulas. The system calculates distance between the pair for the estimation. Then the system shows the estimated user's geographical location on the campus map via Web browser. A network administrator may know users' geographical location easily to use this system.
