  • Patent number: 9980081
    Abstract: A communication device including a communicator and a communication controller is provided. The communicator has at least two communication ranges including a short communication range and a long communication range longer than the short communication range. The communication controller permits the communicator to perform communication with a terminal present in the short communication range regardless of a priority level of the terminal. The communication controller permits the communicator to perform communication with a terminal present in the long communication range and out of the short communication range when a priority level of the terminal is higher than a predetermined priority level.
