The past five years of research have highlighted many potential benefits of integrating Reconfigurable Intelligent Surfaces (RISs) into wireless communication systems. The capacity and reliability can be significantly improved by controlling these surfaces to enhance the channel conditions. In this webinar, we will instead look at the dark side of the RIS technology: the harm it might cause if not properly controlled. The issues could either be accidental or intentional. One example is that another entity controls the RIS, typically to enhance the communication in an adjacent frequency band. This might inadvertently hurt the performance in your band and cause a new pilot contamination phenomenon. In the worst case, the RIS might be hijacked by someone with malicious intent, who could purposely configure it to reduce your communication performance and create unusual phenomena. How harmful might these issues be in practice?

This webinar is organized by the ITU Journal on Future and Evolving Technologies (ITU J-FET), an international journal providing complete coverage of all communications and networking paradigms, free of charge for both readers and authors. The ITU Journal considers yet-to-be-published papers addressing fundamental and applied research. Open topics for future research will be discussed. See more information on the ITU Journal webinar series and the open Calls for Papers for the upcoming ITU Journal’s issues here.

Pioneers John Elkington, Bjorn Stigson, Doug Miller, and David Suzuki fear that things may get worse before they get better on climate change issues. Only when our daily lives are disrupted and we have realized the connection between our actions and their consequences, will we finally unite on the issue. This is one of twenty interviews from the Ray Anderson Memorial Interviews as part of The Regeneration Project a joint project of Sustainability and GlobeScan.

Anne Böckler-Raettig is an Assistant Professor at the Institute of Psychology at Würzburg University. She studied in Berlin and Glasgow and completed her PhD at Radboud University in Nijmegen. After a research stay in Princeton, Anne worked as a Postdoc at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig. Anne employs methods from psychology, neuroscience, and behavioral economics to investigate the processes that underlie social understanding and social interaction. Specifically, she is interested in gaze behavior, empathy, perspective-taking, and social decision-making. More recently, Anne began to address the malleability of socio-affective and socio-cognitive capacities and interpersonal behavior by means of meditation-based trainings.
