Patent attributes
An internet of things (IoT) system and a backup channel utilization method thereof are provided. A first network hub device is connected to at least one first IoT device, and a second network hub device is connected to at least one second IoT device. An access point is connected to the first network hub device and the second network hub device. An IoT service server is connected to the first network hub device and the second network hub device through the access point. The first network hub device establishes a connection with the second network hub device through a backup frequency channel in response to that a connection between the first network hub device and the access point is abnormal, and the first IoT device reports IoT data to the IoT service server through the backup frequency channel.
