Apple is the first company to use Ultra-Wideband(UWB) technology in smartphones. The U1 chip mainly used in Airdrop as Apple said “the latest directional version of Airdrop”. That shows another U1 equipped device’s direction and distance using radio waves. Apple is also merging Find My Friend and Find My iPhone into a single app “Find My” in iOS 13.
Difference between Bluetooth and U1(UWB) chip
Bluetooth also does the same thing as UWB in the existing Tile tracker. This tracker works by measuring signal strength. Bluetooth is inexplicit and insecure as compared to UWB. UWB uses time-of-flight calculation for measure distance. UWB can also give the direction to another device, for example, the device is 2 feet away to the left. In the future, the new trackers will be using this latest U1 chip.
