Many topics are studied within the 6G research community, from hardware design to algorithms, protocols, and services.
Erik G. Larsson and Emil Björnson recently attended the ELLIIT 6G Symposium in Lund, Sweden. In this episode, they discuss ten things that they learned from listening to the keynote speeches.
The topics span from integrated sensing, positioning, and localization via machine-learning applications in communications to fundamental communication theory, such as circuits for universal channel decoding and jamming protection.
The expected 6G spectrum ranges, energy efficiency in base stations, and new use cases for electromagnetic materials are also covered.
