The purpose of this project was to produce an indoor location system using WLAN IEEE 802.11b in Access Point (AP) infrastructure setup without additional external hardware. The system was developed in MATLAB platform that comprises of location sensing algorithm (Nearest Neighbor), signal strength database, client-server interface and graphical user interface (GUI). The basic idea was to build a database of signal strength information for various predetermined locations. Using the Nearest Neighbor algorithm, this database can be used to determine a particular location provided that a set of signal strength is given. As for the location sensing system's performance, it had a precision in terms of average distance error of 5 m and an accuracy of 72.2 %. The justification of these results was that noise, interference, multi-path effect, indoor propagation loss and random movement in the environment affectedRF signals.
