1. An apparatus for radio beacon, the apparatus comprising:

  • a transmission circuit configured to transmit a radio beacon signal;

    a detection circuit configured to detect an entrance of an obstacle into a radio space of the transmission circuit;

    a control circuit configured to control the transmission circuit based on a control value corresponding to a number of times the detection circuit detects the entrance of the obstacle in a predetermined time, wherein a radio wave field intensity and a transmission interval of the beacon signal are adjusted based on the number of times the entrance of the obstacle is detected; and

    a startup circuit confiqured to;

    start up the control circuit when the entrance of the obstacle is detected by the detection circuit, andput the control unit in a sleep state when a state in which the number of times the entrance of the obstacle is detected is 0 continues for a first given time.
