Assignee: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A communication system, comprising:
a processor;
a communication device being controlled by the processor, including an electrode, an antenna, an HBC signal processing circuit, and a wireless communication signal processing circuit, and receiving a communication signal via any one of the electrode and the antenna; and
a service module configured to use the communication signal;
wherein the communication device operates in one of a wireless communication mode or an HBC communication mode based on an amount of change from an initial value of a capacitance of the electrode; and
wherein to determine whether to operate in the one of the wireless communication mode or the HBC communication mode, the communication device
measures the capacitance of the electrode,
compares the amount of change from the initial value of the measured capacitance with a threshold,
operates in the wireless communication mode when the amount of change is less than the threshold, and
operates in the HBC communication mode when the amount of change is greater than or equal to the threshold.
