Abstract:
    It is possible to realize remote control in a reflection wave transmission system, and enhance operability for a mobile apparatus having a reflector. The mobile apparatus comprises a reflector and performs reflection wave transmission by carrying data on a reflection wave for unmodulated carrier. A reflection wave reader comprises an infrared light receiving section, receives and decodes a request signal sent as an infrared remote control command, transmits it to the mobile apparatus by an ASK modulated signal and then transmits the unmodulated carrier. The mobile apparatus transmits requested data by reflection wave. The mobile apparatus can be operated from an infrared remote controller and remote control distance can be extended.
