Abstract: An electromagnetic wave propagation medium 1 extends in the propagation direction of an electromagnetic wave and has an electromagnetic wave propagation space sandwiched between conductors in the direction perpendicular to the electromagnetic wave propagation direction. A base unit 2 and multiple terminals 3 are placed on the electromagnetic wave propagation medium 1. When the position of a terminal 3 is detected, the base unit 2 transmits a position detection signal through the electromagnetic wave propagation medium 1 to the terminal 3. This position detection signal is attenuated more heavily during its propagation through the electromagnetic wave propagation medium 1 than a communication signal for use in normal communication is. The signal strength of the position detection signal drops as it moves away from the base unit 2. Hence the position of each terminal 3 can be detected based on the signal strength of the position detection signal received by each terminal 3.
