Der Pfad von 4G zu 5G

Explore the evolution from 4G to 5G in this comprehensive conference talk from the 36C3 event. Delve into the technical aspects of air interface redesign and core network enhancements. Learn about 5G's new features, including subcarrier spacing, resource blocks, massive MIMO, and dynamic spectrum sharing. Understand the architecture of 5G networks, including NSA and SA deployments, core network elements, and interfaces. Examine the potential for increased data rates, reduced latency, and improved spectral efficiency. Gain insights into practical implementations, such as 5G on 3.5 GHz and 700 MHz bands, and antenna measurements. Discover the current state of 5G deployment and its future prospects in this German-language presentation by Peter Schmidt Heurekus.
