PURPOSE: A method and apparatus for relaying signal by using frequency conversion is provided to secure service coverage about a plurality of frequency band without adding additional cable or antenna. CONSTITUTION: A first modem(210) transceives signal in a first frequency band among a frequency band of a signal which is inputted through a first antenna. A second modem(220) transceives signal in a second frequency band among a frequency band of a signal which is inputted through a second antenna. A conversion interface unit(230) converts signal in the first frequency band into a signal in the second frequency band. |
