iPhone 11's U1 Chip Could Spark a Revolution

· · Link

You wouldn’t know it because it wasn’t mentioned during the iPhone 11 keynote, but the new iPhones have a new chip. Called Ultra Wideband, or “U1” it’s a way for iPhones to figure out their position in 3D space relative to other U1 devices. Apple mentions the use-case of a person pointing their U1 iPhone at another U1 iPhone to send files over AirDrop. Jason Snell writes that this is just the beginning.

But the possible applications of UWB go way beyond AirDrop and tracking tags. Decawave’s Viot says potential applications include smart home tech, augmented reality, mobile payments, the aforementioned keyless car entry, and even indoor navigation. (And it’s not a power hog, either—Viot says that Decawave’s latest UWB chip uses one-third of the power of a Bluetooth LE chip when in beacon mode, as a tracking tile would be.)
