IEEE 802.11n-2009, or 802.11n, is a wireless-networking standard that uses multiple antennas to increase data rates. The Wi-Fi Alliance has also retroactively labelled the technology for the standard as Wi-Fi 4.

2024年6月28日 · 802.11n (also sometimes known as Wireless N) was designed to improve on 802.11g in the bandwidth it supports by using several wireless signals and antennas (called MIMO technology) instead of one. Industry standards groups ratified 802.11n in 2009 with specifications providing up to 600 Mbps of network bandwidth. 802.11n also offers a somewhat ...

2021年6月19日 · Learn about 802.11n, which is one of several industry standards for Wi-Fi wireless network equipment. It superseded 802.11a, 802.11b, and 802.11g.

2023年2月27日 · 802.11n, under its full name IEEE 802.11n-2009, is an old wireless networking standard, announced in its draft format in 2007, and finalized and published in 2009. 802.11n is also referred to as Wi-Fi 4, and it’s the first standard to allow the use of two radio frequency bands: 2.4 GHz and 5 GHz.

2025年1月23日 · This post will show you how to install or update your 802.11n WLAN driver in Windows 11/10/8/7. In addition, if you want to keep your 802.11n wireless adapter network card in good condition, or if your 802.11n device is not working properly, you should consider updating the 802.11n WLAN driver.

Discover 802.11n and learn how it stacks up against earlier wireless technologies. Also, explore how 802.11n differs from its predecessor, 802.11ac.

2022年12月27日 · With 802.11n, Wi-Fi became even faster and more reliable. You might have heard the term dual-band from LAN vendors. This means that data is delivered across 2 frequencies. 802.11n operates at 2 frequencies – 2.45 GHz and 5 GHz. 802.11n has a theoretical bandwidth of 300 Mbps.
