Abstract
In a device network system, system recognition processing that identifies a device connected by a wired line is performed using a low-frequency signal of a frequency lower than a first frequency used in communication, and a signal of the first frequency is used to transmit predetermined instruction information. The low-frequency signal includes first information for connection to a network, and identification information of a group to which a device to which the low-frequency signal is transmitted belongs. The predetermined instruction information is transmitted to a device that has received the low-frequency signal, has registered the first information, and has connected to the network, and for which participation in the network has been approved.
