 \add{To initially set up the system we only require a blueprint to create the floorplan, some Wi-Fi infrastructure, without any further information about access point positions or parameters, and a smartphone carried by the pedestrian to be localized. 
 The existing Wi-Fi infrastructure can consist of the aforementioned Wi-Fi beacons and / or already existing access points. 
 The combination of both technologies is feasible, depending on the scenario and building. 
+Nevertheless, the museum considered in this work has no Wi-Fi infrastructure at all, not even a single access point. 
+Thus, we distributed a set of \SI{42}{beacons} throughout the complete building by simply plugging them into available power outlets. 
 Despite evaluating the novel contributions and the overall performance of the system, we have carried out additional experiments to determine the performance of our Wi-Fi optimization in such a complex scenario as well as a detailed comparison between KDE-based and weighted-average position estimation.}
