Dual-band Wi-Fi technology improves internet connections by operating on two distinct frequency bands: 2.4 GHz and 5 GHz. The 2.4 GHz band provides broader coverage and better penetration through obstacles, making it suitable for general use. In contrast, the 5 GHz band offers faster speeds and reduced interference but with a shorter range. By utilizing both bands, dual-band routers can optimize connectivity based on user needs and network demands. This technology enhances user experience by reducing lag and maintaining strong connections for bandwidth-intensive applications, such as streaming and online gaming.
