5G

5G is the fifth-generation of cellular network technology. Each of the generations provides much broader bandwidth, lower latencies, and smaller physical footprint, etc. 5G technology provides innovations like virtualization, network slicing, beam-steering & beam-forming (with AAU), etc. User-plane and data-plane separated, latency reduces (up to 3ms) and more. I will share my notes by topics and I'll update the content over time.

I will share my notes about 5G Core Network by the given topic flow below.
