    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.

    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 translation: 当无线电通信设备的状态对应于预定状态时，通信控制单元按照BLE标准在第一模式下进行通信，而当无线通信设备没有接收到连接请求分组时，通信控制单元在 第二种沟通模式。 当通信控制单元在第二模式下操作时，当通信控制单元在第一模式下操作时，重写切换单元切换到可重写状态，并切换到重写禁止状态。 第一种模式是更新模式。 在第一模式中，通信控制单元在通信的建立处理中发送用于将通信限制到更新的通知。 第二模式是用于执行除更新之外的处理的模式。 在第二模式中，通信控制单元不发送通知。
