Perfect RAN or Perfect Edge: the Open RAN Dilemma Facing Operators

"The perfect distributed edge cloud infrastructure, which can support both virtualised RAN and emerging high-value use cases, does not yet exist but operators can prepare for an edge-driven RAN if they take the right steps."

Operators are starting to assess their options for migrating to vRAN or Open RAN architectures. The 'perfect' edge cloud architecture for Open RAN and next-generation industrial applications is experimental and compromises radio performance. Operators must strike a balance between having an ideal edge infrastructure and having the best radio network, while keeping commercial priorities and enterprise customers in mind.

Key questions answered in this report:

• What is the best balance between hyper-distributed edge cloud and high-performance radio for different 5G business models?

• What are the advantages of the very edge-centric architecture and what do early case studies teach us?

• What are the trade-offs that may have to be made in the RAN and how can they be mitigated?

• What technical and deployment advances are required to improve the balance for future deployments?
