3.Home IOT Gateway 3.1 Home IOT Gateway overall description Gateway is the core of Home IOT at home. It is the key control unit with the server platform and home IOT sensors. In some ways, Gateway entered user home is the key step of Home IOT marketing, SP could provide more value-added APP to user based on it.

It can be accessed the third APP easily. 3.1.2 Router and Network management In fact, being the core connection device of the Server and Home network device, Router and Network management is the necessary function of Gateway. 3.1.3 Sensor device inspection and dynamic management As the core device of Home IOT control unit at home, the most important function of gateway is sensor device management, including inspection and dynamic management.
