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.

2009年10月29日 · Abstract: This amendment defines modifications to both the IEEE 802.11 physical layer (PHY) and the IEEE 802.11 medium access control (MAC) sublayer so that modes of operation can be enabled that are capable of much higher throughputs, with a maximum throughput of at least 100 Mb/s, as measured at the MAC data service access point (SAP).

2006年5月25日 · This amendment defines modifications to the IEEE 802.11 medium access control (MAC); the physical layer (PHY) service interface of High Efficiency (HE) and Extremely High Throughput (EHT) PHYs; and to the Directional Multi Gigabit (DMG) and enhanced DMG (EDMG) PHYs to enhance Wireless Local Area Network (LAN) sensing operation in license …

2021年6月19日 · 802.11n is an IEEE (Institute of Electrical and Electronics Engineers) industry standard for local Wi-Fi network communications, ratified in 2009.

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.

802.11n is an IEEE standard for wireless networking that boosts the speed, dependability and range of wireless transmissions in wireless local area networks (WLANs).

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.
