5G Vision Summary

Core Content

The document outlines the vision for 5G infrastructure within the European ICT sector, emphasizing its transformative potential across society and the economy. It highlights the integration of telecom and IT into a unified, programmable infrastructure, the development of new services and capabilities, and the importance of sustainability, scalability, and innovation in the 5G ecosystem.

Main Points

1. 5G as a Strategic Infrastructure

• Global Impact: 5G will not only enhance mobile broadband but also enable new services and capabilities for both consumers and industrial stakeholders.
• User Experience Continuity: 5G will ensure consistent performance in challenging environments, such as high mobility scenarios (e.g., trains, airplanes) and dense or sparse areas.
• Internet of Things (IoT): 5G will provide a platform for connecting a massive number of IoT devices, enabling efficient communication and data exchange for sensors, actuators, and other smart objects.
• Mission Critical Services: 5G will natively support services requiring high reliability, global coverage, and low latency, such as public safety, vehicle-to-vehicle (V2V) communication, and remote healthcare.

2. Unified Infrastructure and Multi-Tenancy

• Convergence of Fixed and Mobile Services: 5G will integrate fixed, mobile, and broadcast services into a single, flexible infrastructure.
• Multi-Tenancy Support: Operators will offer infrastructure and network functions as a service, allowing collaboration and shared resource models.
• Virtual Pan-European Operators: The use of a unified infrastructure will support virtual operators using nationally deployed resources, promoting a single digital market.

3. Sustainability and Scalability

• Energy Efficiency: 5G will significantly reduce energy consumption through advanced hardware and software solutions, including energy harvesting and optimized power usage.
• Cost Reduction: Automation and hardware optimization will lower operational costs and support sustainable business models.
• Scalability: The infrastructure will be designed to handle the expected growth in terminal devices and traffic, with a capacity increase of up to 10 Tb/s/km² and peak data rates of 10 Gb/s.

4. Disruptive Capabilities

• Performance Improvements: 5G will offer a 1000X increase in data volume per geographical area, 100X improvement in user data rates, and 1/10X reduction in energy consumption compared to 2010.
• Latency Reduction: End-to-end latency will be reduced to 5 ms, with radio link latency reaching 1 ms for critical applications.
• Service Deployment Speed: Deployment time will be significantly reduced, aiming for complete service deployment within 90 minutes.
• Support for Diverse Traffic Types: 5G will support high throughput for video services, low energy for IoT devices, and low latency for mission critical applications.

5. Design Principles

• Flexibility and Programmability: 5G will be designed to flexibly adapt to various usage requirements and deliver converged services with a unified control architecture.
• APIs for Integration: APIs at different levels (resources, connectivity, service enablers) will support a wide range of developers and service providers.
• Cognitive and Automated Management: The use of cognitive features and advanced automation will optimize complex business objectives like energy consumption and service quality.

Key Enabling Technologies

• Wireless Technologies: 5G will support a heterogeneous set of air interfaces, including both low (below 6 GHz) and high (above 6 GHz) bands, and will integrate WiFi, LTE, and new radio interfaces.
• Optical and Wireless Integration: The architecture will combine fiber optics, wireless links (e.g., mmWave), and satellite communication to support a converged transport network.
• Software-Driven Infrastructure: 5G will leverage software-defined networking (SDN) and network functions virtualization (NFV) to enable flexible and scalable service delivery.
• Edge Computing and Fog Computing: These technologies will be used to process data closer to the source, improving performance and reducing latency.

Spectrum Considerations

• High Bandwidth Requirements: 5G will require wide contiguous carrier bandwidths (hundreds of MHz to several GHz) for high capacity.
• High-Frequency Bands: Frequencies above 6 GHz will be critical for achieving the necessary performance levels.
• Regulatory Stability: A stable and predictable regulatory environment is essential for long-term investments in 5G infrastructure.
• Spectrum Utilization: Research and careful assessment will be needed to ensure that new bands are used efficiently without disrupting existing services.

Timeline

• Commercial Deployment: The commercial deployment of 5G systems is expected to start in 2020 and beyond.
• Exploratory Phase: The exploratory phase to define 5G requirements and technical options has already begun.
• Standardization: 3GPP is expected to be the primary standardization body for 5G, with study items starting in 2015.

Conclusion

5G represents a significant leap in communication technology, offering a flexible, sustainable, and scalable infrastructure that will drive innovation across multiple sectors. It will enable new business models, support mission-critical services, and foster a larger ecosystem for technical and business development. The integration of software and hardware, along with the use of advanced technologies like SDN, NFV, MEC, and FC, will be essential in realizing these capabilities.
