How Samsung is Leveraging vRAN to Match Traditional RAN (T-RAN) Performance

As mobile networks evolve, virtualized RAN (vRAN) and Open RAN architectures are gaining traction. Even operators who were initially sceptical are increasingly exploring and deploying these innovative solutions to meet the growing demands for flexibility, efficiency, and sustainability. Samsung, among other key players, has been at the forefront of large-scale vRAN and Open RAN rollouts across North America, Europe, and Asia.

The adoption of O-RAN-compliant, Open vRAN architectures has demonstrated the potential to deliver performance on par with—or even superior to—traditional RAN systems. While trials and commercial deployments have validated their capabilities, scaling these solutions introduces challenges, such as integration complexities, security concerns, and organizational disruptions. To address these hurdles, operators and vendors alike are focusing on building robust ecosystems, fostering collaboration, and driving continuous innovation.

As adoption expands, operators are reaping an array of benefits from vRAN and Open RAN architectures:

  • Faster site activations: Accelerated deployment timelines facilitate quicker service rollouts.
  • Enhanced resource utilization: Flexible resource sharing improves overall network efficiency.
  • Energy savings: AI-driven solutions enable dynamic power management, reducing energy consumption.
  • Operational agility: Advanced monitoring and adaptive systems boost performance and responsiveness.

Vendors and partners are tackling the complexities of scaling vRAN and Open RAN through collaborative efforts, with Samsung introducing several solutions to improve performance and address integration challenges:

  • Containerized Virtual Cell Site Router (vCSR): The integration of vCSR within the virtual Distributed Unit (vDU) minimizes hardware requirements by utilizing server processing power more efficiently.
  • Energy-saving features: AI-powered tools like Samsung’s Energy Saving Manager (ESM) enable traffic-aware adjustments, such as dynamic power amplifier (DPA) levels, sleep modes for radio units, and CPU power optimization, demonstrating significant energy reductions in large-scale deployments.
  • AI/ML-powered automation: Comprehensive platforms, such as Samsung’s CognitiV Network Operations Suite (NOS), incorporate advanced analytics and automation, enhancing network optimization, troubleshooting, and reducing total cost of ownership (TCO).

The transition to Open vRAN is not just a technological evolution but a paradigm shift in network architecture. These systems prioritize flexibility and programmability, empowering operators to achieve business objectives that extend beyond cost savings, including faster service rollouts, better customer experiences, and improved energy efficiency.

While Samsung’s contributions in this domain are notable, the larger industry trend toward open and virtualized networks reflects a collective push to shape the future of mobile connectivity. Collaboration across the ecosystem is essential to address challenges and unlock the full potential of these transformative technologies.
