The project is called City of Things and is being run in co-operation with the Flemish digital research centre iMinds, the city of Antwerp and Mobile Vikings.
Burgomaster Bart De Wever has gone on the record in the daily Gazet van Antwerpen to guarantee the privacy of the people of Antwerp: "We are just tracking the signal. We don't know whose mobile it is. The data is anonymous."
Similar projects were undertaken during the Rock Werchter concert, the Ghent Festival and Mons Cultural Capital of Europe.
