Apple introduced Ultra Wideband to increase the accuracy of AirDrop by offering a direction-based method to share content. This technology uses triangulation and motion to determine what it is looking for. Apple calls the chip for Ultra-Wideband, U1 chip, which offers more range than Bluetooth or Wi-Fi scanning to find specific things without relying on GPS coordinates that can be inaccurate indoors when there are walls blocking signals from satellites overhead.
What are AirTags, and How Do They Work?
AirTags work offline and will automatically ping nearby Apple devices to mark their location online. With over 1.5 billion active users of the Find My network on iOS alone, it’s possible to track any lost or stolen iPhone anywhere in the world without an internet connection because these devices are constantly pinging each other through Near Field Communication (NFC).
Users can also place their AirTag into Lost Mode, which notifies them when they’re within range of where it was last seen and if someone else has found and tagged your phone using NFC technology, so you know who stole or found your missing handset!
