What is Wi-Fi?

Wi-Fi (a play on “Hi-Fi”) is a local area wireless technology that lets devices network with each other over radio frequencies. Those frequencies are the 2.4 Ghz UHF band and the 5 Ghz SHF band.

How does Wi-Fi work?

A Wi-Fi network is broadcast by a Wi-Fi router, which allows multiple devices to connect to a wireless local area network (WLAN) at once. The router subsequently connects each of those devices to the internet. Most Wi-Fi networks are password-protected.

The distance and strength of a Wi-Fi signal depend on the environment and the router, but a single home router can generally cover an entire household.
