What is 6G? How Will It Be Different from 5G?

While 5G brought ultra-fast speeds, edge computing, and IoT capabilities, 6G aims to redefine connectivity by integrating AI, machine learning, quantum computing, and space communication.

Key Differences Between 5G and 6G

Feature	5G Networks	6G Networks (Expected)
Speed	Up to 10 Gbps	Up to 1 Tbps (Terabit per second)
Latency	~1 ms	Sub-millisecond latency (~0.1 ms)
Spectrum	mmWave (24-100 GHz)	THz Waves (100 GHz - 10 THz)
Technology	Cloud, AI, Edge	AI-Driven, Quantum, Digital Twin Networks
Applications	IoT, Smart Cities, AR/VR	Holographic Communication, Brain-Computer Interfaces (BCI), Metaverse
Connectivity	Millions of devices/km²	Billions of devices/km²

Predicted Timeline for 6G Deployment

📅 2020-2025 – Research & Development (R&D), early testing.
📅 2026-2028 – Standardization and pilot projects.
📅 2028-2030 – Early deployments and adoption.
📅 2030+ – Commercial rollout of 6G networks worldwide.
