PROBLEM TO BE SOLVED: To enhance the reliability of one to multi communication by surely stopping a burst signal sent from a wireless device whose transmission/reception stop control is faulty. SOLUTION: A transmission ON/OFF control section 2141 generates a burst ON/OFF control timing on the basis of a detection result of an IF signal detector 2130 and applies ON/OFF control to a transmission ON/OFF switch 2123 according to the timing. An RF signal detector 2131 detects the output of an RF amplifier 2124 for that time, a transmission state fault discrimination section 2142 monitors the time for a transmission ON state from the detection result, a forced transmission stop control section 2143 stops supply of power to the RF amplifier 2124 when the transmission ON state consecutive time exceeds a preset threshold value so as to forcibly stop the transmission of a main signal from an ODU 210 to a base station 100. |
