New Whitepaper:  Multi-Layer and Cloud-Ready Radio Evolution Towards 5G

As we continue our series of blogs on Nokia AirScale Radio Access, we now take a look at what AirScale Cloud RAN can do for operators.
In recent years, the core network has been moved aggressively into the cloud, bringing operators new flexibility and lower costs. Today, I think it is widely accepted across the industry that the same evolution must be applied to the Radio Access Network (RAN). Making the RAN multi-layered and cloud-based will be essential in order to meet the demands of 5G services cost-effectively and flexibly.

But how can the RAN be transformed? And can it be done in a way that leverages the existing legacy infrastructure?

Nokia AirScale Cloud RAN

It’s precisely this challenge that Nokia’s AirScale Cloud RAN has been designed to meet. With its unique multi-layer approach, AirScale Cloud RAN supports distributed and centralized deployments, or even a combination of both. It does this using multiple fronthaul types, including Ethernet.

Cloud RAN is part of AirScale Radio Access, offering the type of scalability and flexibility that future 5G networks will need, supported by continuous and rapid deployment of software upgrades.

Nokia AirScale Cloud Base Station Server - a virtual base station - runs on Nokia’s powerful AirFrame Data Center platform, designed to meet stringent radio access capacity, performance and latency requirements.

Our efforts in Cloud RAN are certainly getting noticed. Current Analysis’ recent report analyzes cloud RAN solutions.

Ed Gubbins Senior Analyst in Wireless Infrastructure at Current Analysis, writes:

“Nokia has been a leader in driving and commercializing Cloud RAN innovations. The timely launches of Nokia’s AirScale and AirFrame solutions give it an edge in this space, and its proactive moves to develop Mobile Edge Computing technology - earlier than most rivals - give it added credibility.”

You can read more about our AirScale Cloud RAN solution and its benefits in this Executive Summary.

White Paper gives more insight


A multi-layer RAN that divides the baseband processing architecture into real time (RT) and non-real time (NRT) functions will meet the need for multi-connectivity and 5G networks. It will also support the evolution of today’s distributed and centralized RAN and RAN architectures.
By migrating to such a multi-layer Cloud RAN with new functionalities, you can re-use your existing distributed or centralized radio architectures and your existing transport assets more efficiently, enabling a smooth evolution to a cloud optimized RAN, ready for 5G and the Internet of Things.
