Telecom Network Evolution: 2G-to-6G Technologies, Architecture, and Key Concepts

Get a comprehensive exploration of mobile network evolution, comparing architectural transformations from 2G to 6G. Explore the core components of 4G and 5G networks, including RAN architectures, core network functions (AMF, SMF, and UPF), and transport network design principles. Discover the essentials of critical physical layer technologies such as spectrum allocation, frame structures, OFDMA, MIMO, and carrier aggregation across 4G and 5G systems. Along the way, learn about signaling procedures, including network registration, mobility management, and end-to-end session establishment in both network generations. By the end of this course, you’ll be prepared to evaluate next-generation technologies like NFV, cloud-native architectures, and network slicing in 5G, while also exploring their evolution into 6G networks.
