The objective of this project is to implement outdoor user location which is build on top of IEEE 802.11 technology. In this solution, four laptops are used where three of the laptops will serve as the reference points and the other one will be the target. The signal strengths from each reference laptop to the target are measured to serve as arguments for localization algorithms, which is triangulation. In order to perform this algorithm, the locations of the three reference laptops and their separation distance from the target laptop are needed to be known. The locations of the reference laptops are arbitrarily assigned but the separation distances are estimated based on the signal strength information received by the target laptop. To find the relationship between the separation distance and signal strength received from each reference laptop, a series of signal strength measurements are conducted. From the collected data, the radio propagation models are determined. A Graphical User Interface (GUI) has been developed to make the process of location determination become less complicated and more user friendly. At the end of this work, the site testing has validated that this algorithm can be used to determine the user location in outdoor environment with considerable accuracy.
