Abstract

A system and a method for relaying communications with a designated network are provided. The first electronic device for relaying communication with the designated network includes a first communication circuit for receiving a first signal in a first frequency band from the designated network, a transceiver for receiving the first signal in the first frequency band from the first communication circuit, and a second communication circuit which includes a second duplexer for receiving, from the transceiver, a first signal in a second frequency band, which is generated from the first signal in the first frequency band, and transmits the first signal in the second frequency band to a second electronic device. The first signal in the second frequency band is provided to a third duplexer corresponding to a third frequency band included in the second electronic device. A partial frequency region in the second frequency band overlaps with the third frequency band.
