How Wi-Fi Actually Works

Right now, invisible radio waves are carrying every video, message, and web page through your walls and through the air. We call it Wi-Fi - but how does it actually work? In this video, we break down exactly what happens between your phone and your router: how digital data gets converted into radio signals, why walls slow your connection down, and why Wi-Fi doesn't even stand for anything. This is the first video in Everyday Explained - a series breaking down the everyday technology you use but never really understood. New videos every week. #WiFi #HowItWorks #TechExplained
