Upon determination that a mobile device has continued to be present within a first transmission area for a predetermined time or over, the control device lowers first transmitter power output of a first electromagnetic wave to be transmitted from the communication section to second transmitter power output of the first electromagnetic wave so that the first transmission area is narrowed to a second transmission area until no more response is received from the mobile device. Then, the communication section not only transmits the first electromagnetic wave having the second transmitter power output and generating the second transmission area but also transmits, with a second cyclic period longer than the first cyclic period, a second electromagnetic wave, the second electromagnetic wave has the first transmitter power output and generates the first transmission area which is not narrowed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Smart entry system","description":"A smart entry system comprises a communication section and a control device.
