SCF Technology & 5G: Past, Present & Future
TECH & 5G Working Group
• Very active working group with several active Operators & Vendors and is chaired by Prabhakar Chitrapu (AT&T) and Neeraj Gupta (NEC).
• Over the years, the WG produced a voluminous set of white papers in the areas of Architectures, Radio Technologies, Interfaces, Virtualization, SON, Security etc. Additionally, the WG also drove “standardization” of Small Cell Interfaces & APIs.
• Current Work Focus:
• HetNet SON, Orchestration & Automation,
• Shared Spectrum Techniques for Multi-Operator/Neutral-Host Enablement,
• Small Cells for 5G-Use Case Categories,
• Edge Computing & Network Slicing…
• A little bit of history….
Snapshot of SCF TECH Contributions
