In 2008 the decision was made to scan for activated bluetooth devices at my home location in Linz (Austria). The location for doing this project was perfect. I was living in a narrow alley, which was used by a lot of people heading to the Hauptplatz of Linz.
So, this site will show you the environment (the location and the hardware) and some Perl code, which was used to find activated bluetooth devices in the range of coverage. In the end, there will be the results, which are quite interessting because of the environment and the timeframe the project was active.
