Bending the Laws of Physics! Or, How Wi-Fi Keeps Getting Faster.

I gave this talk at !!con 2015.


Shannon’s Law tells you how fast you can transmit information over a channel with a given bandwidth and noise level. You just can’t beat the limit — until we start talking about ways you can.

Learn how adding more antennas lets you squeeze more information out of the air! (Note: this is actually the coolest!) Along the way, we’ll discuss what the silly numbers and letters on your router mean, and the fantastic bag of signal processing and programming tricks that lets you carry the internet around in your pocket!
