Abstract: 5G is being developed as a new platform for mobile networks with three main focuses: capacity enhancement, massive connectivity, and ultra-high reliability. Some of candidate technologies have emerged such as mmWave and massive MIMO. As an opposing but complementary path of wireless technology development, optical light based communications, called optical wireless communications (OWC), are being considered efficient short-range wireless communications. As a large volume of mobile traffic occur indoors, optical wireless communication is suited especially for indoor wireless communications based on light emitting diodes or other invisible lights. Optical wireless communication encompasses visible light communication (VLC), camera (or image sensor) based optical camera communication (OCC), and invisible light based optical communications such as ultraviolet and infrared. Among these sub-disciplines, optical camera communications are pretty viable and deployable in the near future, because all mobile users effectively carry OCC receivers with no additional hardware cost incurred. The recent adoption of dual camera in smartphones will open a new path for OCC in the future. This talk will provide insight into some emerging OWC technologies with some emphasis on OCC, while elaborating on some basics to OWC.
