Debug Freifunk wifi nodes with the popular Wifi Analyzer app - and get the human readable node names displayed, instead of their MAC addresses.
Wifi Analyzer has an "Alias" feature, which can import a list of aliases from
a file WifiAnalyzer_Alias.txt from your phone's SD storage.
This app will generate such an alias file in the correct location, so you can import it: open Wifi Analyzer and do Settings > Manage aliases > Import.
