80211agnac

802.11agnac refers to a combined set of Wi-Fi standards that define wireless local area network (WLAN) technologies. Specifically, it encompasses the 802.11a, 802.11g, 802.11n, and 802.11ac amendments to the IEEE 802.11 standard. This designation is often used informally to describe devices or networks that support the features of these various standards.

The 802.11a standard, introduced in 1999, operates in the 5 GHz frequency band and offers data rates up to 54 Mbps. The 802.11g standard, also from 1999, operates in the 2.4 GHz band and also supports data rates up to 54 Mbps, while maintaining backward compatibility with 802.11b.

The 802.11n amendment, finalized in 2009, brought significant improvements. It operates in both 2.4 GHz and 5 GHz bands and introduced technologies like Multiple-Input Multiple-Output (MIMO) to increase data rates, with theoretical maximums reaching up to 600 Mbps.

The 802.11ac amendment, released in 2013, builds upon 802.11n and primarily operates in the 5 GHz band. It further enhances performance through wider channels, more spatial streams, and improved modulation schemes, enabling theoretical data rates of over 1 Gbps. Devices labeled as supporting "802.11agnac" typically indicate compatibility with all these specifications, offering a blend of range, speed, and backward compatibility across different Wi-Fi generations. This combination allows for more flexible and performant wireless networking.
