Subway wi-fi

A new subway line has opened in Milan, the M4 connecting the city airport with the city center. It’s a driverless fully automated transport system.

The active section of M4 subway in Milan.

There’s a WPA2-Personal SSID in every station, powered by Cisco APs. No wi-fi in the tunnel between stations.

As usual, quick wi-fi analysis and packet capture done with my Analiti for Android app.
