According to Pete: How WiFi Works
Pete digs into WiFi for a broad, hardware-ish level explanation of how it all works.
I’ve previously had a high-level understanding of WiFi's function, but not so much understanding that I could give any kind of meaningful explanation, and after digging into it more deeply, I still can’t. It’s a shockingly broad subject with a zillion facets, and one video isn’t going to do justice to the graduate-level expertise this topic surely demands. In the face of that, we’ll do it anyway! This video is for all you out there who, like me, have largely taken WiFi for granted. It should give you just enough information so you don’t get beat up at a nerd party where everybody else knows the topic better than you do.
That’s a lie. This probably won’t save you. Maybe just smile and nod.
