Wi-Fi 802.11 a/b/g/n/ac, dual-band

“Wi-Fi 802.11 a/b/g/n/ac, dual-band” refers to the wireless networking capabilities of a device, such as a smartphone, laptop, or router.

Wi-Fi 802.11: This indicates the standard of Wi-Fi technology being used. In this case, it encompasses multiple Wi-Fi standards, including 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac.

a/b/g/n/ac: These letters represent the different Wi-Fi standards supported by the device. Each standard offers various speeds, frequency bands, and compatibility with different devices. For example:

802.11a operates on the 5 GHz frequency band.
802.11b/g/n operate on the 2.4 GHz frequency band.
802.11ac operates on both the 2.4 GHz and 5 GHz frequency bands, providing faster speeds and better performance compared to older standards.
dual-band: This indicates that the device supports both the 2.4 GHz and 5 GHz frequency bands, allowing for better flexibility and reduced interference in wireless connections. Devices with dual-band Wi-Fi can choose the optimal frequency band for faster and more stable wireless networking.
