The continuous progress of the computer technology, the decrease of the dimensions and the power consumption that has taken place during the last decades, has enabled large computer companies to design new products that take advantage of the possibilities that the wireless networks offer. A very interesting implementation is indoor localization. The exact localization of a portable device is a complex process, considering that the signals arriving to the device are reflected and distorted, so that the exact location of the device cannot be precisely calculated. The aim of this work is to study the possibilities that the Wireless Local Area Networks (WLAN's) offer to indoor localization and to implement an application that will help to localize a device equipped with a WLAN's card supporting the IEEE 802.11b protocol. The application we composed (Wlib) uses a database with signal strength values stored and a mathematical model in order to estimate the position of a wireless device in the university library.
