5G communication evolved from 4G as a communication technology needed for the “Hyper-Connected Revolution” of the Fourth Industrial Revolution, where various industry technologies converge. The Fourth Industrial Revolution represents the convergence of ICT-based technologies and advanced digital technologies, like artificial intelligence, robotics, virtual reality, augmented reality, 3D printing, biotechnology and quantum computing, among others. This technology convergence creates a new era where “people + places + objects + products” are interconnected based on artificial intelligence. 5G is an essential communication technology that enables the Fourth Industrial Revolution and related technology convergence by realizing ultra-fast wireless communication (eMBB: enhanced Mobile Broadband), ultra-low latency reliable communication (URLLC: Ultra Reliable Low Latency Communication), and massive machine-type communication for hyper-connected objects (mMTC: massive machine type communication).
