The shift to 5G is gaining momentum, offering faster data speeds, improved reliability, and the ability to support mission-critical applications and massive IoT deployments. After an initial slow adoption phase, 5G is now expanding rapidly.
A recent GlobalData forecast estimates that global 5G subscriptions will reach 5.5 billion by the end of 2027, accounting for nearly 48% of total mobile subscriptions. With this growth comes increasing network traffic and demand, as enterprises and public sector organizations deploy 5G for applications ranging from industrial automation to smart city infrastructure. So, now let investigate 5G Expansion and the Challenges of Operational Complexity along with Accurate LTE RF drive test tools in telecom & RF drive test software in telecom and Accurate 4G Tester, 4G LTE Tester, 4G Network Tester and VOLTE Testing tools & Equipment in detail.
Key Challenges in 5G Deployment
One of the most pressing challenges for service providers is achieving sustainable profitability while managing rising operational complexity. Delivering end-to-end 5G connectivity, from the core network to the edge, requires significant investment. However, many operators still rely on legacy, siloed network architectures that lead to inefficiencies, high operational expenditures (OPEX), and limited scalability.
Historically, network design and operations have been managed independently by different divisions, leading to redundant infrastructure and increased costs. The transport network, which serves as the backbone of 5G, faces added complexity due to the diversification of connectivity layers, requiring a shift toward more integrated and automated solutions.
Routed Optical Networking for a Scalable and Efficient Transport Network
To address these challenges, Routed Optical Networking (RON) has emerged as a transformative solution. Originally introduced by Cisco, RON simplifies transport network architecture by converging IP and optical layers into a single, streamlined infrastructure. This approach offers several key benefits:
- Lower Total Cost of Ownership (TCO): By reducing redundant equipment and optimizing network operations, RON can drive up to 46% TCO savings.
- Automation-Ready Architecture: Open data models and standard APIs enable service providers to integrate automation, simplifying network management and reducing operational complexity.
- Increased Capacity with Lower Power Consumption: The architecture optimizes wavelength utilization, reducing energy consumption while increasing overall capacity.
- Higher Service Availability and Sustainability: The streamlined network reduces packaging, improves recyclability, and lowers the overall carbon footprint.
By optimizing transport networks using application-aware and cloud-driven automation, service providers can enhance network efficiency, improve service reliability, and accelerate revenue generation.
NEC and Cisco: Enabling 5G Monetization
Since 2021, NEC and Cisco have been working together as global partners, collaborating with Tier-1 operators such as Telefónica to drive 5G network transformation. Their combined expertise in multi-layer, multi-vendor, and multi-domain integration has led to innovative solutions that support large-scale deployments.
NEC’s xHaul Transformation Service plays a key role in this partnership, leveraging its experience in designing and implementing integrated transport networks. By combining NEC’s network transformation services with Cisco’s Routed Optical Networking solutions, operators can modernize their infrastructure, achieving greater agility and scalability.
Key advantages of this collaboration include:
- End-to-End Automation: Reducing manual interventions and improving operational efficiency through intelligent automation.
- IP and Optical Convergence: Enhancing network flexibility and reducing complexity by integrating IP and optical transport layers.
- Scalable Network Operations: Enabling service providers to handle increasing data traffic efficiently while maintaining high reliability.
By leveraging NEC’s long-standing expertise in engineering Cisco solutions, this partnership is helping operators transition toward fully converged, software-driven transport networks.
The Future of 5G and Beyond
As industries continue to adopt 5G, its economic impact is expected to be significant. According to PwC, the global economic contribution of 5G will reach $1.3 trillion by 2030. From smart manufacturing to connected healthcare, the ability to integrate 5G into various industries will transform how businesses operate and how communities stay connected.
NEC and Cisco will continue to advance Routed Optical Networking and automation-driven solutions, supporting service providers in their efforts to scale, optimize, and monetize 5G networks. As IoT adoption accelerates and new applications emerge, network transformation will remain essential for unlocking the full potential of 5G and beyond.
