Zusammenfassung:	The present invention relates to a first mobile device, a second mobile device, a mobile system, a method for operating the first mobile device, and a method for operating the second mobile device. The first mobile device includes: a connection terminal electrically connectable to the second mobile device; a variable impedance unit connected to the connection terminal and having an impedance depending on the power line communication (PLC) mode between the first mobile device and the second mobile device; a control unit configured to determine the PLC mode to one of PLC modes including low- and high-speed PLC modes and adjust the impedance of the variable impedance unit in accordance with the determined PLC mode; and a PLC modem configured to receive power from the second mobile device or transmit and receive data to and from the second mobile device based on the determined PLC mode. 본 개시의 기술적 사상에 따른 제1 모바일 장치, 제2 모바일 장치, 모바일 시스템, 제1 모바일 장치의 동작 방법 및 제2 모바일 장치의 동작 방법이 개시된다. 제1 모바일 장치는, 제2 모바일 장치와 전기적으로 연결 가능한 연결 단자, 연결 단자에 연결되고 제1 모바일 장치와 제2 모바일 장치 사이의 PLC(Power Line Communication) 모드에 따른 임피던스를 갖는 가변 임피던스부, PLC 모드를 저속 PLC 모드 및 고속 PLC 모드를 포함하는 복수의 PLC 모드들 중 하나로 결정하고 결정된 PLC 모드에 따라 가변 임피던스부의 임피던스를 조절하도록 구성된 제어부, 및 결정된 PLC 모드에 기초하여 제2 모바일 장치로부터 파워를 수신하거나 제2 모바일 장치와 데이터를 송수신하도록 구성된 PLC 모뎀을 포함한다.
