|Last year, Apple introduced the U1 chip with the iPhone 11, which provides support for ultra-wideband communication to determine the exact location of devices in space. The distance between two devices that support ultra-wideband communication can be accurately measured by calculating the time it takes for a radio wave to travel between the two devices. |
So far, Apple has only used this feature for directional AirDrop in iOS 13. However, it is assumed that the main purpose of the U1 chip is to interact with the yet-to-be-announced AirTag trackers, which, according to rumors, can be attached to various items, such as a wallet, keys or suitcase, in order to easily find the item through the Locator app if necessary.
