Optical wireless communications technologies for the internet of things

by Dominic O’Brien, Professor of Engineering Science, Department of Engineering Science, University of Oxford

The Internet of Things (IoT) presents a wide range of implementation challenges, including ensuring security, lowering energy consumption, and providing reliable communications. Optical Wireless Communications (OWC) and LiFi can assist in achieving this, and provide secure contained communications channels, energy that can be harvested by IoT nodes, and critically; new regions of the electromagnetic spectrum to alleviate the demands on the congested RF spectrum.

In this information age, communication is central to our societies but it is taking a toll on the earth. As reported by Time Magazine, by 2013, we were already using 50% more energy moving bytes than moving airplanes around the world. Our societies face a major challenge: How can we satisfy our ever-growing demand for communication but in a sustainable manner?
