Abstract
A communication device (201) receives internal electric waves (302) emitted toward inside a vehicle (100) by an internal communicator (102) mounted in the vehicle (100), and receives external electric waves (303) emitted toward outside the vehicle (100) by an external communicator (103) mounted in the vehicle (100). The communication device (201) determines whether the communication device (201) is inside the vehicle (100) or outside the vehicle (100), from a reception intensity of the received internal electric waves (302) and from a reception intensity of the received external electric waves (303).
