Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
Intel PRO/Wireless is a series of Intel wireless products developed by Intel. These products include wireless network adapters, access points, and routers that are designed to provide high-speed wireless connectivity for computers, laptops, and other devices. Intel PRO/Wireless products use various wireless technologies, including Wi-Fi (IEEE ...
Wi-Fi Protected Access. Wi-Fi Protected Access ( WPA ), Wi-Fi Protected Access 2 ( WPA2 ), and Wi-Fi Protected Access 3 ( WPA3) are the three security certification programs developed after 2000 by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found in the ...
Antennas. Wi-Fi ( / ˈwaɪfaɪ /) [1] [a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in ...
The WPS push button (center, blue) on a wireless router showing the symbol defined by the Wi-Fi Alliance for this function. Wi-Fi Protected Setup ( WPS) originally, Wi-Fi Simple Config, is a network security standard to create a secure wireless home network . Created by Cisco and introduced in 2006, the purpose of the protocol is to allow home ...
IEEE 802.11ac-2013 or 802.11ac is a wireless networking standard in the IEEE 802.11 set of protocols (which is part of the Wi-Fi networking family), providing high-throughput wireless local area networks (WLANs) on the 5 GHz band. [ c] The standard has been retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance. [ 9][ 10]
Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks ( WLANs ). It operates in the 2.4 GHz and 5 GHz bands, [9] with an extended version, Wi-Fi 6E, that adds the 6 GHz band. [10] It is an upgrade from Wi-Fi 5 ( 802.11ac ), with improvements for better performance in crowded places.
Comparison of open-source wireless drivers. Wireless network cards for computers require control software to make them function ( firmware, device drivers ). This is a list of the status of some open-source drivers for 802.11 wireless network cards. Location of the network device drivers in a simplified structure of the Linux kernel.
