Zusammenfassung:The present invention relates to a method of controlling digital door-lock wireless at a close range by generating DTMF signal sound through the speaker of a mobile phone. The present invention recognizes the DTMF signal sound generated in the speaker of a mobile phone through a mike in a receiving unit. In this way, the present invention is capable of wirelessly controlling a control unit such as a digital door-lock from a few centimeters to meters, thereby providing the near field wireless control method using DTMF signal sound of mobile phone to create user convenience in daily lives by using a mobile phone.
