Application List

6.1 AP-01 Monitor Shopping and Street Activity

The smart gateway can be used to detect iPhone and Android devices, which can be detected without the need of being connected to an specific Access Point, enabling the detection of any smartphone, laptop or handsfree device which comes into the coverage area of this smart gateway and in general any device which works with Wi-Fi or Bluetooth interfaces. Users have to do nothing to be detected as the Wi-Fi and Bluetooth radios integrated in their smartphones.
