The Inner Life of UWB: A Story in Nanoseconds | PRG 26

You probably have UWB in your pocket right now. It powers AirTags and Apple's FindMy.

But how does it actually work? This session goes from the physics of impulse radio through the ranging and angle-of-arrival protocols, all the way up to Apple's Nearby Interaction API, with firsthand lessons from building on the Qorvo dev kit.

For Wi-Fi professionals, UWB fills a gap Wi-Fi location has never closed: true sub-meter precision and accurate AoA without infrastructure overhead. If you've ever wondered where precise location fits in your deployments, this talk explains what's really happening under the hood.
