Title: Towards Truly Sustainable Wireless Communication Systems
Marcos Katz, University of Oulu, Finland
The current development of 6G is focused on creating communication and computing systems with unprecedented performance levels. Moreover, the development is also considering, more than ever before, the costs associated with such systems, in terms of consumption of resources. Sustainability is one key aspect of 6G systems, and in this presentation 6G sustainability will be approached from a wide perspective, taking into account resource utilization well beyond the conventional energy cases. This will allow minimizing the overall resource consumption and therefore, developing a truly sustainable system. A holistic approach to sustainability will be discussed, considering measures to improve sustainability at different stages of a 6G system, from design to end-of-life. Finally, a concrete example of the holistic approach towards truly sustainable 6G systems will be presented and discussed.
