Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A network providing device includes at least one transceiver, and at least one processor operatively coupled with the at least one transceiver. The at least one processor is configured to acquire a measurement result of a signal transmitted by a first cellular network, and transmit, to a router, a control message for setting a router to access a network identified on the basis of the measurement result. The network comprises at least one of the first cellular network and a second cellular network.

Abstract: The present disclosure relates to a method for blocking the connection of an electronic device inside a wireless intrusion prevention system, the method comprising the steps of: successively monitoring wireless frames in a plurality of channels through a first communication module; generating a first blocking message on the basis of at least one wireless frame received as a result of the monitoring and generating a second blocking message on the basis of a first wireless frame, to which a predetermined wireless network technology has been applied, among the at least one wireless frame; and transmitting at least one of the first and second blocking messages through a second communication module. The present disclosure is not limited to the above embodiment, and other embodiments are also possible.

Abstract: An operating method for a location estimation apparatus communicating with an access point (AP) in a wireless communication system according to an embodiment of the present invention comprises the steps of: receiving, from a second AP, a first received signal strength indicator (RSSI) signal having been measured at a first AP, and generating a first RSSI vector corresponding to the first RSSI signal; calculating a path loss exponent, using the distance between the first AP and the second AP and the first RSSI vector, and generating a second RSSI vector of each of multiple sub-areas divided from an entire area, using the path loss exponent; and generating a radio map of the entire area, using the first RSSI vector and the second RSSI vector.
