What is Wi-Fi
Wi-Fi is a wireless radio technology used to connect computers, including tablets, smartphones, and other devices to the internet. It is the radio signal sent from a wireless router to a nearby device, which translates the signal into data you can see and use. The device transmits a radio signal back to the router, which connects to the internet by wire or cable.
What is a Wi-Fi network?
A Wi-Fi network is simply an internet connection that’s shared with multiple devices in a home or business via a wireless router.

This gives you flexibility to stay connected to the internet as long as you’re within your network coverage area.
