Abstract: A first device of a wireless synchronization system includes: a first sensor for measuring a physical quantity related to power consumed by wireless communication process of a first communication circuit; and a first control circuit outputting a first synchronization signal at a timing that the magnitude relation between the physical quantity measured by the first sensor with respect to one of transmitting process and receiving process in the wireless communication process and a predetermined threshold value changes. A second device includes a second control circuit outputting a second synchronization signal at a timing that the magnitude relation between the physical quantity measured by the second sensor with respect to the other one of the transmitting and receiving processes in the wireless communication process in a second communication circuit and a predetermined threshold value changes.

Abstract: When a state of a radio communication device corresponds to a predetermined state, a communication control unit operates in the first mode to communicate according to the BLE standard, while when the radio communication device does not receive connect request packets, the communication control unit operates in the second mode to communicate. A rewrite switching unit switches to a rewritable state when the communication control unit operates in the first mode and to a rewriting prohibited state when the communication control unit operates in the second mode. The first mode is a mode for updating. In the first mode, the communication control unit transmits a notification for limiting the communication to the updating in an establishment process of the communication. The second mode is a mode for performing processing other than the updating. In the second mode, the communication control unit does not transmit the notification.

Abstract: A wireless communication apparatus includes a communication controller and an identification information setup portion. The communication controller establishes first communication, namely, communication with a first wireless communication apparatus having identification information already set and receives first information, namely, information to settle the identification information to be set, from the first wireless communication apparatus. The identification information setup portion sets the identification information for the wireless communication apparatus based on the first information. After setting the identification information, the communication controller establishes second communication, namely, communication with a second wireless communication apparatus having identification information not set yet, and transmits second information, namely, information to settle the identification information to be set for the second wireless communication apparatus, to the second wireless communication apparatus. The communication controller transmits the second information to one second wireless communication apparatus and subsequently does not transmit the second information.

Abstract: Provided is a technology for a technology for easily inhibiting a wireless signal from being spoofed. A wireless communication system includes a beacon device and an information processing terminal. The beacon device includes a first communication circuit for transmitting a beacon signal to the information processing terminal in accordance with a predetermined transmission interval pattern. The information processing terminal includes a second communication circuit, a first storage device, and a control device. The second communication circuit receives the beacon signal from the beacon device. The first storage device stores the predetermined transmission interval pattern. The control device authenticates the beacon device by comparing a reception interval pattern of the beacon signal received by the second communication circuit with the predetermined transmission interval pattern stored in the first storage device.
