80211abgn

80211abgn refers to a set of wireless networking standards defined by the IEEE 802.11 family. These standards are collectively known as Wi-Fi and are used for wireless local area networks (WLANs). The "abgn" in 80211abgn represents the different frequency bands and modulation techniques used by these standards.

802.11a operates in the 5 GHz frequency band and uses Orthogonal Frequency-Division Multiplexing (OFDM) for data transmission. It supports data rates up to 54 Mbps.

802.11b operates in the 2.4 GHz frequency band and uses Direct Sequence Spread Spectrum (DSSS) for data transmission. It supports data rates up to 11 Mbps.

802.11g operates in the 2.4 GHz frequency band and uses both DSSS and OFDM for data transmission. It supports data rates up to 54 Mbps, making it backward compatible with 802.11b devices.

802.11n, also known as Wi-Fi 4, operates in both the 2.4 GHz and 5 GHz frequency bands and uses Multiple-Input Multiple-Output (MIMO) technology for data transmission. It supports data rates up to 600 Mbps.

These standards are widely used in various applications, including home networking, public hotspots, and enterprise networks. They provide a range of data rates and frequencies to suit different needs and environments.
