Abstract:
1. A radio repeating system comprising: a first radio terminal for transmission, having a half-duplex communication function; a second radio terminal for reception, having a half-duplex communication function; a radio repeater to receive a signal transmitted from the first radio terminal and transmit the signal to the second radio terminal by relay transmission; and a controller to control the radio repeater, wherein the controller includes: a terminal signal determiner to detect a signal from the first radio terminal to determine whether the first radio terminal is in a transmission halt mode or a transmission performing mode; a first counter to start counting when the terminal signal determiner determines that the first radio terminal is in the transmission halt mode and continue counting a predetermined first time; and a second counter to start counting when the terminal signal determiner determines that the first radio terminal is in the transmission performing mode and continue counting a predetermined second time, wherein the controller halts a wireless relay operation of the radio repeater when the terminal signal determiner determines that the first radio terminal is in the transmission halt mode while the second timer is operating, or when the first timer finishes counting of the first time.
