PURPOSE: A device for measuring the wireless sensitivity of a mobile communication terminal having a GPS function is provided to connect a control device with a terminal of an RF(Radio Frequency) shielded room by using an optical cable, and to emit a GPS signal while varying the position of the terminal, then to extract an SNR(Signal to Noise Ratio) for each direction, thereby exactly measuring GPS wireless performance in a normal operational state. CONSTITUTION: Optical cable adapters(202,203) are used to connect an optical cable(201) with a terminal(103) and a computer(104). An RF shielded room includes an antenna(ANT) for wirelessly transmitting a GPS signal and a CDMA signal generated from a GPS signal generator(101) and a CDMA test set(102) respectively to the terminal(103). The GPS signal generator(101), the CDMA test set(102), and the terminal(103) are controlled by a computer(104) located outside the RF shielded room.
