Fecha de publicación: 09/05/2016 Fuente: Wipo "IOT" The present invention relates to an IoT gateway apparatus which links a plurality of IoT devices using a low operating power. More particularly, the present invention relates to an IoT gateway apparatus which can appropriately distribute data transmission times among a plurality of internal wireless communication modules, thereby linking a plurality of various wireless communications-based IoT devices in an integrated manner while operating at a low operating power. The IoT gateway apparatus according to the present invention is an apparatus which links a plurality of IoT devices, installed in a specific area, in a composite wireless communication environment, and comprises a composite wireless communication unit (100) having a plurality of wireless communication modules, a main processor (200) controlling the wireless communication modules, a power supply unit (300) providing operating power, and an HDMI plug (400) providing power to the power supply unit (300). According to the present invention, an advantage is achieved in that the IoT gateway apparatus which performs various wireless communications with a plurality of IoT devices can operate even with very low operating power, and thus a separate power adaptor is not required, thereby providing an IoT gateway apparatus at a very low cost.
