A comparative study of Wi-fi and bluetooth for signal strength-based localisation

Abstract

With the growing need for indoor localisation solutions, this paper investigates the practical applications of wireless networking technologies based on the empirical study. By comparing between the two most widely used wireless technologies, aims to identify which technology, between Wi-fi and Bluetooth, is more capable in RSS-based localisation. Field experiments were conducted in order to collect the data to model the propagation of the two technologies. This study demonstrates that, through comparing the derived models to empirical data, Bluetooth has the potential to improve indoor localisation methods due to its more accurate model.
