They are commonly used today in their 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac and 802.11ax versions to provide wireless connectivity in homes and businesses.
- What is 802.11n? | Definition from TechTargetPublished in October 2009, 802.11n is an update to IEEE 802.11g, which supported a maximum connection speed of 54 megabits per second . 802.11n supports multi-channel utilization and dual band support for both 2.4 gigahertz (GHz) and 5 GHz frequencies with a maximum data rate of 600 Mbps.
- Understanding High Speed 802.11n Wireless Networks in Depth802.11n supports 20 or 40 MHz wide channels. 40 MHz wide channels recommended only for 5 GHz. Consists of a primary channel and a secondary channel also referred to as extension channel. Second channel must be adjacent Can be above or below primary Protection provided for 20 MHz wide client use.
- What are 802.11ax, 802.11ac, 802.11n (Wi-Fi 6, Wi-Fi 5, Wi-Fi 4)?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.
- What Is 802.11n Wi-Fi in Computer Networking? - Lifewire802.11n is an IEEE (Institute of Electrical and Electronics Engineers) industry standard for local Wi-Fi network communications, ratified in 2009. It replaced older 802.11a, 802.11b, and 802.11g Wi-Fi technologies but was superseded by the 802.11ac in 2013 and 802.11ax (Wi-Fi 6) in 2019. 802.11ay (Wi-Fi 7) is up next.
