Wi-Fi

Wi-Fi () 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 home and small office networks to link devices and to provide Internet access with wireless routers and wireless access points in public places such as coffee shops, restaurants, hotels, libraries, and airports.

OpenWrt (from open wireless router) is an open-source project for embedded operating systems based on Linux, primarily used on embedded devices to route network traffic. The main components are Linux, util-linux, musl, and BusyBox. All components have been optimized to be small enough to fit into the limited storage and memory available in home routers.

AirPort is a discontinued line of wireless routers and network cards developed by Apple Inc. using Wi-Fi protocols. In Japan, the line of products was marketed under the brand AirMac due to previous registration by I-O Data.

AirPlay is a proprietary wireless communication protocol stack/suite developed by Apple Inc. that allows the streaming of multimedia and device screens, together with related metadata, between compatible devices. Originally implemented only in Apple's own software and hardware, the company has since licensed the AirPlay protocol stack to third-party manufacturers and it has been implemented on devices such as television sets and home audio systems. AirPlay works through either a direct peer-to-peer connection between devices or through an infrastructure local network.

Miracast is a wireless communications standard created by the Wi-Fi Alliance which is designed to transmit video and sound from devices (such as laptops or smartphones) to display receivers (such as TVs, monitors, or projectors). It uses Wi-Fi Direct to create an ad hoc encrypted Wi-Fi connection and can roughly be described as "HDMI over Wi-Fi", replacing cables in favor of radio waves. Miracast is utilised in many devices and is used or branded under various names by different manufacturers, including Smart View (by Samsung), SmartShare (by LG), screen mirroring (by Sony), Cast (in Windows&n

KRACK ("Key Reinstallation Attack") is a replay attack (a type of exploitable flaw) on the Wi-Fi Protected Access protocol that secures Wi-Fi connections. It was discovered in 2016 by the Belgian researchers Mathy Vanhoef and Frank Piessens of the University of Leuven. Vanhoef's research group published details of the attack in October 2017. By repeatedly resetting the nonce transmitted in the third step of the WPA2 handshake, an attacker can gradually match encrypted packets seen before and learn the full keychain used to encrypt the traffic.

Wireless Display (WiDi) is discontinued technology developed by Intel that enables users to stream music, movies, photos, videos and apps without cables from a compatible computer to a compatible HDTV or through the use of an adapter with other HDTVs or computer monitors. Intel WiDi supports HD 1080p video quality, 5.1 surround sound, and low latency for interacting with applications sent to the TV from a PC running Windows 7 or later.

thumb|Warchalking symbols Warchalking is the drawing of symbols in public places to advertise an open Wi-Fi network. Inspired by hobo symbols, the warchalking marks were conceived by a group of friends in June 2002 and published by Matt Jones who designed the set of icons and produced a downloadable document containing them. Within days of Jones publishing a blog entry about warchalking, articles appeared in dozens of publications and stories appeared on several major television news programs around the world.

LibreCMC is a GNU/Linux-libre distribution for computers with minimal resources, such as the Ben NanoNote, ath9k-based Wi-Fi routers, and other hardware with emphasis on free software. Based on OpenWrt, the project's goal is to aim for compliance with the GNU Free System Distribution Guidelines (GNU FSDG) and ensure that the project continues to meet these requirements set forth by the Free Software Foundation (FSF). LibreCMC does not support ac (Wi-Fi 5) or ax (Wi-Fi 6) due to a lack of free chipsets.

AOSS (AirStation One-Touch Secure System) is a system by Buffalo Technology which allows a secure wireless connection to be set up with the push of a button. AirStation residential gateways incorporated a button on the unit to let the user initiate this procedure. AOSS was designed to use the maximum level of security available to both connecting devices, including both Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA).
