IEEE 802.11n is an amendment to IEEE 802.11-2007 as amended by IEEE 802.11k-2008, IEEE 802.11r-2008, IEEE 802.11y-2008, and IEEE 802.11w-2009, and builds on previous 802.11 standards by adding a multiple-input multiple-output (MIMO) system and 40 MHz channels to the PHY (physical layer) and frame aggregation to the MAC layer.
The 6th generation AirPort Extreme (and 5th generation AirPort Time Capsule) featured three-stream 802.11ac Wi-Fi technology with a maximum data rate of 1.3 Gbit/s, which is nearly three times faster than 802.11n. Time Machine was now supported using an external USB hard drive connected to AirPort Extreme (802.11ac model only). [15]
Some of Ralink's 802.11n RT2800 chipsets have been accepted into the Wi-Fi Alliance 802.11n draft 2.0 core technology testbed. They have also been selected in the Wi-Fi Protected Setup (WPS) and Wireless Multimedia Extensions Power Save (WMM-PS) testbeds. Ralink was a participant in the Wi-Fi Alliance and the IEEE 802.11 standards committees. [1]
IEEE 802.11bn, dubbed Ultra High Reliability (UHR), is to be the next IEEE 802.11 standard. [9] It is also designated Wi-Fi 8 . As its name suggests, 802.11bn aims to improve the reliability of Wi-Fi .
FreeBSD, NetBSD, OpenBSD, and DragonFly BSD also provide an interface for 802.11 drivers that supports monitor mode, and many drivers for those operating systems support monitor mode as well. In Mac OS X 10.4 and later releases, the drivers for AirPort Extreme network adapters allow the adapter to be put into monitor mode.
A wireless network interface device with a USB interface and internal antenna A Bluetooth interface card. A wireless network interface controller (WNIC) is a network interface controller which connects to a wireless network, such as Wi-Fi, Bluetooth, or LTE (4G) or 5G rather than a wired network, such as an Ethernet network.
In IEEE 802.11 wireless local area networking standards (including Wi‑Fi), a service set is a group of wireless network devices which share a service set identifier (SSID)—typically the natural language label that users see as a network name. (For example, all of the devices that together form and use a Wi‑Fi network called "Foo" are a ...
Qualcomm Atheros is a developer of semiconductor chips for network communications, particularly wireless chipsets. The company was founded under the name T-Span Systems in 1998 by experts in signal processing and VLSI design from Stanford University, the University of California, Berkeley, and private industry.
