What is Wi-Fi?

5. Dual-Band Routers

For many years, Wi-Fi users preferred the 2.4 GHz frequency for several reasons. Not only was it compatible with most devices, but it was also less expensive. Additionally, for many years, networks couldn’t reach 54Mbps. However, because more devices began to communicate via the 2.4 GHz frequency, it became overcrowded and speeds began to slow. As a result, 5 GHz began to rise in popularity. To solve the crowding issue, dual-band routers allow devices that are closer to the router to connect to the faster 5 GHz frequency. If a device is further away, it will connect to the 2.4 GHz. This is because 5 GHz frequencies have a shorter range and cannot penetrate walls as well.
