Wi-Fi is a wireless networking technology that allows devices such as computers (laptops and desktops), mobile devices (smart phones and wearables), and other equipment (printers and video cameras) to interface with the Internet. It allows these devices--and many more--to exchange information with one another, creating a network.

Wi-Fi is a wireless networking technology used by computers, smartphones, and other devices to connect to the internet or other devices. It's based on a set of wireless communication standards developed by the Institute of Electrical and Electronics Engineers (IEEE). These standards are also known as IEEE 802.11.

Wi-Fi (/ ˈwaɪfaɪ /) [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.

Wi-Fi allows devices to connect to one another the same way as when network cables are used, just without the actual cables. A Wi-Fi network is basically a wireless local network. The owner of the Wi-Fi network is in total control.

So, what is Wi-Fi? It is actually the technology that allows your devices to connect wirelessly to the internet through a modem and router. Wi-Fi is not its own specific service to buy so you won’t find “Wi-Fi” or “non-Wi-Fi” internet plans from your provider. Your internet plan represents the connection and speeds to the modem.
