The present invention provides a communication system, for communicating between a remote controller and equipment through infrared rays and wireless. A frequency for wireless communication is appointed to equipment through infrared ray communication from the remote controller, and a feedback signal is sent to the remote controller through the wireless with the appointed frequency from the equipment. The infrared ray is directional, thus there will not be call from the remote controller to non-appointed equipment. in addition, the equipment sends the feedback signal with the appointed frequency through the wireless to the remote controller, thereby it is capable of reducing a possibility of occurring an interference to the wireless communication. |
