Abstract

An apparatus and a method for reducing wireless data transmission in a personal area network is configured to generate and transmit a packet including information discriminating between a synchronous channel and a data channel. The apparatus and method discriminate between the synchronous channel and data channel when receiving a packet in order to improve data transmission performance of a human body communication system. The apparatus and the method use a transmission channel whose frequency is lower than an antenna frequency as a synchronous channel, and use a transmission channel whose frequency is higher than the antenna frequency as a data channel.
