Provided is a communication system using a near field and a method thereof, which uses a conductive medium, i.e., a human body, and comprises a plurality of peripheral devices having a communication device for transmitting and receiving a predetermined data signal through the near field formed around the human body, using a carrier sense multiple access with collision detection (CSMA/CD) method, thereby solving a directional problem of an antenna when the wireless system is used and achieving miniaturization, as well as enhancing communication efficiency by using the most appropriate frequency to the human communication without collision of transmitting and receiving signals between the plurality of peripheral devices.
