5G, or fifth-generation cellular network technology, represents the latest advancement in mobile communications, offering significantly faster data speeds, lower latency, and greater capacity compared to its predecessors. Launched commercially in the late 2010s, 5G is designed to meet the growing demand for high-speed internet access and to support a wide range of applications, from enhanced mobile broadband to the Internet of Things (IoT) and critical communications infrastructure. With theoretical download speeds of up to 10 gigabits per second, 5G enables real-time video streaming, augmented reality (AR), virtual reality (VR), autonomous vehicles, and smart cities. The technology uses higher frequency bands, such as millimeter waves, along with advanced antenna technologies like Massive MIMO (Multiple Input Multiple Output) to achieve its performance improvements. While 5G promises transformative impacts on various industries and everyday life, its rollout involves significant infrastructure investment and has raised discussions about security, privacy, and health concerns.
