Abstract: The IoT (Internet-of-Things) is a modern-day buzzword with lofty expectations to have a profound impact on society. However, what is it, how will we use it and what will that impact be? Is it exciting or will it be frightening? Will it be helpful? Who will be the winners and who will be the losers? These are important questions, especially when you consider that IoT may have as great an impact on society as computers and the Internet have had. Maybe even more. In the Internet of Things, connectivity to people and things comes from Earth-bound wired and wireless networks. However, fewer technologists know about the evolving Internet-of-Space (IoS), where connectivity comes from space-based satellites and—in the near future—lower altitude airborne platforms based on drones and even balloons.
Furthermore, demands by the communications industry for greater and greater bandwidth push the capability of conventional wireless technology. Optical systems and networks offer a far greater bandwidth. This means new devices and systems have to be developed. Semiconductor Light Emitting Diode (LED) is considered the future primary lighting source for buildings, automobiles and aircrafts. LED provides higher energy efficiency compared to incandescent and fluorescent light sources and it is already playing a major role in the global reduction of carbon dioxide emissions, because of the significant energy savings. Lasers are also under investigation for similar applications. These core devices have the potential to revolutionize how we use light, including not only for illumination, but as well; for communications, sensing, navigation, positioning, surveillance, and imaging.
Visible light communication (VLC) technology is one of the advanced optical wireless communication technologies. Indoor networking and location-based services are the only applications that are quite penetrated in the market . Products for other applications are expected to hit the market soon. Prototypes for underwater communication are available at present. Japan sampled the intelligent traffic management systems with VLC technology and expected to bring it in the mainstream. VLC can be implemented as a complement to the existing wireless networking technologies like Wi-Fi and 5G etc. VLC is expected to penetrate in the future applications like Machine-to-Machine (M2M) communications, smart cities, wireless sensor networks, ubiquitous computing etc. in the next five years. In 2010, VLC systems were able to achieve data rates of 500 Mbps for a short range of 5 meter. With the ongoing R&D, some research institutes were able to achieve transmission rates of ~ 1 Gbps for longer-range communications. Research centers and companies are looking forward to achieve Gigabit network with VLC technology. See Figure-1 below.
This paper introduces a novel idea called; “Internet-of-Light”. It can address the needs of both IoT and IoS. It is very secure at physical layer and can be applied to many real and necessary service areas; e.g., manufacturing, transportation, health, communications, sensing and navigation, to name a few, that are all essential technologies for our nation. The most compelling story of how
Internet-of-Light will transform our world is the one still being written: the future of lighting, communications, sensing and the birth of a new enterprise lighting network.
Keywords: IR, FSO, VLC, Smart Homes, Positioning by Light and Smart Cities, IoT, IoS.

Biography: Dr. Mohsen Kavehrad is the President of Center for Research in Knowledge Communication (CRKC) and retired W. L. Weiss Chair Professor of Electrical Engineering, Pennsylvania State University. He received his Ph.D. degree in Electrical Engineering from Polytechnic Institute of New York University (formerly; Brooklyn Polytechnic Institute) in 1977. Between 1978 and 1981, he worked for Fairchild Industries (Space Communications Division) and GTE (Satellite Corp. and Labs.). He then joined Bell Laboratories where he worked on communications and networking research problems. After the breakup of the Bell System, he joined the Department of Electrical Engineering at University of Ottawa, as a Full Professor in March 1989. He was also the Director of Photonic Networks and Systems Thrust and a project leader in the Telecommunications Research Institute of Ontario (TRIO) and the Director of Ottawa-Carleton Communications Center for Research (OCCCR). He was an academic visitor (senior technical consultant) at NTT Laboratories, Japan, in summer 1991. He spent a six months sabbatical term as an academic visitor (senior technical consultant) at NORTEL, Ottawa, in 1996. In January 1997, he joined the Department of Electrical Engineering, The Pennsylvania State University as the W. L. Weiss (AMERITECH) Endowed Chair Professor of Electrical Engineering. In August 1997 he was appointed as the founding Director of Center for Information and Communications Technology Research (CICTR). During 1997-1998 he was also the CTO and a Vice President at Tele-Beam Inc., State College, PA. He spent a six months sabbatical term as an academic visitor (senior technical consultant) at AT&T Shannon Research Labs., Florham Park, New Jersey, in 2004. He has also served as a consultant to a score of major corporations and government agencies.
Dr. Kavehrad’s research contributions have been in the fields of: Satellite communications, Fixed radio communications, Portable and Mobile radio communications, Atmospheric Laser communications, Fiber optic communications and fiber optic networks. His current research interests are in the areas of technologies, systems, and network architectures that enable the vision of the information age; e.g.,Broadband Wireline/Wireless Communications Networked Systems and Optical Communications Networked Systems. Since the start of his academic career, these research topics and others have led to significant graduate research.
