1. A communication device comprising:
processing circuitry
to receive internal electric waves emitted toward inside a vehicle by an internal communicator mounted in the vehicle, and to receive external electric waves emitted toward outside the vehicle by an external communicator mounted in the vehicle, and
to determine whether a position of the communication device is inside the vehicle or outside the vehicle, from a reception intensity of the received internal electric waves and from a reception intensity of the received external electric waves,
wherein the processing circuitry
transmits information periodically toward a device on a periphery,
stops transmission of the information when the position of the communication device is determined to be inside the vehicle, and
acquires open/close information indicating whether a door of the vehicle is open or closed,
wherein when the position of the communication device is determined to be inside the vehicle and when the acquired open/close information indicates that the door is closed, the processing circuitry executes control to stop transmission of the information.
