Radio device and fault position specifying method
A radio device includes a radio unit to perform modulation processing on a signal, an antenna to transmit and receive signals to and from an external unit, a cable to connect the radio unit to the antenna, a reflection time calculation unit to calculate a reflection time taken from after the transmission signal is input into a prescribed part of the radio unit until a transmission signal which is output from the radio unit is reflected on a path from the cable to the antenna is fed back to the prescribed part of the radio device, and a fault position specifying unit to specify a position candidate at which a fault occurs on the cable based on the calculated reflection time when the calculated reflection time is less than a reflection time threshold value.
