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
