Extending End-to-End Packet Based Architecture to RAN

5G is currently being deployed across the globe with services typically introduced into urban areas and expanding coverage over time. One of the major challenges over the coming years will be enhancing 5G coverage cost-effectively. The 5G Radio Access Network (RAN) is a major contributor to overall cost with significant increase in the number of deployed cells and associated equipment as well as increased requirements for speed, reliability, and latency performance.

This paper looks at the requirement for a flexible and agile transport infrastructure that can cost-effectively support both 5G and legacy mobile network services as well as other IP-based services. The transport infrastructure needs to be open to enable network sharing, automated to enable adaptation to changing service requirements and programmable to enable support of future requirements.
