Optical Camera Communications (OCC) Technology in Visible Light Communication

Visible light communication is a technology which uses LED light signals blinking at a high frequency to transmit data. The high blinking frequency allows the light signals to be undetectable to the human eye, enabling LED light to serve the purpose of data transmission in addition to illumination.

The Optical Camera Communications Technology developed by ITRI uses the camera function embedded in smart phones as a receiver. Hence, visible light communication is available right after a software upgrade, increasing consumers’ willingness to adopt it. In recent years, companies in the wireless communication industry have been conducting 5G experiments at a high–frequency band. Visible light communication makes use of an ultra–high frequency band of 430 to 770 THz, enabling extremely fast data transmission. Theoretically, it can achieve a communication volume of several terabytes per second.

This technology has been applied to self-service stores. It won a 2016 Red Dot Communication Design Award and a 2016 ICT Month Innovative Elite Award.
