The response signal transmission to the omnidirectional communication repeater 300 may be performed by a communication method such as Ethernet or Wi-Fi. In one embodiment, the target device 200 may perform an initial task, such as power on, if the request signal is received.

In step 307, the omnidirectional communication repeater 300 delivers the response signal received from the target device 200 to the user device 100 using a non-directional communication method. At the time of transferring the response signal, the omnidirectional communication repeater 300 can transmit the response signal received from the target device 200 as it is, or perform appropriate processing such as packet conversion and the like. The transmission of the response signal may be performed, for example, by a communication method such as Wi-Fi. The response signal may be converted into a packet type commonly used in a non-directional communication method such as Wi-Fi and transmitted.

Step 405 is the same as step 305 described with reference to FIG. 3, and therefore, detailed description thereof will be omitted.

In step 407, the omnidirectional communication repeater 300 transmits the response signal received from the target device 200 to the user device 100 using a non-directional communication method. At the time of transferring the response signal, the omnidirectional communication repeater 300 can transmit the response signal received from the target device 200 as it is, or perform appropriate processing such as packet conversion and the like. The transmission of the response signal may be performed, for example, by a communication method such as Wi-Fi. The response signal may be transmitted in the form of, for example, a Pre Association Message (PAM) or a Wi-Fi SSID (Service Set IDentifier) broadcasting signal. The device information of the target device 200 may be transmitted in the PAM or Wi-Fi SSID broadcasting signal.
