 The access points are Intel NUCs running a patched Linux to enable FTM support.
 In total we're using eight APs based on Intel WiFi cards.
 Four of them are based on Intel Dualband-Wireless-AC~8260 cards configured as described by \etal{Ibrahim} \cite{ibrahim2018verification}.
-The remaining four are based on Intel Wireless-AC~9462 modules and run a recent Linux kernel where the iwlwifi driver and hostapd are already prepared to support FTM.
+The remaining four are based on Intel Wireless-AC~9462 modules and run a recent Linux kernel 5.3.7 where the iwlwifi driver and hostapd are already prepared to support FTM.
 However, the driver still requires small manual changes, as a global boolean flag needs to be set to activate the FTM related code.
 In addition, the firmware of the card returns that the chip is not calibrated for FTM.
 As a consequence the driver disables FTM responder functionality.

 Opposed to \etal{Ibrahim} \cite{ibrahim2018verification} findings no single constant offset which significantly improves the measurements across all device combinations could be found in our tests.
 However, the overall error of the device combinations is reasonable small and its distribution is mostly Gaussian-like, which justifies the basic applicability of the technique and devices for indoor positioning.
