Le (ou la) Wi-Fi, aussi orthographié wifi, est un ensemble de protocoles de communication sans fil régis par les normes du groupe IEEE 802.11 (ISO/CEI 8802-11). Un réseau Wi-Fi permet de relier par ondes radio plusieurs appareils informatiques (ordinateur, routeur, smartphone, modem Internet, etc.) au sein d'un réseau informatique afin de permettre la transmission de données entre eux.
Apparues pour la première fois en 1997, les normes IEEE 802.11 (ISO/CEI 8802-11), qui sont utilisées internationalement, décrivent les caractéristiques d’un réseau local sans fil (WLAN). La marque déposée « Wi-Fi » correspond initialement au nom donné à la certification délivrée par la Wi-Fi Alliance (« Wireless Ethernet Compatibility Alliance », WECA), organisme ayant pour mission de spécifier l’interopérabilité entre les matériels conformes à la norme 802.11 et de vendre le label « Wi-Fi » aux matériels répondant à ses spécifications. Pour des raisons de facilité d’usage (et de marketing) le nom de la norme se confond aujourd’hui avec le nom de la certification (c’est le cas en France, en Espagne, au Canada, en Suisse, en Tunisie…). Ainsi, un réseau Wi-Fi est en réalité un réseau répondant à une des normes IEEE 802.11. Dans d’autres pays (Allemagne et États-Unis par exemple) de tels réseaux sont aussi nommés par le terme générique WLAN : Wireless LAN (réseau local sans fil).
Grâce aux normes Wi-Fi, il est possible de créer des réseaux locaux sans fil à haut débit. En pratique, le Wi-Fi permet de relier des smartphones, ordinateurs portables, des objets connectés ou autres périphériques à une liaison haut débit. Les débits se sont accrus avec les nouvelles normes Wi-Fi. Voici les débits maximums théoriques (et réels) pour les principales normes : 11 Mbit/s (6 Mbit/s) en 802.11b (1999), 54 Mbit/s (25 Mbit/s) en 802.11a (1999) et 802.11g (2003), 600 Mbit/s en 802.11n (2009),, 1,3 Gbit/s en 802.11ac (Wi-Fi 5, 2013) et 10,5 Gbit/s en 802.11ax (Wi-Fi 6, 2021).
