Abstract

Global Positioning System (GPS) is widely used as public location and positioning system in locating and localizing geo-location coordinates of user. However, this application signal is limited, not operational, not available and inefficient for indoor environment. Therefore, the purpose of this project is to develop localization and positioning system utilizing Wi-Fi signals. Wireless position estimation is based on distance measurement in determining the coordinates of user. Scene analysis which called fingerprinting technique is chosen in this project with measurement of received signal strength at specific locations. This fingerprint positioning algorithm has two phases to go through which is surveying phase and online phase. The unknown location of user will be located during online phase based on database comparison that has been collected on surveying phase. MATLAB Graphic User Interface was developing as user interface for simulation purpose. Several analysis has been done to determine the accuracy and effectiveness of the positioning error due to numbers of access point and environment traffic condition.
