Development of 6G Technology

• 6G = sixth-generation wireless communication tech, expected commercial rollout circa 2030, promising terahertz (THz) spectrum, ultra-low latency, AI-native networks, and ubiquitous connectivity.
• India has moved from being a late 4G adopter to an early 6G aspirant — the Bharat 6G Vision seeks to make India a frontline contributor in design, development and deployment of 6G by 2030.
• High examinable value: links S&T (GS-III), governance (DoT/TTDF), and economy (Atmanirbhar telecom manufacturing).
