|Project Description: ||The location sensing mobile system for electronic campus tours runs on a laptop computer, to provide users with a “you are here” view of their current location and a direction finder feature to help them tour a campus area The system operates on a network of access points that allows users to detect and share their location information, and provides an interface to query and monitor the location information. This system implements the location sensing network using Ekahau Real-time Location System (RTLS) and 802.11 Wi-Fi stations. Ekahau RTLS is an automatic location identification software that relies on storing and remotely retrieving data using Wi-Fi access points. 802.11 is a standard for wireless local area network (WLAN) with over-the-air modulation techniques. The focus of the system is on designing a building-wide location infrastructure, location middleware to allow location data to be handled in a uniform and secure way, and a tour guide application to demonstrate the system and serve new visitors. This project prototypes a location sensing system for the second floor of the university library.
