WiFi

WiFi, also spelled Wi-Fi, is a wireless networking technology used across the globe. It refers to any system that uses the 802.11 standard, which was developed by the Institute of Electrical and Electronics Engineers (IEEE ) and released in 1997. This standard was largely promoted by the Wi-Fi Alliance, a trade group that pioneered commercialization of the technology. A person or business can use a wireless router  or similar device to create a "hotspot" or area in which appropriate devices can connect wirelessly to a network or gain Internet access .
