What exactly are the 2.4GHz and 5GHz frequencies?

The 2.4GHz frequency range is known for its fast speed and ability to cover a wide area. It supports various technologies, including mobile devices, Bluetooth, and smart home appliances. However, the large number of users connected to the 2.4GHz band eventually became crowded and experienced decreased speeds.

This is where the 5GHz frequency comes into play. The 5GHz frequency offers even faster speeds and provides a more stable connection for all devices. The only drawback is that it doesn’t have the same wide coverage as the 2.4GHz band. Consequently, having a router that solely supports the 5GHz frequency was undesirable.

To address this issue, dual-band routers were introduced, allowing the coexistence of both the 2.4GHz and 5GHz frequencies. When new devices connect to your Wi-Fi network, they automatically connect to the faster 5GHz frequency. However, older devices or devices located far from the router will connect to the 2.4GHz band to ensure a reliable connection.

With this information about dual band routers, you can make a more informed decision as to whether this type of router is the right fit for your specific needs and network requirements.
