    Abstract: An electronic device including a first memory configured to store authorization information; a first processor configured to access the first memory; a second memory; and a second processor configured to access the second memory. The first processor is configured to check state information related to a battery state of the electronic device while the electronic device is in a first state; if the state information satisfies a first specified condition, provide authorization information to an external device in the first state so that the external device performs authorization using the authorization information; and if the state information satisfies a second specified condition, copy the authorization information into the second memory in the first state and convert the electronic device to a second state in which power consumption thereof is less than that in the first state. The second processor is configured to provide the authorization information to the external device in the second state so that the external device performs authorization using the authorization information.

    Abstract: An electronic device may include thin antennas disposed proximate a rear or front surface. An antenna structure may be disposed at a portion of a first surface or a second surface of a non-metal structure within the device, and is electrically connected to the metal structure. The antenna structure may comprise: a first bonding layer attached to a portion of the first surface or the second surface, where an opening is formed in the first bonding layer at a location of the metal structure; a antenna element pattern arranged on the first bonding layer and electrically connected to the metal structure through the opening; a second bonding layer arranged on the antenna element pattern; and an insulation layer arranged on the second bonding layer.

    Abstract: The present disclosure relates to a 5G or pre-5G communication system to be provided to support a higher data transfer rate beyond a 4G communication system such as LTE. The present invention relates to a method and device which detects performance degradation of a cell in relation to wireless communication and analyzes the degraded performance. More specifically, an analysis device for analyzing performance degradation of a cell in a wireless communication system according to an embodiment of the present invention comprises: a data retrieval unit for acquiring, from a cell, first data measured through wireless communication of the cell, a compression/decompression unit for acquiring second data by applying the first data to a particular model in which reference data related to an indicator for the performance of wireless communication is set, and a performance degradation determination unit for determining whether the performance of the cell is degraded, based on third data derived from the difference between the first data and the second data, wherein the compression/decompression unit acquires the second data by compressing and decompressing the first data according to the reference data.

    Abstract: An electronic device including a shielding structure is provided. The electronic device includes a housing, a first board disposed in an inner space of the housing and including a first electrical element and a first ground layer, a second board disposed in the inner space to be spaced apart from the first board and including a second electrical element, and an interposer disposed between the first board and the second board so as to electrically connect the first board and the second board to each other. The second board includes a first surface facing the first board, a second surface facing away from the first surface, insulating layers disposed between the first surface and the second surface, first slits formed at a predetermined interval in a first conductive area disposed in a first insulating layer among the insulating layers, and second slits formed at a predetermined interval in a second conductive area disposed in a second insulating layer between the first insulating layer and the second surface. The first slits are disposed at a position where the plurality of first slits do not overlap the plurality of second slits in case the second board is viewed from above.
