The iPhone 11 Pro is the first smartphone that integrates ultra-wideband (UWB) technology for the spatial detection of objects thanks to a new U1 chip.
The new U1 chip from Apple use this technology to accurately locate other devices Apple that also have U1 chip. The advantage of UWB technology over other location technologies such as Bluetooth is that it can offer an accuracy of centimeters, instead of meters, which makes it easier to locate objects.
With the U1 and iOS 13 chip, when you point your iPhone at someone else's, AirDrop prioritizes that device so you can send files faster. Even though Apple has not revealed other uses of this technology, yes it promises that "there will be more."
One of those we have heard in recent days is the possibility of locating objects to which you attach special labels using the iPhone, although at the moment it is only a rumor.
