APPARATUS AND METHOD FOR COMMUNICATION LINK KEEPING VISIBILITY USING VISIBLE LIGHT COMMUNICATION

摘要

A communication link apparatus capable of maintaining visibility in the visible light communication and a method thereof are provided to enable a user to visually confirm the location and range of the visible light, thereby arranging a communication link. A transmitter transmits a frame for forming a communication link before data transmission to a receiver. The receiver transmits a response frame to the frame. The transmitter transmits a data frame including information to the receiver. The receiver transmits an Ack frame in response to the data frame to the transmitter. The transmitter transmits a termination frame to the receiver. The receiver transmits a termination Ack frame to the transmitter in response to the termination frame. The transmitter and receiver transmit visible sequences in the time slot when each frame for communication is not transmitted.
