802.11n - definition

The Wi-Fi 4 wireless networking standard, 802.11n, was introduced by the Institute of Electrical and Electronics Engineers (IEEE) in 2009. Data transfer rates of up to 600 Mbps (Megabits per second) are provided by this device, which works in both the 2.4 GHz and 5 GHz frequency bands.
In comparison to 802.11a, 802.11b, and 802.11g, 802.11n offers faster speeds, increased range, and improved performance in areas with a large number of wireless devices. Multiple Input Multiple Output (MIMO), which enables the use of multiple antennas to increase the dependability and speed of wireless communications, is one of the fundamental technologies included in 802.11n.
Additionally, 802.11n supports both the 2.4 GHz and 5 GHz frequency bands, allowing for greater flexibility and less interference in areas with lots of wireless devices. Wider channels up to 40 MHz provide more bandwidth for faster data transfer.
In general, 802.11n is intended to give users in both home and business situations improved performance and a more dependable wireless networking experience. Even though it has largely been replaced by more recent Wi-Fi standards like 802.11ac and 802.11ax, 802.11n is still frequently used in many older devices and networks today.
