Apple Watch Series 6 is fresh from presentation: the new smartwatch will be available starting the day after tomorrow, Friday 18 September, and there is therefore still time to study it in detail by analyzing some details. Among the innovations that have been integrated are an always-on altimeter, a faster System in Package (SiP) S6 and new sensors that allow the measurement of oxygen in the blood. But that is not all.
Apple Watch Series 6, in fact, is the first to also integrate the U1 chip which uses the positioning technology known as Ultra Wideband (UWB) capable of providing precise position and "spatial awareness". Moreover, already last October it had emerged that the chip had been implemented to be compatible with devices other than the iPhone 11.
Thanks to this technology, a product with a U1 chip can detect its exact position relative to other devices in the vicinity, allowing new features to be implemented. Among these, for example, the possibility of using the smartwatch with greater precision as a "digital key" for new generation cars thanks to the CarKey function.
Currently, on the iPhone 11 this feature allows you to improve the accuracy of AirDrop for file transfer by detecting the closest device by showing it first in the sharing options. This chip should also find its place in the AirTags, the trackers that can debut together with the iPhone 12, which will use it to allow their detection with greater precision.
Interestingly, only the Apple Watch Series 6 has the U1 chip, not the Apple Watch SE.
