Abstract: A communication device includes: a distance information acquisition unit configured to acquire distance information indicating a distance to a communication target; a setting information acquisition unit configured to acquire setting information including a communication distance; and a communication unit configured to communicate with the communication target. The distance information acquisition unit acquires the distance information after the communication unit establishes connection with the communication target. The communication unit cuts the connection with the communication target when the distance information does not satisfy the communication distance included in the setting information.

Abstract: A wireless communication system includes a reception terminal used by a user, and a transmission terminal that transmits data to the reception terminal in a wireless communication method having directivity. The transmission terminal notifies of a directional area connectable by the wireless communication method when a connection authentication in the wireless communication method with the reception terminal is successful. The transmission terminal does not notify of the directional area connectable by the wireless communication method when the connection authentication with the reception terminal is failed.
