PURPOSE: A repeater and method capable of detecting a shadow area in a radio communication system are provided which is provided with a multimedia signal having a function of detecting the shadow area to detect the shadow area in a cell area. CONSTITUTION: A repeater having a function of detecting a shadow area in a radio communication system includes the first radio frequency processor(210), a repeater modem unit(230) and the second radio frequency processor(220). The first radio frequency processor transmits a radio frequency signal sent from a base station(100) to the modem unit and delivers a signal transmitted from the modem unit to the base station. The repeater modem unit monitors, converts and multiplexes a shadow area detection signal sent from the outside to cancel the shadow area. The second radio frequency processor transmits a radio frequency signal sent from a subscriber unit(300) to the modem unit and delivers a signal transmitted from the modem unit to the subscriber unit.
