The Launch of Open RAN: A New Era for Vodafone and Samsung
Written on
Chapter 1: Open RAN's Revolutionary Introduction in the UK
The recent inauguration of an Open RAN site in the UK by Vodafone and Samsung Networks has set a significant precedent in the telecommunications landscape. This landmark site represents the first commercial deployment of Open RAN in the UK—an achievement that stands out as a brownfield deployment and one of the earliest initiatives by a major European operator. This launch not only signifies the beginning of Open RAN's journey in the region but also serves as a crucial stepping stone for Samsung Networks in Europe.
I had the opportunity to converse via email with Andrea Dona, Vodafone's Chief Network Officer, and Thomas Riedel, Head of Samsung Networks Europe, to gain insights into this launch. The implications for Open RAN and Samsung Networks in the area are profound.
Beginning the Open RAN Transformation in the UK
The buzz surrounding Open RAN has sparked debate, with some labeling it as mere hype. To counter this perception, tangible advancements and a clear roadmap are essential. This announcement fulfills that need. As Andrea Dona stated, “This is our commitment today towards establishing a comprehensive, commercial Open RAN network in the UK,” with plans to expand to 2,500 sites by 2027, covering vast areas of the Southwest and Wales.
Contrary to many demonstrations and trials, this site is operational and managing live customer traffic, integrating seamlessly with the existing 5G infrastructure. The initial site will evolve into what Dona refers to as a “Golden Cluster” of 10–15 sites, eventually scaling to provide coverage throughout the southwest of the country. The initial applications will focus on mobile broadband, eventually expanding to Fixed Wireless Access (FWA), extensive IoT, and Mission Critical Services, all in sync with the legacy 5G network.
“Presently, we are utilizing 800 MHz and 2.1 GHz bands in Dynamic Spectrum Sharing mode, and the system is built on 3GPP Rel. 15 specifications,” noted Thomas Riedel. “By mid-2022, we will upgrade from today’s 2T2R and 4T4R configurations to 64T64R, and later transition to a Stand Alone (SA) configuration.”
Riedel emphasized the multi-vendor nature of the current setup, which includes Samsung’s vRAN and radios, Wind River’s CaaS platform, and Dell’s Intel-based servers. Later this year, Samsung’s vRAN solutions will also incorporate NEC’s 5G Massive MIMO radios. He pointed out that Vodafone's choice of Samsung’s solutions stems from their competitive edge and innovative offerings in the Open RAN space.
Moving forward, Vodafone intends to engage a system integrator to enhance the network, leveraging a diverse ecosystem of hardware and software providers.
Dispelling Misconceptions
While launching a solitary site may seem minor, it represents a significant milestone that dispels several misconceptions. Firstly, the deployment of a commercial site indicates that Open RAN has transitioned from concept to a practical reality. Secondly, the involvement of a prominent European carrier debunks the myth that Open RAN is exclusive to greenfield projects and non-prime carriers. Thirdly, it highlights that leading operators have acknowledged the complexities of adopting Open RAN and are willing to embrace new models and skill sets. For instance, Vodafone has collaborated with system integrators, initiated design centers, and acquired software development capabilities.
The coexistence of Open RAN with traditional networks has been a pressing question since discussions began. Vodafone seems to have proactively identified this challenge. Dona elaborated on Vodafone’s phased strategy of “learn and progress.” Throughout each phase—from a single site to a Golden Cluster and ultimately to a complete 2,500-site network—Vodafone plans to conduct thorough testing, analysis, and optimization. A vital criterion for learning will be the integration of both networks in a commercial environment.
Chapter 2: Samsung Networks' Strategic Entrance into Europe
Samsung Networks is closely monitoring its growth trajectory in the international market. The partnership with Vodafone, one of the largest carriers in Europe and globally, underscores the sophistication and competitiveness of its technology and solutions.
In addition to this pivotal collaboration with Vodafone, Samsung is also engaged with Deutsche Telekom in the Czech Republic and Orange in France. This trio provides access to some of the most lucrative European markets, traditionally dominated by players like Ericsson and Nokia.
Samsung enjoys a distinct advantage; it possesses both legacy and Open RAN solutions to cater to various opportunities. However, not being overly dependent on legacy systems in the European market allows it to aggressively promote Open RAN and position itself as a disruptor. Its robust financial standing and diversified business portfolio provide a significant edge in the capital-intensive 5G infrastructure sector. Furthermore, the ongoing focus on supply chain security and the geopolitical challenges faced by Chinese vendors will bolster its ambitions in the region.
As an analyst observing these developments, it will be intriguing to see how Vodafone evolves its Open RAN network and how Samsung Networks broadens its influence in Europe, leveraging the momentum of Open RAN. With the Mobile World Congress approaching, many announcements and developments on both fronts are anticipated.
