5G networks are the fifth generation of mobile communication technology, designed to provide faster data speeds, lower latency, and greater connectivity than previous generations like 4G. This technology enables more devices to connect simultaneously, making it ideal for applications such as smart cities, autonomous vehicles, and Internet of Things (IoT) devices. The key features of 5G include enhanced mobile broadband, ultra-reliable low-latency communication, and massive machine-type communications. These improvements allow for seamless streaming, quicker downloads, and more efficient communication between devices, ultimately transforming how we interact with technology in our daily lives.
