Abstract

In this thesis I have explored the possibilities of using mobile phones based on Android platform for indoors positioning. An application that enables such positioning was developed and tested especially to confirm my thesis. The first part of the thesis explains the various kinds of location-based services, their usefulness and problem possibilities. This section also introduces the reader to the field and explores the potential of such technologies and correlated methods. Their comparison has led me to focus on using the specific method of Location Fingerprinting (LF). This method determines the position in space relative to a unique value of the wireless signal intensity. In the second part of the thesis this technique was implemented in a software solution using two programs. The first is a generic one used to capture the reference points, the second one is used to practically demonstrate a mobile phone being used for self-positioning within the building of the Faculty of Computer Science (in Ljubljana). The third part of the thesis is dedicated to testing and exploring the potential for further research and solutions that would be even more accessible and user-friendly.
