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.

6.2 AP-02 Beacons for Indoor guidance and location

Exemplary deployment of a beacon infrastructure
The beacon attached to the asset to be tracked sends BLE signals to Smart Gateway that are installed in the building. The Gateway processes the provided data and sends it via Wi-Fi, Ethernet to Server. Here, the position is displayed on a map and motion statistics can be retrieved.
6.3 AP-03 Smart Home IoT

The Smart Gateway Working Scenario
The Smart Gateway as the brain of the smart home connects wirelessly with a wide range of smart devices and make them work together.
-
Control lights, electronics, and small appliances from anywhere.
-
Set devices to turn on and off at different times of day.
-
Receive alerts when there’s unexpected activity in your home.
-
Set connected lights to turn on and off as people come and go.
-
Monitor moisture and temperature.
