4G networks, or fourth-generation networks, are a type of mobile communication technology that provides faster internet speeds and improved connectivity compared to previous generations. They enable users to stream videos, play online games, and download large files with minimal delays. 4G networks primarily use LTE (Long-Term Evolution) technology to achieve these enhancements. One of the key features of 4G networks is their ability to support a larger number of devices simultaneously. This is particularly important as more people rely on mobile devices for everyday tasks. Additionally, 4G networks offer better coverage and reliability, making them essential for modern communication and internet access.
