Toward Satellite-Air-Ground-Ocean Optical Wireless Communication for Internet of Things

Overview

Abstract

With the advent of Internet-of-Things (IoT), the conventional radio frequency (RF) communication technology with a congested spectrum of 300 GHz cannot meet the ever-increasing demand for broadband transmission. By exploiting an unlicensed spectrum of ~ 30 PHz, optical wireless communication (OWC) technology is supposed to significantly relieve the load of RF spectrum to support the massive connectivity of IoT devices in the era of fifth-generation networks and beyond. Up to now, continuous breakthroughs in the field of free-space optical communication, visible light communication, and underwater wireless optical communication (UWOC) are laying a solid foundation for the realization of OWC across satellite-air-ground-ocean (SAGO) boundaries, which is expected to considerably accelerate the pace of realizing globally-connected IoT. In this talk, we will briefly introduce the current progress of UWOC research and development toward applications in SAGO OWC.
