Systems for indoor positioning using radio technologies are largely studied due to their convenience and the market opportunities they offer. The positioning algorithms typically derive geographic coordinates from observed radio signals and hence good understanding of the indoor radio channel is required. In this paper, the authors investigate several factors that affect signal propagation indoors for both Bluetooth and Wi-Fi. Their goal is to investigate which factors can be disregarded and which should be considered in the development of a positioning algorithm. Their results show that technical factors such as device characteristics have smaller impact on the signal than multipath propagation.
