    摘要: A communication system using a frequency determined according to information security protection or a transmission distance of a signal is provided. A local area communication requiring information security protection uses a frequency less than a predetermined frequency, and a local or wide area communication requiring no information security protection uses a frequency greater than predetermined frequency, thereby providing an effective communication environment based on information security protection, a communication distance, and communication characteristics satisfying frequency characteristics of a transmission medium, and accordingly increasing a communication field.
