Implementation challenges and opportunities in beyond-5G and 6G communication
As 5G NR is being rolled out, research effort is being focused on the evolution of what is to come in the post-5G era. In order to meet the diverse requirements of future wireless communication in terms of increased capacity and reduced latency, technologies such as distributed massive MIMO, sub-mm-wave and terahertz spectrum become technology components of interest. Furthermore, to meet the demands on connectivity anywhere anytime, non-terrestrial satellite networks will be needed, which brings about challenges both in terms of implementation as well as deployment. Finally, scaling up massive IoT, energy harvesting and SWIPT is foreseen to become important enablers when deploying a large amount of small, low-power radios. In this keynote, we will discuss some of the important opportunities these technologies bring and the challenges faced by the microwave and wireless communication communities.
