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 It superseded 802.11a, 802.11b, and 802.11g.

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

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.

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.

2022年7月9日 · IEEE 802.11n is a wireless networking standard that increases wireless local area network (WLAN) speed, improves reliability, and extends the range of wireless transmissions. It is an amendment to IEEE 802.11 and was published in October 2009.

One of the key differences between 802.11ax and 802.11n is the speed and throughput they offer. 802.11ax, also known as Wi-Fi 6, is the latest standard and offers significantly higher speeds compared to 802.11n.

2023年11月7日 · 802.11n is the first generation of Wi-Fi to support MIMO (multiple in, multiple out) data transfers. MIMO increases both a network's range and its total throughput by allowing a router to use up to 4 antennas at once.

An IEEE 802.11 Wi-Fi standard that increases transmission speeds to 600 Mbps and works in both the 2.4 GHz and 5 GHz frequency bands (see dual-band router). Although newer 802.11ac devices...
