The Evolution of Mobile Networks from 5G to 6G

6G is set to redefine connectivity with speeds up to 1Tbps, sub-millisecond latency, and AI-native networks powered by terahertz spectrum. It will unlock advanced IoT, smart cities, and real-time applications like remote surgery and holographic communication. However, major hurdles remain, including infrastructure costs, spectrum limitations, energy efficiency, and global standardization.
