In a significant leap for the telecommunications industry, StarHub has successfully implemented Singapore’s first Open Radio Access Network (Open RAN) call on its 5G network in collaboration with NTT DOCOMO. This monumental achievement marks a pivotal milestone for both companies and sets a new benchmark in the global telecom landscape. By adopting Open RAN architecture, StarHub aims to transform network infrastructure, offering greater customization, flexibility, and cost-efficiency compared to traditional Radio Access Networks.
Benefits of Open RAN Over Traditional Networks
Flexible and Customizable Network Components
Open RAN architecture allows telecom operators to decouple radios and base stations, tailoring these components to enterprise-specific needs. Traditional Radio Access Networks usually tie operators to a single vendor, limiting flexibility in component selection and network optimization. However, Open RAN uses standardized, open interfaces, enabling equipment from various vendors to work together seamlessly. This vendor-agnostic approach permits mobile network operators to choose superior components from different providers, fostering competitiveness and innovation.
The ability to select and integrate components from multiple vendors not only enhances network performance but also drives down costs. Telecom operators can avoid being locked into long-term contracts with a single supplier, thereby negotiating better deals and reducing operational expenses. As a result, the operational flexibility offered by Open RAN allows for continuous technological evolution and ensures that networks are always at the cutting edge of development. This move towards a more modular and adaptable network framework is a game-changer for the industry, facilitating quicker and more efficient upgrades and expansions.
RAN Intelligent Controllers for Optimization
Another significant advantage of Open RAN is the implementation of RAN Intelligent Controllers (RICs), which provide advanced network performance optimization. These controllers utilize artificial intelligence and machine learning algorithms to monitor and adjust network parameters in real time. The inclusion of RICs allows for automated management and fine-tuning of network resources, ensuring optimal performance under varying conditions. Traditional networks often require manual adjustments and are slower to respond to changing demands.
By automating network management, RICs minimize human error and enhance the reliability and efficiency of the telecom infrastructure. This technology is particularly vital in managing the complex and dynamic needs of modern 5G networks, which support a wide range of applications from consumer mobile services to industrial IoT deployments. The enhanced optimization capabilities provided by RICs enable operators to deliver superior service quality and meet the growing expectations of end-users. The integration of RICs within Open RAN frameworks underscores the commitment to innovation and efficiency, driving the next wave of telecom advancements.
Rigorous Collaboration for Robust Implementation
Comprehensive Field Trials and Validations
The successful deployment of Open RAN by StarHub and NTT DOCOMO involved rigorous field trials and validation processes. Collaborating with Keysight Technologies and Fujitsu, the companies conducted extensive tests using Keysight’s UeSIM UE Emulation RAN Solutions. These trials ensured that the Open RAN’s performance met high standards of reliability and implementation readiness. Key performance metrics such as downlink and uplink throughput, as well as latency, were evaluated to ensure the network could handle real-world demands effectively.
Specifically, the trials demonstrated impressive network capabilities, achieving a downlink throughput of up to 1.295Gbps, uplink throughput of 73.5Mbps, and an average latency of 15ms. These metrics not only highlight the efficiency and robustness of the Open RAN architecture but also validate its readiness for commercial deployment. Ensuring compliance with DOCOMO’s OREX packages was another critical aspect of the validation process, confirming that the new network architecture aligns with industry standards and best practices. The comprehensive testing and validation phase underscores the importance of meticulous planning and collaboration in achieving groundbreaking technological milestones.
Executive Perspectives and Global Implications
Executives from both StarHub and NTT DOCOMO have highlighted the transformative potential of Open RAN technology. Ayush Sharma, Chief Technology Officer at StarHub, expressed enthusiasm about bringing this innovation to the market. He emphasized that Open RAN allows StarHub to offer customizable, flexible, and value-driven solutions to its customers. This approach aligns with the company’s commitment to staying at the forefront of technological advancements and providing superior service quality.
Sadayuki Abeta, Chief Open RAN Strategist at NTT DOCOMO, discussed the freedom and cost-efficiency Open RAN offers to Mobile Network Operators (MNOs). By not being dependent on single-vendor roadmaps, operators can adopt best-in-class components from multiple vendors, fostering a more competitive and innovation-driven ecosystem. This flexibility is crucial for building advanced network infrastructures that can adapt to the rapidly changing telecommunications landscape. The collaboration between StarHub and NTT DOCOMO sets a precedent for similar partnerships globally, encouraging broader adoption of Open RAN technology.
