"In fact, most of the underlying radio technology here isn’t new — the techniques for encoding signals were invented decades ago. What’s new is that the math has been committed to silicon, and is being produced in scale. So now you can buy a radio chip for a few bucks and add it to any device."
"...these radios do some crazy math." - oh, you ker-azzzy American tech commentators. The things you say.
Some interesting shit, though.
