    • PURPOSE: A device for detecting abnormal vibration of a repeater inside a wireless communication system is provided to detect a vibration phenomenon of which the power level is not extremely high by comparing a reference voltage. CONSTITUTION: A signal extracting unit(200) connected to a reverse link of a repeater(100) detects a signal of a predetermined channel inside the reverse link. A signal power detecting unit(300) converts the power of the signal extracted in the signal extracting unit(200) into voltages. A circuit interface comparing unit(400) compares an output voltage of the signal power detecting unit(300) with a predetermined reference voltage. A digital logic unit(500) combines result values consecutively outputted from the circuit interface comparing unit(400) to decide abnormal vibration.

    • PURPOSE: A method and an apparatus for monitoring a wireless signal in a wireless communication system are provided to easily measure a signal waveform and a power about an input signal and an output signal of a transceiver without a measurement equipment with a high price. CONSTITUTION: A signal extracting unit(10) extracts a signal of a band which a user wishes for monitoring among signals from a base station system. A signal power measuring unit(20) detects a power level from the signal extracted by the signal extracting unit(10). An A/D converting unit(30) converts an analog signal outputted from the signal power measuring unit(20) into a digital signal. A key input unit(40) inputs the band of the signal which the user wishes for monitoring and sets a desired processing method. A signal processing control unit(50) processes the signal outputted from the A/D converting unit(30) according to the signal band and the processing method inputted through the key input unit(40). A display unit(60) displays contents processed in the signal processing control unit(50). A communication unit(70) transmits the monitored result of the signal band to an other system using a communication line.
