Wi-Fi

technology · wireless · internet · everyday

Radio waves everywhere. Wi-Fi works by sending information through radio waves, just like radio stations broadcast music. Your phone, laptop, and tablet all pick up these invisible signals to connect.

Works from across rooms. Wi-Fi signals travel through walls and reach devices that are far away from the router. This means you can be in your bedroom while the router sits downstairs and still stay connected.

Public hotspots. Restaurants, libraries, airports, and coffee shops offer free Wi-Fi so people can use their devices while they're out. You just need to connect to the network name and you're online.

Super speedy. Wi-Fi is much faster than older phone internet and lets you stream videos, play online games, and download files in seconds.

Needs protection. You should always use a password with your Wi-Fi to keep strangers from using it and to protect your information from being stolen.
