In this lecture, Dominic O'Brien introduces the field, the challenges, and the promise for the future of this area of research. The demand for wireless communications is growing exponentially, and the radio spectrum required to meet this demand is increasingly crowded, leading to predictions of a ‘spectrum crunch’. Using light for wireless transmission is an attractive alternative. Optical wireless can offer access to almost unlimited spectrum, albeit with many implementation challenges.

In this talk, Justin Coon explores the issue of complexity in the IoT from a fundamental perspective and provide some insight into what this means for practical deployments in the future. The evolution of wireless communication technology over the past two decades has led to severe engineering challenges concerning interference and network densi cation. As we begin to embrace the Internet of Things (IoT) paradigm, these challenges are sure to grow. Indeed, it is predicted that connection densities will surpass one million per square kilometre in the near future, largely owing to the deployment of IoT networks and services. Yet, relatively little has been done to quantify the growing complexity of these networks, and the subsequent implications that this growth will have on network performance.
