At the reception of Microsoft and Munich Security Conference (MSC) in Berlin, the 5G expansion was the focus of discussions with i.a. Dr. Norbert Röttgen MdB; Siim Alatalu (Information System Authority, Estonia), Thomas Bihlmayer (eco), Kruthika Anastasia Bala (Eeurasia Group), Elly van den Heuvel (Cyber Security Council, Netherlands) and Sven Sakkov (ICDS, Estonia). The topic will keep us busy for a long time. We need new approaches to adapt the inevitable interdependencies we have to national and European requirements. Basically, we need clear international rules to ensure transparency in software and hardware.
