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, hotels, libraries, and airports to provide visitors.
Wardriving is the act of searching for Wi-Fi wireless networks as well as cell towers, usually from a moving vehicle, using a laptop or smartphone. Software for wardriving is freely available on the internet.
A hotspot is a physical location where people can obtain Internet access, typically using Wi-Fi technology, via a wireless local-area network (WLAN) using a router connected to an Internet service provider.
iStumbler is a utility for finding wireless networks and devices with AirPort or Bluetooth-enabled Macintosh computers.
KisMAC is a wireless network discovery tool for Mac OS X. It has a wide range of features, similar to those of Kismet.

Wi-Fi calling, also called VoWiFi, refers to mobile phone voice calls and data that are made over IP networks using Wi-Fi, instead of the cell towers provided by cellular networks. Using this feature, compatible handsets are able to route regular cellular calls through a wireless LAN (Wi-Fi) network with broadband Internet, while seamlessly change connections between the two where necessary. This feature makes use of the Generic Access Network (GAN) protocol, also known as Unlicensed Mobile Access (UMA).
A wireless site survey, sometimes called an RF site survey or wireless survey, is the process of planning and designing a wireless network, to provide a wireless solution that will deliver the required wireless coverage, data rates, network capacity, roaming capability and quality of service (QoS). The survey usually involves a site visit to test for RF interference, and to identify optimum installation locations for access points. This requires analysis of building floor plans, inspection of the facility, and use of site survey tools. Interviews with IT management and the end users of the wireless network are also important to determine the design parameters for the wireless network.
Operating system Wi-Fi support is defined as the facilities an operating system may include for Wi-Fi networking. It usually consists of two pieces of software; device drivers; and applications for configuration and management.
Skyhook is a location technology company based in Boston, Massachusetts, specializing in location positioning, context, and intelligence. Founded in 2003, Skyhook originally began by geolocating Wi-Fi access points leveraging the existing practice of Wardriving commercially.

MiFi is a brand name to describe a wireless router that acts as a mobile Wi-Fi hotspot device.
WiFi-Where was a tool that facilitated Wardriving and detection of wireless LANs using the 802.11b, 802.11a and 802.11g WLAN standards. Versions existed for the operating systems iOS and Palm OS. Originally created in June 2004 for the Palm OS by Jonathan Hays of Hazelware Software, the IP for WiFi-Where was licensed to 3Jacks Software in 2009. An iPhone version of the application was released in January 2010, but was pulled from the App Store by Apple in March 2010. The app was frequently listed as a common tool to facilitate Wardriving As of 2010, it is still available in the Jailbroken Cydia store.

KRACK is a replay attack 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.
