Nokia is providing its AirScale Massive MIMO radios, baseband software, and AI-powered MantaRay network management solution. It is also supplying its Shikra mmWave radios which, are suitable for dense urban environments and also able to deliver FWA connectivity of up to 1 Gbit/s to rural or underserved communities where wired infrastructure fears to tread.
The commercial deployment completed end-to-end 5G voice and data calls with Nokia’s 5G Cloud RAN solution including its AirScale Massive MIMO radios, baseband software, and AI-powered MantaRay network management solution. Nokia’s high-performance, energy-efficient Cloud RAN architecture seamlessly integrates with all leading cloud or server infrastructures. Elisa utilized Dell XR8620 servers as well as Red Hat OpenShift, the industry’s leading hybrid cloud application platform powered by Kubernetes, to support cloud-native RAN functions across the network. By integrating with Red Hat OpenShift, service providers have the option to scale their 5G network footprint and quickly introduce new services. The deployment verified areas such as capacity, performance, features, life cycle management, automation, and energy management.
As a pioneer of 5G services in Finland, Elisa is pursuing network cloudification and extending this transformation from the network core towards the access network. Cloudification plays a key role in the scalability of network services and allows the operator to meet customers’ changing needs. With Cloud RAN Elisa is able to shift the network computing power closer to the customers, whose network usage is transforming closer to the network edge. AI-powered applications are likely to accelerate the demand for edge computing in the future.
A benefit of the early adoption of Cloud RAN is trialing the new cloud-native production model, which differs significantly from earlier models, involves a whole new ecosystem. Deploying the first commercial 5G cloud network in Europe puts Elisa in a strong position while moving towards the 6G era – which is predicted to be increasingly cloud-native. Additionally, cloudification plays a key role in Elisa’s journey towards self-driving and self-healing autonomous networks.
Nokia is helping its global customers get their Cloud RAN networks up and running much faster, removing complexity, and ensuring openness and flexibility. Nokia has already completed numerous end-to-end 5G data calls in multi-supplier setups with hardware and software from its best-in-class ecosystem of leading industry partners. It is further evidence of Nokia’s flexible anyRAN approach that provides the best choice of strategic options for communications service providers and enterprises for their RAN evolution with purpose-built, hybrid, or Cloud RAN solutions, enabling customers to monetize their networks.
Kalle Lehtinen, Chief Technology Officer, Elisa said: “This successful Cloud RAN deployment with Nokia is another important step on our cloudification which started with cloudifying the network core and edge, and now includes the radio access network. We continue to pioneer new technologies in our journey towards autonomous operations helping us to continue innovating and delivering best customer experience.”

Ericsson and Google Cloud expand partnership with Cloud RAN solution
Ericsson and Google Cloud expand partnership with Cloud RAN solution
Ericsson has announced an expansion of its successful and long-standing partnership with Google Cloud to develop an Ericsson Cloud RAN solution on Google Distributed Cloud (GDC) [1.] that offers integrated automation and orchestration and leverages AI/ML for additional communications service providers (CSP) benefits. The companies have successfully demonstrated the full implementation of the Ericsson vDU and vCU on GDC Edge and the solution is running live in the Ericsson Open Lab in Ottawa, Canada, with joint ambition for market development.
Note 1. GDC is a portfolio of fully managed hardware and software solutions which extends Google Cloud’s infrastructure and services to the edge and into your data centers.
Deploying Ericsson Cloud RAN on GDC Edge enables the delivery of a fully automated and very large-scale distributed cloud, resulting in an efficient, reliable, highly performant and secured software centric radio access network infrastructure. In this setup, the on-premises GDC Edge is managed using functions such as fleet management from the public cloud through a dedicated secure connection between on-prem hardware and the cloud, while also addressing sovereignty and privacy requirements of the CSP customers. This architecture ensures the clear path for CSPs toward the implementation of a fully hybrid cloud solution for RAN.
Cloud RAN comprises a mobile switching center, a BBU hotel and a remote radio head
C-RAN networks comprise three primary components:
- A BBU hotel. This is a centralized site that functions as a data or processing center. Individual units can stack together without direct linkage or interconnect to dynamically allocate resources based on network needs. Communication between units has high bandwidth and low latency.
- A remote radio unit (RRU) network. Also known as a remote radio head, an RRU is a traditional network that connects wireless devices to access points.
- A fronthaul or transport network. Also known as a mobile switching center, a fronthaul or transport network is the connection layer between a BBU and a set of RRUs that use optical fiber, cellular or mmWave communication.
………………………………………………………………………………………………………………………………………………………………………………………………………….
Running Ericsson Cloud RAN on GDC Edge will enable CSPs to utilize Google Cloud Vertex AI, BigQuery and other cloud services, to improve the usability of the massive data sets being provided by Cloud RAN applications. This in turn, will open a number of opportunities for CSPs to control, inspect, configure, and optimize their RAN infrastructure.
Ericsson Cloud RAN provides CSPs additional choice for creating networks based on open standards and interfaces using multiple vendors. The Ericsson Cloud RAN solution is infrastructure agnostic, allowing RAN applications to be deployed on any infrastructure chosen by the CSP. Ericsson is continuously collaborating with ecosystem partners and adapting its Cloud RAN applications to work on different infrastructures and configurations.
To further a cloud-native automation approach to network workloads, Ericsson and Google Cloud are jointly enhancing the solution through the Linux Foundation open-source project Nephio (a Kubernetes-based automation platform for deploying and managing highly distributed, interconnected workloads such as 5G network functions), where we jointly drive standardization of critical functionality.
Mårten Lerner, Head of Product Line Cloud RAN, Ericsson, says: “This partnership enables us to deepen and expand our valuable collaboration with Google Cloud, and it opens new opportunities for operators to utilize the benefits of cloud-native solutions and automation. Ericsson remains committed to ensuring the adaptability of its Cloud RAN applications on diverse cloud infrastructures, offering operators enhanced flexibility and choice in deploying Cloud RAN as well as supporting the evolving hybrid cloud architectures together with Google Cloud.”
Gabriele Di Piazza, Senior Director, Telecom Products, Google Cloud, says:
“We’re proud to enable Ericsson Cloud RAN to run on Google Distributed Cloud Edge infrastructure, which includes access to our AI/ML capabilities as well as cloud-native automations. We’re delighted to recognize Ericsson as a distinguished Google Cloud Partner and look forward to a continued strong partnership in support of our mutual customers.”

Cloud RAN with Google Distributed Cloud Edge; Strategy: host network functions of other vendors on Google Cloud
At MWC 2023 Barcelona, Google Cloud announced that they can now run the radio access network (RAN) functions as software on Google Distributed Cloud Edge, providing communications service providers (CSPs- AKA telcos) with a common and agile operating model that extends from the core of the network to the edge, for a high degree of programmability, flexibility, and low operating expenses. CSPs have already embraced open architecture, open-source software, disaggregation, automation, cloud, AI and machine learning, and new operational models, to name a few. The journey started in the last decade with Network Functions Virtualization, primarily with value added services and then deeper with core network applications, and in the past few years, that evolved into a push towards cloud-native. With significant progress in the core, the time for Cloud RAN is now, according to Google. However, whether for industry or region-specific compliance reasons, data sovereignty needs, or latency or local data-processing requirements, most of the network functions deployed in a mobile or wireline network may have to follow a hybrid deployment model where network functions are placed flexibly in a combination of both on-premises and cloud regions. RAN, which is traditionally implemented with proprietary hardware, falls into that camp as well.
In 2021,the company launched Google Distributed Cloud Edge (GDC Edge), an on-premises offering that extends a consistent operating model from our public Google Cloud regions to the customer’s premises. For CSPs, this hybrid approach makes it possible to modernize the network, while enabling easy development, fast innovation, efficient scale and operational efficiency; all while simultaneously helping to reduce technology risk and operational costs. GDC Edge became generally available in 2022.
Google Cloud does not plan to develop its own private wireless networking services to sell to enterprise customers, nor does the company plan to develop its own networking software functions, according to Gabriele Di Piazza, an executive with Google Cloud who spoke at MWC 2023 in Barcelona. Instead, Google Cloud would like to host the networking software functions of other vendors like Ericsson and Mavenir in its cloud. It would also like to resell private networking services from operators and others.
Rather than develop its own cloud native 5G SA core network or other cloud networking software (like Microsoft and AWS are doing), Google Cloud wants to “avoid partner conflict,” Di Piazza said. Google has been building its telecom cloud story around its Anthos platform. That platform is directly competing against the likes of AWS and Microsoft for telecom customers. According to a number of analysts, AWS appears to enjoy an early lead in the telecom industry – but its rivals, like Google, are looking for ways to gain a competitive advantage. One of Google’s competitive arguments is that it doesn’t have aspirations to sell network functions. Therefore, according to Di Piazza, the company can remain a trusted, unbiased partner.

Last year, the executive said that moving to a cloud-native architecture is mandatory, not optional for telcos, adding that telecom operators are facing lots of challenges right now due to declining revenue growth, exploding data consumption and increasing capital requirements for 5G. Cloud-native networks have significant challenges. For example, there is a lack of standardization among the various open-source groups and there’s fragmentation among parts of the cloud-native ecosystem, particularly among OSS vendors, cloud providers and startups.
In recent years, Google, Microsoft, Amazon, Oracle and other cloud computing service providers have been working to develop products and services that are specifically designed to allow telecom network operator’s to run their network functions inside a third-party cloud environment. For example, AT&T and Dish Network are running their 5G SA core networks on Microsoft Azure and AWS, respectively.
Matt Beal, a senior VP of software development for Oracle Communications, said his company offers both a substantial cloud computing service as well as a lengthy list of network functions. He maintains that Oracle is a better partner for telecom network operators because of it. Beal said Oracle has long offered a wide range of networking functions, from policy control to network slice management, that can be run inside its cloud or inside the cloud of other companies. He said that, because Oracle developed those functions itself, the company has more experience in running them in a cloud environment compared with a company that hasn’t done that kind of work. Beal’s inference is that network operators ought to partner with the best and most experienced companies in the market. That position runs directly counter to Google’s competitive stance on the topic. “When you know how these things work in real life … you can optimize your cloud to run these workloads,” he said.
While a number of other telecom network operators have put things like customer support or IT into the cloud, they have been reluctant to release critical network functions like policy control to a cloud service provider.

Nokia’s solutions offer network performance consistency between purpose-built AirScale baseband and Cloud RAN and secures the best possible feature performance parity, with the fastest time-to-market for cloud/hybrid networks.
Sue Rudd, Director Networks and Service Platforms at TechInsights: “As service providers evolve on the path towards disaggregated RAN, Nokia’s anyRAN offers them a solution with standard O-RAN fronthaul and 3GPP midhaul interfaces under seamless control that can operate across multiple Cloud partner data centers. Combined with acceleration from a new Layer 1 SMARTNIC and a ‘host neutral’ Container as a Service (CaaS) layer for DU and CU processing, this flexible open approach will allow operators to leverage Nokia’s powerful new ecosystem of platform and cloud partners to deliver very cost effective, high performance Cloud RAN service.”
Tommi Uitto, President of Mobile Networks at Nokia: “The strength of our industry partnerships and the launch of anyRAN unlocks more choice and higher performance in Cloud RAN for our mobile network operator and enterprise customers. Server-based Cloud RAN will have to co-exist with purpose-built RAN in the short-to-medium term which calls for performance consistency and service continuity between the two. Together with our leading industry partners, we have made huge progress towards this goal by driving consistent performance across any partner’s Cloud Infrastructure or server hardware. Our collaborative approach to Cloud RAN means we can drive efficiency, innovation, openness, and scale by jointly delivering competitive advantage to organizations embracing Cloud RAN.”
