5G is the fifth generation of wireless technology, offering faster speeds, lower latency, and higher capacity compared to previous generations. It operates on a wider range of frequencies, including higher-band millimeter waves, enabling faster data transfer. With speeds potentially reaching up to 100 times faster than 4G, 5G will enhance mobile internet experiences, supporting more connected devices, including smart homes, autonomous vehicles, and industrial IoT. One of its key benefits is reduced latency, which improves real-time communication and applications like telemedicine and gaming. 5G also promises to support larger network capacities, reducing congestion in densely populated areas. However, concerns have been raised about potential health effects due to the higher frequencies used, although studies have not conclusively linked 5G to health risks. Despite challenges in rollout and infrastructure, 5G continues to expand globally.
