What are key features which makes 6G better than 5G? Is there a 7G in works too?
Introduction
Key Features of 6G vs 5G
6G technology is expected to offer several significant improvements over 5G
Ultra-High Speed and Low Latency
6G aims to provide terabit-per-second (Tbps) speeds, compared to gigabit-per-second speeds in 5G
Latency will be reduced to microseconds, compared to milliseconds in 5G
Advanced Spectrum Utilization
6G will utilize higher frequency bands, including sub-terahertz (sub-THz) frequencies
Operating in the 30 to 300 GHz millimeter waves up to the 300 to 3000 GHz radiation range
Intelligent Network Management
Integration of artificial intelligence (AI) and machine learning for autonomous network management
AI-driven networking solutions for optimizing performance and efficiency
Enhanced Security and Privacy
More robust security protocols and privacy measures, including quantum cryptography
Higher Capacity
Support for a greater number of connected devices per square kilometer
Energy Efficiency
More energy-efficient operations through innovations in network design and AI capabilities
Global Connectivity
Aims to bridge the digital divide by extending connectivity to remote and underserved areas
7G Development
While 6G is still in the research and development phase, there are indeed early discussions and speculations about 7G:
7G is projected to emerge around the 2040s, after the full implementation of 6G
It aims to provide hyper-connectivity, ultra-low latency, and energy efficiency beyond what 6G offers
7G envisions a fully integrated global network where the distinction between local and global internet access blurs
Some countries, like Norway, Netherlands, and South Korea, are already achieving speeds and latency levels equivalent to theoretical 7G or 8G connectivity
Conclusion
However, it’s important to note that 7G is still largely conceptual. The research and standardization for 7G are in very early stages, with no standardized definition or specification yet. The focus of the telecommunications industry is currently on developing and implementing 5G and 6G technologies.
