 Basically, any kind of \docAPshort{} providing RSSI measurements can be used for the above.

 However, most buildings do not provide a satisfying and well covered \docWIFI{} infrastructure, e.g. staircases or hallways are often neglected for office spaces. 
 This applies in particular to historical buildings, as discussed in section \ref{sec:intro}.
 To improve $\docWIFI$ coverage we are able to distribute a small number of simple and cheap \docWIFI{} beacons.
 As beacons we use a WEMOS D1 mini, which is based on the ESP-8266EX \docWIFI{} chip \cite{Wemos}. 
 The building considered in this work has no \docWIFI{} infrastructure at all, not even a single \docAPshort{}.
-Nevertheless, our method also allows to distribute beacons in the whole building by just plugging them into available power outlets.
